TSDZ2 - can I use 850C with OSF?

[GrampaPete]

Helping a friend with an older TSDZ2 motor with 850C display who wants to switch to OSF. I have the .bin file for flashing the 860C - is there a file to flash the 850C or do we need to buy an 860C?

Thanks,

Pete

..... is there a file to flash the 850C ....
.

It is a bit of a gamble if you don't know what version of 850C you have.
A really old Bafang one could be possible to flash, but newer versions have other hardware or are specific made for Tsdz2.
These last versions of 850C aren't flashable.
See here too, for a 850C bootloader file

I'm thinking of replacing the MCU inside this dead 850c with the larger flash memory version (I tried flashing with latest firmware and it's bricked).


Any thoughts out there on whether this will work or not?


This is the most recent compiled for the 850c as we know Release Open source firmware TSDZ2-v20.1C.4-860C-update-1 · emmebrusa/TSDZ2-Smart-EBike-860C
