[HOW-TO] Unlock bootloader on X8, W8, X10 mini and mini pro

Basically this is just a tutorial for those wanting to unlock their bootloader.

Before I start I must emphasise the fact that meddling with the bootloader is highly dangerous and will result in a hard brick if you don't follow proper instructions. Then, you will have to go and repair your phone at a SE shop . I am not responsible if your phone dies on you because you didn't follow instructions or you screwed up somehow. I must also mention that this will probably void your warranty (rooting already probably voided it though) and that there is NO WAY to relock bootloader as of now.

Still interested? Details are below.

Requirements: Rooted phone, phone drivers preinstalled in PC, Courage

Recommended: Use stock rom (I managed to unlock bootloader on GingerDX v013 though and users have managed to unlock it in Froyobread v23b)

Note: Unlocking the bootloader of your phone will restore the sim lock of your phone! (if any)

1. Download the files needed for the unlock at the bootloader unlock thread.

2. Unzip the files into an appropiate location on your PC.

3. Connect your phone to your computer.

4. Enable USB debugging on your phone.

5. This step will vary depending on whether you have sim unlocked your phone. If yes, jump to step 5a.
If no, run msm7227_semc.exe in the directory you unzipped the unlocking files to and press any key to start the unlocking process. Go to step 5b.

5a. If you sim unlocked your phone using anything other than SEtool, you can't unlock your bootloader for now . If you sim unlocked your phone with SEtool, then run msm7227_setool2.exe in the directory you unzipped the unlocking files to and continue to step 5b after pressing any key to start the unlocking process.

5b. Open the example log included in the files. Wait 5 minutes. Then, compare the text in the command window to those in the example log. They should be similar. Also, the last message on the command window should be Press any key to continue.

6. Disconnect your phone from the PC. Congratulations, your phone is now bootloader unlocked!

Benefits of unlocked bootloader: Custom kernels, recovery in kernel (no more accidents involving formating /system and having to reflash stock because recovery is gone), GPU overclock, swap support, modules loaded in kernel, conversion of /system etc to ext4 resulting in faster phone, full support for custom roms.....
The possibilities are endless .

[X8 and W8 only section]

You only can have the benefits when you flash a custom kernel or some sort of fix. Unlocking the bootloader allows you to do this. Currently there's no purpose in unlocking your bootloader but you can think of this as a preparation step for the future.

It is impossible to find out if your bootloader has been unlocked successfully using the tool as of now.
