How to Unlocking Bootloader on Sony Xperia W8 Using SE Tweaker Tool (Tutorial)

After i posted the way to unlocking the bootloader of the Sony Xperia X8 on this post, this time i will explain about how to Unloackig Bootloader of the Sony Xperia W8. The tutorial is a little bit same of the previous tutorial.

SE Tweaker Tool is a Tool + Guide to make some tweaks to ur phone With ease which includes of all the necessary utilities for many devices. Unlocking the bootloader of your phone will restore the original sim lock of your phone (if you had any) unless if you unlocked with EMMA/IMEI unlock code or it was factory-unlocked or if SE unlocked it! However, some users have reported that using msm7227_semc.cmd on their sim-unlocked phones did not restore the sim lock onto their phone.

Read this before doing Unlocking Bootloader

NOTE: Dealing with the bootloader is highly dangerous and can result in a hard brick if you don't follow the proper instructions. Then, you will have to go and repair your phone by sending it to SE. I am not responsible if your phone dies on you because you didn't follow instructions or you screwed up somehow. Unlock the bootloader on your sim unlocked phone AT YOUR OWN RISK!

Only For people getting error related iscoolbutton.ocx.. Just Run the ocx_fix.bat in the downloaded tool and then Run the SE Tweaker Tool..

Requirements: 
  • Rooted phone, Sony Ericsson PC Companion installed in PC, Courage
  • You do not need to have a sim lock on your phone to unlock your Bootloader.

Recommended:
  • Disable your Antivirus (it might find a "virus" in ADB.exe even though there isn't one and might even interfere in bootloader unlocking process) 
  • USB debugging enabled.

Download the files needed for the unlock.
  • Download Flashtool (needed for S1tool to work properly and for loading custom kernels next time) and install it (not necessary if you already have Flashtool):
  • Download and install Flashtool v0.5.3 here (follow instructions on the website).
  • After installing it, open the flashtool folder and open the drivers folder inside that. Double click on the ggsetup-2.2.0.11.exe file inside and install Gordon's Gate.
  • Then restart your computer. if you dont Find GORDAN'S gate.exe in the drivers folder download it from my attachments.

Steps To unlock Bootloader:
  • After installing Gordans Gate and the flashtool Turn off your phone.
  • Download SE Tweaker Tool also Mirror[Mediafire] and unzip it.
  • Run SE_Tweaker_Tool.exe from it.
  • NOTE: If no flashtool download from the dialog box appeared after running unlockbootloader.exe
  • Turn off ur phone
  • Select unlock_bootloader button.. run S1tool button to check if the your phone has SIM UNLOCK CERTIFICATE.[i.e click on "Do" in s1tool and compare the output]
  • Boot your phone into flash mode (make sure you installed Gordon's Gate and usb debugging is on). All users, press and hold back button while connecting cable from PC to phone. Continue holding back button until you get some output. The LED on your phone should flash green if it is in flash mode.
  • Click on how it should look.. it will give u an idea how the output will be..
  • NOTE- At this moment you should know if you have SIM UNLOCK CERTIFICATE or what ever the output was.. keep that in mind.. 
  • Now disconnect[/COLOR] your phone n boot it up.Connect it again to PC (make sure your USB DEBUGGING is enabled and antivirus is disabled) 
  • Now click the check box which is right for you [Read them carefully it will be according to the output you got with s1tool] run the corressponding button.. 
  • After it proceed to check if the unlocking of bootloader was done by clicking Check If your "Bootloader is unlocked And Proceed" button..
  • Reboot your phone to flashmode as before.. Run s1tool.. N compare the output.. 

If the line RUNNING S1_EROM FROM VER "#8A02$" has a lowercase "r" letter replacing the "#" (RUNNING S1_EROM FROM VER "r8A02$"), your bootloader has been unlocked . If it has an uppercase "R" replacing the "#" (RUNNING S1_EROM FROM VER "R8A02$"), your bootloader is NOT unlocked.
