Downgrading with Hardware flasher

Dump

Connect your Hardware flashing device and make sure you are getting 100% correct, valid, verified dumps.

Checking console capability of running 3.55

Compare the values found in your dump with those in the table below

metldr+bootldr sizes

You can check metldr and bootldr sizes easily with HxD

• either after extracting flash with Flowrebuilder and opening seperate files
• or by looking in the unextracted Flash dump at the correct offset.

This table lists some common known values for your convenience as quick lookup:

Patch the dump & Reflash it to the console

You can use Hexeditor for patching (e.g. HxD).

NAND

Use NAND patches only on NAND consoles, not on NOR!

Target area	Patchfile	NAND Offset	Paste length	Remarks
ROS0	patch1 (7 MB)	0x0C0030	0x6FFFE0	CoreOS (prepatched 3.55)

NOR

Use NOR patches only on NOR consoles, not on NAND!

Reinstall firmware in Factory Service Mode

1. Use the PSGrade dongle to trigger Factory Service Mode (in the rightmost USB port).
2. Turn PS3 on, it will trigger Factory Service Mode and turn off the console.
3. After triggering Factory Service Mode, put the Lv2diag.self (see below) and prepatched firmware to install (named PS3UPDAT.PUP) in root of your USB Mass Storage Device and plug it in the PS3 (again, in the rightmost USB port).
4. Turn PS3 on, it will install the firmware you had put there (even though you have no screenoutput, you can see it is busy by looking at the activity led of the harddrive and of your USB Mass Storage Device).
5. PS3 will turn itself off after finishing the firmware installation.

See also Downgrading with PSgrade Dongle, which also contains alot of ready to use PSgrade HEX files for several dongles.

PUP to use

Rogero V2 or any firmware with prepatched lv1 (no syscon hash checks)

Different Factory Service Mode SELFs

NAND

For factory Service Mode install:

• if using the normal lv2diag : Use a NoBD patched PUP (e.g. Rogero NoBD PUP) (to prevent error 0x8002f057)
• if using the jaicrab NoBD lv2diag : Use the Rogero normal PUP (and redump flash after FSM to check both ROS)

NOR

Use the normal lv2diag and use the Rogero normal PUP

Only when having a console with a broken bluraydrive, you either:

• use the normal lv2diag : Use a NoBD patched PUP (e.g. Rogero NoBD PUP) (to prevent error 0x8002f057)
• use the jaicrab NoBD lv2diag : Use the Rogero normal PUP

Check the logfile

After installation of the firmware, take the created logfile in root of USB Mass Storage Device and look if it contains errors (pastie the log if you want to ask for help online on IRC)

Getting out of Factory Service Mode

If everything went fine without errors, you can take the console out of service mode and enjoy your downgraded console :)

1. Put the Lv2diag.self (see below) in root of your USB Mass Storage Device and plug it in the PS3 (again, in the rightmost USB port).
2. Turn PS3 on, it will trigger Factory Service Mode off and shutdown.
