won't boot

[lcolonel]

After receiving "Database Storage space nearly full" msgs, and deleting emails, and still getting msgs, I stopped some apps--facebook, verizon backup service, swype, but all recognizable. Now it won't boot fully--hangs on the Verizon logo. Trying not to have to do a hard reboot. Soft reboot did nothing. Any suggestions about restoring my Tab? I deleted about 600 emails, and only have a handful of friends or contacts, no apps to speak of, a few kindle books. All pics are on the sd card. Thanks!
