Changing to another CFW distribution can be a problem since not all CFW support the latest updates, this guide will help you installing any other CFW version on your PS3 or simply go back to 3.55 where it all started.

!!! – Only continue if your QA-Flag is enabled – !!!
Please whenever you use this guide successfully, please post your downgraded start and end firmware in a comment below, this will help others confirm their version has been successfully downgraded before:
Ferrox 4.66 -> Ferrox 4.65 – no need to download & install QA-Flag, build in with Ferrox CFW
