TB CFW > 3.55 OFW > Toggle QA > DEHASH using 3.55 KMEAW > 3.55 KMEAW(from dehash process) 4.21 Rogero v1.09

Success!

Followed instructions. Was previously on 4.21 Rogero. Tried to downgrade to update to v1.09. Now it's asking me to update to data version of 4.20 or later and telling me my data is not applicable. What do I do from here?

Try again from XMB. Worked for me (for me the system asked for 4.40 via recovery).

Edit:

While on Rogero CFW4.21, go to System Update from XMB and install the 4.25 downgrader CFW

Most likely you have a game inside, remove it

Not too worried, have 2 more consoles to dick around with and that CHECHH01 ones BD drive was f*cked. On the bright side I just updated my backwards compat fat ps3 from kmeaw to rogero's 4.21 v1.09 and its all gravy. Think I'm gonna stay away from this downgrading non-sense and just wait for the higher version fws from here on out.

It won't let me install QA. I can't do any homebrew from XMB. I didn't have a game inside. I checked even though I made sure I removed all games and extra USB devices before trying.

Sorry about that, I wrote fast without thinking (I edited my post after). just install via XMB

Then do I go recover mode and install 355 kmeaw clean again....
Then install 4.21 v9 straight over the 355 kmeaw I just did?

Or after TOGGLE_QA.PKG just recovery mode and install 4.21 v9 then?
