I had a tough time finding all the info to make this possible. I found a lot of threads, in my many searches all over the net, of people saying in could not be done. But I did find a few that said it could be done. So with their help I finally figured it out. I wanted to make this guide in hopes to help some that may have the same problem I had, or just wanted to be able to use any CFW, instead of the one on the e3 site. 3.41 for example. I suggest if you are going to follow this guide, to take your time and read everything carefully a few times before starting. Here is some important information that you should read. I AM NOT RESPONSIBLE FOR ANY THING YOU DO TO YOUR CONSOLE. Things you will need 1. PS3 compatible with e3 flasher. Any nor chip model PS3. Except those that came with a higher firmware than 3.55 from the factory. 2. an e3 flasher 3. micro sd card (I recommend to use a 2gb or less Sandisc. Just a recommendation and others may work fine.) 4. usb downgrade dongle (any jailbreak jig/dongle should work, I use my psp on 5.50 Gen-D3 and PS3Jig app) 5. usb flash drive formatted to fat32 6. Download the Downgrade any file pack 7. Patience, common sense, and the ability to follow directions. Before starting make sure you have a nor chip ps3 that can be downgraded. And never downgrade to a firmware lower than what came on your PS3 when you bought it new. Check your PS3's minimum firmware You can check to see the lowest firmware by using the minimal downgrade check PUP file. Just rename to PSUPDAT.PUP and place in a folder named UPDATE, then place that in a folder named PS3, and put on the root of your flash drive. Put in in the PS3 and navigate to system update. Choose update from storage device. Don't worry it won't update your ps3. It will tell you what the lowest firmware your console can go. You can also check this chart for firmware and nor chip compatibility. Check here Chapter 1 Part 1 Install your e3 flasher correctly intsall I am going to assume everyone knows how to install there flasher. There are many guides on this already. If you do not know how to install your flasher correctly go here. Make sure to tape the clip down to your nor chip and where it connects to the e3 card. Some models have a transistor in the way of the clip. To solve this problem you need to shave off a little plastic from the clip, to allow it to fit flush to the motherboard. If you receive errors when trying to make your backup, most likely the clip does not have good contact with the chip. I also recommend to solder a wire from the SBE to the PAO Tri State point in case of brick. Although it is not necessary unless you brick. So better to do it while installing the first time. Part 2 Make some bios backups. Update flasher and backup bios 1. Take your micro sd card and format to fat32. 2. Put the e3 10-28 update.bin file onto the root of your sd card. (we use this to update your flasher, because it will allow you to flash multiple ps3's. Feel free to use a newer update, if you plan on leaving the flasher installed and dual booting.) take the sd card and insert into the slot on the flasher. 3. Set the switches on your e3 1 and 2 down and the rest up. Turn on the ps3. All 8 blue led lights light up and means your flasher has taken the update. Press the reset button. 4. Move the switches to 1 and 2 down, 3 up, 4,5, and 6 down. Press reset. 5. Press start and wait for the blue led light to light up in sequence. When all lights have lit and alternate flash the backup is done. 6. Take the sd card to your pc and check your dump with this guide(VERY IMPORTANT). Repeat steps 4 - 6, two more times. at least. It's good to have a lot of good bios backups in case of a brick. NOTE: The newer updates for e3 flasher make 3 bios backups at once. I suggest you still repeat steps 4-6 two more times and check them all. When it makes the 3 at once they will all be the same, so if one is bad the other 2 usually are to. CHAPTER 2 Part 1 Downgrade to Rogero v3.1 w/ 4.11 Spoof Downgrade Put the e3_downgrade.bin file on your sd card. Insert sd back into flasher. Set switches 1 - 5 down and 6 up. Press