My Haipad M708(Telechips 8803) runs Andriod 2.2 OK before. Sevaral days ago I found a 2.3 firmware and like to give it a try,unfortunately it was failed because CRC didn't match. I turned the device off when I saw the message(CRC check failure), and then it cannot turn on. I use FWDN V2.13. Please help! Thanks in advance!
