The bootloader unlock method from huaweig300.com is causing 3G reboots. To avoid them you have to relock your bootloader (http://www.modaco.co...d/#entry2128104), then unlock it using the unlock code from Huawei (http://www.modaco.com/topic/362821-tutorial-how-to-officially-unlock-the-bootloader-with-definitions-relock-guide-included/#entry2128112). Read the first post before you do anything.

 

Try getting the unlock code with DC Unlocker (dalyer's second link), if that fails, read the first post in the unlock thread for the e-mail. Make sure you put URGENT in the subject. I got it the second day.

 

After unlocking the bootloader, flash CWM (http://www.modaco.co...d/#entry2128120) or TWRP (http://www.modaco.com/topic/362821-tutorial-how-to-officially-unlock-the-bootloader-with-definitions-relock-guide-included/#entry2128130).

 

After all that you're good to flash ROMs :)

 

Good luck and don't worry, we were all newbies at first  :P

Thank you, but bootloader is already unlocked, I unlocked it before installing 4.0.4 - CM9

I followed complete procedure from  http://huaweig300.com

 

 

Is this not ok? Do I have to unlock it again?

 

Which method do I now use, from 2nd link = with DC unlocker? or from first link?

 

Please be patient with me, my android custom rom knowledge is very limited :(

 

Thank you.

 

Kind regards

 

 

 

 

As mentioned above - the HuaweiG300.com tutorial uses a hacked unlocked ICS bootloader and this can cause 3G reboots and maybe other instability. At the time that this tutorial was written there was no other way to do this but since then it is possible to unlock officially as per the other tutorial that I listed. (This is a slight problem here - some of the information is old and not up to date with later developments making certain procedures easier and safer) I would try the DC Unlocker approach first as it does not require the code from Huawei. But if it does not work (it doesn't work for everybody for some reason) then you need to get the code from Huawei (which can take some persistence!) to unlock officially. In both cases (DC Unlocker or tutorial) you need to revert to stock ICS B952 to unlock the bootloader. DON'T try this with a GB ROM installed or you will brick your device and it may be hassle to recover it. Read the unlocking tutorial carefully before doing anything. When making any changes or installing anything on your device make sure that you understand what you're doing first and don't do anything speculatively as there is always a chance of bricking or messing up.

 

Another reason I stuck with GB ROMs was because it meant that I could revert to the GB bootloader which is inherently unlocked and not bother with the slight hassle of reverting to stock ICS, getting the unlock code (although I did anyway), unlocking the bootloader officially etc. And as I said I found GB ROMs to be more stable and responsive than others anyway.

 

Hope this helps.

Revert back to stock B952, that will relock the bootloader. After that unlock it using the above link.

Ok, I read this:

http://www.modaco.co...d/#entry2128104

The post ends with info that I have to follow this:

http://www.modaco.co...d/#entry2128112

Do I really have to follow this unlocking procedure?

Thank you

Yes - unless 

 

(a) you want to stick with the unofficially unlocked ICS bootloader and run the risk of 3G reboots

(B) the DC Unlocker approach to unlocking works (you will still have to revert to stock - e.g. ICS B952 - to do this)

© you want to revert to the inherently unlocked GB bootloader and a GB ROM

 

You need to read the full unlocking tutorial - the links above are two individual posts in that tutorial thread.

 

Hope this helps.

You may have to try several times by email of the online form does not elicit a response.

Many people had to persist in order to get their bootloader unlock codes.

I already got a code :) but I'm not sure if it is correct. It has 16 numbers, no letters. 

Is this correct code?

 

Thank you.

I got answer that they sent me correct code and they sent me the same code again:

 

 

Dear Customer,

Thank you for contacting Huawei device.

Having caheck the code 1482161382369094 we provide is correct one.

Please kindly double check your unlock procedure.

Below please check the unlocking procedure for your reference:

Unlocking Procedure

Preparation

  1. Download the driver for your device from Huawei Device’s official website to a computer.
  2. Download the ADB toolkit from Google’s website and install it on the computer. For example, install the toolkit to D:\adb_tools-2.0. Ensure that the folder contains the fastboot.exe file.

