Hiii,

I recently brought a broken P4 pro with the mind set of repairing it. It connects to the phone via the remote but says the aircraft is disconnected. I am confused. All the moter seems to move one by one followed by a beeping sound. There is also the red light blinking.

Video: daji.mp4

I also tried to reset its update through "dji Assistant 2 For Phantom" but it keeps failing. My controller is compatible with the pro.“DJI Phantom 4 pro Transmitter Remote Controller GL300F”.

It have been a dream of mine to have a dji ph4 and I really want this to fly once again. I also have brought a camera replacement.

Are you at all familiar with that model, the startup and linking procedures? If the camera needs replacement you're in for a quite a job internally. But not too difficult if you enjoy that sort of thing (I do). Hope you got it cheap, operational P4Ps are not very expensive these days. Remember, Youtube is your friend, use it. Good luck
 
That constant beeping is not a good sign, like all the p3 and p4 the motors will twitch once powered on as the ESC's are tested by the mainboard controller, also the shell is in a right mess which means its been crashed into something or fallen out of the sky, i would quit now as repairs may end up being more than the cost of buying a working one, especially the shell.

Just watched the video, as previously noted it's a mess. In that condition most would buy it for parts rather than repair. If everything worked it might be worth a complete new shell but it doesn't. Personally, I believe you're going to spend more on repairs than the cost of a working replacement. To give you an example, I can ship you a beautiful P4P with 300F remote + 1 battery for $500. Anyways, good luck on your project, PM me if interested.

If any boards need replacing, repair cost goes up fast. There's a good chance you can recover what you've spent by listing it 'as-is' 'for parts only'. Incl your video. There's always folks needing replacement parts and yours fits the bill as it's cheaper than buying individual parts.

No error codes plus that abnormal beeping and prop movement I think your motherboard is shot.
Try reflashing the firmware with drone-Hacks.com. If that doesn’t do, the cost to fix this thing will be way more than it’s worth. Sorry for your loss.

GUYSSSS I FIXED IT!!! There was a cable that had came lose. Now it works!!!

However, the camera is still very burly. One time there was black lines but after few restarts, the black lines were gone. The camera it self doesn't have any scratches so I am lost. I am thinking maybe the cables?
 
If the camera is blurry it usually means a lens has come loose inside the camera head. I have a lot of them if you want one.No charge except for shipping.
oh okay, I will take you on your offer then. May I get your email?

Thank you!!! Really!!!
