Tablet Wont Start

[Mohammed Taz]

My tablet is not starting and not even going to recovery. I thought it is because of no charge but I am charging it for hours no effect. I pressed and hold all the buttons (power+vol up+ vol down). It was working a day ago, when I decided to charge it, it was 18%. I charged it to 87% and took it out. after few hours it is this state,
I have Galaxy Tab 7.7 with CM10 (4.2
I rooted it four months ago, no problems then.
I also have CWM recovery.

You need to hold Volume Down and the Power button for ~15 seconds.

Done that for more than 30 sec, no result. Any other useful suggestion?

I would have thought they'd use the home button in the combo, but maybe not. Try every possible combination (and don't count holding them all down as all the others).

Failing that, look up how to open it and disconnect and reconnect the battery.
