.510 has always had anti rollback.

The method of delivery makes no difference. Its not the app or software that is used to flash the aircraft that blocks it, it is the software that is on the drone. Using the smart controller, normal phone and Assistant2 etc will all net the same result, the delivery is the same, it cant just bypass it.

Unfortunately I dont have a solution in the near future
