This PlayStation 4 is currently on rare low firmware 9.00. The firmware can be updated to any higher version with a USB drive, but once updated it cannot go back to a lower version. It has been reset to factory settings and has not been connected to the internet since then.

Bought a faulty PS4 for 20€ (~21$), the seller said that it wasn't showing anything on the TV when turned on & didn't remember the firmware version. I managed to get it
Are you guaranteed to get a PS4 with firmware 5.05 or lower if you buy it now?
