I want to downgrade from rebug 4.21 to KMEAW 3.55 I did install the "qa_flag_extra.pkg" when I was still on KMEAW right before I began the update procedure I would now like to go back to KMEAW temporarily so I can replace the blueray drive controller board. The exact procedure I use is somewhat of a mystery to me.
Can I just do what was previously suggested by Shaitan in this topic (Downgrading from 4.21 rebug to 3.55.3 rebug?) when a person wanted to change from 4.21 rebug to 3.55.3 rebug or would the procedure be different?
and once I have finished what I'm doing and wish to switch back to rebug 4.21 do I need to install "qa_flag_extra.pkg" again then from the recovery menu install official 3.55 then rebug 4.21?
