Knowing how to boot your Samsung Galaxy S4 into recovery mode and download mode is extremely important especially when you are looking forward in tweaking your smartphone. Actually, you will not be able to perform official or unofficial operations on your device without having to enter the recovery (stock or custom) and download mode. So, if you are new to the Android system and want to learn more about its features, then you are in the right place; here on Android Flagship our team will develop important and useful tutorial that will teach you how to use and operate your Android based device.
However, today we will be checking on how to perform an easy task: booting into recovery and download mode. The present tutorial will be suitable with the Samsung Galaxy S4 (any model of the same) though the procedure mentioned below can be safely performed (the steps will work) on any Samsung branded smartphones. So, this is something like a general step by step guide meaning that it will work for any Samsung branded devices; of course the handsets that are being powered by the Android OS.
SGS4 Download and Recovery Mode
Now, the Galaxy S4 is one of the most powerful smartphones released on the market (it competes with the HTC One, Xperia Z and of course with the iPhone 5). Anyway, the best is that the device is running on Jelly Bean 4.2.2, which is the latest release of Android firmware. And when operating on Google’s platform we can only think about customization and optimization operations. As you know, when owning an Android device as powerful as the Galaxy S4, it is really hard not to try to obtain more power from the same. Therefore, you will be tempted in rooting, flashing a custom recovery image and updating with custom ROMs and unofficial software.
The mentioned procedures are complex ones that should be applied only by those who are used with the same – the warranty of your device will get void and if you don’t know what you are doing you can end up in bricking your Android powered handset. Anyway, as you will notice, when trying to tweak your Galaxy S4, you will also have to first learn how to boot your device into recovery or download mode.
The Download Mode usually must be accessed when updating with official firmwares. I am talking about manual updates procedures, as the OTA releases are being applied automatically. So, if Samsung or Google is releasing a new stock Jelly Bean and you need to manually update your Galaxy S4 with the same (via Odin), you will notice that somewhere during the flashing procedure you will have to boot your smartphone into download mode.
Then, you need to learn how to enter the recovery mode when dealing with more complex tasks, like rooting, installing a custom ROM firmware, making Nandroid backups, perform maintenance, optimization and customization procedures and so on. Be aware that your device is being powered by a stock recovery mode; for applying the mentioned operations you will have to replace the stock recovery with a custom one, like CWM recovery. Now, the method explained below will teach you how to boot your Galaxy S4 into stock and custom recovery mode, so you have nothing to worry about.
Anyway, that was all for now, meaning that you can check on how to enter download, or recovery mode from your Samsung branded device.
How to Boot Samsung Galaxy S4 into Recovery Mode
Turn off your phone.
Then, reboot it by pressing on Volume Up, Home and Power buttons at the same time, for a few seconds.
Release the buttons as soon as you notice the stock, or custom recovery logo displayed on your handset.
Use the recovery menu in order to complete several operations.
You can boot into Android by returning to the recovery main menu; from there just select “reboot system now”.
How to Boot Samsung Galaxy S4 into Download Mode
Similar with the recovery mode, you first have to turn off your smartphone.
Then, reboot the handset by pressing on Power, Volume Down and Home buttons together.
When the “warning” message will be displayed release the buttons.
Press Volume Up in order to confirm that you want to boot into download mode.
You can now safely connect your device with the computer as the download mode has been successfully reached.
So, that was all; I know that the process is quite easy to complete but there are users who haven’t booted their Galaxy S4 into download or recovery mode until now. If this guide was helpful for you, don’t forget to share your experience among your android friends community.
Most people realize they can boot into safe mode on a Windows box but did you know you can boot your Samsung Galaxy S4 into Safe Mode too?
Booting your Droid into Safe Mode loads the core operating system sans the crap. In other words, all superfluous apps and widgets won’t load which leaves only factory installed stuff. If your phone works fine in Safe Mode but quirky in Normal Mode then you have good reason to believe that uninstalling one or more apps will fix things.
If you’re noticing that your Galaxy S4 locks up often, the battery is draining faster than normal, or the phone takes too long to startup then booting to Safe Mode is perfect because it lets you uninstall aberrant apps and gets your phone back on track.
Booting the Samsung Galaxy S4 to Safe Mode
Hold down the power button for 2 seconds to bring up your phone options.
Confirm the power off operation…
Now as the phone boots up keep pressing the menu soft key which is immediately to the left of the Home Button.
