PSP Classic - Perfect Pandora What will I need? First we need to go over what you need to create a Pandora's battery: A PSP Classic with a custom firmware, or homebrew compatible firmware. A PSP battery you are willing to convert Don't worry, you will be able to use it as a normal battery when we are finished. A USB cable. The following files: Part 1: Pandora Battery Files. Pandora GUI. Alternate Links: MaxConsole, RapidShare 1.50 Update File. Part 2: Booster's Multi IPL Loader. Part 3: Pandora Extended Menu. Alternate Links: Megaupload, Rapidshare. 1.50 Update File. Part 4: MaxSafe Pandora Menu. Part 1 - Creating a Pandora's Battery Extract the Pandora GUI RAR downloaded for 'Part 1' found above in What will I need?. Install Pandora GUI. Start Pandora GUI. Either download the 1.50 Update file from above, or use the built in feature found in Pandora GUI under '1.50 Sony eBoot'. If you downloaded the above eboot, then extract it and place it on your desktop. Select the button 'Load Local File' in Pandora GUI, and select the extracted eboot found on your desktop. Plug your PSP in via USB to your PC. On the drop down menu, select your PSP's drive letter (for example, J). If on a custom firmware, under 'PSP Location' on Pandora GUI, select PSP/GAME150. If on a homebrew enabled firmware (i.e.: 1.50) use PSP/GAME. Make sure you have backed all data you intend on re-using, like savedata and music. Press the 'Format My PSP'. Once finished, select the 'Copy Files' button. Now do the following: Disconnect PSP from USB. Go to GAME > Memory Stick under the XMB (PSP Main Menu). Run the application. Once finished, plug your PSP back into your PC via USB. Select the button 'Write IPL'. Once finished: Disconnect the PSP from USB. Run the new application found under GAME > Memory Stick. Press X to convert your battery. You have finished Step 1! DO NOT DELTE ANYTHING FROM THE MEMORY STICK. Part 2 - Installing Extended Pandora Boot Menu If you don't have a spare battery, then use your AC Adpater to power your PSP for now. Extract the RAR you downloaded to your desktop. Inside the newly extracted folder, run the program 'install_psp_ms_multi_loa der_ipl.cmd'. Plug the PSP in via USB to your PC, and toggle on USB. The installer will auto-detect your PSP. Press 'y' to accept the question "Are You Sure ?[Y]" message to install the IPL". Remove your PSP from USB, and take out your memor stick. Turn USB back on, with the memory stick inserted. Create a new folder in the root of your memory stick named 'ipl'. Copy the file named msipl.bin from the root of your memory stick, to the folder you have just created ('ipl'). Rename the newly copied 'msipl.bin' to '150ex.bin'. In the RECOVERY_LOADER folder found in the RAR you extracted earlier, you will find a file named 'pspboot.bin'. Copy 'pspboot.bin' to the ipl folder on your memory stick, and rename it to 'ipl.bin'. Turn off USB, and remove the memory stick. You have finished Step 2! Step 3 - Installing Extended Pandora Bootmenu If you don't have a spare battery, then use your AC Adpater to power your PSP for now. Extract both the 1.50 Update file, and the epbm084 RAR file to your desktop. Copy the folder PSP, from the epbm084 folder to the root of your PSP, and say yes to any overwrite warnings. Place the 1.50 update file in the root of your memory stick named 'UPDATE.PBP'. Navigate to GAME > Memory Stick in the XMB. Run the Installer. You have finished Step 3! Step 4 - Install MaxSafe Menu If you don't have a spare battery, then use your AC Adpater to power your PSP for now. Download the RAR file, and extract to your desktop. Copy the 'PSP' folder to the root of your memory stick, saying yes to any overwrite warnings. Navigate to GAME > Memory Stick in the XMB. Run the MaxSafe Installer. You have finished Step 4! FAQ When booting your PSP, you have 3 options: Hold the L button to boot into the Pandora Menu. Hold R to boot into Recovery. Do not hold anything to boot normally. Why does my PSP restart after turning on from stand-by mode? You must hold the L button, or your PSP restart instead of turning on from where you left of. Do I have to install the MaxSafe an/or Pandora Extended Menu? No, you may skip the installation of both. I don't reccomend you installing the Multi-IPL-Loader either if you do not intend to install these.

