Hi everyone,
First, I apologize for my English.
I have a PS4 FAT that currently has firmware 11.50 installed.
Unfortunately, I don't know its history and don't know the previous firmware version. The system says it's been updated to 11.50. There are no older notifications.
I've dumped the NOR memory and SYSCON using Teensy. I'd like to revert the firmware.
PS4 NOR tools only informs about the version range to which we can restore.
The only information I'm missing is the firmware version, which is in the inactive NOR memory slot.
Is there any way to find this information? Or do I have to try several older firmware versions until I find the right one?
Best Regards,
Dawid
