I hope someone can help me but I've bought a used CIC Unit from eBay and everytime I load up ISTA/P to update the firmware it throws this error, I have updated many CIC Units and never had a problem but since updating ISTA to 3.66.0.200 I can't get past this part, I have no idea what the problem could be

My CIC Unit is now in Bootloader mode and can't flash it as this KMM 1027 error keeps coming up everytime

Hope somebody can help, I've been trying to figure it out for days

Any modules without the original vin?

Yeah, CIC Unit I put in has 0000000 as VIN but I can't flash it to update the VIN or access anything on the Unit cause it's in Bootloader mode

You will have to go WINKFP route I think? Or get older ISTAP
