Editing Factory Service Mode

[[File:PS3-factory-service-mode-for-downgrade.png|400px|thumb|right|Factory Service Mode]]
= What it is =
The Playstation 3 Console can enter a special "Service Mode". When it does so, the bottom right hand corner of the screen has a red translucent rectangle with the words "Playstation 3. Factory/Service Mode" inside of the rectangle.

= How to enter = 
To enter, it is needed setting Offset 0x48C07 on the [[SC_EEPROM|System Controller EEPROM]] to value: 0x00 or 0xFE, <br>
at least something beside 0xFF (inactive). This can usually be done via a special hardware logic dongle, or the Factory Service Mode Tool.

== Dongle == 
* When the PS3 is off<br>
* plugging a special "JIG" in the most right USB port (closest to the Blu-Ray Drive)<br>
* then pressing Eject immediately after pressing the Power button<br>

The PlayStation 3 is triggered into Service Mode when it boots up. 

(reference: [[Downgrading_with_PSgrade_Dongle#Getting_in_Factory.2FService_Mode_and_Downgrading| Getting in FSM with Dongle (2 Steps)]] )

== Factory Service Mode Tool == 
FactoryServiceMode Tool v0.2 (Only on modified Playstation System Software 3.55 and lower) allows you to enter Factory Service Mode without any Dongle and just through GameOS XMB.
 Requires 'LV1 mmap hvcall 114 fix'
 Requires 'LV2 peek and poke'


== Linux ==
 This requires graf chokolos modules and patches installed

'''1st step''' – Generating a challenge
----

# ps3dm_usb_dongle_auth /dev/ps3dmproxy gen_challenge

'''2nd step''' – Generating a valid response for a challenge
----

You need a dongle id.
Valid range for dongle IDs is 0×0000 – 0xffff. So choose one, doesn’t matter which one, but some are revoked !!!

# ps3dm_usb_dongle_auth /dev/ps3dmproxy gen_resp 0xBABE “here is a challenge like this 0xXX 0xXX … of size 20 bytes”

'''3rd step''' – Verifying response (Enabling “Product Mode”)
----

# ps3dm_usb_dongle_auth /dev/ps3dmproxy verify_resp 0xBABE
“here is the response from step 2 like this 0xXX 0xXX … of size 20 bytes”

== Rebug Toolbox ==
Select Option "Toggle Product Mode" under "Utilities" column.

= Features =
* Allows remarry-ing of the Blu-Ray drive
* Blu-Ray [[Fixing_DRL_and_CRL_Hashes|DRL CRL fixing]]
* Downgrading of System Software

== Level-1 Hypervisor ==
Different acting in Level-1 Hypervisor 

=== sysmgr_ss.fself ===
 partition related - Lets the PS3 function and turn on without a HDD inside, any actions 
requiring one will error out but not freeze (Tested on FAT NOR model CECHP01)

=== ss_server2.fself ===
 av settings related? - Gives the PS3 the ability to Video and Audio multi-output 
on all games and software (Games requiring an HDD will error out unless there is one in the drive)

=== ss_server1 ===
 trm manager usage related -> restart, backup+restore flash, flash address size, restore+backup srk/srh
 module loading related (user token, pkg/rvk verifier, update token (+seed)..) - Gives it a multitude 
of functions already listed here such as Downgrading/BD Remarry/CRL Files etc... but also lets the ps3 use ps2_netemu.self)

== Level-2 Kernel ==
It will allow to run an Application mounted via:
 dev_usb000/Lv2diag.self

== Game OS ==
Game OS Applications will be granted to access following Level-2 Kernel Syscalls:
 389 (0x185) sys_sm_set_fan_policy
 395 (0x18B) sys_sm_request_system_event_log
