[GUIDE] Linux Ubuntu: Unlocking Bootloader / Rooting Nexus S
- Thread starter BlackOtaku
- Start date
This guide is quite outdated, namely the image files to download are last generation and it isn't actually required to flash clockwork recovery by hand anymore. There's an app for that.
Hi all.
I'm new here, and I have rooted my Nexus S without any issue following this good guide.
The question is: Can anybody tell me if this tutorial would work with other devices apart from Nexus S? Installing the sdk tools and without drivers issues, changing the manufacturer code, would be valid?
I'm trying to help a friend to root his Samsung Galaxy SII.
Thanks in advance.

No, to root a Galaxy s II you need Odin1.85 .Go to Galaxy S II forum to root it,they explain how . 
thx. Worked but had to change a few of the steps.
1. File is called android-sdk_r16-linux_86.tgz
7. not needed. already installed in new version of 1.
8. same but also add a file called 90-android.rules containing: SUBSYSTEM=="usb", SYSFS{idVendor}=="04e8", MODE="0666"
sudo reload udev
11. chmod +x adb
chmod +x fastboot

Yes it still stands and works.
Just get the SDK from Google.
http://developer.android.com/sdk/index.html
Fastboot is included in the SDK. No need to worry about that link to it in the op
Edit. Also download your custom recovery and root zip of choice in place of what is in the op.
Basically sub in the new files but the process itself is the same

waiting for device
follow the steps from 1 to 10
also got the sdk from google and fastboot was included
but when i start on the next section and run command "fastboot oem unlock" the terminal just tells me <waiting for device> and nothing appears on my phone.
earlier in this thread it says to update the drivers, how can i do that?
thanks for any help

Try typing sudo before all fastboot commands.
I used this guide and found it to be MUCH easier: http://nexusshacks.com/nexus-s-root/how-to-root-nexus-s-or-nexus-s-4g-on-ics-or-gingerbread/

done, thanks
for a second i thought i had the same problem even with the other howto but searching in the comments i discovered that my problem was i didn't use sudo
the command is "sudo ./fastboot-lux oem unlock"
thanks again time to mess up my phone properly now

