My problem is that I, like many more have tried to upgrade my k800 through seus only to find that it has installed a CID53 erom to my phone rendering it dead. Does anyone know how to fix this problem as I am clueless at the moment. Jdflasher is supposed to be able to do somthing but there are no real instructions and I dont know how it can help with a k800 when there is no CID53 firmware arround at the moment. Nice one SEUS.
