• You don’t want to downgrade your PS3 on OFW 3.70 (you’ll loose all your data), but want to enjoy Homebrew and capabilities of Official Firmware 3.70 with one Console? Then this is the right tutorial for you. DiGiTaLAnGeL from Italy has managed to “fast-swap” between Custom Firmware (3.55) and Official Firmware (3.70) with the ProgSkeet Flasher and a second Harddrive.

    English Version for international blogs, greetz from Italy -Google Translate sucks- (and my english too… sorry )
    Today i’ll write a tutorial to “fast-swap” between CFW 3.55 and OFW 3.70, using 2 HDDs… at the end of the tutorial, you i’ll be able to swap between the firmware just flashing a dump on your PS3 using Progskeet. (instead of downgrading and loosing 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.(DOWNLOAD)
    • CFW 3.55 KMEAW “NO CHECK” by dospiedra.(DOWNLOAD)
    • Lv2Diag By Jaicrab. (DOWNLOAD)
    • Lv2Diag “FILE 2″ to go out of Service/Factory Mode. (DOWNLOAD)

    We need 2 HDD because the NOR flashes stores some parts of the current FW on the HDD… so we will need 2 HDDs, one is for 3.55, and one is 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.

    1. 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.
    2. DUMP your actual NOR and call it “original dump 3.70.bin”
    3. Now flash your “downgrade.bin” (edited with the personal data found in “original dump 3.70.bin”)
    4. Turn on your PS3 and be sure that the PS3 is asking you to press the PS button (downgrade.bin flashed correctly )
    5. Insert a 3.55 Downgrade dongle and enter factory/service mode.
    6. Copy Lv2Diag.self by Jaicrab and the 3.55 NO CHECK UPDATE renamed as “PS3UPDAT.PUP” in the root of your USB Stick.
    7. Plug in the USB Stick in the most-right USB port of your PS3 and wait for it to turn OFF.
    8. Leave the factory mode using the other Lv2Diag.self
    9. 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”.
    10. DUMP your actual NOR and call it “swap dump 3.55.bin”
    11. Unplug HDD B and Plug in HDD A.
    12. Turn on your PS3, plug in your USB Stick containing official 3.70 update and press start+select when asked.
    13. 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 OVER! You should have “swap dump 3.55.bin” and “swap dump 3.70.bin” … Now you just have to swap HDD and flash the corrispondent 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 CFW disable the Syscon checking at the startup… so it will not freeze or complain when the syscon 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!-

      So anyone know if this may be possible with the fat PS3's, and with a x3max usb dongle perhaps?

      This sounds like a sweet solution to keep your jailbreak and and now and then play legit games online. Seems like this came in just in time for BF3!

      i saw the progskeet downgrade and also the price believe me no mater!! BUT risk to brick you ps3?risk to lost your warranty?noob in soldering! well guys ill wait for a solution to the problem end i want to believe that is an easier way out there to downgrade your machine that is not realised yet for a reason... the only thing that i hope , is to find the keys of 3.70 and making a cfw and of course to enable al of as the qa flag...to save our 45-55 euros and all that risks of bricking our 245 euro machine...dont blame me for anything its just my opinion and i thing that this is also the opinion of many people out there..also dont blame me for my bad english i speak greek and im from cyprus...

      Shout out to DiGiTaLAnGeL!!

      That's major! Right now a SLIM PS3 is sexier than having a PHAT with backwards compatible and I have a PHAT!!

      Great breakthrough!!

      So, if i download something from psn store, i'll be able to play it on 3.55 too? I know that that is a stupid question, and this one too, but the dev_flash stays on the HDD or on another board on ps3?

      And ps3s "borned" with 3.56 can downgrade? because a friend of mine is crazy looking for a CFW or another method.

      no sorry,i dont buy proskeet!!!!
      so many months on 3.55 and they found how to downgrade from 3.70??
      what to do with 3.55???
      xbox scene is far far the best!!!!
      i have my ps3 sleeping!!!!
      and they coming with proskeet and saying its good news to downgrade from 3.70,and most of us dont even know soldering.....great news!!!
      anyway,its my opinion!!!!

      pampos and proskopos are most likely the same person, and obviously both of their opinions should be ignored. This is a solid product, and the progskeet is the first step in the line for people looking to remedy the lack of downgradability on their consoles. And BTW, the Xbox scene is nowhere near better than the PS3 scene. The devs are a bit more cohesive, I'll give them that, but there's not a lot of room left for development for newer consoles, the only ones that are really worth developing for (in my opinion) are JTAG consoles.