20One thing I've noticed is there isn't a lot of documentation for getting set up and unlocking your bootloader on a Linux OS. Setting up your machine to get adb and fastboot to recognize your device takes a tiny bit of extra work on a Linux operating system, but what exactly needs to be done may not be clear to everyone. Whether it's because you're new to the Android SDK/adb, somewhat new to Linux, or can't simply can't seem to find the Vendor Code for the Nexus S. (For those who are looking specifically for this, it's '18d1', and I assume will be the same on all Nexus devices to come; If this means nothing to you right now, read on.)
Disclaimer: I take no responsibility if something goes wrong (if it does, it should be fixable though), Unlocking your bootloader voids your warranty (but you can lock it back), Unlocking the bootloader will wipe your entire phone, including USB Storage; so make a copy of all those family photos and other files you may have put onto the USB storage if you want to keep them.
For the sake of sanity, this guide assumes you are using Ubuntu. If you're using something else (or different applications), there are terminal commands offered, and you probably have an idea on how to adapt the given instructions to your Linux OS.
Preparation: Installing the Android SDK, ADB, Fastboot & Setting Up Your Nexus S to be Recognized
1. Download the Android SDK for Linux: http://dl.google.com/android/android-sdk_r08-linux_86.tgz
2. Save it in a folder of your choice. I chose to keep it in my Downloads folder, myself. If you'd like, you can rename it to the simpler name of 'AndroidSDK.tgz'. The rest of the guide will assume that you did, because I'm lazy, and it makes things simpler; it will also assume you saved it in Downloads. If you feel that you have the intuition to rename and edit the path names based on your own choices, then fine; but if you're utterly lost here, just stick with what I'm doing; download to 'Downloads', rename to 'AndroidSDK.tgz'.
3. Now that you have it, navigate to the folder you downloaded it to, right-click, and click 'Extract' to unzip it. If for some reason you cannot do this, open up a terminal and try this command:You may have to adjust the command if you didn't save it under Downloads or didn't rename the file to AndroidSDK.tgz.Code:tar zxvf /home/<your-user-name>/Downloads/AndroidSDK.tgz
4. Now, we'll install adb and some other software packages by starting up the Android SDK and AVD Manager. Start it either by:
- Navigating to your AndroidSDK folder, going to the 'tools' folder and double-clicking the file called 'android'; if a popup opens asking you what you want to do with it click 'Run'.
- Using this command:Code:/home/<your-user-name>/Downloads/AndroidSDK/tools/android
5. In Android SDK and AVD Manager, click on "Available packages". Check the box next to "Android SDK Tools, revision 8" and "Android SDK Platform-tools", and click on "Install Selected" then "Install". When prompted click "Yes" to restart ADB.
6.You should now have a folder in /home/<your-user-name>/Downloads/AndroidSDK/ called "platform-tools".
7. Download fastboot here: http://developer.htc.com/adp.html
- Save it to the aforementioned platform-tools folder.
- Now, navigate to the file, right click it, click 'Properties', go to the 'Permissions' Tab and check 'Allow executing file as program'. Alternatively, run this command:Code:chmod +x /home/<your-user-name>/Downloads/AndroidSDK/platform-tools/fastboot
8. Now to set things up so adb and fastboot recognize your Nexus.
- Type this command into a terminal:- Paste this into the blank file:Code:gksudo gedit /etc/udev/rules.d/51-android.rules- Click save and close.Code:SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666"
- Then, type the following terminal command:Code:sudo restart udev
9. Almost done with preparations! Run this command:And add this line to the top of the file:Code:gedit .bashrc
Then save the file and close.Code:#AndroidDev PATH export PATH=${PATH}:/home/<your-user-name>/Downloads/AndroidSDK/tools:/home/<your-user-name>/Downloads/AndroidSDK/platform-tools
10. Download this file and save it to /home/<your-user-name>/Downloads/AndroidSDK/platform-tools: http://www.mediafire.com/?4pe5y906zr67nfh
10.We're ready to go!
Unlocking the Bootloader on your Nexus S and Rooting
Once again, unlocking your bootloader wipes everything on your device, including USB storage. Make a backup of any files you want to keep.
1. On your Nexus S, go to Menu>Settings>Applications. Select "Development" and check the box next to "USB debugging"
2. Power off the phone, and then hold down the Volume Up button and the Power button simultaneously to get into Bootloader/Fastboot mode. Connect your Nexus to the computer via USB.
3. Run this command to unlock your bootloader: (Once again WIPES EVERYTHING!)Code:fastboot oem unlock
Hit Enter and on your phone you will be prompted to confirm the action. (Use Volume +/- buttons to choose, power button to confirm choice) Confirm. At this point you will have an unlocked bootloader.
4. Copy/paste the following into the Terminal window:Code:fastboot flash recovery /home/<your-user-name>/AndroidSDK/platform-tools/recovery-clockwork-herring.img
5. Use the Volume +/- buttons to choose the Recovery option, then press the power button.
6. In Recovery, go to 'mounts and storage' and choose 'mount USB storage'.
7. Go to this page: http://xdaforums.com/showthread.php?t=682828
About 1/5 of the way down on that page, find the link for "su-2.3.6.1-ef-signed.zip", which is the link for the Froyo version of Superuser. Control-click (right click) on that link and choose "Download Link As..." Save that file to your desktop and then copy it to the main directory of your mounted phone.
8. Click 'Unmount'. Go back to 'mounts and storage' and choose 'mount /system'. Then Go Back and choose 'install zip from sdcard'>'choose zip from sdcard'>su-2.3.6.1-ef-signed.zip
9. When it's finshed installing, reboot. You are now rooted.
Special Thanks

Michael.B.; for suggesting adding the platform-tools folder to the .bashrc file.

Feel free to leave your comments on the guide below.3Good guide for beginners, I would throw in how to update their path so they can just type adb or fastboot
Be sure to update your username above.11
Yes but don't forget to install 32 libs.
Thanks for guide
Useful !
I'm waiting for cyanogen ROM so i'll able to install
Cheers1