You might feel silly tapping the bottom left side of your phone as it turns on because it won’t seem like anything is happening. That’s fine, just find the nearest vacant room, close the door and keep tapping your heart away until the Home Screen emerges.
Astute observers will immediately notice the monochrome Safe Mode insert along the bottom left edge of the screen
Log in the phone and flip through your home screens.
Only factory apps are available in Safe Mode so your phone might seem banal but it should feel more responsive.
Tap your way to Settings (tap the left menu key next to the Home button and choose Settings)
It’s hiding behind the Safe Mode screen stamp…
We want the Application Manager so touch the More tab and scroll down midway.
Start browsing through your Apps starting with the most recently installed. Unfortunately I couldn’t find an easy way to sort by install date so it looks like you can only sort alphabetically or by file size (tap the menu soft key again for those options).
When you find a potentially culpable App, tap it in the list and choose Uninstall.
Keep methodically going through each App and uninstalling one by one until you find the unruly App that’s flubbing up your phone. It’s a bit of a pain but I don’t see an easier way of doing this; however, if you’ve had better success please share your knowledge in the comments below.
Consider a Factory Reset
In more extreme cases you may want to consider a full factory reset. If you have voluminous apps and think it’ll take you more than half a day to uninstall them or if your phone has become virtually unusable it might make sense to restore your phone to the factory defaults.
This will nuke all your apps and settings so make sure you have critical items backed up first.
To start the Reset, revisit Settings and tap the Accounts tab.
Scroll to the very bottom and choose Backup and Reset. Note: If you’re in Safe Mode the word Backup is obstructed by the Safe Mode graphic in the bottom left corner of the screen.
It’s kind of hard to see the Backup and reset button but just touch and trust me – you’ll end up where you want to be.
Take a thoughtful pause… then press the Factory Data Reset button to zap your phone.
When you’re ready to get out of Safe Mode, just power down the phone normally and reboot. As your phone starts up, forget any fancy finger tapping and you’ll boot directly to normal mode.
Link2SD is an android application by Bulent Akpinar that lets you move apps and games to the 2nd partition of your SD card. Why do we have to use Link2SD when Froyo and Gingerbread’s Native Apps2sd moves the files to the SD card? Native apps2sd only moves the apk file of the application leaving other files in internal memory thus you still have to manage your on-board memory and limit your choice of apps because it will eat up your memory and later on you cannot install any files anymore. Additionally, widgets and some applications are not intended to be moved to the SD card. However, Link2SD is only for root users because it is required that your phone is ROOTED.
The idea behind the application is the same. But Link2SD has more relevant features which the Native Apps2sd lacked giving Android 1.5 and up users the chance to have a taste of what it’s like to have a big phone memory. Additional features were added by the developer to furher optimize the usage of android devices. By using Link2SD, you can move not only the application file, but also the dalvic-cache and libray files of the application. This means that data will be the only one left to consume your internal memory thus installing applications and games would be easier because you can install anything you want without worrying about the famous low memory problem. Furthermore, Link2sd covers all files even moving widgets and the unmoveable applications to the 2nd partition of your SD card.
This is a step by step guide on how you can run Link2SD on your device. This tutorial will work for both stock and cutom ROMs. For ClockWorkMod Recovery users, you can check the other guide below. Follow all the instructions carefully to eliminate possible problems.
First you have to download MiniTool Partition Wizard Manager. You can download it in the link above, download it and install it on PC.
Insert your SD card to a card reader and open it on your computer.(not via USB cable)
Back up all your files to the computer because partitioning will wipe your data.
Open Mini Tool in your computer. Locate your SD card (be careful in choosing and make sure not to choose the drive of your computer)
Right click and choose Delete.
Right click on it again and choose Create New. Create “FAT32″ partition (This is where all your media files will go. Be sure to make it bigger than the 2nd part)
Select “Create as: PRIMARY”
Next, create an ext2/ext3/ext4 partition (I suggest ext2 cause it works on all roms and kernels). This is where your apps will go. I suggest a value of 512Mb would be big enough but its your choice...
Select “Create As: PRIMARY” (make sure that it is both set to primary because it will not work if it is not set to primary)
Click the “Apply” button on the top left corner and wait for it to finish the process. Done.
Put back your SD card to your phone and switch it on.
Download and install Link2sd from Google Play Store link given above.
