Give us more details like when did you notice signal lost etc. Reason could be something different. Give a snapshot of all the versions you see on DJI Go app.
Do you know RC version? Is your dji Go app is connected to RC thru a good cable?
I believe DJI has revised the various drivers now and thus reverting back to earlier version is not allowed. It's a major change.I know its been mentioned in a few of the other "FW 1.10" threads, but it concerns me that DJI has stated we can't downgrade from 1.10 once its installed.
Based on DJI's demonstrated past behavior with regards to FW, it worries me a bit when I think about what may be included in 1.10 but not mentioned in the release notes. If something unexpected happens, we may not be able to go back to 1.9.
On the other hand, it also makes me wonder if there is something they know about 1.9 that they are not sharing. They've demonstrated similar questionable behavior in the past when they left 1.5 on their main download page even when it was widely known that 1.5 was causing crashes and 1.6 had already been released to fix it.
So far indications are that 1.10 is stable, but for me the jury is still out. As always, just my humble opinion.
Thank you very much for your answer! The version of my RC is the GL300B. The cable is the original DJI. I tried another and it was worse. I have camera and gimbal response but I can't take off the aircraft.
