So I'm running 1.00.0701 and I'm finding I can't get a stable connection via OTG using the modded 4.1.15, the video feed just comes in and out. It worked fine up to1.00.0600. No such problem with the official 4.1.22. Using DJI Assistant 2 I can see you that 3 FWs are currently available : 1.00.0900, 1.00.0800, 1.00.0701 so my question is, can you downgrade to 1.00.0600 using another method ? Thanks !