Open Link2sd. You will be prompted to choose between ext2, ext3, ext4 and FAT32. Select one. (Give preference in this order ext4>ext3>ext2>fat32/16, Not all may be compatible with your kernel so try each one in the order of preference and use the highest ranking one that works. ext3 is compatible with my kernel so I use that.)
It will say mount script created. Reboot your phone now.
Open link2sd and if the message doesn’t show up, you succeded.
Go to Link2sd>Settings>check the autolink (to automatically move apps upon installation)
If you already have some apps, select “move to phone” then after moving select “Create Link” (be sure to check the three files: app, dalvic-cache and library files)
To check your memory, select “Storage Info”. This will show you the current state of your internal memory, FAT32, and ext2 partition.
Now you’re done and ready to install vast amount of applications as you wish!
FOR CLOCKWORKMOD RECOVERY USERS ONLY (ALTERNATIVE METHOD)
NOTE: You can also use the instructions above. This guide will work on both stock and custom ROMs.
Back up all your files to your computer. Partitioning wipes the files of your SD card.
Go into recovery mode
Select “Advanced”
Select “Partition SD card”
Choose your SD-ext size (if you’re using a 2Gb SD card, choose 512Mb. If your SD card is 4Gb or greater, you can choose 1024Mb)
Select 0 swap
Wait for the process to finish. Reboot.
Download and install Link2SD from Google Play Store.
Open Link2SD you will be prompted to choose between ext2, ext3, ext4 or FAT32. Choose ext4.
To begin, Rooting is the process whereby one can gain advanced control over their devices.
Advantages of ROOTING:
Delete unwanted apps
Expand system memory
Theming your device
Moving apps to SD-Card
Installing Firewall
many more
But the disadvantage which follows is:
WARRANTY BECOMES VOID (you can always gain it back by installing Official Firmware)
P.S: I am not responsible for anything which goes wrong. The process mentioned has been tried several times and is universally recognized. Therefore if anything goes wrong it'll be Your and solely your fault. PS: This Rooting method is only for people on 2.3.x Firmware i.e GINGERBREAD. Pls do not follow this if you are on Froyo.
Once off, press HOME and POWER button until you come to a screen like this.
Using Volume Up and Down key select Option APPLY UPDATE FROM SDCARD. Press HOME key to select the option as touch won't work.
Then select CHOOSE ZIP FROM SD CARD.
Now select the file you downloaded her.
After installing finishes go back and Reboot Device.
Congrats you have finished rooting your device.
To UNROOT Simply download Unroot.zip and follow Steps 2 to 5.
Install CM for Samsung Galaxy Ace (cooper) Note: DISCLAIMER Modifying or replacing your device's software may void your device's warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.
Installing a custom recovery
Download ClockworkModRecovery kernel (Applicable to Gingerbread only)
Once the CWM zip file is downloaded, place it to your sdcard.
Now reboot in recovery mode by holding Home & Power buttons.
Select Apply Update from SDcard and select the CWM zip file placed in your sdcard.
Restart. For verifying, go into recovery again. You will find that recovery has been updated to CWM Recovery.
For the instructions following after this, the phone needs to be turned ON (either normally or in CWM Recovery).
Installing CyanogenMod from recovery Note: Some devices do not have removable SD cards. Regardless, there should still be a partition on the device named "/sdcard" that can be used for flashing purposes, even though the contents of /sdcard may actually be in internal storage.
Download the prebuilt release of CyanogenMod you wish to install. (Or if you've built CM yourself, look in the $OUT directory for the .zip.)
Optional: Download any supplemental 3rd-party applications packages for the device you wish to use.
Place the CyanogenMod rom .zip file on the root of the SD card using adb:
Transfer your file(s): adb push YOURROMZIP.zip /sdcard/
If you boot directly to recovery and have an internal sdcard, you may need to run adb shell mount /sdcard or mount data through the recovery menu before transferring.
If you see "error: device not found" there is likely a driver issue on the PC.
If you see "error: insufficient permissions for device", try "adb kill-server" and then run "adb devices" to see if the device is attached.
On some devices, the zip file can be copied to the device using standard USB Mass Storage or MTP support. Boot the device normally and transfer the file to it.
Optional: Place any supplemental packages (e.g. Google Apps or kernel) .zip file(s) on the root of the SD card.
