You can't delete the firmware on the system. If it was really that easy to do, the PS3 would have been a hackers paradise a long time ago. Only a few more days until the patch is supposed to be released. You can make it. Just go read a book, watch TV, or do something productive.
okay, is there anyone with an empty extra HDD? I'd like to try something.
what if you get it work with a lower HDD then you go to system settings-restore ps3 system. like we've found out that the ps3 will asks for the 4.45 even if you switch it to a different 1. now that the ps3 system is restored it should be on its 1th version. switch it back to the 1tb and see what is it asks for. anyone can do that for me?
The answer is back in the thread, you are going to have to read 364 pages to find it.
