Turning it off can actually cause a brick, depending on what firmware you are on. If you downgrade and install a 3.55 CFW that doesn't have the checks removed, and you toggle qa flag off, you will brick.
Unless you were to install OFW 3.55 or lower, before you install CFW 3.55 with checks. Then is the console only truly dehashed.
If you don't, then Qa flag is only masking the checks. They are still lingering in the syscon chip.
A true dehash removes the checks from syscon. Which is accomplished by installing OFW 3.55 or lower, with qa flag toggled on.
I hope that makes sense. It made sense in my head before I said it. But it is fact.
Thanks for this, I was uncertain about the dehashing process on an already QA enabled ps3. I usually take extra steps by going back to ofw 3.55 and then jumping to a cfw. If it dehashes when downgrading to ofw that's perfect.
I don't have to ever worry about downgrade bricking...unless I do something stupid or power goes out lol
