I was running your latest 3.5 Final update actually colonel
I have done this with several phones several times during the whole aku 2.5 aku 3.3 period so I am baffled why this one went wrong. Obviously its got nothing to do with your rom.
What would running that exe do? Cuz the flash failed in the middle of flashing, I have tried hard resetting and soft resetting, it just comes back to the bootloader
