hi, I've had my DJI Mavic mini for over 6 months, recently a code popped up code - 30210 it says to restarted the drone multiple time but it did not work I also refreshed and downgraded the software 2 times it too didn't work.I do not have access to any service centre as I live in India

I suspect the ESC has gone bad but I want to confirm the same but I'm not sure how.
I've linked the log and an image of the code can someone please check the log and tell me what is it that has gone wrong with the drone.
Thanks
Rishi.V.Reddy

well I live in India but I got the drone from the U.S  I contacted the DJI support they said I have to ship the drone there they will fix it and I have to get it shipped back to India and the cost of the shipping ( both ways) comes up to almost $180 (including customs duty) and then they said they won't be responsible it gets lost or damaged during shipping.
so I thought if u guys can tell me what's wrong ill order the parts and do it myself.

Rather than spend a fortune in shipping you can buy a lot of spare parts for cheap, a replacement ESC board can be had for as little as (around) 20 EUR or 23 USD.

Then you can try a DIY if you have some basic tools (you could still buy them if you don't and be ahead of the shipping price) or rely on some local electronics workshop doing the job on your behalf.

Actually disassembling and swapping parts on a Mavic Mini is rather easy. You can buy a set of spare parts and be almost certain to nail it down in the same try or have for example one plausible culprit swapped, like the ESC board and take your chance, knowing that you can get back to it at a later time with a different part or set of parts.
