So many DJI drone errors

I turned on my DJI 3 Mini Pro and it has come up with so many errors. I did a factory reset but that hasn't worked.

I haven't used it since last summer and only turned it on to test fly it before i sell the drone but it won't take off due to all the errors.

I have tried uploading all the new software but still no luck. Also the drone isn't missing any parts. Is it worth getting the drone fixed or do you think it will cost too much to fix this many problem? It's a shame as I have hardly used it.

Has anyone else experienced the same/similar issues?
