I had recently updated to 4.21 Rogero and everything seemed to be going fine until games started loading slower than normal and the xmb seemed to really chug following a cold boot. So I attempted what I have successfully done before and tried to rebuild the database.
So I restarted in recovery and selected rebuild database and the PS3 froze at 0%. So I did a hard reset and when I rebooted, the hard drive data had been corrupted.
At this point, I tried formating via the PS3 which wouldn't work so I pulled the HDD, hooked it up to my computer and manually reformated via windows. Did all the checks, everything looks good with the hard drive now. > Threw it back into my PS3 and tried to run restore PS3 and was prompted to insert firmware 4.21 or greater. I first just tried reflashing 4.21 Rogero but got a 8002F2C5 error. I then went through a few other options and didn't have any success either. (421to355, 3.55Kmeaw, 3.55OFW, and 4.30Rogero)
Anyone have experience with this and have some insight into how I might be able to save my CFW? I am afraid to try and update to 4.31OFW.
Have you tried upgrading your console to 4.21? by chance, and yes you are going to need a flasher in order to downgrade no other way. But before doing so have you upgrade or are still stuck in the on the recovery menu wanting not to upgrade ??
