Happy to see that you have recovered your firmware and working with the first sended patched firmware that is based on iMac19,1 .. BUT you can have a full operating (or almost full ) with the Z390 Designare patched firmware with sended few bytes .. Like that, You don't have to use any SSDT ..except for cosmetic by renaming each sub-devices. You can also have XHC2 operating.** Elias64Fr's Modified Thunderbolt Firmware on my Designare Z390 Test Bench **
It was quite an eventful day, filled with as much volatility as the stock market has experienced in recent days. Today's goal was to determine whether it might be possible to flash the on-board Titan Ridge controller in a reliable and repeatable manner. Conclusion:
Meanwhile, because I bricked my Titan Ridge controller earlier in the day, I had to scramble to find a way to recover. After 2 hours of experimentation, I managed to flash @Elias64Fr's modified firmware to my Designare Test Bench using Raspberry Pi 4 and
- It remains very difficult to flash the on-board Titan Ridge controller.
- Perhaps @jb007 might find a workable procedure.
- Perhaps we'll find a way to extend the time window from 20 seconds to 45 seconds.

After adapting DSM2's SSDT for port RP05 and copying it to the CLOVER/ACPI/patched folder, I am happy to say that on-board Thunderbolt is now working to some degree. It's past 20:00 or 8pm so I'll conduct a battery of tests tomorrow, but for now I'll end with this:
