do you know how to format hdd sorry im not the best at this
1. Boot your ps3 into recovery mode
2. Select option "restore ps3 system"
This will format the hdd and wipe everything (games,saves,homebrew,etc)
When it is finished, you will be brought to a black screen, asking for your last syscall (last cfw installed)
3. Reinstall your cfw, or a downgrader and then a cfw of choice.
