1. VMware Fusion 12.2.1 2. ISTA-P Loader 6.1F 3. ISTA-P 3.71 4. K+DCAN USB Cable 5. CTEK MXS 5.0(FAILED, need at least 50A Power Supply) To upgrade the ECU/DME, BMW requires a power source of at least 50A, I had a 5Amp battery charger(NOT an appropriate power supply), This is why software upgrade failed.
