Hi, after some days of trying to fix the issue by myself I now want to try it here
I am thankful for every helping hand!
Equipment:
- Phantom 3 Advanced V1.11
- GL300C Remote (should be V1.9.3 but current Version is unknown)
- Huawei P20 Pro - Android 10 / IPhone 7
- DJI Go 3.1.72
Problem:
No communication between Smartphone and Remote when connecting.
Smartphone gets voltage from Remote, but DJI Go App wont open after connecting Smartphone via USB. By opening DJI Go manually there is no Controller detected ("How to connect).
Drone still can be controlled by the Remote.
The error came originally by reconnecting the ribbon cable from the CON and MAIN Board.
My thoughts were that there is a problem with the USB Downlink Board, so I ordered a new USB Circuit Board. After swapping I have still the same issue.
What did I do before swapping?
1. Originally updated the Remote via DJI Go (because of update message)
2. Update was faulty, so the controller didnt come back in functionally Mode. Mobile device connection still worked, but drone was detected as Inspire 1. Downgrade/Update always result in an error. Tried it via emergeny Mode (C1+Shutter).
3. Did a Hardware reset by unplugging battery connection
4. Did a downgrade/Upgrade via DJI Go (down to 1.4.3, up to 1.9.3)
5. After that everything worked fine! All functions came back, Drone was detected as P3A and Transmission was there. Did a Update again and everything worked as designed.
6. The case wasn't screwed well, so I screwed it again and pulled the ribbon cable off in the process, as well from the CON Board, as from the Main Board
7. After screwing together again, the communication between Smartphone and Remote did not work anymore, but the mobile device still gets charged.
8. Reconnected everything again, reinstalled App, Softresetted Controller several times, tried different USB Cables
9. Tried to update (V.1.8.80) Controller again via USB Stick and Card Reader unsuccessfully (as far as I know only possible with DJI GO on the GL300C above V4.3)
11. Tried with and without USB debugging mode (Media) on Android
10. Bought a new USB Circuit Board and swapped it with the old one
That's the current status.
I'm really interested in fixing the error, but for the GL300C there is not much Information with this Problem.
Also I bought a TFID Board for reflashing the USB Circuit Board but now I know that the GL300C has it's Video Downlink function in the DaVinci Chip on the Main Board. So reflashing the USB Board wont be the solution I think?!
Any ideas or instructions to get my Controller back to function?
