Just relocked the bootloader last night and went back to stock ICS. Might even just stay with this for a while, as it works!!! Better than not getting text mesages, lagging etc that almost every single custom ROM suffers. Sick of tinkering with my phone, just want it to work like it should.

Requested the code last night via the website, around 9:30pm. Will see how long the response takes.

PS My phone will still be networked unlocked wont it? or will I have to do that again? Was unlocked when I bought it from eBay.

The network unlock is permanent,
the bootloader and network unlock are completely different things. You don't have to worry about it. It will stay unlocked :)

Guys, i have a little problem here.

Can't use the form on the site because when i type that code on the dialer to find out the product ID it does nothing, just disappears. So I emailed them using the template in the 1st post on this topic and they answered (pretty fast - 5 hours):

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.


So what can i do now? I replied telling them that i can't get the product ID but they haven't answered. It's been about 3-4 days now.

Excellent news, thanks george109 for confirming this. Still having 3G and WiFi issues on stock tho.... is this normal? I confirmed that the bootloader was locked again. Is it a specific 4.0.3 ICS software issue? Unlocking the bootloader will fix this???

I don't think so, What version are you on - if you go to settings > about phone, you will see a thing with a lot of numbers like U8815....B9** - Can you tell me what the B9** you have, and also you could always try downgrading if you have network issues...

Thanks

Ok, When you say network problems, can you be a little bit more specific, what actually happens? Can people call you?
Have you used any backup tools?

Well before I went back to stock ics text and calls were not coming through. They are now but the WiFi drops out altogether for no reason. 3g sometimes as well. Should I maybe clear all my Google settings. Could that be the issue?

Calls and text issue was random. Used back up tools before moving back to stock ICS.

@george109: Oke, I sent them another e-mail like you said. I hope they will give me the code.

Later edit: At last they sent me the code. Took them about 2 days.

Hi there

I urgently need the bootloader unlock code for my Huawei Ascend G300 U8815. Please note that I need the BOOTLOADER unlock code - not a network/SIM unlock code.

I have requested this several times before by email and using this web page but all requests have been ignored:

http://www.huaweidev...ethod=preUnlock

PLEASE PLEASE PLEASE send me the bootloader unlock code as soon as possible as I need it urgently and all previous requests for it have been ignored by Huawei!

My details are as follows:

Product serial number: ...
Product IMEI: ...
Product ID: ...

Regards

Got my code last night and unlocked the bootloader this morning.. after rebooting and connecting to Google account etc, I turned the phone off... It then gave me the pink bar and started a "Firmware Update" step 1/2...


Is this ok??? Have i just installed the OS again by holding down the down volume and power button... I just wanted to check that it was definately unlocked and this happened.


EDIT: WTF??It installed and now its formatting cache and data again..... rebooting.... another cycle.


Do i need to delete the folder on the SD card dload? I am going round in circles here. Apologies if I have missed a procedure...

No. The update updates the software, and the power and volume down puts the phone into fastboot mode, which is a mode that lets you change important things like the bootloader. When it is unlocked, its for security reasons. You can find out more here, http://android.stack...ader-wipe-phone
I would delete the dload folder, as you dont want to do an accidental force update and delete all of your data!

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
