Second: This root method is originally intended for the Droid Bionic and I take no responsibility if this bricks your phone.
Third: This root was discovered by JRW 28 So give him some love with that thanks button.
If you are on 2.3.6:
Install the OTA and upgrade your phone to 2.3.6
Download the 2.3.6 root zip from HERE
Make sure you have the right drivers installed then connect your phone to your PC.
Unzip the file and then double-click "Click-To-Root.bat".
Refer to the trouble shooting step bleow the 2.3.5 method if you are unable to attain root!
If you are on 2.3.5:
Root: I used the Lazy One Click and it worked perfectly, others have had success with the full manual method.
I am a manual man, I don't use 1 clicks so I will post this the only way I know how...
Download the follow file: it contains the exploit, su, Superuser
Download exploit ---> Exploit.zip
1) Unzip contents of folder to your Desktop
2) open a command terminal and navigate to the folder (cd Desktop/Exploit)
3) type the following commands
---> adb push zerg /data/local
---> adb push su /data/local
---> adb push Superuser.apk /data/local
---> adb shell
---> cd /data/local
---> chmod 777 zerg
4) Wait for the root to be gained
5) type the following commands
---> adb shell (only type this if you are no longer in shell@targa)
---> mount -o rw,remount /dev/null /system
---> cat /data/local/su > /system/bin/su
---> cat /data/local/Superuser.apk > /system/app/Superuser.apk
---> chmod 4755 /system/bin/su
---> chmod 4755 /system/app/Superuser.apk
For the lazy I made you a 1-click ---> 1-click-exploit.zip
Important for those using Oneclick:
1.Extract the files from 1-click_exploit.zip.
2.Enable USB debugging. Do so by going into your settings, then to applications, then to development.
3.Set your connection type to charge only. You can change your connection type through the notification bar once your are connected.
4.Make sure you go to Settings, Applications, and check Unknown sources if you haven't done so already.
5.Click runme.bat while your phone is connected. Be patient and let the program do it's thing. YOUR PHONE WILL REBOOT! Do not be alarmed as this is normal. Your phone should now be rooted.
If runme.bat hangs after daemeon starts:
1.First make sure you have USB Debugging, Unknown Sources, and Charge only connection enabled
2.If none of these options work, uninstall your drivers and download and install one of these:
