Editing Talk:Dual Firmware

== Manual dualboot 3.55 & 3.70 with 2 flashdumps and 2 harddrives ==
=== Old Guide ===
[http://www.digitalangel.it/2011/08/tutorial-fast-swap-su-ps3-slim-cfw-3-55-3-70-con-2-hard-disk-e-progskeet/ original italian and english guide posted by digitalangel]

Today I will write a tutorial to “fast-swap” between CFW 3.55 and OFW 3.70, using 2 HDDs… at the end of the tutorial, you will be able to swap between the firmware just flashing a dump on your PS3 using Progskeet. (instead of downgrading and losing all data).

The first steps are not so easy, so take your time and go on, by the way, you must have some skill with Progskeet, and it must be 100% working on your console.

What we need:
* PS3 Slim running with FW 3.70
* 2 Hard Disks
* Progskeet installed and working on your PS3 Slim
* Downgrade.bin edited with your personal data (there are tons of tutorials for do this)
* 3.55 Downgrade Dongle to do the downgrade process.
* Sony OFW 3.70 UPDATE.([http://playstation-3.logic-sunrise.com/telechargement-331678-ofw-ps3-370.html DOWNLOAD])
* CFW 3.55 KMEAW “NO CHECK” by dospiedra.([http://www.multiupload.com/4S6NGO13H4 DOWNLOAD])
* Lv2Diag By Jaicrab. ([http://playstation-3.logic-sunrise.com/telechargement-225750-lv2diag-patche-par-jaicrab.html DOWNLOAD])
* Lv2Diag “FILE 2″ to go out of Service/Factory Mode. ([http://www.mediafire.com/?b07qrb96iz99ibb DOWNLOAD])

We need 2 harddrives because the firmware is partial on NOR (CoreOS) and the rest is on the harddrive. so we will need 2 HDDs, one for 3.55, and one for 3.70..

We will call those HDD “A” (for 3.70) and “B” (for 3.55) dont mix them up!

Starting with a PS3 Slim with OFW 3.70.

# Plug in HDD “B”, format and prepare it if it’s required by the PS3 and you should have your 3.70 up and running.
# DUMP your actual NOR and call it “original dump 3.70.bin”
# Now flash your “downgrade.bin” (edited with the personal data found in “original dump 3.70.bin”)
# Turn on your PS3 and be sure that the PS3 is asking you to press the PS button (downgrade.bin flashed correctly :D )
# Insert a 3.55 Downgrade dongle and enter factory/service mode.
# Copy Lv2Diag.self by Jaicrab and the 3.55 NO CHECK UPDATE renamed as “PS3UPDAT.PUP” in the root of your USB Stick.
# Plug in the USB Stick in the most-right USB port of your PS3 and wait for it to turn OFF.
# Leave the factory mode using the other Lv2Diag.self
# After the reboot, you need to configure and set up your system… now you have a fully working 3.55 CFW based on KMEAW “NO CHECK”.
# DUMP your actual NOR and call it “swap dump 3.55.bin”
# Unplug HDD B and Plug in HDD A.
# Turn on your PS3, plug in your USB Stick containing official 3.70 update and press start+select when asked.
# When the PS3 reboots, check that the system is fully working and DUMP your actual NOR and call it “swap dump 3.70.bin”.

NOW IT’S FINISHED! You should have “swap dump 3.55.bin” and “swap dump 3.70.bin” … Now you just have to swap HDD and flash the correspondening dump:
* HDD A = swap dump 3.70.bin
* HDD B = swap dump 3.55.bin

WARNING: Do not install other CFW than the “NO CHECK” one… because it’s used to make the “fast-swap” working… if you flash something different you will not be able to go between the 2 FWs. This patch disables the LV1 for checking the Syscon hashes at startup… so it will not freeze or complain when the syscon hashes says “3.70″ and your FW is 3.55 ;)

WARNING: In case you wanna update your console with a future “3.80″ or-so firmware. Do not update your console when you are running 3.55 firmware! You have to go to “swap dump 3.70.bin” and then update as usual (XMB or recovery)… -By the way, the downgrade is confirmed working only on 3.70… we haven’t tested it on other FWs, you could loose the possibility to go back to 3.55!-