reset, then start. Wait for the blue lights again. When done lights alternate blink. Shut down PS3 from XMB. Power on PS3. You should get a screen that says "Plug in controller to USB and press PS button" DO NOT DO WHAT THE SCREEN SAYS! TURN OFF POWER BY SWITCH OR PULL POWER CABLE. Insert your downgrade dongle in the right USB port. Plug in power cable or switch back on. Press POWER then EJECT in that order within a split second. and wait for the PS3 to shut off by itself. Place the Lv2diag.self and Rogero_v3_with spoof from the step 1 folder onto a USB Flash drive and rename R_CFW_v3.1_PS3UPDAT.PUP to PS3UPDAT.PUP. Replace the downgrade dongle with the flash drive in the farthest right USB port. Turn on your PS3. Wait. In about 3-5 minutes your PS3 will shut off. Take the flash drive back to the computer and quick format to fat32. Place the Lv2diag.self from the step 2 folder onto the flash drive. Put the flash drive back into the farthest right port of the PS3, turn on and wait, in about 30 - 45 seconds it will shut down again. Take out the flash drive, then turn on your PS3. The first thing you will see is Rogero when your PS3 boots up. Now you need to repeat Chapter 1 Part 2 Make some bios backups. This is IMPORTANT in case you brick while installing other firmwares. If you would like to stay on Rogero v3.1 w/spoof, and have no reason to go to OFW or another CFW, you can stop here. But remember if you ever want to change your firmware, it must be a "no check" firmware. Or you will brick. Part 2 QA flag QA flag 1. Quick format your USB flash drive to fat32. 2. Place the toggle_qa.pkg file onto the root of your flash drive. 3. Put in your PS3. 4. Navigate to install packages and install the package. 5. Go to Toggle QA app on the XMB and click X. 6. You will here a beep and see a blackscreen, then it will return to the XMB. If it doesn't reboot and try again. Steps 7. + 8. are not necessary. I do step 7. just to make sure the QA flag worked. 7. Then navigate to Network settings and press L1,L2,L3,R1,R2, and down on the d-pad. Now more options will appear in your menu. 8. Navigate to Debug System Settings and enable it. (I did it without enabling this setting, but since e3 site says to do it in their guide, it doesnt' hurt.) Part 3 Downgrade to any OFW Find out how low your PS3 can go with the downgrade checker. DO NOT INSTALL A FIRMWARE LOWER THAN WHAT CAME NEW WITH YOUR PS3! Downgrade to any OFW 1. Enter recovery menu on your PS3. a. with the PS3 on press and hold power till the machine turns off. b. hold power button again til the PS3 turns on then off again. c. hold power again until it beeps 3 times. 2. Put the OFW3.41_PS3UPDAT.PUP (or you can use OFW3.55_PS3UPDATE.PUP, and skip steps 5.+6.) on your flash drive like this: root:PS3/UPDATE/PS3UPDAT.PUP [remember to rename to PS3UPDAT.PUP] 3. Insert into the right usb port of the PS3 and choose option 6. 4. Follow the on screen instructions. Now you will be on OFW 3.41. You can install a CFW 3.41 here if you like from recovery menu. and stay on that. 5. Replace the PUP file on your flash drive with OFW3.55_PS3UPDAT.PUP. [remember to rename to PS3UPDAT.PUP] 6. Put back into PS3 and navigate to system update and update from storage device. Follow the on screen instructions. You will now be on OFW 3.55 and can install any CFW with recovery menu. Just replace the PUP file with your choice of CFW with the one on your flash drive. Now you can install any CFW from the recovery menu. Here are some CFWs I have included in the downgrade any pack. But feel free to use whatever CFW you like. Just make sure to get the PUP file from a trusted source. CFW Rebug 3.55.2 Rebug 3.55.2 True Blue Edition, if you have a True Blue Dongle. Kmeaw 3.55 is basic and I have never had a problem out of it on my slim. Rebug 3.55.2 Other OS++ Rebug 3.41.3 Other OS++ You can substitute any OFW in Chapter 3-Part 3-step 2., as long as it is not lower than what your console came with new. You can even use OFW3.55_PS3UPDAT.PUP in Chapter 3-Part 3-step 2., and skip steps 5.+6. I updated to Rogero 3.1 which fixes the blue screen error with v3 on some models.
