Hi could anyone help me out please. I have a Wondermedia WM8650 Android tablet Android version 2.2 Kernel Version 18.104.22.168- 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.
