STRATEGIZER · 01-15-2011

!! DO NOT ATTEMPT THIS WITH SLIM MACHINES !!

!! I cannot be held responsible if you brick your PS3. Proceed at your own risk !!

!! You have been WARNED !!

This tutorial will downgrade your PS3 from 3.55 OFW/CFW to a Modded 3.41 (Which really is 3.56), Then downgrade your PS3 again from Modded 3.41 to 3.40, Then update your PS3 to original 3.41 (So that you will be able to update to 3.55 again when all the good stuff from 3.41 come's to 3.55).

When downgrading a 3.55 PS3 to 3.41, You must use a Modded 3.41 which the PS3 see's as 3.56. If you try to update this Modded 3.41 to say 3.55 in the future, It will give you a error meaning that your pretty much stuck there unless sony release's a update higher than 3.55. But this new update by sony may not allow you to downgrade or even worse, Disable modding (for awhile

).

So if you have downgraded from 3.55 straight to 3.41, Chance's are you have a Modded 3.41 which wont allow you to update unless its a FW higher than 3.55 & its recommended that you downgrade to a lower FW than Modded 3.41 so that you can update with a Offical 3.41 update that will allow you (for whatever reason) to update to 3.55 without error.

Things you will need are...
*Jail break device (Dev board) Or a PSDowngrader/Clone that can put your PS3 into service mode.
*PSGrade (Hex file's to put your PS3 into service mode. Hex files for all boards here.)
*Normal USB
*Downgrade File's 3.55-Modded 3.41
*Downgrade File's Modded 3.41-3.40
*Official 3.41 Update
-Optional
*Official 3.55 update

6) Once the PS3 has turned it self off, Power the ps3 back on, you should still be in service mode, check your FW version now to verify you have downgraded successfully. Then turn Off.
