Editing Downgrading with Hardware flasher

<div style="float:right">[[File:NAND-downgrading-steps.png|200px|thumb|left|NAND flasher downgrader steps]]<br />[[File:NOR-downgrading-steps.png|200px|thumb|left|NOR flasher downgrader steps]]<br />[[File:Downgrading-installation-steps.png|200px|thumb|left|Downgrading installation steps ]]</div>

== Dump ==
Connect your [[Hardware flashing]] device and '''[[Validating_flash_dumps|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 [[Downgrading_with_Hardware_flasher#metldr.2Bbootldr_sizes|'''metldr+bootldr sizes''']] table
	
If not having a dump, use the [[Talk:Playstation_Update_Package_(PUP)#Using_fake_upgrade_to_get_lowest_firmware_version_info|MinVer PUP method]]
	 
'''Note:'''
: The mention of minimal version praxis on several other wikipages is only a rough indication.
: The two most accurate ways are to look at the actual dump and the [[Talk:Playstation_Update_Package_(PUP)#Using_fake_upgrade_to_get_lowest_firmware_version_info|MinVer PUP method]] itself, instead of flying blind on [[SKU_Models#Retail_Models|SKU tables]] and [[SKU_Models#Datecode_.2F_Manufacturing_Date|datecodes]]
	 
=== metldr+bootldr sizes ===

==Reinstall firmware in Factory Service Mode==
<div style="float:right">
[[File:Eclipse-inserted-in-FAT-PS3-green-led-lit.png|200px|thumb|left|PSGrade/JIG - in rightmost USB Port - for triggering factory service mode]]<br />[[File:USBSTICK-content-for-factory-service-mode-downgrading.png|200px|thumb|left|USBSTICK - content for factory service mode - downgrading]]<br />[[File:Sandisk-Cruzer-4GB-nonU3-inserted-in-Fat-PS3.png|200px|thumb|left|USBSTICK - in rightmost USB Port - for installing in factory service mode]]</div>

For this step it is required to have the console fully assembled (connected PSU, coolingblock+fan, harddrive, wifi/bt board, blu-ray drive etc).

<ol>
<li>Use the PSGrade/JIG dongle to trigger Factory Service Mode
<ul>
<li>Remove power from the console (rear power switch or remove powercord)</li>
<li>Put PSGrade/JIG dongle in the rightmost USB port (closest to the Blu-Ray drive)</li>
<li>Power the console so it is in standby (rear power switch or attach powercord)</li>
<li>Press power button on front of the PS3 then immediately press eject within ~100ms</li>
<li>If powered on correctly your dongle will light up (usually green) and trigger Factory Service Mode. The PSGrade will then power off the console. If it boots into the XMB with a red FSM logo in the corner you are using an old PSGrade.</li>
</ul>
<li> Put the Lv2diag.self (see below) and a [[Downgrading with Hardware flasher#PUP_to_use|pre-patched firmware]] to install (named PS3UPDAT.PUP) in root of your USB Mass Storage Device and plug it in the PS3 (in the same port as the PSGrade).</li>
<li> Turn PS3 on and it will automatically install the firmware you had put there. You will not have anything on the screen, you can only tell it is installing by the flashing USB and PS3's HDD light</li>
<li> PS3 will turn itself off after finishing the firmware installation (If it flashes red the firmware did not install correctly).<br />A logfile should be present in root of the USB Mass Storage Device with no errors</li>
</ol>

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

=== PUP to use ===
{{RogeroFirmware}} or any firmware with prepatched lv1 (no syscon hash checks)

'''Note:''' if your end-goal is a 3.56+ MFW, then it is safer to downgrade ''first'' to 3.55. Upgrading in service mode is never recommended (only lower or same version).

