I have an A1CS 8" tablet running android and have a problem.when I switch on, it runs through the set up process but seems to hang on the android logo . I have a USB keyboard and can stop it only by doing ctrl-alt-del but then it just starts the same loop again. Ive tried running the battery right down hoping it would sort the issue when i charge ip again but that didnt work.Any ideas? I'm abroad at the start Of a 2 week holiday and it has all my books on so I'm really stuck... Thanks
