Update on my post, I tried another USB Stick with NTSC format and the system rebooted itself but I'm still getting the error when I try to upload the FSC

Anyone know the solution for this?

When you flashed the CIC you probably overwrote the new root certificates with the original ones which is why your FSCs now fail.

I had issues with entering the FSCs and the only solution was to FTP a blank generalPersistencyData_DiagnosticsSWTController file onto the CIC and then re-enter everything.

I think the procedure is mentioned earlier in the thread.
