I was thinking another battery also but apparently you can flash your original back to normal while using the charger.

Some people here are still having trouble so here's a guide I wrote last night but couldn't post here because the site went down. Pay very close attention to how I made mstinst work.

1. unzip pandora.zip , keeping the directory structure intact.
2. Insert pro duo in PSP (homebrew compatible), and start USB mode from XMB
**My PSP is the I:\ drive on my computer. Replace "i" with yours in the following steps**

3. Right click on START, then click explore, Right click on i:\ and select format.
4. Click start ->> run --> and type cmd and hit enter.
5. go to the directory with mspformat.exe, (ex. C:\Documents and Settings\Mike\Desktop\pspRecover\mspformat)
6. type "mspformat i" then press enter (no you don't type i:\ for some odd reasom)
7. When that is done, go to i:\ and create directory PSP and PSP\GAME
***note: if you're using custom firmware be sure to set GAME to kernal 1.50 in the recovery mode***
8. Copy the 1.50 update to i:\update.pbp
9. in your pandora directories that you extracted, click on battery and copy the 2 directories to i:\PSP\GAME
10. Do the same for both directories within installer
11. With psp, exit USB mode and go to games... now run the installer
12. when that is complete, go back to USB mode
13. in your command prompt (if you left it open) type "cd.." then enter, then "cd msinst" and enter
14. type "mstinst i i:\msipl.bin" and press enter. folow prompts...
15. Now exit USB and run Pandora's Battery Creator from the PSP.

Your memory stick and battery are now set up!!!

You should be able to follow directions after that. But when it tells you to press X to shutdown, you MUST put in a normal battery before restarting. In fact... (assuming you're doing this with a power cord the whole time) as soon as you get to the unbricker menu, you can pull out pandora's battery and put the original back.


My Observations so far:
To use, place battery and stick in PSP WITHOUT IT PLUGGED IN. If it is plugged in, it *might* just boot normally (if you put it in sleep move vice a full shutdown)

I saw an option to copy the battery's eeprom in the pandora's battery creator so I did it. Then I used the program and started it up with only a power cord. After I was in the XMB, I put my Pandora's battery in and fired up Pandora's battery creator again and used the command to reflash the eeprom using the file I dumped in the previous step. Actually I tried it twice because both times I got the error: "error writing at address 0x14".

BUT.... It works as a normal battery now! (simply inserting the battery at any point seems to trigger the 'unbricker' mode and you won't realize it until a cold reboot, so my advise is that after you convret your battery back to normal, fully shut down and reboot with a DIFFERENT battery just to be sure, then you can use your original again and you can do whatever you want with the memory stick, including adding games and stuff and leave the formatting alone)

As for people asking about working with a formatted flash 0... sorry but I'm not brave enough to try that! If you live around Lemoore, Visalia, Fresno, or Hanford California then PM me and I'll be happy to give it a shot on yours but I'm not about to format a flash 0 on purpose!

As the readme says, Memory stick Duo will not work. ONly Pro Duos. with that said... if you do the above and wind up with a memory stick that only makes your PSP memory access light up(blinking)... then you tried using a 32MB stick or your pro duo is a fake. The only way to fix that memory stick is to format it through windows using a card reader (hey at least it can be fixed).

Another update: Apparantly I've had to use my spare battery to get out of service mode because I'm just using a USB Data/Charger cable. I Guess pulling pandora's battery and a cold reset with the A/C adapter also works so everything can be safely done with only 1 battery.
