@piansage
you did it with this method here on first page?
so you have flashed last software? F series or E series?
which software are you using for uplaod of FSCs?

Wondering, if the NBT of FSC Retrofit version is available? Read through all the pages and intel123 said it was done just testing...then no more follow ups. It's been out there in the wild for at least a couple of years....

I made some FSC codes with HU Tool 2.6 (I know it's ancient) and I believe I can import them using the old manual way using Esys. But would be nice to be able to just plug in the USB and be done with it. Thank you!

Hi everyone, 
I would like to activate CIC_Mid through Patch and fake FSC. 

It is known that the Patch from Intel123 only works with Professional units. However, you can find information on the forum that some guys have managed to activate CIC_Mid as well. Unfortunately, apart from the words themselves, I couldn't find anything else. Therefore, I wanted to take a closer look at the issue and try my hand at it. 

My findings at the moment are: 
1. Patch does not run via USB (What can be found on the web is confirmed)
2. Library error when trying to run Patch in Shell 
3. Swap of the Root certificate works until the CIC is restarted

It seems that there is also an rcert control mechanism in CIC_Mid, which replaces it with the original one if changes are detected. I also suspect that Patch doesn't work because the filenames in the CIC_Mid are different. The Cid_Mid are "CicMidNavRoot" and "CicMidNavSecond". I probably need to turn off control. Intel123 did this by changing two bytes in fs0. I'd like to do it here, but it begs the question, do I need to do a checksum correction when changing these bytes? If yes, how? I think that disabling the control would be enough to be able to replace the root certificate and upload the fake FSC to your VIN.

I can patch CIC MID to activate all certs but i must have unit to write patch manually.
