A few hours after installing the Baidu V33 ROM and installing all the apps from my previous ROM Lightning Rom,My Phone just unexpectedly turned off and pressing the power button doesn't do any good nor does putting it on the charger.

When i put it on the computer USB it said that a Unknown USB device had came up.


I am think that the battery fused or something similar to that through then i don't understand how the computer identified an USB port but a few minutes that Device disappeared.

So what should i do?


P.S I tried to remove the battery a few times but no luck :( :( :( :( :( :(

Have you tried plugging the phone in to the charger with NO Battery inserted? Give it 30 mins like this and see if anything changes.

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 :)

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

(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.

This is getting ridiculous it is the third or forth phone to have similar problems. How old was the phone and how did you unlock your bootloader?

If you are reading this, then this warning is for you. Every word you read of this useless fine print is another second of your life. Don't you have other things to do? Is your life so empty you can't honestly think of a better way to spend these moments? Or are you so impressed by authority that you give respect and credence to all who demand it? Do you read everything you're supposed to read? Do you think everything you're supposed to think? Buy what you're told you should want? Get out of your apartment. Meet a member of the opposite sex. Stop the excessive shopping and masturbation. Quit your job, start a fight, prove you're alive. If you don't claim your humanity, you will become a statistic. You have been warned. ~ Tyler

Motherboard has almost everything on it, it's rarely the board itself that dies,
there'll be one weak component that thru bad design forces them to change the whole board.

BTW I'm noticing a lot of failures from ppl leaving it on charge overnight.
Mine will charge from 6% to 98% in 2 hours. After seeing even Apple's finest iPhones
catching fire from overnight charging, I always avoid excess charging.

Yes, the phone is s'posed to stop charging when it gets to full battery voltage.
But if the charger is still plugged in you're vulnerable to power line spikes.
Disclaimer: I've got no right to talk on this subject because I've never used the charger from the Huawei box.
I mostly plug in to my computer's USB, or use an Apple iPod charger, or another Australian specced
dual socket charger I bought because it has a tapon mains socket.

Another problem some people don't realise is the excess internal temperature can be caused by
sitting the phone on clothes, or carpet, or even newspaper, while charging.

A few people have reported alleged spontaneous deaths of G300s. I wonder if any/all of them were overclocking and if this could be a contributory factor? With anecdotal reports and people doing wildly varying things with their devices it's a bit difficult to establish if there is any pattern here..
