For the average gamer: Stick to a GoldHEN exploit on 9.00. You can play 99% of backups without the risk of a NAND brick. ps4 tool downgrade v100 download better
: The PS4 stores two firmware versions on its motherboard: one active and one inactive. Reverting involves forcing the console to switch back to the inactive slot.

For example, after release 6.72, the PS4 no longer allowed downgrading below certain versions. But before that, using tools like PS4Tool, rxTools, or others was possible. However, with hardware changes like the PS4 Pro and later models, the architecture changed, affecting modding possibilities. The PS4 Slim uses different ECDSA keys, which might require different tools.
