If you are using the original ROM, why are you needing to remove the unlock patch?

Your IAP segment indicates that PUIS is enabled. Does your drive power up in standby?

The problem is that with the original ROM, everything shows red during the scan and gives an error, but with the unlocked ROM, I don’t have any issues.

Can you show us the label and both sides of the PCB?

The date code on the SDRAM is "034". That's week 34 of 2020.

The date code in the CAP appears to be "11192021", which is Nov 19, 2021. That's more than a year later.

There are no solder marks on the ROM, so that would suggest that the ROM has been hacked with a chip clip or via the terminal.

This is a disk with a configuration of the SD&D drives. Most likely, some changes were made to the CA while the ROM was unlocked. Everything on these disks is tied to each other. That's why this situation has arisen; everything needs to be restored to the way it was in the CA.

The first copy of the BOOTFW in the ROM has a date of 2021-03-22. The second copy has not been initialised.
