Darn escape error, i have tried all the procedures recommended on this site with no luck. How does one troubleshoot the problem, I can not find flight records on the on board SD chip as they have been erased. Is the solution to buy 4 new motors and try installing them, and then buy a control board if this also fails.
DJI had been officially providing a new FW version to select users who say they saw ESC issues after the update to 1.11.20.
They were providing a tweaked version (
1.11.30) on a case by case basis as you can see here:
Firmware v1.11.30 for ESC error??
I don't know if they are still offering it directly to people as they were in the past and as far as I know they
never made it widely available. A few people here were a bit irate about it not being posted on the DJI website for everyone.
Some who were given the tweaked FW by DJI directly made it available via a download link on both
this forum and also the DJI forum. I archived a copy of
1.11.30 in case I ever needed it in the future, though I don't expect to ever update beyond the older FW versions I use currently. These second hand
1.11.30 FW files may be legit, but
since I didn't get them directly from DJI I wont be sharing them here. You can find links in a search of this forum (and others) to download a copy of
1.11.30. The most popular one here seems to be through MediaFire.
Of course, it's a risk to both use it from an unofficial source and also to use it if it will mask a more serious issue with your AC.
