PS3 CFW Guides: Unban PS3 flashing new IDPS [SOFTWARE ONLY]

Disclaimer!! I will not be held responsible for your deck if it becomes a paperweight, I have noticed that some are just skimming through this guide and NOT reading it thoroughly. If done properly there is no risk. But after some of the comments and PM's I have gotten it is becoming more and more apparent that a lot of users simply are not reading and want this more less done for them when it is here in an easy to read format. It should also be noted for Rebug users that one should have all debug style option removed prior to trying this. Bascily you need to be in the mode that spoofs 4.41 and has no DEX/Debug option in the settings category. Use Rebug toolbox and set "System Mode" to NORMAL and "Debug Menu Type" to CEX QA before attempting this guide to ensure there is no chance of making a brick though it shouldn't. This makes Rebug about as close to a standard CEX CFW as possible.


So I am writing this as there isn't a real clear cut guide out there on just exactly how to do this from start to finish as you need more then just the app and a new IDPS to change your IDPS instead of having to run apps every time to use your new IDPS. This is a work in progress as I am trying to really document each step to make it as easy as possible, So please check back as I will be updating this throughout the day.

Requirements:

Cygwin (to install and setup openssl)
IDPS Changer v1.3
Multiman
Rebug Toolbox
A new unbanned IDPS (Ps3 system ids)
eEID Root Key (obtained on firmware 3.55 only, most have this before upgrading otherwise you must downgrade in order to change your IDPS
eEID Root Key Dumper Only for 3.55 CFW and only needed if you do not have your eEID Root Key
Tools to compare hashes, I use CLRMame Pro but there are many apps out there I am sure you probably already have one installed



1~ First thing we need to do is to get a good valid dump of your flash. So for this I myself use Rebug Toolbox. I made a total of four dumps with the toolbox then transferred them all to my PC. From here I ran a hash check to ensure the integrity of the files were all good. Using CLRMame simply fire up the app and choose "dir2dat" and point it to the folder where you moved your flash dumps. Then simply open the dat with notepad to see if all the numbers match for all the dumps as they should provided you don't have any bad blocks or just a bad dump. Once you are sure they are all the same and have a matching set choose one to work with and keep the others backed up for another time.

2~ Second step is running the cygwin setup.exe from above and then allow it to download the needed files and install. For the sake of this guide Once you run setup.exe have it add the files to c:\cygwin. Then you need to install openssl in order to use IDPS Changer properly. Double click setup.exe again and in the search box type "openssl" on the "Select Packages" step, expanding "Net" option, and clicking the "Next" button. Use the image below as a reference.

Again just set the files to download in the c:\cygwin folder to ensure all the needed .dll files are there for openssl to work properly or the app will crash every time.

3~ Now grab your NOR/NAND dump and rename the file to "dump.bin" also grab your eEID Root Key rename to eid_root_key.bin. Once this is done again place the files in c:\cygwin. If you don't have your root key you will have to downgrade back to 3.55 first. There are numerous guides right here in these very forums that have documented this process very thoroughly and there is no sense beating a dead horse. Google is your friend folks.

4~ Extract the IDPS Changer into the c:\cygwin, it will have one .dll file and the exe for the application. Once you have all the files installed and moved into c:\cygwin it is time to make a few compatibility changes. I am using Windows 7 x64 and this works every time I have unbanned friends systems. First right click on openssl.exe and enable XP SP2 compatibility on openssl.exe, then right click on both openssl.exe and IDPS Changer.exe, then enable admin access to these files.

5~ Now we run the app, so double click IDPS Changer.exe and it will ask you for your new IDPS if it detects the root key and a valid flash dump. If not please recheck and make sure your files are named properly. After this it will ask if you want to change your MAC address. You can easily make one by simply going to this site and clicking "create MAC Address. In the drop down box choose the bottom one that only gives letters and numbers or you will have to remove them for IDPS to recognize the new MAC. Press enter and wait....

6~ After you have done this it will make a new file called "dump_patched.bin" in the c:\cygwin folder. We need to rename this file for Multiman to recognize it as a valid flash or it will not allow flashing.

Nor model = CEX-FLASH.FULL.EID0.NORBIN

Nand model = CEX-FLASH.FULL.EID0.NANDBIN

Once you have renamed this file accordingly copy and paste it to a USB flash drive.

7~ Fire up Multiman and go to the mMOS. Insert your flash drive into the PS3 and await for the newly patched dump to show up on the USB device. Double click the file and it will ask if you are sure just click yes. Provided the image was done properly mMOS it will start to flash the newly patched NOR/NAND dump. If not re-read what was here as I just did it step by step. I had no troubles with this method. Anyhow once it is done flashing simply reboot your PS3 and go back to mM again but this time go to "System Settings" and you will see your new valid IDPS has been installed for good.

I hope this helps a few people out, as I said I will be adding pictures and such today. I am just up at 5am as i can't sleep and needing something to occupy my time. It is fairly straight forward and on a scale of 1-10 I give it a 2, time consuming not difficult.