Boot to recovery mode on the device by holding Home & Power button until Samsung logo appears, then release Power.
Once the device boots into the ClockworkMod Recovery, use the physical volume buttons to move up and down. On most devices, the power button is used to confirm your selection, although for some devices the power button is used as a "back" button to go up one level, in which case the home button is used to confirm the selection.
Optional/Recommended: Select backup and restore to create a backup of the current installation on the device.
Select the option to wipe data/factory reset.
Select install zip from sdcard.
Select choose zip from sdcard.
Select the CyanogenMod file you placed on the sdcard. You will then need to then confirm that you do wish to flash this file.
Optional: Install any additional packages you wish using the same method.
Once the installation has finished, return back to the main menu, and select the reboot system now option. The device should now boot into CyanogenMod.
We love Android, but rooting your phone can give you the opportunity to do so much more than your phone can do out of the box — whether it’s speeding it up with overclocking or customising the look of your phone with themes. Here’s how to root some of the most popular phones with minimal effort.
Rooting, for those of you that don’t know, means giving yourself root permissions on your phone (we’ve heard all the “root” gags before, thanks). It’s similar to running programs as an administrator in Windows, or running a command with “sudo” in Linux. With a rooted phone, you can run more apps (like backup or tethering apps), as well as flash custom ROMs to your phone, which add all sorts of extra features. If you’re on the fence about rooting, check out our top 10 root-only apps that make it worth the hassle.
There are lots of different Android phones out there, and while some rooting methods might work for multiple phones, there is no one-size-fits-all guide for rooting every one of them. As such, we can’t show you how to root every phone in existence, especially since we can’t test every method. So we’re going to post methods for the most popular Android phones and keep it updated as new phones come out.
Glossary of Rooting Terms
As you learn more about the rooting process, you’ll probably run into a bunch of terms that can be confusing. Here are some of the most important ones and what they mean.
Root: Rooting means you have root access to your device — that is, it can run the sudo command and has enhanced privileges allowing it to run apps like Wireless Tether or SetCPU. You can root either by installing the Superuser application — which many of the below root processes include — or by flashing a custom ROM that has root access included.
ROM: A ROM is a modified version of Android. It may contain extra features, a different look, speed enhancements, or even a version of Android that hasn’t been released yet. We won’t discuss ROMs in depth here, but if you want to use one once you’re rooted, you can read more about doing that here.
Flash: Flashing essentially means installing something on your device, whether it be a ROM, a kernel or something else that comes in the form of a ZIP file. Sometimes the rooting process requires flashing ZIP file, sometimes it doesn’t.
Bootloader: Your bootloader is the lowest level of software on your phone, running all the code that’s necessary to start up your operating system. Most bootloaders come locked, which keeps you from rooting your phone. Unlocking your bootloader doesn’t root your phone directly, but it does allow you to root, then flash custom ROMs if you so desire.
Recovery: Your recovery is the software on your phone that lets you make backups, flash ROMs and perform other system-level tasks. The default recoveries can’t do much, but you can flash a custom recovery — like ClockworkMod — after you’ve unlocked your bootloader that will give you much more control over your device. This is often an integral part of the rooting process.
ADB: ADB stands for Android Debug Bridge, and it’s a command line tool for your computer that can communicate with an Android device you’ve connected to it. It’s part of the Android Software Developers Kit (SDK). Many of the root tools below use ADB, whether you’re typing the commands yourself or not. Unless the instructions call for installing the SDK and running ADB commands, you won’t need to mess with it — you’ll just need to know that it’s what most of the tools use to root your phone.
S-OFF: HTC phones use a feature called Signature Verification in HBOOT, their bootloader. By default, your phone has S-ON, which means it blocks you from flashing radio images — the code that manages your data, Wi-Fi and GPS connections. Switching your phone to S-OFF lets you flash new radios. Rooting doesn’t require S-OFF, but many rooting tools will give you S-OFF in addition to root access, which is nice.
RUU and SBF: ROM Upgrade Utilities (for HTC phones) and System Boot Files (for Motorola phones) are files direct from the manufacturer that change the software on your phone. RUU and SBF files are how the manufacturers deliver your over-the-air upgrades, and modders often post leaked RUU and SBF files for flashing when the updates haven’t been released yet. They’re also handy when downgrading your phone, if a rooting method isn’t available for the newest software version yet. You can flash RUUs right from your HTC phone, but Motorola users will need a Windows program called RSD Lite to flash SBF files.