      Thanks Pirate! but i am on 3.55 CFW atm just wondering if this swap method would work cuz i want to pick up a few dlc for cod.. to me seems like it should it is just like a slim mostly with the NOR and all

      I really need to order more wire...I started soldering in wires to hook up my Teensy 2.0++, and I ran out of the super-thin stuff half way through. Radio Shack doesn't have anything to help...hardly a surprise, but I figured I would at least give them a chance. At least I know where to go if I want an overpriced cell phone or some low quality batteries.

      Hopefully by the time I get the spool of wire, someone will have made hex files for fast-swapping using a Teensy2.0++; I can't bring myself to buy a ProgSkeet, not when I already have multiple Teensy boards. Anyway...I have a certain fondness of the concept of using a JB device to do NOR flashing.

      look i said that is my opinion i dont even know if proskopos is girl or boy or where are he/her. the only think that i said when i see his/her reply is that i agree (so months from a new cfw that will solve a lot of problem to most people that stuck on 3.56+ and what?NOTHING only a downgrade hope with all that risks and spent of money that i said before just think about it!!! i dont blame anybody i like that people and the team that makes downgrade possible but ill wait for something solderless THATS ALL!!! ;p

      This particular tutorial needs some clarity, so I have a few questions:

      1. Is this "NO-CHECK" 3.55 version a KMEAW firmware, or just a stock 3.55 firmware? What I'm saying is, will this downgrade us to a CFW that allows us to still do homebrew, or is the quick swap not so quick as it would force us to downgrade and THEN install Kmeaw over the no-check 3.55

      2. Is it possible to do this without data loss on my 3.55 drive? In other words, can I remove the 3.55 drive, put in a clean drive for 3.70 and upgrade to the newest firmware, and then when downgrading BACK to 3.55, plug in the same old drivefrom my Kmeaw and reinstall the 3.55 no check without it formatting and erasing everything getting rid of my saves and homebrew?

      This needs to be updated, as these are just my questions, but I do greatly appreciate the work of the ProgSkeet team and those who wrote this tutorial. But for the people like myself who aren't afraid of soldering and TRULY want to jump on this ship, I need to know what I stand to lose. Because even if I back up all my data, I'd still have to either reactivate all my content or use that old school act.dat fix that was pumped out months ago.

      What if im starting at Kmeaw 3.55? Instead of at 3.70 ofw.
      I'm thinking i should install the kmeaw pup that has had checks patched.Take a 3.55 Nor dump.
      Swap the hdd, install 3.70. Take a 3.70 nor dump.
      I should be able to swap back and forth now too. Right?

      The Jtag is better to work with but the hardware is absolutely ****.. I have 3 Jtaged xboxes here with the red ring of death we had 11 at one stage but I binned the ones that couldn't be Jtaged. Im done with them if anybody wants one.. apparently there is a permanent fix if you re ball the cpu/gpu but to be honest Im sick to death of them and am loving the PS3.. The only thing you miss out on is DLC aand in my opinion the DEVS here are a lot better.. especially on this site.. PS3 over a 360 any day

      just realize... how come E3 Downgrader said about downgrading via USB with oneclick?!?! since the NOR flashes stores some parts of the current FW on the HDD, i'm sure swapping HDD is needed, just like this tuts, right?

      well, i didn't see they swapping their hdd in 'E3 downgrader promo' video.

      edited :
      from the last news, they also need 2 hdd's and a few soldering. so there's no doubt about this anymore.

      steps to do
      1 downgrade to 3.55 make a perfect 100% dump <--keep it safe
      pull out the hdd and write 3.55 on it

      2 put in other hdd
      upgrade to 4.0 when the console asks for the pup
      when done dump this too make sure it's a 100% dump

      now use these 2 dumps and hdd's to swap

      easy mode

      So in layman's terms, since the CFW 3.55 hard drive is well, a seperate drive from the OFW 4.00 swap one, any DLC I purchase on the OFW hard drive won't be useable on the CFW drive right?

      Correct, But you can use ReactPSN and if you have legally purchased any DLC you can still download Content onto your PC. There's PSN Links out there.

      Ok I have a FAT on 3.55 CFW and I have an extra hard drive. So if I put in the extra hard drive and format and install 4.00 What will happen when I put back the other drive on 3.55 CFW?
