Got a generic tablet and was stuck on Android Logo
Tablet has WM8880 chip and looks like SunnyCube V7 or Via V7
No manufacturer markings on inside or outside of case

Screen info: SeaStar
BOE7D35LED HQ
ALD B0017-01A0
130503 00035

Installed firmware:

VIA V7 WM8880 firmware_20130704 and
FirmwareInstall+中性1.0.0 for wm8880 Phone Tablet.rar and return to
VIA V7 WM8880 firmware_20130704

Now will boot but the touch screen does not work.
Displays home screen but can not select anything
Checked cables and seem to be OK

Any help will be appreciated

1st off, you should be able to use a USB mouse to connect/move around with...
Once you can get that far, see if you have a Factory reset ability, and start with that...

Hope that helps! :D

Thanks for the tip.
I believe the vol-up and power will also do the factory reset.

I did that and no change but was able to activate the USB debugging.

It seems the firmware I loaded to get the tablet to boot does not support the touch screen in this unit.
Since this is a generic tablet I do not have the original firmware or know where to look for it.
Only info I have is the tag that is on the touch screen itself.

Installed uberizer on PC but can not find proper windows driver for the WM8880-mid device.
Downloaded and installed universal adb drivers but that did not help.

Took the tablet apart again and found the following markings that may be helpful.

On small cable: TYF1012V6 20130424 QX

On large cable: BF0G070BH5002D 301E0412MLA
FPC7005002 3T-FGD 20100520

Main Board: TW_WM0701-1680_V20 20130524
WM07014G512M-1680-SL-JDFRY1306250122

Maybe someone who repairs these tablets or may have had the same problem and found a fix may recognize something and could give me some direction to find the proper FWC file.
