So I've had a hacked PS3 for a few months. Started with 3.41 dongle and went to Kmeaw 3.55. I want to go back to stock now (for PSN mainly and not getting banned). I realize what this entails and that there is a possibility I might not be able to hack my PS3 again. Just wondering if there is a guide or something out there for this process. I'm assuming mainly just back up saves, re-format HDD via PS3, reflash 3.55 via recovery, and then update to latest OFW.
