I have tried searching the history of the forum and found plenty of advice, mostly relevant to the 504. However I don't appear to get the expected result.
I have a 604 which shows Recovery (code 2) problem when switched on. If I switch on whilst holding the TV/LCD button, I get Recovery (code 1) error.
Regardless of which option I chose, for each recovery code, the tablet just restarts and goes to the same menu.
I've tried connecting to my PC via USB, but again no difference to menu.
Everyone else seems to get further than this, am I doing something wrong?
Its either the battery of the hard drive. Chose usb mode and connect it to the pc and see if the computer sees it.
