Thaeber, could be they dont even support now rev i with boot code 0x90 
What I recon - to sell your motor and buy FC2.0.
Anyway, is strange that I see in 43V bin file boot code 0x72 - bafang is messing it quite good.
Maybe they have plans not to allow mix voltage. If you buy 43V motor, you would be able to flash only 43V firmwares.
