It is huawei official ROM, it is in the form of UPDATE.APP and you can find it on official page of our G300 :)

Unlocking by this method solves the network dignal loss in JB roms?

[Guest jamie_w]

Hi Ive just received my boot loader unlock code. I'm running a jb rom, so could someone explain the procedure that I need to do to unlock the boot loader officially then reinstall a jb rom . thanks

[Guest denzele]

Flash stock B952 then unlock bootloader. If you don't understand go back a few pages in this post it's all in there.

[Guest jamie_w]

Ive downloaded the b952 worldwide release and installed. I downloaded the scripts onto my computer and tried running them, but it just hangs on waiting for device. What have I done wrong? I found out what I done wrong...Its vol DOWN and power button,

What os do you have on pc? No drivers in Bootloader mode imo.

[Guest jamie_w]

Whats the procedure for reinstalling a custom rom after officially unlocking the bootloader?

[Guest predragiPredrag]

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

You must install the UPDATE.APP with the OEM-INFO Hack Tool guide: http://www.modaco.com/topic/360716-oeminfo-hack-tool-v10-install-any-updateapp-20032013/

[Guest fraska]
