Replaced CCC with CIC on a 05 E91, everything powered up, sound working. I then tried to change VO to #0910 and add $6VA with NCS expert, I successfully used FA_WRITE on CAS module, but cannot write to FRM as I get an error when trying to write. (something about ECU, forgot to take pic)

I noticed after changing VO to #0910 there is only NFRM available to write to, no FRM (I have FRM1, FRM2 and 3 show as NFRM on NCS). Could there be some mismatch since it tries to write to NFRM when my module is FRM?

I can read the FRM without issues. Is it even really necessary to change VO on both CAS and FRM?

Use nfrm to do the writes.

I tried since there was only NFRM to choose from when selecting the module but I get an error similar to this: (just with FA_WRITE)

I was using expertenmodus profile, also tried revtor's.

Try using build date of #0909. You also shouldn't need to write to NFRM. Writing to CAS is sufficient enough to code CIC retrofit
