I just rooted my phone and everything went fine but whilst the back was still off (after having to remove the battery for 10/15 secs) the battery fell out, whilst the phone was still on and when I put the battery back in, the phone won't boot back up. Is there any hope, have I fused something or scrambled the battery's chips? I'm not sure what it could be? There is no charging light from either the laptop or mains charger. The only response I get it when I disconnect the phone or the battery from the laptop, the laptop recognises that something has been removed (makes the notification sound).

 

The phone worked perfectly before albeit a little slow, wish I never bothered tinkering now.  :unsure:

Welcome :)
Have you tried plugging the phone into the charger with the battery removed?

Thanks for the welcome.

 

I have tried every combination of battery in/out, laptop/mains charging. It's currently being left in the mains, hoping that it will just pop on :/ But the battery is not getting warm and neither is the phone. I just can't understand why removing the battery would kill both the battery and phone (does some sort or write out/ummount have to happen?)

However, pulling the battery and then plugging it in has bought my G300 back from the dead several times...

happens the same to me some weeks ago. it's a dead motherboard :(
i sended my phone to the warranty and came with a brand new board. they will not notice if you have an unlocked bootloader or root access since the motherboard is dead

The symptoms are:

-phone don´t turn on and don't give any signal of life
-when you connect it on a computer, windows detect an unknown device

I've just received a reply from Huawei who have told me to "give it a good charge for 8 hours" and if I still have an issue, to call their hotline for a detailed diagnostic and if required book a repair.

 

So does this cost me anything? I'm not sure if I'm still in warranty or not? I'll have to find some records and make sure.

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

Dazzozo always has a disclaimer, so it's your problem if you choose to flash one of his things. He isn't liable at all, and he can choose to leave it up if he wants.

Pulling the battery and leaving it out overnight can sometimes work miracles.
OTOH pulling the battery while the phone is running is a fairly sure way to scramble the rom,
and according to the literature a fairly sure way to fry flash memory chips.
I've always been surprised how well my G300 battery stayed in while I turned 
it over with the back off.
 
Might be time to put it all back together neatly in the box and try for a return.
If the memory chip is fried your typical servicedroid can't tell what caused it.

I probably shouldn't have done it but I have pulled  the battery on running phones (including the G300) many times without frying anything.

Me doing that has an even better effect! :P It makes the battery percentage go up by about 2-5%! :o  No Joke!

Do you know if it had Hynix or Samsung eMMC?
And did you run anything with the 3.4 kernel?
