Yup. Hit to the guide right away
and the battery can be converted back to normal.
Thanks. it worked perfect :wink:
Edit: nevermind i put the SEplugins folder in the wrong place.. stupid wrong guides ...
Well did you follow the instructions to make a magic memory stick too? Also make sure you are holding UP on the d-pad while you turn the the PSP. It needs to be held until the menu comes up.
Where did you buy the batteries from? I've noticed some sites are selling counterfeit Sony batteries that don't work with Pandora. Another person on here had one of these, and they had the same problem - couldn't change the battery serial.

what if you already softmodded your psp battery into pandora will this still work? will I just have to do the magic memory stick thing because my psp is 3.71 m33 and it is a full brick no recovery mode
You only have to follow the magic memory stick portion of the guide if your battery is already a Pandora.

how would i do this if I have no recovery mode? is it still possible?
No. Read here for information on what to do if you're running official firmware: http://forums.exophase.com/showthread.php?t=6832
Made a brick of my PSP trying to put custom themes in flash0 NOTE: wont be doing that again.....
Anyway I would just like to say many thanks for this tutorial, i followed it to the letter and I now have my little bundle if joy back up and running.
I will say I used my mates PSP cwf 3.90 M33 and had no issues running this.
I tried to run the U.P.M.S. Emerald Installer and I kept getting errors, I know this works with 3.71, but not 3.90.
So as I said thanks again......

I have a question. More than one unfortunately.
Have a phat PSP with firmware OE 3.95 -- would like to convert over to custom firmware.
Per the Guide -- I must have a current custom firmware to do so -- how do I go about creating a pandora's battery and magic memory stick.
I found another thread here that discusses creating a Magic Memory stick using windows XP -- and I followed the steps. I then found a article to covert the battery -- but think I did something wrong. Battery fails to hold charge. Bought new battery presently -- but I keep thinking how can I go to custom firmware.
Or is is best to use a datel tool???
Lost and confused. Trying to make this happen for my nephew. None of his friend have custom firmware.
If I use the datel tool battery -- what is the actual process and then do I follow the guide listed here?
thanks for any help

Well, if you don't have a custom firmware PSP, there is no possible to way to convert the battery, other than by hardmodding it (not recommended). The Datel TOOL battery is already a Pandora so that will work... the other other thing you would need then is the magic memory stick (which I presume you already have?)
The Datel Tool battery can't be used as a normal battery, but you can use it multiple times to install custom firmware on any PSP.

I have a phat psp so i cant test it right now, but if i just stuck with the hellcat pandoras battery, can i load the 3.90 M33 firmware on the slim or do i have to make a time machine and use the firmwares on that in order to hack a slim psp?
so for eg. if i was trying to load 3.90 M33 firmware on a psp slim (using hellcat pandoras battery) that has official 3.60 firmware on it, is that possible or is this made only for phat psps
