I'm interested in learning more about how CFW is made and its limits.
I was thinking about ways to safely get a PS3 on PSN (with me having no knowledge of how cfw works), and I wondered why we couldn't just tell Sony what they want to hear about the console when on PSN. I assume if this was...
I installed CFW to do some things and look around, and now I'd like to return the PS3 to OFW. Will this be enough to make the console 100% safe again for PSN? I have saves, and trophies I'd like to sync, so I want to avoid wiping the HDD.
