Can someone please help me with CIC HU replacement coding. My 2012 F10 (528i) CIC Head Unit screen was going blank on some days and I thought it was the issue with dying hard disk. I upgraded to SSD and after 2 days the issue was back. I got a replacement CIC HU from a 2013 F10 (535i) and installed in the car (with my upgraded SSD). Sound, radio, navigation, alert sound did not work and I ended up coding with the help of SWTPatcher-V2. I had exported only the navigation FSC code did not export the FSC Code CERT. But anyhow, I was able to get some FSC codes from the patcher and with some errors coding was done. Now, the menus in iDrive are updated to my car and not showing the menu items that were not applicable for my car. Radio works, CD works, BT works, everything working except the navigation. I am not happy with what I have done, but at least my iDrive is not dead while I figure out a solution. I found many helpful discussion, however some of the additional discussion were through DM and hasn't lead me much further.
Based on my reading on multiple forums, best option could be virginize the CIC HU and then code for my car (I want to keep it as last option). I still have my old CIC HU and wondering if extracting all the FSC codes and FSC cert from the unit and coding with new would help. As I understand, the replacement HU is newer, there could be still problems. Hence, I got some questions to work with moving in the right direction. I got ISTA+, latest Esys, psdzdata full, ENET cable, charger with 40A boost and some knowledge navigating through these 2 apps.

- Does flashing the old CIC HU and then extracting FSC codes would help? I would be using those FSC codes from the latest version and coding the replacement.
- If 1 is not the best option, does flashing the replacement CIC HU help?
- Since, I only have ENET cable, ISTA doesn’t display application numbers (with hex) that need the fsc extract. Can anyone point me to a possible list or let me know if there is a way to know from Esys?
- If I have all the FSC codes and cert from the original CIC, do I still need to use SWTPatcher for coding? Do I need to extract root and sig certificates from old unit too?
- I saw a post about virginizing the donor CIC HU by deleting donor FSC codes and requiring Telnet /FTP session to delete SWT controller in CIC. Is there an article or tutorial that can help me understand this?
