TUTORIAL: Make a Pandora's Battery without a homebrew PSP!

I have exactly the same battery a Gekko.

My PSP (PSP-1002) was working as usual, then a game I purchased was performing a firmware upgrade and froze during the upgrade resulting in my PSP becoming a brick. Which I switch the power switch the green light comes on for about 8 seconds then turns off. No other lights no nothing.

After searching on the Internet for hours I thought I would give the Pandora mod a try, even though different posts made me think this still wont work. I was confused with regards to it working or not, so I decided to do it and see what happens and provide all the users with this style battery with some feedback. There is two eight pin chips on the same side of the board, so I wasn't sure which one was the EEPROM until another person posted that the LO2 chip was the EEPROM and provided a data sheet on it so I thought it made sense to try this chip over the other chip.

So I disconnected the PIN 4 by cutting the pin and made sure there was a suitable gap. PIN 4 was shown as ground on a EEPROM specification page, on previous post.

I successfully created a 2GB Memory card using the instructions from theultimatepandorapack.rar. I created the card via my PC using XP SP2, and followed the instructions for the Slim PSP battery. Formatted fine, copied the data perfect, and msipl.bin was created succesfully. No errors and I copied the hidden files as well.

After doing all of the above I can confirm that my PSP does exactly the same as it did before any of the above work being done. If I am able to find an fat battery can anyone confirm that this should still work or does it sound like my PSP is now an expensive paper weight?

Thank you to all of your posts, it has at least given me a chance at fixing something that Sony should allow users to do themselves anyway, especially in my case.

My only other option is to pay Sony to fix something that was through no fault of my own. Which I think sucks.

Well i decided to give this a go. It worked perfectly. Awsome. Now im thinking i want a normal battery back can i just solder a wire from my lifted pin to ground or does it have to be in that spot?

That Newbie installer was really smooth aswell.

EDIT: Nevermind it does work. I decided to try and its fine.

So I was working on making a Pandora battery, and knocked the covering off the 4.000(EPROM). When I was trying to place the covering back on I snaped the damn chip in half. Here's the thing, the battery will still take a charge but I don't know if it will power the unit on. I'm S.O. L huh?

I have a fat PSP, its bricked, battery charges and when I try to turn it on the gren light turns on for some seconds and then turns off. With the charger and no batter it did the same thing. I tried another battery and the same thing. Now I believe its bricked because it seems that my kid tried to update and then turned it off becasue of no network connection. Any way I made the Pandora Battery by completely removing Pin 5, but now when I place the battery in, the green light just blinks and it doesn't stay steady green. Did I mess the battery? Is this normal? I don't have the MMS yet.

not unless you put the pin back in place

Ok so just to clarify I don't need another battery for this to work as long as I re-solder it after using it in service mode. (As in to power it)

Thanks
