Have you tried putting it in DFU Mode and connecting to iTunes on a computer?

lol i dont know what a DFU is.... think i got it doing something...  resetting entire phone as if it was brand new... i am HOPEFULLY restoring from backup earlier today... so it says restore in progress... maybe it will work...
