Can't Flash any Rom or Unlock???

[arvinghost]

i have a verizon touch pro. i unlocked it then i flashed a couple custom roms then i ended up flashing back to the stock the i relocked using the verizon relocker.

NOW i can't flash any rom or unlock it again. it keeps stoping at 0% then giving me connection error.

i even tried flashing using SD card but it keeps saying Loading but never let me to the step saying press power to start