Most Android Phones: The SuperOneClick Method
The majority of you will be able to use previously mentionedSuperOneClick for Windows to root your phone. So far, it’s been officially tested on the following phones:
Acer Liquid Metal
Dell Streak
HTC Magic (Sapphire) 32B
LG Optimus 2x
Motorola Defy
Motorola Flipout
Motorola Milestone
Motorola Milestone 2
Nexus One
Samsung Galaxy Ace. Note: SuperOneClick only works on the Galaxy Ace running 2.2.1 and below. If you have 2.3 or above on your phone, you’ll need to follow the steps at this XDA thread to root your phone.
Samsung Galaxy S
Samsung Galaxy S II
Samsung Galaxy Tab
Sony Ericsson Xperia X8
Sony Ericsson Xperia X10
However, it should work on many more. Forum threads abound on the internet where people claim it works with other devices, and they just haven’t been added to the “official” list. With that in mind, I’d recommend checking the rest of the methods on this page before you try SuperOneClick, to see if your phone already has an alternative method.
Also, if you want to double-check that SuperOneClick will work with your phone, a quick Google (e.g. superoneclick motorola milestone) will probably reveal whether it’s compatible.
What You’ll Need
A Windows PC: SuperOneClick has ports for Mac and Linux, but it’s pretty complicated to get it working. I haven’t used it myself, but you can check out its XDA Developers thread for more information. For the purposes of this guide, we’ll assume you have a working Windows PC to get this working. If you don’t have one, borrow one from a friend — after all, you’ll only need it once.
The USB Drivers for Your Phone: In order for your phone to fully communicate with your PC, you’ll need its USB drivers. To get them head to your phone’s manufacturer’s website and search for them on the Support page. Note: You can now grab an automatic driver installer at the SuperOneClick page on XDA and skip this step — though you can always download the drivers yourself if you so choose.
Previously mentionedSuperOneClick: This is the Windows program that will root your phone. It’s portable, so just download it and unzip it somewhere safe — no installation necessary.
The Process
First, find, download and install the USB drivers for your particular phone, if necessary. You can generally do a Google search for your device’s drivers, but you can just head to your manufacturer’s website too (e.g. HTC users will head to HTC’s website) and navigate to your device’s support page. Go ahead and install the drivers once they’re downloaded. Note: Again, you can now grab an automatic driver installer from SuperOneClick’s XDA page and skip this step if you so choose.
Next, make sure your phone is in USB Debugging mode. Head to Settings > Applications > Development, and check the USB Debugging box at the top.
Once you’ve done all that, start up SuperOneClick. Plug in your phone (make sure NOT to mount the SD card), and hit the “Root” button to root your phone — it’s that simple. When it finishes, you’ll see a message that says “Root files have been installed!” Hit Yes if it asks you to run a test, and if everything went according to plan, it should confirm that you have root permissions. You can now close out of the app.
To double check and make sure everything went well, when you open up your app drawer you should see an app called “Superuser”. If so, you’re good to go! You can now flash custom ROMs, run root-only apps and more. See the “What Now?” section below for more ideas.
Certain HTC Phones: The Unrevoked Method
If you’re running an HTC phone from 2010 and earlier, chances are you’ll need to use the Unrevoked tool. More specifically, Unrevoked roots the following phones:
If you have an HTC phone that isn’t supported by either method, Unrevoked may be working on support for it — they’re still actively developing the program and doing a great job. It usually takes them a few months, but once they get it up and running, it’s worth it. Unrevoked’s one-click method is a ton easier than the manual hacking you’ll have to do if you want root access right after a phone is released.
What You’ll Need
A Computer: Thankfully, Unrevoked is available for Windows, Mac and Linux. So as long as you have a PC handy, you can run it.
Previously mentionedUnrevoked3: When you head to Unrevoked’s website, you’ll see a list of phones. Click on yours, and you’ll probably be presented with two options — for a traditional root, you’ll want to make sure you download the “Unrevoked3″ tool, not “Unrevoked Forever”. It will automatically detect your operating system (Windows, Mac or Linux), so just hit the download link to grab the appropriate version.
HBOOT Drivers (Windows only): Windows users using Unrevoked will need to install a few drivers to get it working properly. Mac and Linux versions should be a plug-and-go affair.
