Rebug 4.21 to rebug 3.55.3 Downgrade Clarification Please
So I was on 3.55 kmeaw for the longest time and then decided to upgrade to Rebug 4.21. So I installed my FW in this order over kmeaw all from XMB:
3.33.3 rebug then QA flagged my PS3
Now if I want to go back to Rebug 3.55.3 all I need to do is flash it from XMB correct? Or do I need to get into recovery?
Then if I wanted to go back to Rebug 4.21 I could install it over the Rebug 3.55.3 from XMB correct?
Am I missing any steps here? Do I need to de-hash or whatever else I've seen some people have to do?
Thanks for the help!
