Unlocking Bootloader oficially with the code of Huawei

[Guest alkalinorap]

I got my code, relocked my phone and then unlocked it the official way but did not get rid of the annoying restarts!! :( Anyone has got an idea please?

Hi, with the official Bootloader unlock, reboots are discarded because of the Bootloader.

If you have reboots at the moment, are probably due to the ROM.

which ROM are you on? Try changing that and use something like Slim, Stock+, Lightning

I am running Slim V12 on 2030 baseband. :mellow:

[Guest Hayder7]

The reboots happen only when the mobile data is on when I am away from wi fi. There is also a strange behaviour: sometimes the phone vibrates and freezes when I press the volume + button?? Any idea please? :unsure:

What ROM?

[Guest Hayder7]

Hi Kyan.. It is slim v12

[Guest Hayder7]

I figured out this: the random vibrations are actually due to a bugreport generater that is activated when the vol - and + buttons are pressed together. I am trying to fix it and report later...In regards to the reboots I downgraded my baseband to the GB one and testing..

[Guest smweb]

^ Change to Lightning / Stock+ and see... might be Kernel issue also

I'm using slim v12 with official bootloader unlock, no issue found.

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

In this case I don't need to backup IMEI?

I can simply install CM10.1 without messing up the IMEI or I need to root the original ROM and backup the IMEI first?

I used that instructions and didn't mess up my IMEI. As I understood IMEI messes up after changing basebands from GB to ICS.

I have question, I got unlock code and downloaded official B952

and now I should flash that original rom over stock+ and that will relock my bootloader.

So after I relocked bootloader I am on official 952 but I want to return to stock+, what do I do, I just follow these steps or do I have to do something

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

Do i have to send them any data regarding my phone (my IMEI code) in the email?

[Guest sharkyo01]

Yeah S/N IMEI Software version and baseband off the top of my head. There is a thread knocking around explaining all of it.

It work on B895 ?

[Guest dalyer]

Well if you have B895 then don't you have the GB bootloader which is inherently unlocked?

I'm pretty sure that you have to install stock ICS and its inherently locked bootloader to unlock the bootloader.

You should also look at this thread:

Hello, 
I did send request mounth ago, and repeted it two weeks ago, but still there is no response from huawei. I even send e-mail to huawei, and asked them about unlock code, but no response, at all.

[Guest dalyer]

You just have to keep trying. 

Lots of people had to try many times.

[Guest amkiller]

Huawei sent me the wrong code too (I think it was the network unlock code). Replied to them asking for it again and got this:

Er.. help? :D

 

DC Unlocker doesn't give me my unlock code either (it detects the phone but just won't show the code).

 

 

 

Edit: Emailed Huawei again and they provided me with another unlock code which worked :).

I used Unlockbootloader.exe and no problems, for now.

From where?

If it's from the "explained like you're 5" then you may start getting "3G" reboots with the hacked bootloader.

[Guest amkiller]

I was getting reboots every few hours with CM 10.2 (I don't have 3G enabled, or even a 3G sim) and assumed it was down to that method :/.
