Basically, in addition to the older hardware downgrading methods. PS3Xploit is a software method of downgrading assuming your model are in certain model ranges.
The same exact model ranges that you need for hardware downgrading.
Use MinVerChk to see if your PS3 can be downgraded to 3.55 or under for CFW.
If you’re outside of those ranges (aka in newer Slims and Super Slims), you can perform PS3Xploit HAN on those models.
