Phantom 3 no signal after fimware

[brad2388]

I think i bricked my phantom3 pro by not updating in order.

I was on 1.1.9 so i download the newest whatever it is i cant remember now.

I got a long beep with a red led on the gimbal. Now it shows no signal on the live view. But i can fly and record just no live view. Ive tries to downgrade and all.

Anyone have any sugestions?0

Try installing it again by following these instructions exactly.

I have tried all firmware versions all the way back to 1.1.9 . When it fails i can look at the log file on the sd card and it tells me two devices cant be found.

That's a hardware issue. Check that your camera cables are not loose and/or that the gimbal ribbon cable is not damaged. Neither should be the case if you've never crashed your Phantom, dropped it, etc.

I've seen some people get around those device not found errors by repeatedly attempting to install the firmware. It sounds crazy, but sometimes it just starts working. Most people end up sending their Phantoms back to DJI for repair though.

Yea thats what i figured. It came in with 1.1.9 and i didnt know any better so i jump straight to 1.6.0040 and i read now that i broke it i should have went to 1.3.20 first. But ive tried it all

Is the serive bin file still in use? Or is there a new one?

You should have upgraded to 1.3.2 first before going to the latest. Try 1.3.2 again, might work.

Check the content of txt file on SD card, it might give you a clue. If nothing succeeds, contact DJI service for a free replacement.
