Possible fix for Alpha 2s with bad lcd or touch
Dead touch screen or dead LCD. I picked up 6 Alpha 2 on Ebay with either dead touchscreens or dead LCD. All but one of them could connect to ADB or Livesuit flash, but stock and custom firmware didn't fix the issue.
I was messing around with images and I decided to give the Uberoid for the MK802 a shot. The MK802 is a Android mini device you connect to your TV that has an A10 Allwinner hardware platform. It does not have an LCD, accelerometer, or g-sensor. No Battery and runs off of the ac adapter or mini USB port.
I flashed the image to one with the dead LCD. I hooked it up to my TV and at first nothing. So I powered it off and booted connected to the tv and sure enough it came up into Uberoid ICS. I connected my wireless air mouse/keyboard combo and everything worked. Wifi was excellent, I tested Netflix and it worked better than anything I have put out. The best thing is without the LCD powered on the battery gets an easy 7+ hours streaming.
I tried it on the one with no touch and it worked just as well. The LCD does not appear to power up at all.
This is a great way to re-purpose a damaged or not working out side of warranty tablet and could work with just about any AllWinner A10 tablet. You end up with a dedicated HTPC with both ac and battery power.
WARNING - THERE IS NO GUARANTEE THIS WILL NOT BRICK YOUR TABLET. But it is technically already broken and the AllWinner platform is very hardy when flashing other AllWinner images.
