I know its a few threads about how to unbrick Advent Vega and how many threads is that many ideas how to do it.
I was running ViewCOMB 3.2 built 5.1 and everything was ok, but ive installed Rom Manager from Market, and tried other rom (wrong one ).
After reboot nothing is happening, i mean when i press power button for ok 10 sec and then short press again, screen is on black with backlight for about 1 sec and keep coming off.
Ive tried to turn into boot mode (2sec. back + 2 sec. power) about 1000 times already with power cable on and off, but nothing happening.
I have drivers installed on my laptop (had installed custom rom already).
I want to specify a few facts:
Is battery must be charged to full? or should start another try from flat?
If so, how to drain battery if tablet wont power up?
Is better to try with power cable on or off?
Some people saying about holding buttons for a 2 sec, other for 1 sec, what is right?
