Making and Restoring Backup.

Assuming you have rooted your phone and installed Xrecovery:

Making Backup:

1. In Xrecovery menu...goto "Backup and Restore".
2. Select Backup.
3. Your backup will be saved in "/sdcard/xrecovery/backup/". Copy it to a save place in your pc.

Note:

• Backup makes an image(copies) of the entire phone along with all settings,messages,applications installed,etc!
• Preferably make 2 images....
•  After doing factory reset(full wipe) which will act as a clean image.
• After Installing all required applications and settings - which can be used to make quick restore when needed. 
• DO NOT RENAME THE FOLDER!! (else you will get a md5 mismatch error during restore!)

 Restoring:

1. In Xrecovery menu...goto "Backup and Restore".
2. Select restore. Then select the folder to restore.
3. Done. :)

Rooting our Sony Ericsson W8.

Definition from Wikipedia:

            "Rooting is a process that allows users of cellphones and other devices running the Android operating system to attain privileged control (known as "root access") within Android's Linux subsystem, overcoming limitations that the carriers and manufacturers put on such phones."

Warning:
First off, let me start by saying that if you don't think you need rooting, don't root.
It can be dangerous if done wrong, so be sure you know what you're doing.
With that out of the way, let's get going then.
Rooting voids Warranty!
[ but we can unroot our device before submitting to service center... ;-) ] 

Actual Process:
We can use SuperOneClick or any of the following softwares for rooting our W8

• Flash tool,Universal Androot ,Recovery Flasher,Easy Root,Unrevoked...use google to find them.

1. Download SuperOneClick.
2. On your phone, go to Settings -> Applications and enable Unknown Sources.
3. Next, go to Settings -> Applications -> Development and enable USB debugging.
4. You also need the proper USB drivers.(Install PC Companion to get the drivers.) To check if you have them, start SuperOneClick.exe and click Driver Check. If the driver check fails, update your phone with PC Companion.
5. Now, connect your USB cable from your W8 to your computer. When connected it is VERY IMPORTANT to select CHARGE PHONE.
6. Start SuperOneClick.exe and just click ROOT. Everything should go normally. You might get a message asking you if your OS is 2.0 or higher, just go ahead and click Yes.
7. You should now be rooted! :)

Note: After rooting you will have application named SuperUser in you phone which is used to allow/deny root access to other applications.

Disclaimer: I wont be responsible if u damage your phone!

[dont worry....i have tried it myself......and you can restore your phone most of the times in case of software problems! :) ]
