You cannot do that with TB or other Dongle CFW's.
What this guy is saying is that after you downgrade, you install the QA flag app from Rebug, QA flag the console and then install whatever CFW you want via the recovery mode. If this is true, it would be awesome.
I wonder, if this turns out true, then does QA make the console ignore the lv1 checks, or does it really reset them? I think it is the former as it still shows 4.00 or higher in the menu.... Anyone attempting this: BACK UP YOUR BIOS before you do it!
Yes, anyone trying this do so at your own risk!
I believe it resets the syscon to whatever you downgrade to. Only reason i say that is because i have 2 HDD's for this console. 1 has Rogero v2 on it, the other 4.00 OFW. I can flash the nor to whichever firmware i want and just swap drives. BUT if I QA downgrade to 3.55 OFW, then flash back to 4.00 OFW the console bricks with a RLOD. I assume because the syscon is now looking for 3.55 fw instead of 4.00. If i then flash the nor back to 3.55 OFW, no more brick.
