Excellent, thank you for explaining. I think this may have been my issue last night then. I though QA had to be OFF to be able to downgrade, as I say, because I thought it stood for "Quality Assurance". So I turned it OFF last night and then tried to downgrade!
I'm guessing then that it DOES stand for Quality Assurance, but it's from a game programmers perspective, to make sure their games work on all firmware versions, therefore checking the quality of their work.
Is this not all written down someplace so that someone like me can read about it rather than bugging you nice folks at every turn?
I just found some information here:
https://www.psdevwiki.com/ps3/QA_Flagging
I'm a bit concerned with what I want to do now after reading the following:
QA Downgrading[edit | edit source]
Crossreference: gitbrew.org PS3
owngrade
Notes[edit | edit source]
These tools COULD format your ps3. (which means Any and ALL psn / downloaded data could be erased)
note: several people noted that they did not suffer from dataloss even after several downgrades, but its good measure to backup before downgrading (esp. ACT.DAT which DO get erased)
Known Issues with QA flag / QA downgrades[edit | edit source]
act.dat (PSN activation) gets deleted[edit | edit source]
Make sure you backup the file before enabling QA-extra flag and downgrade. There have been reports of ACT.DAT ("home/000000XX/exdata/act.dat") get's deleted. So make sure to backup that entire folder before flagging/downgrading.
What does all this mean? What should I backup, and where would it have to go back once i'm done?
I'm not logged in with an online account on this machine. It's on the internet, but only to use PS3Toolset and clock synching and downloading updates for games etc.
Sony don't know about me owning this machine. It's not on my activation list, so if in the future I wanted it to be (like if i'm selling it on after putting it back to STOCK or whatever), can someone still use this machine normally after I've been messing with it even if I've not done the advised above? I need to have a walkthrough if I'm needing to do this.
