1- make sure you have the Blu-Ray drive attached or the QA Toggle package won't work.
2- Download the Rebug QA_Toggle package from here --->
Link ist nicht mehr aktiv.
3- Put the "toggle_qa.pkg" on USB and Install it on the PS3.(danach alle USB Geräte abstecken)
4- Run the "Rebug Toggle QA" from XMB, the screen will go Black and you will see HDD Led activity then if all went fine you will hear one Beep and the PS3 will Restart back to XMB.
5- If you want to make sure QA flag was set, go to "Network Settings" then apply the following key combo (all at the same time):
L1 + L2 + L3 (press left stick) + R1 + R2 + dpad_down
You should see Edy Viewer, Debug Settings, and Install Package Files if done correctly.
6- Now that you have QA flag set, Turn Off your PS3 and Turn it back on but into "Recovery Menu"
This Step is very important, it have to be from "Recovery Menu" and not a normal Update from XMB or the PS3 will Brick.
7- Now you must have any 3.55 OFW

8- Select the last option of the Recovery Menu --> System Update, then when prompted press and hold "Start+Select" for 5 seconds to start the update.
Once finished the PS3 will restart into XMB with the Syscon hashes reset back to 3.55 in both "ros0" and "ros1" and your PS3 is back like any original/non Downgraded PS3 that can use any CEX/DEX Fw without having to worry about disabling LV1 checks.
