I was trying to push my luck a bit in hope it had the boot loader unlocked.

Let me have a think for a bit and a dig out around to see if i can come up with anything.

Have you tried getting in to standard recovery? (Volume button up and power button) Make sure she hold the volume button up and remove the battery for 10 seconds)

Just checking those update.app files (worldwide and serbia one) and the only difference is, that the serbia has one more file - updatecust.app file about 46MB... But the update.app s are SAME...
Sharkyo01 - did you force update / sdcard update with both files or only with that one (the main around 630MB large)? Did you ever tested only that worldwide one to update or recover G300?

Never touched the world wide B952 just the serbia one.

I would just try anything and everything. If you have a warranty take it back and deal with it that way if not go for it. Let us know any more. I am planning on writting a massive thread on all this stuff. Because I have a lot of data I have collect from this site and been milling it over.

Problems being that he can't access the phone. It does not boot up! I also don't think he has debugging enabled and unknown sources ticked.

OEM info hack could be used only when phone is running, connected to pc and via phone you have to ALLOW ROOT PERMISSIONS. That is why you get this ERROR on attached pic.
If there is no possibility to use any update.app (worldwide / serbia 952 or older GB one) and then you can try anything - what about to try that oficial tool for downgrading from ics to gb?

And there is one more possibility. My friend told me, that his SGS3 died, cannot boot it. He bought a HW tool called "JIG" which his SGS3 "resurected" - he was able to boot phone and after that he flashed it...

Here is link - sorry, only in CZ language, use Translator

Maybe it could help - not sure, working on Samsung Devices, maybe others could do that too... And maybe this could be the last thing to try before sending to warranty... Or send it now, before trying

I was right ... I have a few hours now let me have a dig around for you see if I can find anything.

Did you ever try that serbia rom?

http://www.huaweidev...softid=NDcwNjQ= - Serbia Rom

http://www.huaweidev...softid=NDcwMjk= - General Rom


Both are worth a shot in the long run!

I've tried both of them. I'm thinking that General Rom is that rom that destroyed phone (Was on G300 when he died)

Is your phone still under warranty? Depending where you are I know in the UK we have a 2 year warranty on ours!

Have you checked this post?

http://www.modaco.co...rade downgrade

Had problems with mine a few months ago, couldn't get any rom to work.

Also the rom I used to get it up and running. http://www.huaweidev...softid=NDY4ODE=

Transfer rom onto root of sd card and initiate update.

That would never work because your on B952 if you think you installed the general rom.

If you hold down power and volume up, what do you see?

Hello. I have an S4 now, and I hardly ever use MoDaCo now. 

Therefore you will receive no replies to any PMs

Please post in the forum instead. You will get more help there :)

:excl:A WARNING TO ALL G300 OWNERS! Please Read! (The Flash Memory Problem!) :excl:

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!

Spoiler

My Device:

Huawei Ascend G300 (U8815) - Sold!

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

(Ignore the links above (if there is one). It's a skimwords (advertising) link and nothing to do with me!)

The ROMS I have used:

Spoiler

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 I help you?

If I did, Please press the rep_up1.png button, in the bottom right hand corner of my posts.

(If not, Press it anyway!)

If I really helped you, you could also donate to me. Thanks!  :)

I have similar problem with my G300. I'm on Electra ROM but don't think that matters.

Turning phone on just displays splash screen.
Power on with Vol+ just displays splash screen.
Power on with Vol- just displays splash screen.
Power on with Vol+/Vol- goes to update but update never finishes.

The only way I've been able to get to phone to boot is to remove the battery then connect to USB power. Splash screen displays. I put battery mostly back in but just touch the battery off the spring contacts a few times ( effectively bouncing the battery off the contacts a few times ) The phone will reboot to splash screen usually but sometimes it reboots normally. I may have to try several times but eventually goes past the splash screen and reboots and I gain access to my phone again.

I've tried clearing everything possible once getting access again but this still happens when I try to reboot phone ( not always but most times ). But so far I've been able to re-gain access doing it this way...not ideal but only solution I've been able to come up with.....

Might be worth a try for anyone stuck on splash screen....let me know if it works for anyone.....
