Pandora's Battery - Despertar del Cementerio v5

What is it?

A universal PSP unbricker and CFW installer.

Itīs a set consisting of a Jigkick Battery and a Magic Memory Stick which will allow you to:
  • Unbrick any Classic PSP (PSP-100* Model) and Slim&Lite PSP (PSP-200* Model).
  • Upgrade any Classic PSP (PSP-100* Model) and Slim&Lite PSP (PSP-200* Model) from any SONY official firmware (i.e. 3.95) or CFW (i.e. 3.40 OE) to 3.90 M33-3 CFW (Currently the latest CFW by Dark_Alex)
Requirements

In order to obtain one you will need the following:
  • Any PSP already running Custom Firmware (such as OE, M33 or WC). It can be a Classic or Slim&Lite PSP as long is already running any CFW. We said compatible because not all makes will work (Read the Compatibility Section bellow). Using a spare is best, as it will not be possible to boot the PSP in its normal state once the battery has been modified, although there is a "trick" if you only have one battery (Explained further down).
  • A (spare) Memory Stick Pro Duo. At least a 128MB and max 2GB Memory Stick is required to hold all the necessary applications.
  • Kernel_Kevs_Complete_Pandora_Pack
Compatibility

Memory card
  • They MUST be PRO Duo. As long as it's PRO Duo it should work. Memory Stick Duo will NOT work.
  • They MUST be able to hold all the required files (At least 128MB). No larger than 2GB as they cause problems.
Battery
  • Compatible:
    - Sony PSP-100, 1800mAh, 3.6v - Normally bundled with PSPs.
    - Sony PSP-280, 2200mAh, 3.6v.
    - Datel Go Max GM100, Reusable Battery Pack. USes 3xAAA batteries. The serial resets itself to zeroes once the bateries are removed.
    - Datel X2, 3600maH
    - Datel MAX Power, 1800maH, 3.6v (Two models, Black [Model No LB1000] and Silver)
    - Sony PSP Slim Battery, 1200mAH, 3.6v, PSP-S110 (As long as you do not use the Pandora's Battery Creator. Use
  • Not compatible
    - MEGA Lithium, 2600 mAh, 3.6v
    - Sony (Fake) PSP-280, 2200mAh, 3.6v
    - Unknown brand TYP-107, 3600mAh, 3.6v (Gold Letters)
    - Unknown brand PSP-360, 3600mAh, 3.6v (Silver Letters)
Before you start
  • If you have a PTF custom theme set, remove it before we continue.
  • This application requires running under a CFWwith 2.x or 3.x kernel, therefore make sure that the kernel selected in recovery menu is the correct one (2.x or 3.x depending on the CFW you're running.) To changethis, hold the right shoulder button down whilst turning the psp on. Navigate to configuration and press X to change the option.
Creating the magic memory stick
  • Use your PSP to format your memory card. Connect your psp to PC via USB.
  • Download my pandora pack linked above. Use winrar or similar program to extract the contents of the RAR folder to your hard drive.
  • Copy the contents of the folder "Copy contents to root" to the root of your memory card.
  • Click "yes to all" when asked to overwrite files.
  • You now have all files needed to create the magic memory stick and jig kick battery, all files are in the correct place.
  • Go to the GAME Menu of your PSP, select the Memory Stick and press X, then select "Despertar del Cementerio v5" and press X. It will ask you to press the X button to begin the installation.
  • If you would like to free some space in the memory stick, you can safely delete the files 150.PBP and 340.PBP off the root of the memory stick as they will not be needed anymore, however make sure the file 390.PBP remains in there. Once finished, disable the USB Mode safely.
  • You have successfully created your Magic Memory Stick. Now you still need a jigkick battery in order to run it.
Creating the jigkick battery
  • Go to the GAME Menu of your PSP, select the Memory Stick and press X, then select "OS Pandora Battery Tool 0.XX" and press X. It will show a Warning message, press the X button to continue.
  • I suggest you select "Backup battery eeprom to ms0:/eeprom.bin" and prexx the X button. This way you will be able to to recover it at a later stage to its exact original condition, whenever you want to convert tha pandorised battery back to normal.
  • Then select "Convert to Service Mode (aka: Pandora's Battery)" and press X. Now your battery has been Pandorised. You can select "Quit now" and press X. Shut the PSP off. You can use your set now to unbrick any PSP and/or install the 3.90 M33-3 CFW.
You now have a Pandora Battery set consisting of the jigkick battery and the magic memory stick.

Using the set to unbrick/install custom firmware
  • Just grab any bricked or working PSP (Classic or Slim&Lite) running any firmware (Official or Custom).
  • Remove the regular battery and memory stick if applicable.
  • Insert the Magic Memory Stick into the PSP
  • Insert the JigKick Battery into the PSP.
  • The PSP will boot up automatically showing a Menu on screen.
  • Follow the on screen information and options:
    • X Button: To install 3.90 M33
    • O button: To install original 3.90
    • Square button: To dump the NAND to mso:/nand-dump.bin.
    • L+R+Start+Select to restore NAND with IDStorage Keys: Use this option ONLY if the nand-dump-bin file coms from your own PSP. Otherwise you will mess your IDStorage and the UMD Drive, Wifi, etc will stop working.
  • Presssing the X button to install 3.90 M33. The memory stick LED should begin flashing. Wait around 5-10 minutes, when the LED stops flashing the process is completed and you'll be asked to press X again to complete the installation - it's imperative that you do this.
  • Boot up the PSP with a regular non-Pandora battery. If you only have one battery and it's pandorised, then boot up without battery and connecting the charger to the mains with the power cord.
  • You may be presented with a BSOD, but just press X or O to restore settings.
  • Done. You're now running 3.90 M33-3.

Converting your battery and memory card back to its original state

  • Unpandorising the battery: To do that remove the battery, connect your PSP to the mains (A USB charging cable will NOT work), turn the PSP on, insert the magic memory stick, then insert the jigkick battery. Go to the GAME Menu of your PSP, select the Memory Stick and press X, then select "OS Pandora Battery Tool 0.XX" and press X. It will show a Warning message, press the X button to continue. Select "Flash only serial from ms0:/eeprom.bin" if you backed up the original eeprom or alternatively select "Convert to normal mode (0x12345678)" if you did not. Press X. Your battery is now a regular battery. You can now select "Quit now" and press X button to exit the application.
  • Unpandorising the memory stick: You can still use a magic memory stick it for regular purposes. It will not give you any problems. The Magic Memory Stick should still work in the same way for savegames, homebrew, MP3, Videos..., however if you want to convert it to a normal memory stick again you just have to format the Memory Stick from the Settings Menu of your PSP.
Pandora for those without a spare psp

For those who dont have access to another psp, dont worry, tergazzi has very kindly wrote a tutorial on manually creating a pandora battery.

Heres the link:

Once on 1.50 or Custom firmware you may want to revert your battery back to normal, heres how:
  1. Remove battery from psp
  2. Connect AC adapter to PSP
  3. Insert battery
  4. Run the Pandora's Battery Program from Game menu of the PSP.
  5. When the Program is loaded, hit the square button to turn it into a normal one.
