MP - Can't upgrade off of 01.300.0400

[ether_rich]

Problem?

Tried many options to install any new firmware from 01.300.0400 but nothing works... Used Assistant 2 from mac(reinstalled multiple times), tried from Go4(reinstalled multiple times) via remote and directly via wifi and even DroneZbreak. Read many threads on different methods all which have failed. Any help would be appreciated.
