GL300C Version B no firmware

[kungfumike]

Hey guys. I have a P4A with a GL300C vB controller. I just fitted an HDMI module to it and now it says "disconnected". I go into the app and there is no live data or specs showing. When I go into the main page of the Go4 app and long press the 3 lines on the top right it says "No available firmware for this device". Is there a way to download directly to the controller without using the app or is there some other way? The app won't connect so I can't just check for available updates. Thanks

If you have PC you can get that from DJI Assistant through USB cable to remote. Should be a YouTube video how to. Did it work before adding the hdmi board? If so, something not connected.

I tried that and it won't pick up the controller. All worked fine before fitting the module and works fine when I refit the old one. Seems like the module itself needs programming.

Module new or used? I’ve installed a few on different models without changing anything, without problems.

Brand new, genuine part 54.

Maybe the module is bad.... especially if reverting back to the original hardware makes it work again.

That's what I'm thinking. I've put in a claim for refund.

Check to be sure you have good connections of the flat cables to the new board.

Yep. I've gone over it at least half a dozen times, using an illuminated desk magnifying stand to be 100% sure.

Gotta be a bad board. You didn’t stress the cables during the swap over?

Nope, works fine when I fit the old module.

Right,,,you did mention that. The chart does show that the controller IS compatible with the P4A. Gotta be the board.
Just a long shot idea,,, maybe delete and reinstall the DJI app.

Where did the new board come from?

Not sure. I bought it through DickSmith Online

Ok. I just looked again at the DJI chart and it does show the the “B” controller is NOT compatible. My mistake!

I hope you can find an answer to your problem.

I had an Advanced with the B controller and I put the HDMI module on it and it worked fine with my goggles. Not sure why you think it's not compatible?
