I've been trying to flash my phone back to the Stock Sprint ROM. I've tried all three listed. Dumped, Signed, and Updated Signed. All three will start flashing at 1% and time out with an "Update Error." I've made multiple attempts from the tricolor screen afterwards and it's still the same issue. When I try one of the Custom ROMs, it works immediately. Anyone have ideas on why my phone doesn't like the stock roms?
