no it wont brick it if you are useing unversial unbricker have done quite a few any one in glasgow scotland want it done for free pm me

 

I put my friends Pandora Battery and Magic mem stick in my psp the pandora menu didn't show up and now the psp wont boot at all so im trying to use this to unbrick it but the mem stick i originally used for this is having the same problem as the guy i quoted.

EDIT: I was able to fix. i unbricked it but my regular battery wont boot. should i plug in to the charger?(ill look now)

 

I've been reading a bunch of different stickies and such for the past 4 hours and I am stuck. I followed these instructions and created the memory stick and pandoras battery off a PSP phat with 3.71 M33-4 that I had bought. I also have a new PSP 3.71 slim I am trying to upgrade to custom firmware but I am not sure what I am doing wrong. I put in the magic memory stick into the PSP Slim 3.71 then pandoras battery and nothing shows up on the screen. The green power light comes on and thats it. I read that I am not supposed to see anything and I should just hit x and it will install the necessary files, then run the mux program to install the updated firmware. I think I am missing a really big step somewhere. I am getting really frustrated can someone please help

 

you need to put stick in hold top left button then put battery in

 

You do not have to hold the L trigger button down as last user instructed.

Plus the blind install you are referring to no longer is an issue since the easy installer was updated with video support on SLIM PSP's.

The issue is more then likely that the Magic Memory Stick was not properly made. Reasons for this are Incompatible Memory Stick/Vista

Try using a different Memory Stick and or Windows XP (WinXP 64-BIT also has issues as Vista does).

 

Fantastic work guys! I'm a total n00b here (1st post!!)

A while back I got a Fat PSP - that I managed to get custom FW due to the lumines hack. Since then I created a Pandora battery/memstick using the original method. A friend tried it and it works.

Now I'm thinking of getting a PSP Slim as well, and was wondering if I can use my existing Fat pandora battery? I'm pretty positive I need to generate a new memstick for the slim, but it would be great if I can keep using my "original" battery..

I apologize if this has been answered, but I did not see a clear conclusion on such a scenario in the OP. I read a couple of pages as well, but this is a long thread!

Thanks!!!

 

@tosvus

yes.

 

Thanks pwr0n, I appreciate the answer

 

Any chance you could get this to work under 64 bit systems?

 

yea vista 64 bit is a no go on the other hand XP 32 works well. my memory stick was the problem also. thanks alot

 

Hi I managed to downgrade my PSP using DC5..but ur guide was a big help, no doubt.

Since its my first time, I think u should add these things to make it clearer:

1) Hold L then turn on PSP, to boot up to Pandora menu
2) Use ORIGINAL / DATEL fat psp battery. Fake ones don't normally work.

although im not sure if the second is entirely true. While going thru the Pandora OS readme, i noticed it says "Compatible with SLIM batteries". Is this true? Does that mean it doesn't need hardmodding?

 

Hi, I have a fat psp firmware 3.90 m33-2. Its full brick, which there is black screen everytime I turn on the PSP. I tried your method lots of time, I have a sandisk 256mb MS, and a pandora battery. What is wrong with the method? Can your method be installed blindly without knowing which procedure you are pressing? Please help since my bricked PSP has not been fixed for over 1 month.

 

After you're done making the pandora's battery and memory stick, put them in the bricked psp. Try holding the L button when you put the jigkick battery in.

 

hey

im new to this so please forgive any silly questions

i have a psp slim with 3.72 ofw, 1gb sandisk mem card and a datel max power tool, i have gone through the guide to the letter, when im installing files on the mem card it misses the last screen it just goes to the credits and then when i put my battery in nothing happpens the screen doesn't come on and the only light that comes on is the power light. please help

 

hi i have had the the same problem that vampiro93 had jus wandering if there was an awnswer to his question. thanks

 

What if I have 3.73 will it still work ?

 

1. It works with all firmwares.
2. To change to CFW, you need a datel TOOL battery or modify your battery (either with software or hardware). This is called a pandora's battery.

If you have a PSP with CFW (or a friend's), you can softmod your battery to make it pandora.

You can also open the battery, and modify the hardware to make it pandora.

If you can't or don't want to do any of these get the Datel TOOL battery.

3. Please do your research instead of asking the same questions over again.