<span style="color:red!important;">'''Editoral warning:''' The "NoCheck.pup" is known to cause trophy errors, use the [[Downgrading_with_NOR_flasher#Premade_CFW_Rogero_V2 | RogeroV2.pup]] instead or build one yourself with [[PS3MFW Builder]] and the [[Talk:Downgrading_with_NOR_flasher#Combined_TCL_V2 | TCL]] from the NOR downgrader talkpage.</span>





==Patches 3.41==

'''Once this patches are tested and confirmed to be safe, they will be commited to the MFW project'''

===Debug info patch tlc - patch_lv1debinfo===
'''Warning try these patches only if you have nor/nand flasher to recover'''
These patches allow the output of the debug printfs on startup, the main problem right now is that the buffer is only 0xFE0 bytes long so it gets overwritten. If anyone figures out how to solve this feel free to improve it

* http://pastie.org/private/a70bfqddpersnqf6sekuuw

* To see the debug console one should read 0xFEO bytes starting from these offsets

== E3 Fast Dual Boot- OFW 4.xx and CFW 4.xx ==
please do come crying in #ps3downgrade


'''Please Read'''

Thanks and credits
pu6pu6 - ps3hax.net, original brief tutorial
kman28 - ps3hax.net , original fast dual boot guide
everyone in this thread for testing and what not - http://www.ps3hax.net/showthread.php?t=44955
PSdevwiki-especially eussNL

What is needed:
1. If you brick or otherwise damage your PS3, no one but yourself is liable.
2. You will need an E3 flasher.
3. The tristate on the motherboard must be soldered to the SBE point on the e3 flasher with a cable
4. The track between points A and B must be scratched out and a cable soldered between points A and the SBCE point on the E3 flasher. [[Hardware_flashing#Pinout_Gallery | Diagrams]]
5. You must be in a position to install a 3.55 firmware.

'''CFW Setup'''
Plug in your CFW hard drive. Put switch 2 up on the E3, rest down.
Install Rogero 3.55 V7. Preferably via recovery menu. link
Install multiman 4.13 or later. Link
toggle qa-verify, link
Install 4.xx CFW via recovery mode links
Power on ps3 make sure 4.xx CFW is working
Put PS3 off 
Change E3 switches as follows:
---SW:FLASHFUN/CFW/BACKUP/MICROSD/OBFLASH---

Click start this will backup the E3 onboard NOR to the microSD

Bytereverse the backup using Flowrebuilder

Apply ONE of the following no-check patches depending on your 4.xx CFW:

4.21 CFW - link
4.30 CFW - link

Link to patchfile

Open win skeet select patcher then select the patch file and input dump.

Once again byte reverse the dump so it can be used with E3 Flasher. 

Put the patched and byte reversed dump on the sd card - rename to bkpe3.bin

Before turning ps3 on, set switch to:

---SW:FLASHFUN/CFW/PROG/MICROSD/OBFLASH---

Press start on e3 flasher
Power off ps3

Put only switch 2 up rest down, and turn on. If you receive an error just press the PS button on the controller. Make sure 4.xx CFW is working fine.

Turn ps3 off-unplug the power

'''OFW SETUP'''

PS3 is off
Take microSD out of E3
put in your OFW HDD
set switches to:
---SW:FLASHFUN/OFW/PROG/OBFLASH/PS3FLASH---

Turn PS3 on
Press start on E3
Once done turn off

Put all switches on e3 down

Boot, u will get an error. This is good. Follow prompts and install OFW 4.31

When you want to switch to OFW, put ps3 off-change switch to ofw, plug in OFW HDD, and turn on

When you want to switch to CFW put ps3 off-change switch to cfw, plug in CFW HDD, and turn on


== Software Talk ==

Software wise from GameOS it would be possible to switch OS Bank, booting into a different Lv0->Lv1->Lv2.<br>

Theory: <br>
To switch back it is required being the other Bank modified not being original firmware files for getting access to Lv2 Syscalls, specifically accessing EEPROM.<br>
Newer (patched) CoreOS theoretically '''could''' run older dev_flash version - to a certain degree.
