How to unlock your Xperia device bootloader

[FajarMF28]

Hi bro, i just wanna help those people who wanna unlock their phone bootloader. Why you need to unlock your phone bootloader? To install some custom rom like FreeXperia's CyanogenMod 10, or Custom Kernel. First, all you need is :
1. Rooted phone. See my guide here
2. Have the driver, you can install PdaNet from my guide or Sony Companion
3. Install the flashtool from Androxyde github

YOUR PHONE WARRANTY NOW VOID!
THIS PROCEDURE DOES A FACTORY RESET ON YOUR PHONE. YOUR DATA, MESSAGES, CONTACTS, OR ANY APPLICATIONS WILL BE DELETED, AND IT WILL INSTALL A STOCK ROM LIKE THE FIRST DAY YOU BOUGHT YOUR PHONE. PLEASE MAKE A BACKUP FIRST IN CWM, I DONT OWN ANY BLAME

Make sure your phone is allowed to be unlocked. Here is the guide :
Dial *#*#7378423#*#*, then go to Service info > Configuration > Rooting Status. If the Bootloader Unlock Allowed is yes, you can continue If not, please dont ask me. If you want to unlock your phone, go to your service center

THE UNLOCKING STEPS IS :
1. Dial *#06# and takes a note of your IMEI on notepad or anything. This is needed for our next step
2. After install Flashtool, go to Drivers folder and click on Install-Drivers.exe or something like that. In the steps, you need to install your Xperia XXX (XXX is your phone model), Flashboot driver, and flashmode driver. [If your phone is Miro, select the Tipo driver]
[IF YOU ARE ON WIN7 / WIN8, when you're on booting your pc, push the F8 button, and select Disable Digital Signature]
3. Go to Unlock Bootloader website, and enter your phone IMEI here.
If you got a warning like this, then delete your last IMEI character

4. Open up your mail, and then take a note of the unlock key sent by Sony
5. Without shutdown your phone, plug on your phone to your pc. When the pop up is appear, select Tipo for your Miro
6. Click on Plugins > Bootloader Unlock > Run

7. Enter your unlock code sent by Sony

8. NOW, SHUTDOWN YOUR PHONE. Enter the fastboot mode (Press and hold the volume up button, and plug the cable. When the blue led appear, release the volume button)
9. Now, wait until it completed. Cheers, your phone now unlocked! Check it at *#*#7378423#*#*, If bootloader Unlock is yes, then you are successfully unlocking your phone
10. Enter to your CWM, and restore your data here

Thanks, and dont forget to click THANKS button

Hi, sorry for the late reply. You must have already installed CWM/TWRP (choose one). And how to enter CWM/TWRP? Just restart your phone, when the Sony logo is appearing, try to tap the volume down button repeatedly and fast. If you didnt understand, please search it on this forum

When you first boot your pc, suddenly press the F8 button, or you can go to Charm menu -> Settings -> Change PC Settings -> go to General -> Scroll down 'till you find Advanced Startup. Then select the one who have "Disable Digital Signature Check of Driver" or something

Nice, but I think it should be in the development forum, and also add a link to a CWM install tutorial.

Thank You
