[Upgrading, Modifying and Unlocking] Dengabhi:
First things first:

1. Rooting essentially means you are fiddling with the installed OS. This may at times turn ugly and may result in permanent bricking of your phone (simple terms: your device will be dead, wont boot up).

2. Most companies do not entertain warranty claims for a rooted device, obviously because you have unlocked their software.

Ready to take the above risks?? Read On: :cowboy:

ROOTING GUIDE:

1.	Charge your device to 100%

2.	Go to settings/development and check the USB debugging mode to : Enabled.

3.	If you have never ever connected your device to PC, connect it via USB cable. You will see that the drivers for your device will get installed.

4.	Download UnlockRoot Pro v3.2 (free version) from : http://www.unlockroot.com/download.html

5.	Run UnlockRoot.

6.	Click root device on left panel of the UnlockRoot UI.

7.	Wait till it says : your device is rooted.

8.	Your device 'may' restart. Let it restart.

9.	Check for 'Superuser' app in your app drawer.

10.	Can you see 'Super User' app?? Congo!! Your device is now rooted.

Hey Wait !! Since you are now rooted. You can now install ClockWorkMod recovery on your device. With all the tinkering you will now do on your device, since its rooted, it becomes very important to install a 'System Backing up' tool on you phone. Every time you want to fiddle with your system, make a back up of your entire device (includes OS/Settings/Apps/Data) on an external SD card; so that if something goes wrong, you can restore your backup and your device will be good again (just like recovery point system in Windows OS).

INSTALLING CWM and MAKING BACKUP.

1. Be doubly sure that your phone is rooted and charged to 100%.

2. Download CWM.zip file from the attachments at the end of this post.

3. Transfer the CWM.zip file to the external memory card on you device, with the help of USB cable.

4. Switch off your device.

5. Press power + volume (-) button together until you see an android logo. The moment you see the logo, release the buttons.

6. You will next see an android bot logo, with his heart ripped :p and and exclamation mark on it. He's heart broken that you are fiddling with him. :p

7. Dont freak out. Now press volume (-) button again and you will see the default recovery manager.

8. Scroll down by pressing volume (-) button, to 'install zip from ext card' option.

9. Select this option by pressing volume (+) button.

10. A new window will open.

11. Scroll down to install from 'external storage' option. Press volume (+) button to select.

12. A new window showing all contents of your SD card will come up.

13. Scroll down and select CWM.zip file. Press volume (+) button to select.

14. The zip will get installed. A new windows will open up showing the CWM recovery manager.

15. Congo !

16. Now lets take 1st backup of your System. Scroll down to backup/restore option and press power button to select.

17. Scroll down to backup and select. Backing up will start. Once finished you will be redirected to the home window of CWM.

18. Now. Scroll down to reboot system option. Press POWER button to select.

19. Your system will shut down. Manually boot up your device again.

* Be careful with the controls for 'scroll' and 'select' in default and CWM recovery. Both are different. Follow the above instructions carefully. * Every time you want to back up/restore your system you have to repeat the above steps. I have not flashed the default recovery with the CWM, so that you always have the stock recovery working, in case everything else fails.

____________________________________________________________________________________________________________

TO RESTORE A SYSTEM IMAGE YOU CREATED EARLIER WITH CWM.

1. Follow steps 1 - 15 in the above tut.

2. Once you are in CWM recovery. Scroll down to backup/restore option and press power button to select.

3. Scroll down to 'Restore' option and select.

4. Choose the backup image you want to restore. Press power button to select.

5. System restore will start and finish.

6. Reboot.

Always do a backup before you try to uninstall any system app. Never uninstall any app about which you are not sure, what it does. Follow your gut feeling.
