I have one of those cheap 7" China jobs which I use as an eBook reader and not much more.
Suddenly it won't start, by which I mean that I see the "BIOS screen" with the green Android robot and the OS version, kernel version and SDK version, then it shows a black screen with the word "Android" forever.
There is no software installed apart from the eBook reader, so I don't mind doing a "hard reset".
How can I bring the tablet back to life?
