Yes, while trying to get the SW102 to work, I flashed the controller with 850C set as display. I did switch it back once I gave up on the SW102 and reinstalled the VLCD5.If I understand well you have flashed the controller with OSF for stock display (vlcd5)
That version will never work with an SW102 flashed bootloader.
For that you need the 860C controller version.
An torque range of 190 is more as reasonable, it means you have a very sensitive torquesensor.
Are you sure you have enabled calibration and estimated?
I described what I did to make the SW102 work, as it might've broken something unbeknownst to me.
The last settings used are as follows, and it provides no assist, except for walk-assist.
