I've got the p7500 wifi model. I've not rooted it, and have had it for a while. I was syncing it with my computer the other day, and the power went out in the middle of it. Now, since that incident, my tab only boots to the point it shows the samsung galaxy tab screen, then goes no further. Powering off and on results in same problem. I'm unable to restart into download, but I can restart into recovery screen. I have no idea what to do, nothing works. I tried wiping/resetting to factory defaults in the recovery screen, no joy. I have utterly no idea what to do next.
