Samsung Galaxy Tab Won't Boot


Jan 4, 2011
Power on displays Samsung, Then keeps displaying Verizon Wireless.
I did Press and hold the “Volume Up” and “Power” buttons at the same time, when logo appears on the screen release the Power button.
When recovery screen appears use “Volume Up/Down” buttons to navigate and selected “reboot system” by pressing the “Home” button.

I tried "reboot system" but there was no change.
I see the "wipe data" choice, but what do the other choices mean: “apply update from sd card” and “wipe cache” ??
It was OK this morning until it froze, then...This is the first problem I have had.

Thanks, cb
