Ok, so I did it. What you need to do is the following:
1) Go here: http://www.modaco.co...rom-b952-to-gb/ and follow steps 2 and 3.
2) Now try to force update
3) Go here http://huaweig300.co...-baseband-root/ and root again
4) Install again 5irom and restore your IMEI
5) Follow the steps in this tutorial. It works 100%, just did it now.

Thanks :)
I will add this to the tutorial when my laptop is fixed, tomorrow...

Tutorial: How To (Officially) Unlock Your Bootloader! (The long way, but which definitely works)

Please, Do not use the HuaweiG300.com Tutorial on how to unlock your bootloader, it is better to unlock it officially with my tutorial!

Huawei Ascend G300 (U8815) - Sold!

The ROMS I have used:

Download Blink, a great app that controls the status LED on the G300!

Wait for 5 seconds and then click skip ad! Do not download anything in the ad window, that is not the app!

It's harder than you think... It could be anything from a random hexadecimal code to a code created from the serial number of the phone. It would be quite cool to make your own password generator though! :D

I used the mail template to get the unlock code, because I'm running a custom ROM :ph34r: , and they answered :
Dear Customer,
Thank you for contacting Huawei device.
Please apply the unlock code in our website http://www.huaweidev...d=toApplyUnlock .
Once again thank you for contacting Huawei device.
Best Regards.
Huawei Device Customer Care Team.

Link wich lead me to the current method wich requires the product ID... damn little filthy coward :angry2:.

I just want to know if I get back to a stock ROM, will I get the option to display this ID ? Do I have to relock my bootloader ?

I get back to a stock ROM and get my product ID, so I made the unlock demand by their website... but I'm still waiting for the code... It was a week ago. I think that I will go back to a direct mail but with the product ID in it and if they tell me to pass by their website, I will shut out that I'm still waiting it.

By the way, I want to say that I had "the pink bar stuck at 30%" problem with the force update, but I follow the little tuto from flor90 (the zero IMEI method) and it worked ! So thanks a lot !!!

They answered really quickly to my previous mail but they told me to use the form on the website. So answered back :

"I tried, multiple times in the past weeks, to obtain the code from the form in your website and I still waiting for it.
As you answered pretty quickly to my last mail, may I ask you to give it directly to me ?"

And that's worked ! Within the hour they gave me the unlock code.
So I really recomend to send a mail telling them that you are waiting for too long.

Thank you for this awesome guide. My phone originally had the Voda B960 firmware and I installed a custom ROM with the hacked bootloader. When following this guide I had trouble with the B952 update.app, I think this is because the partitions are different or something (I'm new to this Android dev stuff).

But anyway, instead of force installing update.app I installed these 2 using ClockworkMod Recovery:

http://www.modaco.co...15-voda-pt-rom/
http://www.modaco.co...stock-ics-roms/

Then carried on the tutorial as normal, and it seemed to do the job!

Another thing, when I restored my phone (which had a custom ROM installed), I couldn't boot. I also got round this by installing the custom ROM again as usual, and then restoring everything else except boot from my backup.

No guarantees if this will work for you, but it worked for me :).

Let me know if you found this useful or if I'm doing anything really stupid here, thanks.

If you go back to the stock ROM with a force update, you *might* have the option to get this, Personally, I am not sure as I am not on Stock. Sorry :(
However the force update will relock your bootloader

Greetings.
I've tried to "relock" my bootloader, because i'm having random reboots at my g300.
When i copied the Dload folder with UPDATE.APP and also dload.z01 files to both (internal and external SD Cards), turned off the phone and turned it on by pressing volume down and up and power button it shows me pink screen and won't unpack.
I was trying to use the spoiler what to do if the update fails, but there's one dead link : Now you have flashed the repack, you will have to go to the CWM home, then go to advanced > reboot recovery. Now wait until it reboots and then flash the relock bootloader zip by jsevi83.
And now i'm stuck.
Also sorry for my english language... it's not my national lang :)
Please help :)

@edit:
problem solved in the last post :)

You need to move the dload folder inside the archive, This means that you need to extract it and then copy it over. To the external SD card. Ill change the link, too :)
