Thread: How to Fix PS3 Corrupted Data Update Error from 3.41 to 3.55 CFW

    Dear montys1987, I'm tryin' to update from 4.46 OFW to 4.50 CFW, but whatever CFW I try to install it gives the same error, (The data is corrupted. 8002F957). So, can the above process still work out for me to update to the 4.50 CFW? Or should I try another method? if yes, which process? Help will be appreciated.

    you have to downgrade your ps3 from 4.46 ofw to 3.55 ofw, only then you can install any cfw on it step wise. 3000 and 4000 series ps3s are not downgradable.