=== 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)
* <span style="text-decoration: line-through; background-color:#FFDDDD;">if using the jaicrab NoBD lv2diag : Use the Rogero normal PUP -</span> see note below (and redump flash after FSM to check both ROS)

'''note:''' since V3 Rogero is only available as noBD, use that one with normal lv2diag.self

==== 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)
* <span style="text-decoration: line-through; background-color:#FFDDDD;">use the jaicrab NoBD lv2diag : Use the Rogero normal PUP -</span> see note below

'''note:''' since V3.7 Rogero is only available as noBD, use that one with normal lv2diag.self

=== Check the logfile ===
<div style="float:right">[[File:PS3-factory-service-mode-for-downgrade.png|200px|thumb|left|XMB red square notification - factory service mode ]]</div>

After installation of the firmware, take the created logfile in root of USB Mass Storage Device and look if it contains [[Error_Codes#0x8002f..._-_PUP_.2F_Update_errors|errors]] ([http://pastie.org/pastes/new pastie] the log if you want to ask for help online on IRC)


'''Tip:'''
:: You can boot console to XMB while still in FSM, if you want to be ''really'' sure it installed fine.

'''Remarks:'''
::*If you are using a component cable the image might be garbled.
::*If you are using HDMI, you don't have any screenoutput at all after the "press PS-button" message. (note: conflicting reports on HDMI working or not in FSM)

=== Getting out of Factory Service Mode ===
<div style="float:right">[[File:USBSTICK-content-for-exit-factory-service-mode.png|200px|thumb|left|USBSTICK - content for exit factory service mode ]]</div>

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

# 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).
# Turn PS3 on, it will trigger Factory Service Mode off and shutdown.

== Dehashing ==
{{Dehashing}}

=== QA dehashing ===
{{QA dehashing}}

=== reFSM dehashing ===
{{reFSM dehashing}}

==== Remarks ====
<!--// '''ReFSM''' way is strongly recommended over '''QA''' if you do NOT install a nonpatched firmware //-->
* FSM gets you a installer LOG (QA does not)
* FSM does not delete ACT.DAT ([[QA_Flagging#Act.dat_.28PSN_activation.29_gets_deleted|QA does]])
* FSM can be done without a BD drive with noBD patched firmware (QA needs the BD drive present)
* FSM can be done without seeing XMB or Recovery (QA needs Recovery and XMB for the QA-flagging package)

Both ways ''require'' installing nonpatched firmware to dehash syscon bank. QA-flag can be removed/reset (but it is better to keep it flagged) after succesfull dehash, without bricking.


  <domelec> dehash procedure: fsm install ofw
            after console turns off take out usb stick and look at log file, 
            if log is ok then reinsert usb stick and turn on console,
            ofw will then reinstall, after console turns off again 
            take out usb stick and check log, if ok then exit fsm 

  <eussNL> do double FSM OFW, then get out of service mode.
  <eussNL> check everything is working
  <eussNL> THEN and only THEN, you can install whatever you want, in recovery.
  <eussNL> there is no need for factory mode after dehashing complete
  <eussNL> in fact, if everything works on OFW 3.55 after dehashing, 
  <eussNL> you can install [https://web.archive.org/web/*/http://ps3devwiki.com/files/firmware/MFW-CEX/Downgrader/Rogero-V3.2/ Rogero V3.2] in recovery and [https://web.archive.org/web/*/http://ps3devwiki.com/files/flash/Tools/toggle-qa/ QA-extra] flag it  
  <eussNL> if OFW 3.55 works then you proven that you dehashed
  <eussNL> so after that you can install whatever MFW 3.55 you want

  <eussNL> If for some reason you cannot dehash because of BD or BT errors
           then you can use PS3MFW Builder and the broken Blueray / broken Bluetooth
           tasks. Do not select downgrader patches, or you will not dehash!

  <eussNL> BD error can be persistant if flasher is still attached, 
           see: http://www.ps3devwiki.com/wiki/Talk:Hardware_flashing#BD_drive_not_found_problem
  <eussNL> 3 options: 1. open R7/R8  /  2. remove flasher control lines / 3. remove all flasher wiring

  <playonlcd> i  think you can update on wiki "dehashing with jaicrab is not recommended
              and will not dehash as needed and thus semibrick by syscon hash panic
