Actually, I can't test it as I don't have the product ID. I have the SN and IMEI from the last unlock that I did.

Great! The product IDs are all different! Time to start up fiddler and see how Huawei checks the ID!

 

Why do Huawei have to comment in Chinese? It makes life so much harder :(

 

I think this comment in their HTML sums up Huawei's products and software really well: 

 

  您好,本查询功能还处于测试阶段,如有问题,请您及时通过邮件说明,发送至[email protected],反馈给我们的支持人员,谢谢!

In Google Translate English this means: 

 

Hello, this inquiry is still in the testing phase, any questions, please timely instructions via e-mail, sent to [email protected], feedback to our support staff, thank you!

Yeah. Thanks for that. I've had a look and they are all different. I tried to get it to work by putting in NY details and other people's product IDs but that didn't work at all. I had a look with fiddler but everything is done on their server, so I can't hack manipulate :lol: it :(

If my full details (IMEI, S/N, product ID) that I used to get the code from Huawei by email would help you I can PM them to you on the basis that I assume that I can trust you with them! :D

 

PS - wasn't aware of Fiddler before - interesting tool - thanks. :)

That would be really useful thanks (I won't abuse them! What can you even do with an IMEI and Serial Number? Also fiddler is really good for abusing testing some sites :lol:

Hi, please could someone help.

 

I could not force the update so went through the alternative methods and eventually installed ICS repack as suggested.

I then installed the lock bootloader zip as suggested.

The part i'm stuck at is where the guide says 'next post'.

I cannot get the command prompt to open in a specific loacation as i'm using xp.

I've added the command to right-click menu using registry fix but it still won't do it.

I'm also confused by the part of the post that says:

"plug it back in to the PC and go into the folder, where you extracted it". Now you are there, press Shift and right click. You should see a menu with a few strange options. You need to Click "Open command window here"

Extracted what?

 

I am doing this with a view to updating my phone to ClockworkMod Recovery v6.0.4.5 so i can install the KK Ultra rom.

The main reason though is because i cannot use the camera as i keep getting the 'can't connect to camera' error.

Still getting it after installing ICS repack.

 

Forgot to add - when trying to do the update it stalled at around 30% and there was no text just a pink progress bar.

To open a command shell just press Windows key + R together and then type in cmd and hit enter.

You might have to cd to the required folder after that.

The "extracted" bit refers to extracting the update.app zip (or rar?) image that you downloaded in two parts.

You should read the tutorial again from start to finish to ensure that you understand it.

If not then don't do anything as you might mess things up.

And also check if you have Samsung or Hynix eMMC (there's a thread on this and how to do it).

If you have Hynix be careful what you flash - e.g. the CWM to which you refer may be based on the 3.4 Linux kernel and could hard brick a Hynix phone.

Hope this helps.

I have a problem with locked bootloader. I enter fastboot oem relock 1822820880921762. No. bootloader I got email from Huawei so it is good. Despite this, the phone shows an exclamation mark and the information about the fail code or a fail image of something. 
 
Does anyone have an idea what is wrong and how do I lock the bootloader? My SIM card slot is broken and I have to send the phone for repair.

 

 

If it says image signature verification failed or relocking failed, then you will need to do a force update. This is because of a non-stock Recovery and / or ROM. To fix this, you have to SPAM Force update (This is an ICS, B952 Update), You will need BOTH files, as I have made a split archive. (Due to mediafire storage limits :(). Now you will need to download them to the SAME FOLDER! Please Verify the file with this hash generator. The Hashes are:

CRC32: 49ef9ecb
SHA1: af20acf3d79249bbb3ce938d96b7a4e059bd1005
If these are wrong, then you need to download both things again (Sorry, its the only way to remove !) Now you need to mount USB storage (Do it in recovery, as some ROMS a copy the dload folder and then paste it in the root of the SD Card. Like this: Now turn off the phone, and hold the Volume UP AND DOWN buttons at the SAME TIME! Now you will see a screen with a progress bar saying "Unpacking". If you see a pink screen, Check the SD card, and the folder. The dload folder is missing or in the wrong place. Now you will need to wait until it is finished. The phone will reboot. Now complete the setup, and you are finished! :D

 

 

It's not working :/

Just flash force update. (under restoring original bootloader). That may relock it. I can't remember. If it doesn't Then try relock again.

Hi. I followed huaweig300.com to install custom roms on my device. So i guess i have bootloader unlocked the unofficial way. My phone sometimes loses signal. Could official boatloader fix it?

 

Also my phone was never locked to a certain operator. Do i still need unlock code from Huawei?
