Huawei has sent to many users a code composed only of numbers that seems the SIM Unlock code. However it has worked to Unlock the Bootloader. Try it, you don't lose anything.

Greetings.


That's the first thing i did. Tried it and it didn't work. This morning i received a second reply with the correct code and this time it worked.
Forgot that after bootloader unlock it does a wipe... so that's something to remember :)

What wipe? Does it wipe the internal memory?

Nope. The 2gb partition stays intact.

You must install adb & fastboot packages (search in Google) and you must open a terminal and put the following command:

sudo fastboot oem unlock 123456789987654321

To make things straight here are the steps to install a custom ROM once you have your unlock code.
1) Pull out your battery and wait for 5 secs. Insert it and open the phone in fastboot mode by holding volume down key + power. Connect your phone to pc.
2) Verify you are on stock bootloader and locked by issuing "fastboot oem get-bootinfo" it should say LOCKED. If no look for a thread here about "relocking/return to stock bootloader"
3) Unlock the bootloader by issuing the command "fastboot oem unlock myunlockkey" . Verify your bootloader is unlocked by doing "fastboot oem get-bootinfo" it should say UNLOCKED.
4) Flash your custom recovery by issuing the command "fastboot flash recovery <filename>.img"
5) Take out your battery and wait again for 5 secs. Reboot phone by pressing volume up + power. You are now on your custom recovery free to install whatever you like

Thank you very much, this is what I needed and hopefully it'll help others. I had problems at #4 but I installed TWRP from fastboot and now I have my recovery. +1
