Editing Talk:Dual Firmware

= Manual dualboot 3.55 & 3.70 with 2 flashdumps and 2 harddrives =
(temporary on talkpage for improving/editing the guide)

==Preparation in short==

===Getting original and downgrade to 3.55===
# Dump the flash and make sure it is useable for downgrade to 3.55
# Patch it for downgrade
# Reinstall the prepatched PUP (e.g. RogeroV2.pup)
# Redump the flash to make sure it contains the exact same CoreOS prepatched and keep this as '3.55-swap.bin' together with the used harddrive '3.55.HDD'.

===Getting latest===
# Update to the latest firmware you want to use (e.g. 3.7x) and reboot to make sure it works fine
# Dump the flash and keep this as '3.7x-swap.bin' together with used different harddrive '3.7x.HDD'.

==Swapping==
===When you want to boot to 3.55===
# Reflash '3.55-swap.bin' and insert harddrive '3.55.HDD'.

===When you want to boot to 3.7x===
# Reflash '3.7x-swap.bin' and insert harddrive '3.7x.HDD'.

[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!-

==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
