Tutorial for quick unlock

First things first :-

1. What is bootloader?
> Bootloader is a piece of code that runs before android loads up. Bootloaders usually contain several ways to boot the OS kernel and also contain commands for debugging and/or modifying the kernel environment.

2. Benefits of unlocking bootloader?
> You can flash custom kernels/ROMs.
> You can ALWAYS root your device. (compelling, eh?)
> You can flash alpha builds of newer firmware ( generally newer android version ) which is under testing and not meant for end consumers.

3. Disadvantages of unlocking bootloader?
> You may void your warranty.
> You may loose some proprietary vendor software such as Bravia Engine, Download Music info etc. due to removal of DRM security keys.
> OTA updater may refuse to update your device and pop up a 'Device's software modified' message.

4. Can i unlock my bootloader?
> Go to dialer
> Type *#*#7378423#*#*
> Service info > Configuration
> Rooting status :
"Bootloader unlock allowed" - You can unlock your bootloader
"Bootloader unlock not allowed" - You cannot unlock your bootloader

Unlocking bootloader:

You can unlock bootloader in two ways:
1. Official way(Instructions Included)
2. Flashtool(Recommended)

1. Generate your unlock key by entering your IMEI. (To check your IMEI - *#06# )
2. After you have the key, use flashtool or cmd prompt to unlock. (easy?)
3. To verify, check rooting status :
"Bootloader unlock done" - Congrats, you've successfully unlocked your bootloader.

    If you backed up TA then just restore it, it will lock your TA.
    If didn't go to flashtool select UBL and relock!!

    Install PC Companion, from Flashtool you need Flashmode and Fastboot drivers. You need to disable driver signature verification if you are on Windows 8.1 +.

    Good Luck.
