Help Help Me Please

[tjlumley]

Hi could anyone help me out please.

I have a Wondermedia WM8650 Android tablet
Android version 2.2
Kernel Version 2.6.32.9- default
Build Number Generic-eng 2.2 froyo ver 1.5.5-20110920.083830

It has a Green power button and red when on charge. It has a silver back and I believe it has a black audio port. It also has a home button.

I attempted to update the firmware to uberoid v12 and followed all steps I found on guides and followed on screen steps. But after being asked to remove sd card and reboot I now have a black screen I attempted to put a different version of uberoid v11 but still with the same results.

If anyone could help that would be great.

Thanks in advance.
