For all owners of PS3 consoles downgraded from 3.55+ using hardware flashers and Rogero_CFW_v3.x
To "Dehash the PS3" (Reset the syscon) and have the PS3 back to normal safer mode like any original ( non Downgraded ) PS3, here are the steps :
1- After completing the downgrade process and having Rogero CFW 3.x up and running, make sure you have the Blu-Ray drive attached or the QA Toggle package won't work.
2- Download the Rebug QA_Toggle package toggle_qa.pkg
3- Put the "toggle_qa.pkg" on USB and Install it on the PS3.
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.
Here is how to access it:
a. Turn off PlayStation 3.
b. Turn it on and keep Holding The power button down; The system will turn on and turn off once again.
c. Once the System has been shutdown, Turn it on again and keep Holding The power button down (you will hear 1 beep first, keep holding) until you hear 2 consecutive beeps
d. When you hear the 2 beeps take finger off power button.
e. You will be prompted to plug in your controller via usb and then hit the PS button
f. The Recovery menu will pop up.
g. Last Option #6 is what you must use "System Update"
Alternatively you can simply use CondorStrike's Updater package to enter Recovery Menu directly from XMB without going through the boot sequences. --> Condor Updater v2.0
7- Now you must have any 3.55 OFW or CFW with original (non Patched) LV1 in your "USB:\PS3\UPDATE\PS3UPDAT.PUP", here's a link to 3.55-Kmeaw --> kmeaw355.PUP
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.
