HOW TO UN BRICK SONY Xperia Arc S Android Smartphone

GUYZ FROM THE REQUEST OF OUR MEMBERS WE BRING HOW TO UN BRICK

Xperia Arc S Android 

FOLLOW CAREFULLY

All of us are curious of the amazing possibilities of rooting android devices. We should always keep in mind that rooting or modifying rom/firmware contents may damage our mobile device. It is recommended  to take precautions to recover before hacking your precious device. If your phone is bricked while updating or experimenting ROM mods you can follow my instructions to get your phone back in business.

First thing I would like to remind you is about taking nandroid backups. If your phone is rooted, you can install CWM Recovery for taking nandroid backups of your phones system partitions. This is the best and easiest way to recover your phone from unexpected firmware crashes while experimenting something.

You can read about installing, setting up and accessing CWM Recovery here.

Method 1: Take nandroid backups.

If you are planning install a mode in your android device, take a nandroid backup before flashing. This will help you to easily roll back if something goes wrong or the mod fails.

Creating nandroid Backup:

• Reboot into recovery by pressing back button/power button immediately after pressing power button and select backup and restore => backup. You can press back button to go back to the main recovery menu. (You can use volume rocker buttons to scroll up/down and home button to select highlighted option. Press back button to go to previous menu.)
• If it prompts for confirmation, highlight Yes and press home home button.
• It will take some time to finish backup process.  When it is finished, all important rom files will be backed up in the phone memory card.

Restoring nandroid Backup:
You can restore nandroid backups if something goes wrong with flashing modes. First you have to try if it is possible to boot into recovery mode. If it is possible,

• Once you are in the recovery, scroll down to the option "Backup and Restore" and press home button. Choose "Restore" where you choose "Backup" to create nandroid backup. 
• Select a backup from the list (Will have time stamp of the backup so that you can identify exactly which backup you want to restore).
• Wait for the restore process to finish.
• Reboot phone by going to reboot option.

Performing above steps will help you to restore your android device to a previously created restore point.

In case your phone is completely bricked and cant boot recovery image from memory, try following steps.

• Download DooMKernel Image file. (ARC-DooMKernel-ICS-BETA-v04-lower-boot.img)

• Download Fastboot package. (Fastboot.zip)

• Extract and copy Fastboot folder to C:\

• Download and install ADB Drivers Installer tool. Check Fastboot driver while installing because we are going to need it here.

• Connect your Xperia Device to pc in fastboot mode (To connect xperia device in fastboot mode, turn off the phone and connect phone to computer via usb cable while pressing and holding the menu button.)

• If your phone is connected in Fastboot mode, the led notification light will glow in blue color.

• Complete Fastboot driver installation in your os.

• Copy ARC-DooMKernel-ICS-BETA-v04-lower-boot.img to C:\Fastboot\

• Open cmd (Win Key + R to open "Run command" window, enter cmd and hit enter key.) and navigate to C:\Fastboot\ by entering "cd C:\Fastboot" without quotes in command window.

• Enter  fastboot.exe -i 0x0fce ARC-DooMKernel-ICS-BETA-v04-lower-boot.img  (Type ARC and press TAB. No need to type whole file name) and hit enter.

• If you see a success message after few lines of information, immediately disconnect phone and try to enter recovery mode by pressing back button or volume down button.

• Try to perform nandroid restore from recovery.

If the recovery fails to load on boot or getting stuck, you will have to reflash the original firmware in order to unbrick your phone. For that, we will use a powerful tool called Flash Tool.

Recovering Bricked phone using Flash Tool

Flashtool is a flashing software that can be used to :

1. Flash original Images (Android 1.6, 2.1, 2.3 Images)

2. Root your phone

3. Install Recovery, Busybox, custom kernels

4. Clean your Rom (remove /system/apps apps of your choice) (Be careful, unless you really know what you do, do not modify the default list. This can make your phone stuck at the SE Logo)

5. Clear dalvik cache

6. Optimize (install of JIT v2) (Disabled in 0.4, will readd it as a plugin for 2.1 phones only)

7. Customize (installs apps found in the custom/apps folder of the flashtool)

8. Clean uninstalled (remove any references to system apps removed in the Clean (root needed) step)

9. Edit any text file on the device

10. Rebrand your device

Flashtool is very powerful and you don't need to understand all of its functionalities to use it for recovering your phone. Our phone is bricked mostly because the phone firmware is corrupt. We can use flashtool to flash stock firmware image to the xperia device.

First of all, download flashtools from official flashtools website and install it following instructions given in the website. (Installation tab).

You can check Sony Xperia Forums  for latest stock firmware images. If you find them outdated try to find lastest firmware images with help of google. The page also has helpful tutorials on how to flash firmware image to device. You can follow them or request me to elaborate this article.

All the best.
