Has anyone on here had any luck full flashing a a40? The newer bata software is suppose to support it but i have had zero luck. I tried it on 2 separate tcms with zero luck. Keep getting the error code $054C Operating System is not present in file. Neither of the trans files are locked and reflash security is marked can be cal or full flashed. I even pulled the file off of a tcm and tried to full flash it with same results. I cleared all efi software and reloaded it. Also tried the newest bata.
