I was using my Nexus 7 this morning, when while in use, a black screen appeared with the blue-red-yellow-green cross. I’ve tried turning it off, but it always goes back to that screen, and I’ve held down ‘Power’ & ‘Volume Off’ to turn it off that way, but whenever I turn it back on, it only returns to that screen.
I’ve tried backing the files up to my laptop, but it can’t be recognised by the laptop. I don’t want to lose my data.
I know my serial number, and that it’s locked state is locked.
I’m happy enough to get the data off the Nexus, as that’s very important, and send it back or system reboot.
I’ve had it for less than a month, and to my knowledge it hasn’t updated to the 4.2.
hmmm, I’m afraid I don’t have any ideas myself. You could always try goving Google support a call, or the techie guys on the XDA Forum might be a better option.
I know people have got theirs going again with a “hard” reset but this will result in lost data. Perhaps once the computer recognises it again some file recovery software might work but that would surely be a last resort.
What data might you lose, if you are using cloud services then it might be saved out there somewhere. Perhaps too late now but I make sure everything I do is via Dropbox, Google Drive, Google Music, etc.
If you get it sorted please do let us know, or if anyone else reading this has any ideas?
