1. Boot your ps3 into recovery mode
2. Try option "restore ps3 system"
This will reformat the hdd and wipe everything (games,saves,homebrew,etc)
When it is finished, it will ask you for your last syscall (last cfw installed)
3. Reinstall your cfw
If that doesn't work, and other recovery mode options lead to freeze, I would assume your hdd is damaged and will need to be replaced.