The Process
If you’re running Windows, the first thing you’ll want to do is install the Unrevoked modified USB drivers (Mac and Linux users can skip the next two paragraphs). Download the drivers from this page, and extract them somewhere you’ll remember. Turn off your phone, then reboot into the HBOOT menu by holding the volume down button and then holding power. You should boot into a white screen. Plug your phone into your computer via USB, and wait for your phone to say HBOOT USB PLUG.
When it does, head to Start and search for Device Manager. Start it up and head to “Other Devices”, where you’ll see an “Android 1.0″ device. Right click on it and hit Update Driver Software. Click “Browse my computer for driver software” and navigate to the folder you extracted earlier. Hit next and let it install. If you get any warnings, just hit OK. When you’re done, and you should see the Device Manager now lists an Android Phone with “Android Bootloader Interface” under it.
Next, make sure your phone is in USB Debugging mode. Head to Settings > Applications > Development, and check the USB Debugging box at the top.
Now, start up the Unrevoked tool and plug in your phone (again, make sure to hit “charge only”). It should do everything for you automatically. Make sure you wait until Unrevoked says “Done” before unplugging your phone. If you open up your app drawer and see an app called “Superuser Permissions”, you’re done and can continue to flash custom ROMs, use root only apps and more (see the “What Now?” section for more inspiration).
Newer HTC Phones: The Revolutionary Method
From the makers of Unrevoked comes Revolutionary, a great new tool that unlocks the bootloader of many new HTC phones. This won’t actually root your phone, but after unlocking the bootloader, you can flash ClockworkMod Recovery and then flash a ROM of your choice, meaning you can flash a ROM that gives you root access. Currently, Revolutionary is in developer preview, but you can download it and try it on these supported phones:
A computer: You’ll need either a Windows or Linux computer to run Revolutionary.
Revolutionary: At the bottom of the page, you’ll see downloads for both Windows and Linux. After you click on one, you’ll be asked to name your phone, your HBOOT version, and enter your serial number, which will give you a beta key allowing you to use the program. You can find both your HBOOT version and serial number after you start up the program.
HTC Fastboot Drivers (Windows only): Windows users using Revolutionary will need to install a few drivers to get it working properly. Linux users won’t need these.
The Process
To unlock and root your phone with Revolutionary, first download the program as described above and extract the files to your desktop. If you’re on Windows, grab the HTC Fastboot drivers and install them as well. On your phone, head to Settings > Applications > Development, and make sure USB Debugging is turned on. Plug in your phone, and make sure it’s set to “Charge Only”.
Start up Revolutionary and make not of your HBOOT version. Head back to Revolutionary’s download page and pick your HBOOT version from the drop-down menu. The Revolutionary command prompt window should also list your serial number; copy that and paste it into the beta key box. Hit OK, copy your beta key, and then paste it into the command prompt. Revolutionary will root the phone, and reboot it a few times — just let it do its thing.
When it prompts you to download ClockworkMod Recovery, type Y and press Enter. If all goes well, it should flash ClockworkMod Recovery to your device, which allows you to root your phone and flash custom ROMs. Again, this will take a while; let your phone work. If it doesn’t work, you should be able to flash ClockworkMod by downloading ROM Manager from the Android Market and flashing it from the top option on the app’s home screen.
When all that’s done, you still need to gain root access to your phone. Download this ZIP file and put it on the root of your SD card (without extracting it). Shut down your phone, and boot it up into HBOOT. Usually this means holding the volume down button and then pressing the power button, though it may differ from phone to phone. Choose Recovery from the menu (using your volume rocker) and press the power button to enter ClockworkMod.
Once inside ClockworkMod, choose “Install ZIP from SD Card”, then pick “Choose ZIP from SD Card”. Choose the ZIP file you just added to your SD card, and let it do its thing. When you’re done, head back to the main menu and choose “Reboot System Now”. Once you’ve rebooted, check your app drawer for the Superuser app. If it’s there, you’ve achieved root, and you can get on to the really fun stuff (see the “What Now?” section at the bottom for ideas).
