You must downgrade from 3.55 to 3.41 before downgrading to another firmware.
1) Fully power down the PS3 Fat (toggle the power switch)
2) Restore power to the PS3 Fat
3) Format a USB drive with the Fat32 filesystem
4) Open Lv2diag_355.zip and copy the file from the File1 folder (Lv2diag.self) to the root of the USB drive
5) Copy PS3UPDAT.PUP from Downgrade.zip to the root of the USB drive
6) Insert your payload device with PSGrade into the USB port closest to the Blu-Ray drive. Power on the PS3.
7) The PS3 should start up in service mode. Power it down with a controller.

Remove your payload device, and insert the USB drive into the same port. Power on the PS3
9) The PS3 will downgrade, and then automatically turn itself off. Nothing will appear on your TV.
10) Power your PS3 back on, and you should still be in service mode. From here, you can now downgrade to earlier firmwares.
To return your PS3 to normal retail functions, shut down your PS3 using the controller. Then, repeat steps 3-4 using the Lv2diag.self from the File2 folder instead. Then, repeat step 8.
