OK, I will write this tut, I intentionally bricked my M33 PSP to test this.
For those new to the PSP hacking scene, this little app can restore your PSP to a limited version of Firmware 1.50 (Think of Firmwares as Operating Systems of the PSP much like PC has Windows, like Windows 95, 98, ME, 2000, XP, Vista and such), but it will still allow you to update to any OE, M33 Custom Firmwares and such
For those that do have a Custom FM that got bricked, and cannot get into the Recovery Menu, then this little App of Joy is for you, no need to throw your PSP in anger, use it as a expensive paper weight and such
*This can be also used as a universal downgrader *
Before you start any of this, put the msinst, mspformat, folders in you C Drive (HDD) where you see Program Files, WINDOWS, folders and such, you will need to put those right there for the upcoming command prompts you will need to use
Ok, here are the basics of what you will need in order for this to work
1.) You will need a Spare PSP Battery (use Official Sony PSP Battery, works the best), this is needed because according to the Read-ME file, its used to turn it into the "Magic Battery", but you can use your own, *BUT*, make sure you back up the files when you create it to turn it back into a normal battery
2.) You will need a spare Memory Stick Pro Duo as the regualr Memory Stick Duo (like the 32 MB) will not work, if you have only one, back everything up from it because you will need to format the Memory Stick and that wipes everything from the Memory Stick, or if you do have a spare one, then its best to have a 256 or above, but no larger than a 4 gig Memory Stick
3A.) You will need another PSP that is working that has FM 1.50 or any Custom FM, if you do not have a Spare working PSP, then ask a buddy, you will need this Spare PSP with those FM mentioned because you will need to run the "Installer" Eboot (remember, only 1.50 and any Custom FM will only Boot Eboots that are not from Sony, like you would with Homebrew) and if it is a Custom FM, make sure you switch it to the 1.50 kernel in the Recovery Menu
3B.) If you do not have access to a working 1.50 PSP/Custom Firmware PSP, then scroll the the bottom of this tut to see the instructions for it
*NOTE* If you have a fat PSP with 3.71M33, make sure to have the 1.50 plugin first before you set the kernel to 1.50 in the Recovery Menu
****Installation and Usage Instructions****
OK, I will now go through he Installation Instructions and will try and be clear as possible, its really easy though, no big terms
1.) First, Connect the working 1.50/Custom Fm PSP under the 1.50 Kernel to the Computer Via USB Cable
2.) *IMPORTANT* if you have only 1 Memory Stick Pro Duo (remember, only Memory Stick Pro Duos will work for this) then back everything up as the reason, you will need to format it and thus, will wipe out everything from your Memory Stick, if you have a spare 256 and above, then Format it in the PSP with the PSP's Format Utility (Settings>System Settings>Format Memory Stick) and Format the Memory Stick because this Memory Stick you are about to use will be the "Magic Memory Stick"
3.) When you Finish Formating the Memory Stick inside the PSP, go to the USb Connection in the PSP to connect the PSP to the Computer
4.) Ok, this gets a little difficult here, I will do my best to say it easy, ok now that your PSP is connected to your Computer, In Windows, select Start>Run>CMD and then open the Command Prompt
5.) Once you have Command Prompt open, then go to "MY Computer" in the Start Menu and look at what drive your PSP is under, for Example, my PSP is known as Removable Drive J: in my computer, so it can be different on any computer, so I will use J for this tut
6.) Now that you got your PSP drive location, go to the Command Prompt, and Type this Exactly like I do, but I will be using my drive letter for this tut, so my PSP drive is J, but remember to put the drive number of your PSP instead of J, and when you type the command in the Command Prompt, make sure to have a space between mspformat and your drive letter, and then when you open the Command Prompt, you should see sumthing similar to this depending what your computer name is and such
Code:
C:\Documents and Settings\Spartan 117>
before you type in the command below, type this first
Code:
cd C:\
then this command
Code:
cd mspformat
then this command
Code:
mspformat.exe J
7.) Now once you hit enter after typing that command, you will get this prompt or something similar
Code:
C:\mspformat>mspformat.exe J
You are about to format the drive J.
All data will be lost. Do you want to continue? [Y]
8.) Type Y for yes
9.) Then you should get a prompt similar to this
Code:
Drive successfully formatted, and partition moved.
10.) After Formating your Memory Stick, then disconnect USB Mode in the PSP and once you do that, take the Memory Stick out and reinsert it into the PSP (*Note* all this still applies to a good working 1.50 PSP or Custom FM PSP) and after you reinsert the Memory Stick, go to USB Mode once more to connect to the Computer
11.) On your PSP, make sure you have the PSP folder and inside that Folder, you have GAME and GAME150 (GAME150 if you are using a CF PSP), if they are not there, then make them
12.) Once you make them, then copy the folders Battery and Battery% in the GAME folder if you are using a 1.50 PSP, or the GAME150 if you are using a Custom FM (this still applies to the working PSP you are using to generate this files needed), and after all the file transfers, exit USB Mode
13.) This is really the important part, now choose which battery you will using as the "Magic battery" and insert that battery you will be using for the Magic Battery
14.) Once you choose the Magic Battery you are using, then make sure you have those folders (Battery, Battery%) in their correct places, then exit USB Mode and go the the GAME Icon on the XMB of the working PSP, and run the "Pandora's Battery Creator" Eboot file like you would with any other Homebrew game, app and such in the PSP
15.) ***OPTIONAL - But Very Important *** within the app, Press Triangle to back up the contents of your battery's flash into a file on you memory stick. The program will automatically exit. Run "Pandora's Battery Creator" one more time. *Note:* This step is REQUIRED if you want to make that Magic Battery back to a normal battery, its optional if you want to keep that battery as a Magic Battery for good, just label it so you won't confuse it with your normal PSP batteries
16.) After you do that above optional step, then run "Pandora's Battery Creator" again, but this time, press X to make your Battery into a Magic Battery, after that, the program will exit again for you
17.) Go to USB Mode again
18.) Download and Copy the Original FM 1.50 Update (it is found in the download section of this site) and put it in the Root of the Memory Stick, and rename it to UPDATE.PBP and make sure its the Eboot file, not in a folder, just the Update itself on the Root (Root means its the top most part of your PSP where you see the PSP Folder)
19.) After that, then get the folder called "Installer" and "Installer%" and put them according to what FM you got (for FM 1.50, put them in the GAME folder, for Custom FM, put them in the GAME150 folder)
20.) After you put those folders in the correct places, then exit USB Mode
21.) Once out of USB Mode, then go to your GAME Icon of your PSP XMB and run the "Pandora's Battery Firm. Installer" like you do with regualr Homebrew and such
22.) Once in the app, press X to unpack the 1.50 firmware files into their correct places. The program will exit for you. If this step fails, go back into USB mode and rename "UPDATE.PBP" to just "UPDATE", then try again.
23.) Once finished with the above step, then go back to USB Mode and look at your Memory Stick Root, you should see the UPDATE.PBP/UPDATE (this applies to whichever way you named the update file) and the PSP folder, and now you should see another file called "msipl.bin"
24.) Once in USB Mode, copy "msipl.bin" into the folder called "msinst" that was extracted from the ZIP file that you downloaded
