After having no issue for the last month or so using CWM, tonight I booted into CWM as normal and then screen went blank.
I mean really blank, can't turn it off or on. Would a simple unplug of the battery and replug do the job or do I need to break out the JTAG setup? If JTAG is needed, does anyone know where that is on the board?
I did recently NVFlash from 1.1 to 1.2 so any advice on how to get this running again is invaluable as this tablet has info on it that I need to pull off. The only thing I can think of is if something in the recovery file got trashed and when it booted, it killed it.
Thanks in advance.
Open up the Gtablet by removing the rubber pads on the back and unscrewing the screws seen. Then, using an iPod pry tool or flat screwdriver lift the casing snaps apart. Start at a corner and work your way through.
Locate the area in Red.
Now Unplug the battery, left speaker, and capacitive touch cables. Then go through and use a piece of copper braid on your finger or a grounding pad and ground out those connectors as well as surrounding capacitors (notice the two caps in the red box). *THIS IS A CRITICAL STEP*
Before putting the back on the tablet, throw the Tablet into AVX mode by pressing power and volume down. This will be the first test as to whether or not it worked.
Yays! We did it and did not have to break out the BusPirate to do JTAG!
