Problems with phantom 4

So I recently took on the task of trying to fix a friend's dji phantom for him (he's not very good with tech), he might have trimmed a few bushed on accident with it and reported that it won't turn on and just beeps, he contacted support and they said that it just needed a firmware update. When I got it the first thing that I do is try to boot it up and see what happens, and sure enough it just beeps. The led on it puts on a nice light show for me (which isn't a good sign). It first flashes red a few times, then cycles through all the colors a few times, then flashes yellow before finally stopping and just keeps beeping.

All that I have tried with it so far is to update the firmware through Dji assistant 2. It was all up to date but I figured I should try to "refresh" it, so it all seems to go well until it goes up to the upload phase and it gets stuck at 28% then the drone power cycles and the update fails. After this happened to me a few times I tried the previous update, and I got the same result over and over again. I figured that the sd card may be full, I checked it on my pc and it had about 2gb free, which I assume is well enough for a firmware update. Then I tried to charge the battery for about an hour or so, and that didn't seem to help either.

So now I'm starting to this this may be a problem with something inside the drone, and as I'm not confident enough to open it up, or know if I even should incase there may be some warranties that would be voided.

Now I'm reaching out on the forums here to see if anyone can help? Maybe I can get some guidance on what steps I should take next? Thanks in advance

Nope doesn't help out, still just constantly beeps. It was hold 4 red lights and a quick google search said that it could be a critical error, not really much help there though. I'm really just trying to figure out what needs to happen with this thing. Not sure if it just needs sent in for repair or maybe it just an update or something simple that I'm missing
