(adsbygoogle = window.adsbygoogle || []).push({}); I was going to update to it from kmeaw, but it said the found update was 3.66 , it say that for anyone else?

If you have any discs inside your PS3, take them out first.

No joke. I would have never thought that would apply, thanks man

No worries

Just saying, I wouldn't do the 4.21 CFW just yet, check if your on a compatible model just incase of a brick, I would provide a link... But I don't think I had saved the link.

Turns out my ps3 isn't compatible I didn't even have qa flags on , AND I had no backup or flasher, still worked. Don't trust peoples posts who say they bricked

Bricking is possible but some don't get bricked its just a possiblity I'm waiting for an update to it for more features.
