Can I use a fat PSP pandoras battery for the PSP Slim? and how ?

I want to know , i have a pandora's battery (the battery is fat psp battery) i heard the slim psp's battery was flat, wich means that the old one wont fit right ?? or do i just not close the battery cover and it will downgrade like it would on a fat psp?

 

you can use it in your slim,but it won't downgrade to 1.50 you will need to alter the magic memstick i think

nstalation:

The instalation is done using pandora battery and requires a fat psp with 1.50 or
custom firmware with 1.50 support to run a installer.
However once the memory stick installation is done, you can use it in whatever psp slim without
repeating the process again.

We want to thank C+D Team for having created Pandora and having opened the path to custom ipl's,
without which this cfw wouldn't exist.

Steps:

- Create a pandora battery and a pandora memory stick using the C+D team tools.
- Run the fat psp with the pandora memory stick inserted, but with a normal battery.
Copy the directories pandora_slim and pandora_slim% to PSP/GAME or PSP/GAME150.

- Download official sony firmwares 3.40 and 3.50, and put them in pandora_slim directory
with names 340.PBP and 350.PBP.

To avoid confussion: These firmwares are used ONLY to extend the memory stick pandora kernel.
NOTHING FROM THOSE FIRMWARES WILL EVER BE FLASHED ON THE SLIM.

- Run the program. It will quickly extract some prx's overwrting some of the pandora memory stick.

- Insert the pandora battery and the memory stick in the psp slim. It will boot. You won't see
anything on the screen, because that kernel doesn't support the slim screen, but it is OK, you
don't need a screen for the installation of 3.60 M33.

From here, you have 3 options:

- Press X to install M33. The process will last just few seconds, since the installer only
needs to install the M33 custom prx's and IPL. After the process is finished, the installer
will shutdown the psp automatically.

- Press L+R+triangle to uninstall M33 and go back to original 3.60. Note: this can't unbrick a
psp slim, it will just remove M33 ipl. There is currently no unbricker for the psp slim, but
we plan on doing one in the future.
After uninstallation, psp will be shutdown automatically.

- Press square to dump the PSP Slim nand. Watch out: you need 66 MB of free space in the
memory stick for this, otherwise your memory stick may end corrupted.

This option uses the team C+D nand dumper. When the memory stick orange led stops blinking,
the process will have finished, and you can either shutdown the psp, or use one of the two
previous options.

 

Theres actually an update 3 of Dark_Alex universal unbricker which has screen support for PSP SLIM now (The unbricker menu shows now for PSP Slim).

This will allow you to unbrick/upgrade your PSP SLIM or FAT straight to 3.71 M33-2 custom firmware (Your PSP does not have to be bricked in order for this to work).

Since you already have a Pandora Battery + Magic Memory Stick all you need to do is alter the Magic memory Stick for this universal Unbricker. Pretty much the same as Sicdude has posted above but this is an updated version.

Below is a mini-guide on how to alter your Magic memory Stick to install this universal unbricker. The reason this is universal is because it works for both FAT and SLIM PSP systems. No need to have 2 Magic Memory Sticks for both FAT and SLIM systems.

First place the Magic memory Stick in a fat PSP running custom firmware above 2.XX (Make sure the kernel GAME folder is set to the 2.XX or 3.XX kernel -- NOT 1.50 KERNEL)

Download the Universal Unbricker HERE. Extract it and place the despertar_cementerio folder into the /PSP/GAME folder.

Now download the 3 official firmwares below and place them in the ROOT of the memory Stick.

1.50 HERE rename it to 150.PBP and place in root of MS.

3.40 HERE rename it to 340.PBP and place in root of MS.

3.71 HERE rename it to 371.PBP and place it in root of MS.

Now go to Game Menu Memory Stick and select Despertar del Cementerio to modify the Magic memory Stick (This modifes and replaces the msipl.bin file on the MS)

After it is run you can delete the 340 and 150 PBP's they will no longer be used.

Now stick your Pandora battery into your slim add the memory Stick and the menu should come up. Press X to install 3.71 M33-2 CFW or you can press O to install the official 3.71 Sony firmware.

Thats all there is to it.

 

is it must to make the universal memory stick with fat psp.

 

where is the root of the ms is there a folder

 

when you open the PSP on the computer and the folder PSP appears, that is the root of your memory stick.

 

Ok heres a question I successfully made a pandora batt and mem stick and got my slim runnign custom firmware..I copied ALL the info on my mem stick and am keeping the spare pandora battery..If i want to update anothers slim can i jsut copy the mem stick I have saved on my pc? or do i need to REmake the pandora mem stick?

 

well if you messed with the files i suggest to you to redo it cuz you dont wanna be bricking anyones psp do you?? ya so keep your battery the way it is and just change the files on the memory stick.

 

I copied everythign that was on it..only reason because I had such a hard time getting it to work for my slim..I got it to work on my fat no prob

 

i got a psp slim sony official version 3.71 and i bricked it, i have a fat pandora battery and psp fat with cfw 3.71 m33-3 is there anyway i can un brick my psp slim

 

Read the previous post above your answer is in front of your eyes.

 

i have firmware version 3.72 and i have the v3 dark alex thing.. but since its 3.72 i can't use the M33 what would i do? i have some 3.72HX-1 and i dont know if thats wat i should do. from what i've read it's the same as 3.71m33 but for ver 3.72. is that correct? if not what can i do?

 

It doesn't matter if your on 3.72 official firmware. You can still install 3.71 M33 onto it using the Universal Unbricker V3 (v3 dark alex thing). When you read that PSP SLIM's can not be downgraded that means it can not be downgraded to 1.50 firmware like the FAT PSP's can. But if your on 3.72 or higher you can install the 3.71 M33 custom firmware to the SLIM.

I would stick with 3.71 M33 and not 3.72 HX they both are pretty much the same but M33 is still a little better then HX.

 

larrylje, Can you please give me another link for 3.71 download, I cannot access the one you gave. Thanks

 

Use this guide HERE instead it is easier.
