I checked the offer by groetech.
the controller should be from 2013 or later. mine is too old.
the reprogramming is done once by groetech. controller has to be shipped to them.
no software is to be purchased!
OK , there is poor chance to be successful.
The Controller works fine with the original front hub motor. I don't want to brick it.
I just ordered an KT Controller and join the world of freedom... :wink:
Thank for your contribution to flash the controller.
my model unfortunately has no wires for the programming connector. it seems to be a different model. i might remove the jelly to connect the 4 wires by hand. can you helf me to identify the correct code settings?