Newer Motorola Phones: The Pete Method
As you’ve undoubtedly heard, Motorola has gotten pretty controlling with its most recent phones, so SuperOneClick no longer works if you’ve updated Android to 2.3 Gingerbread. Luckily, in an attempt to root his Droid 3, developer Pete created a program that roots a number of Motorola phones, after which you can remove bloat and do whatever else you want to them (though certain phones may have a harder time flashing custom ROMs and kernels — you’ll need to search for specific methods related to your phone). Phones known to work with Pete’s Root Tool are:
Motorola Milestone 2
We haven’t tested this one ourselves, so we won’t go through the detailed process here. Hit the link below to download the program and see how it works.
The Desire Z is a special case. If you’re running 2.3 or above, you need to downgrade your phone back to 2.2 using this very involved method, then use a tool called Visionary to give it temporary root, and then go through a bit of manual hacking to make that root permanent. None of the Lifehacker editors have a Desire Z to test this on, but you can hit the link below to try it out for yourself. I’d also recommend heading over to The Unlockr for their video of the first step, using Visionary.
Rooting the Galaxy Nexus is a simple matter of unlocking the bootloader and installing the proper superuser binaries. You have quite a few options, including a fairly simple flashing method that you can read about at the link below.
Rooting the Galaxy S II is fairly easy, as long as you have a Windows PC handy. Like its predecessor, the Galaxy S, the Galaxy S II has many variants, meaning there’s no one rooting method that will work for everyone. Your rooting method will depend on which carrier you’re on, as well as what country you’re in. Non-US users with the i9100 version of the phone can check out this method. Be extra sure you’re following a guide for your specific device — most guides will have country codes that can help you find the right one.
For now, most of the guides require that you have the Samsung drivers for Windows and a program called Odin, which you’ll find in the guide for your phone. Odin will flash the ClockworkMod recovery to your phone, which you can use to push the Superuser app to your device, which gives you root access. You can then also flash ROMs and other things from ClockworkMod, if you so desire.
For more information, check out the All Things Root guides for the international Galaxy S II over at Android Forums.
What Now?
Now, the world is your oyster. Here are some things you can do:
Troubleshooting Problems
If you run into a problem rooting or flashing a ROM on your phone, we’ve written a guide to troubleshooting an almost-bricked Android phone. Be sure to check that out, as well as the instructions below on how to unroot your phone if worst comes to worst.
Unrooting Your Phone
If, in the end, you decide you want to go back to your over-the-air updates, stock ROM and unrooted goodness, you can unroot your phone. The process is a bit different for every manufacturer and every device, but these guidelines should get you on the right track.
This will return it to exactly how it was when you bought it from the store. You’ll lose all your apps, settings, ClockworkMod recovery and you’ll get over-the-air updates again.
For Motorola Phones: If you have a Motorola phone, you’ll need to use RSD Lite, the program that Motorola and its partnered carriers use to restore almost-bricked phones. RSD Lite isn’t exactly an official program open to the public, so you’ll have to Google around to find a version that works for you. You’ll also need an SBF file for your device, which is the original stock ROM that RSD Lite will flash to your phone. Google for this as well. RSD Lite only runs on Windows, so if you’re a Mac or Linux user, you’ll need a Windows partition or a friend with a Windows machine to help you out.
For HTC Phones: HTC phones can flash stock ROMs, known as RUUs, right from the phone’s bootloader. You’ll need to Google around for your device’s specific RUU file, but once you download it, save the ZIP file to your SD card and rename it (to something like PG05IMG.zip — the download page for the RUU file should specify which filename is required), booting up your phone should automatically flash the stock ROM from HBOOT, HTC’s bootloader. Check out the video at the left to see an example of this on the HTC Thunderbolt.
For Samsung Phones: If you’re using a Samsung Galaxy phone, you can use a tool called Odin to reflash an OPS file, which is a stock ROM that will return your phone to factory settings. You’ll need a Windows machine and a copy of Odin, which you can find by Googling around the net (as its not an official tool). Check out the video to the left to see an example of Odin, and check out The Unlockr’s guide to using Odin to familiarise yourself. You may need to Google around for your specific device’s OPS file and instructions.
This guide should have you up and running with root permissions on nearly every Android phone out there.

《觀察憤怒和挖苦對創造與分析思考的影響(The Effect of Observing Anger and Sarcasm on Creative and Analytic Thinking)》研究顯示，相較於直白的敘述，嘲諷的挖苦是一種層次複雜的語言表達方式，需要更多理解能力，還有相應的社會文化背景。但是太頻繁挖苦別人還是會惹人嫌的喔，千萬不要為了耍小聰明而失去重要的人情。