Unlocking procedure

  1. Switch the device to fastboot mode.

Power off the device. (Note: Go to the settings menu and disable the fastboot function, or power off the device, remove the battery, and then wait for at least 2 seconds before reinstalling the battery.) For a mobile phone, press and hold the volume down and power keys simultaneously for at least 10 seconds (for a tablet, press and hold the volume up and power keys).

  1. Connect the device to the computer.

Connect the device to the computer using a USB cable. From the computer, open the command window, enter the directory where the ADB toolkit is installed, and check that the device is connected to the computer properly. To do so, enter fastboot devices, and press Enter, if a message such as 9e42530e fastboot is displayed, the connection is set up properly.

 

  1. Run the unlocking command.

In the computer’s command window, enter fastboot oem unlock password, for example, fastboot oem unlock 1234567812345678.

 

  1. Complete the device bootloader unlocking.

Enter the unlocking password. Your device then restarts. (If the password entered is correct, the device will be restored to its factory settings, after which the device restarts and enters standby mode. The device’s bootloader is unlocked. If the password entered is incorrect, a message is displayed and the device enters standby mode.)

  1. Check whether the unlocking succeeded.

Repeat steps 1 and 2. In the computer’s command window, enter fastboot  oem  get-bootinfo, the bootloader lock state of your device is displayed. Bootloader Lock State: LOCKED indicates that the bootloader is still locked. Re-perform the unlocking procedure and check that the password is correctly entered. Bootloader Lock State: UNLOCKED indicates that your device’s bootloader has been unlocked. You can then install a third-party firmware.

 

To lock the bootloader after unlocking it: 1. Restore the device’s software to the Huawei official version using a microSD card. 2. Switch the device to fastboot mode, and enter fastboot oem relock password (password is a 16-digit number) in the computer’s command window. 3. The device then restarts, and the bootloader lock state turns to Bootloader Lock State: UNLOCKED.

Once again thank you for contacting Huawei device.

Best Regards.

Huawei Device Customer Care Team.

 

First I will check again IMEI, SN, MAC.. and see if I maybe sent wrong data to huawei.

 

If I sent correct data, I realy do not know what to do?

 

Can I try DC unlocker procedure?

Double check the data that you send and make sure that it's 100% correct.

If it was then email them yet again asking for the code.

Just send a new email and don't bother referring to the previously sent code which does not work.

If they keep sending you the same code and it definitely does not work then you may have to just use the DC Unlocker approach.

If the free DC Unlocker method does not work then you will probably have to pay them the $1/€1 or whatever it costs to do the paid bootloader unlock.

Make sure that you are following the tutorial correctly and that you are on stock ICS (e.g. B952) when attempting to unlock.

If all else fails you could just revert to GB as I keep suggesting! :D

yes, I'm now on stock rom, bootloader is locked, I got same fastboot info as is mentioned in unlock, relock, revert to stock thread.....

 

I follow the procedure very strictly, step by step, when phone rebooted It display wrong code info (red text).

 

But I will check again all data, try again with this code if data is correct..., try dc unlocker....

 

You said above

 

you will probably have to pay them the $1/€1 or whatever it costs to do the paid bootloader unlock

 

pay to who, to huawei?

 

Kind regards

This is reallly frustrating.... :(

 

I have checked again (many times) all 3 codes, sn, mac, imei...and I sent correct codes to huawei.

 

I try again to unlock without success. In cmd it says okay, but on phone it says unlock failed, wrong code.

 

Then I use dc unlocker but also it did not work, unlock code is not displayed. I only get these data:

 

Model             
IMEI             
Wi-Fi MAC          
BlueTooth MAC     
SIM Lock status   

 

I will send again new email to huawei and hope that they send me different code.

 

How do I request bootloader unlock code from DC unlocker?

 

Thank you.

I don't know why the Huawei code will not work.

Was the IMEI ever modified on your phone?

 

I also don't know why the Huawei form for requesting the code doesn't work for you.

 

If the free DC Unlocker bootloader unlock is not working for you:

 

https://www.dc-unloc...unlock-tutorial

 

Then I think that you use the paid network unlock to also unlock the bootloader but I'm not 100% sure:

 

https://www.dc-unloc...nlock-procedure

 

Maybe check the DC Unlocker forums e.g.

 

https://www.dc-unloc...ead.php?t=18642

https://www.dc-unloc...ead.php?t=23234

 

Hope this helps.
