Yeah, that's what was happening. Deleted the folder earlier and that was it sorted. Cheers. The 3g still knocks out the WiFi unless I turn off the 3g. Annoying

If you go home > settings > wifi > options button > advanced, then is avoid poor connections disabled? Also, is keep /disable wifi on sleep set to off?

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!

My Device:

Huawei Ascend G300 (U8815) - Sold!

Samsung Galaxy S4 (Black) - The LTE Version - GT-I9505

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!

Did not have the option to avoid poor connections. Just notify me of open networks. Turned the WiFi to always on. Will turn on 3g again and monitor. Thanks again George.

Hi there,

So I have been trying all morning to download the Force update but no luck at all. Can somebody re up the thing or upload it in some other provider like mega or so?

Greetings and thank you all in advance :P .

I thought you could but haven't tackled this (reverting to stock update.app in order to unlock the bootloader with the official unlock code) yet myself... :o

Actually - either will do. I downloaded the split zip in the original post and extracted the contents. The dload/update.app file that it contains has the MD5 checksum mentioned in the original post.

I then downloaded the Huawei B952, extracted it and checked the MD5 checksum of the dload/update.app and it is identical. This means that the files are identical so you can use either.

E.g. if you have trouble downloading the split zip from the original post or reassembling it (I couldn't do this with 7Zip and had to use WinRAR) then you can download from Huawei instead. It is a good idea to double check the MD5 checksum to ensure that the dload/update.app file is intact before attempting to do the forced update.

Hope this helps.

Yes, you have to use winrar, I will add that to the post :) Thanks.

No idea why 7Zip won't work. It should as far as I know. I have the latest version.
WinRAR worked but I also noticed that Windows Explorer also works if I choose the dload.zip (not dload.z01) file, right click and choose open with Explorer.
Anyway - I just wanted to check/confirm if the update.app in the original post was the same as the original Huawei B952 general update and it is. :)
I want to do the official bootloader unlock as soon as I get a chance and your tutorial is VERY helpful - thanks a lot. Hopefully I can make a small donation soon too...

7ZIP can sometimes act strangely, thats why I prefer WinRAR.
Also, If the hashes of the files are the same, they are exactly the same. I hope your unlock goes well, and any donation would be really appreciated. Thanks :)

Great guide thanks, I have followed this and unlocked bootloader but I have a question - if I flash a new ROM will this then flash a hacked bootloader or am I able to unlock like this then continue flashing custom ROMs?

You're Welcome :)
And no, Flashing custom ROMs will not replace the bootloader at all. Once you have unlocked, you can always check the bootloader by following ONLY this post: http://www.modaco.co...d/#entry2128103

Hey guys, I was running cm 10.1 before I unlocked the bootloader, followed everything and managed to do it but, after I restored my cm 10.1 installation the phone won't get passed the boot logo (Huawei Ascend) and no I did not restore the boot partition. What did I do wrong?

If you cannot boot, you could try going into CWM > mounts and storage > Format System > Yes, then mount USB storage, and then download CM10.1 again and then flash it like a normal zip, as it sounds like your /system partition did not restore properly. Hope this fixes your problem :)

Yeah, I did something similar, installed cm10.1 again and after that restored my backups (w/o boot). It worked fine and the bootloader is still unlocked. Thx for the help!
