HAve you try with a computer with Windows 10 installed and the ninebot flasher?
My educated guess is that the DRV 533 is restricting esdowng to flash DRV fw.

Even if with win10 and ninebot flasher you stilll cant write the DRV your best chance is with STLink, disassembling the head and solder etc.
Wile soldering, use flux to help solder the wires easily and do better work! Using flux do it on a ventilated area and keep from breathing the fumes! Their nasty.

THANKS!!!
Your guide worked for me, I had some error, but was solved.

Now I have problem again. If I connect the second battery, there is error 42. So ninebot still unusable for me, max speed 25 km/h, no enought power to enjoy the ride.

I hope this can be solved and its a last problem.

Thanks for any help.
