Pandora Battery Preparation

1. Make sure you have completed the "Memory Stick Preparation" first.
2. Plug the Memory Stick back in.
3. **OPTIONAL ** Run the "Pandora's Battery Creator" program on the PSP and press Triangle "/" to back up the contents of your battery's flash into a file on you memory stick. The program will automatically exit. *Note:* This step is REQUIRED if you want to make this a normal battery again; otherwise it's optional.
4. Run the "Pandora's Battery Creator" program on the PSP. This prepares the battery. You will not be able to use it normally from now on unless you've taken the optional step above to revert after the fact (should be using a spare so you can keep it around anyways).
5. You now have a "Magic Memory Stick" and a "JigKick Battery". Proceed to the next section to reflash your PSP.

Reflash your PSP

1. Remove the UMD, Battery, Memory Stick, and Power Cable from the bricked PSP.
2. Insert the Memory Stick ("Magic Memory Stick") you prepared beforehand into the bricked PSP.
3. Insert the battery ("JigKick Battery") you prepared beforehand into the PSP.
4. Boot the PSP. A menu will appear. Follow the onscreen instructions to reflash your PSP.
5. When the flashing process is complete, restart your PSP.
6. If all goes well, a blue screen will appear, telling you that your settings are corrupt, and to press circle to repair them. Do so now, rebooting your PSP if necessary.
7. You should now have a 1.50 PSP

Pandora Battery FAQ
Can this Pandora battery downgrade or unbrick any PSP?

Yes, you can unbrick any currently available PSP. This can also be used as a downgrader on a non-bricked PSP.

Can I restore my battery back to its normal state after this process?

Yes, you can if you've backed up the contents of your battery's flash into a file on you memory stick; although, this defeats the purpose of having a battery ready for unbricking. That is why you are suggested a spare battery. Freeplay has found some very cheap batteries. Get them while they're still cheap.
To revert a battery:

Take out normal battery.
Power on PSP with AC adapter only
Once XMB comes up, re-insert Pandora battery
Run "Pandora Battery Maker" and press L+R to restore the ms0:/eeprom.bin to your battery
Can the Memory Stick be reformatted and reused?
Yes, however you will need to redo all of the steps in the "Preparations" section related to the memory stick for reuse as unbricker.

Does unbricking work on TA-082 motherboards?
It is known to work on all motherboard revisions. The reflasher will ask you to apply the patch. Press 'X' to do so.

The readme states that "The firmware in the Memory Stick is not a full 1.50 but a minimal subset."; what's that all about?
It simply means that the PSP will not act as a "complete" 1.5 PSP until you place your normal battery back in and restart.

Minimal subset? Can I install custom firmware?
As stated above, replace your normal battery and restart the PSP so that you've loaded the full 1.5 firmware from flash0 into memory; then you can do as you see fit.

The readme states that "The IDStorage cannot be totally restored, as there is no known way to regenerate it properly."
They're talking about if you bricked due to a corrupted idstorage. If nothing bad has ever happened to your idstorage, you can safely ignore this note.
