JigKick Battery

This is a battery with its serial changed to 0xFFFFFFFF. When a psp's battery serial number is changed to 0xFFFFFFFF the PSP boots the ipl from sector 16 on the physical drive (the Magic Memory Stick). This file can be installed by several programs like using msinst in team c + d's Pandora Battery Package. This unlocks the service mode of the PSP and launches the IPL from the Memory Stick (instead of from flash0). Sony have done lots to prevent this and the new PSP Slim motherboard (TA085v2)can not write to the battery EEPROM at all because Sony disabled it, therefore you must use the hardware mod. Also any new battery which is official (Including Phat and Slim) and all fake batteries cannot be converted in a Pandora's Battery. So the advice is to buy a new one and use the original one as a Pandora's Battery. This is ideal becuase a Pandora's battery can do lots of useful things like run the Time Machine and along with a Magic Memory Stick you can Unbrick/Downgrade any PSP. Or you can just use the orginal one and convert it back to a normal battery, if you don't want to spend any money. You can also buy a Datel Tool Battery. This is the same as a "Original" JigKick Battery. But, even if you have a Datel Tool, you still have to make a Magic Memory Stick.

Softmod

For this you will need a spare compatible battery. And a homebrew PSP 1.50 or a CFW PSP eg. 3.80 M33 with 1.50 Kernel addon. You wil first need a pandorable battery. You can check if yours is by this list.

There is now a method that will enable users of custom firmware above 3.71 M33 which does not automatically have the 1.50 firmware kernel to create a Pandora battery, by interfacing directly with the PSP's SYSCON chip. (Or for those who are on Slims) This method uses code by SilverSpring, and can be found here.

Requirements

   A Pandorable battery (spare if possible), check if it is pandorable in the list below
   Homebrew Capable PSP. Version 1.50 / or any CFW with the 1.50 Kernel addon or a homebrew-enabled PSP.

Software:

   The original Pandora's battery creator only for suitable fat batteries only. However, other alternatives such as the UPMS Installer, Hellcat's Pandora Installer for 3xx kernels, can convert a Slim battery to Service Mode successfully. Download pandora files; battery files included in it, only works on 1.50 or CFW with 1.50 kernel.
   Cory149's tool which can even convert some old slim batteries and fat suitable batteries.

   First make sure you have the requirements, then download the software depending on what firmware you are on.
   If you are on 1.50/CFW with 1.50 kernel download the pandora files; which can convert only phat batteries, since it only works on Phat PSPs. However, the alternative options for Slims are available.
   If on CFW with no 1.50 kernel download Cory149's tool, which can convert all batteries, and works on both phat and slim PSP's, only on CFW.
   Whichever one downloaded put it in the GAME folder, but you will have to change your kernel depending on what you downloaded.
   If you downloaded the Cory149 tool, make sure it is set to 3xx kernel.
   If you downloaded the Pandora tools then make sure it is set to 1.50 kernel.
   Run it on the XMB with the battery and Press triangle if you plan to make use it for normal use again.
   Then go back on the program and press X to convert to Pandora's Battery.
   If successful, take it out and plug it back in with no MS, (or an MS that has an ipl that cannot boot with a Pandora Battery) the screen will stay blank. 

Hardmod

For this, you will need to open up your battery, and maybe need some soldering skills, and guts. The best thing to use is a Datel tool battery if you aren't sure about what to do. Datel Tool Battery Datel Tool Battery What do I need?

   Extra PSP Battery
   Knife/Screwdriver
   Soldering equipment (To prevent shorting and to revert battery) 

Making the JigKick Battery on Normal/Phat PSP Battery

You also can use a Datel Tool Battery to use (YOU STILL HAVE TO MAKE A MAGIC MEMORY STICK IF YOU USE DATEL TOOL!) 1. Open the extra battery with a knife or a screwdriver. Do not slide the tool all the way into the battery or you will run the risk of shorting it.

2. Remove the top of the battery. (Or swing the case open)

   Image:Pandoranocfw2.jpg 

3. Remove (or disconnect) the leg of the chip next to the word C04, IC104, or IC04. This is better to do this with a knife. Once again, be careful not to touch the other objects as you can short it. You can always iron the leg back on if you want. (Requires soldering tools. Also, soldering is easier to do if the leg is still attached to the board, but not in it.

   If successful, take it out and plug it back in with no MS, the screen should stay blank. Also, the power light will automatically come on. However, if not, you may have shorted the battery or it needs a charge. 

Making the JigKick Battery with a PSP Slim battery

There are two methods of hardmodding a slim PSP battery into a JigKick (Which will be referred to as "Blue Square" or "Red Circle" as indicated by the picture)

image:slim.jpg

Red Circle:

1. Open the extra battery with a knife or a screwdriver.

2. Remove the top of the battery, and pull back the motherboard

3. Remove the leg indicated by the red circle (Farthest left, as shown), it is better do this by soldering it!

4. Fold the motherboard back down, and replace the top of the battery

   Scotch tape works perfectly to hold the battery together

5. If you want to turn it back into a normal battery, re-solder the leg down

Blue Square:

1. Open the extra battery with a knife or a screwdriver.

2. Remove the top of the battery, and pull back the motherboard

3. Scrape away part of the trace (Preferably perpendicular to) indicated by the blue square

4. Fold the motherboard back down, and replace the top of the battery

   Scotch tape works perfectly to hold the battery together

5. If you want to turn it back into a normal battery, simply use a pencil to fill in where you cut the trace

   If successful, place the battery into the PSP without a Memory Stick inserted. The PSP should boot automatically with the screen staying blank.