PSP Slim - Perfect Pandora What will I need? First we need to go over what you need to create a Pandora's battery: A PSP Slim or Classic with a custom firmware [Classic PSP can also be on 1.50 official]. A PSP Classic or Slim battery you are willing to convert. Don't worry, you will be able to use it as a normal battery when we are finished. [/LIST] A USB cable.

Navigate to GAME > Memory Stick in the PSP's XMB, and run the application. Choose the following option: Press R + X. Then press R + L + X. Restart the PSP, and copy the folder 'pan3xx' to 'X:/PSP/GAME/'. Copy the 1.50 EBOOT to your root again. Start the application from GAME > Memory Stick. Choose the following option: Press X.

How do I switch active folders (kd352, kd, etc.)? Press R or L trigger in Ultimate Loader to switch active folders without launching Pandora or Extended Boot Menu.

Removing the installation of Pandora If you feel the urge to, or simply want to remove Pandora from your memory stick, do the following: Load the Pandora 3.XX application on your PSP, from GAME > Memory Stick under the XMB (Main Menu). If you do not have the application on your memory stick, download it from here. After extraction, place the folder named 'pan3xx', in 'X:/PSP/GAME/'. Select the option that says 'Restore Battery', or something similar. Once finished, exit the application and turn on USB mode. Format your memory stick. Remember to back up any data you wish to keep (ie Savedate). After format is complete, restart your PSP. Your PSP is now un-pandorized!

To do this, plug in your PSP into USB mode, then copy the 3.11 EBOOT file (named EBOOT.PBP), into the PSP/GAME/UPDATE directory. UPDATE must be in all caps. After that go to the game menu of your PSP, the memory stick icon, then start the app 3.11 Update. If you already are at 3.11, then download the necessary files, and extract them. In the 3.11 downgrader folder, you should be presented with these sets of files. Spoiler for Image: I'm on Ubuntu Feisty Fawn, so your theme may be different, however the files should be the same. The SRC folder is the source of the program, and is useless to you unless you're a programmer. The checkworks folder is the check the legitamacy of your EBOOT. However, the MS_ROOT one is the one that'll be helping you do the downgrade. Open the folder, then copy the PSP folder to the topmost part of your memory stick. This is called the root. Spoiler for Image: The contents of yours may vary. If your OS asks you to overwrite the contents of the PSP folder, hit OK. You won't lose any of your data. Spoiler for If you want to restore your IDStorage, ignore otherwise: If you do, then start the app ID STORAGE RESTORER in the game menu. Once you do that, you're done, and are free to update to an official firmware. Once you do this, rename the 1.50 update you downloaded to UPDATE.PBP. Place this in PSP/GAME/UPDATE, which is the same place where you put the 3.11 update. Don't jump ahead and run it though, you'll get a "Game Could Not Be Started" error. Your next step is to run Lumines. The game will not start like normal however, and either one of two things will happen. You get a red screen. If this happens, try again. You get a blue screeen. This is good, and means you can now downgrade. Once you get the blue screen, run the X.YZ update in the game menu, under the memory stick icon. You can also check to see if HEN is running, by going to settings, system settings, then system info. It should say 3.11 HEN. If this is your first time downgrading and you have a TA-082, then the downgrader will ask you to patch your motherboard. Press X. After that, then the downgrader will ask you to assume all responsibility for your PSP, as the downgrader runs the possibility of breaking it. This chance is very very low however, less then 1%. Press X, and your PSP will start being downgraded. After it finishes, it will either say your settings are corrupted, in which case you'll have to run the NETCONFIG restore tool under the game menu, or simply press X to restart. Either way, you are now the proud owner of a 1.50 PSP

FAQ My PSP bricked! You suck! Not my problem, it's your responsibility. I thought Fanjita said he retired? Fanjita only retired from high level trust projects. Not to mention this was something he promised long ago. What are all the other files in my game folder on the XMB? They are homebrew examples from the PSPSDK. You can use them to make sure HEN is running, but they don't do much. The cube sample is sort of cool though Can I format my memory stick after the downgrade? Yes. How can I donate to Noobz? From their homepage.
