How to create a Pandora's Battery and Slim MS without a Fat PSP

[Pirate-M.Lifnen]

Okay, I'd like to make this perfectly, absolutely clear.
I did not make this guide.
This guide was made by r1tony of Maxconsole Forums
I have permission to use it. But, I personally did not make it.


I got a few PM's asking if this can be done and if so how did I do it? Yes it works as my Slim PSP is now running on M33 3.71 and I love it. This was also upgraded on Sony Official firmware 3.6, not sure if it will work if you updated to Sony official 3.71.



First make your pandora battery without Phat PSP.

For full tutorial/how it works and credit to whom discovered this go here:

BenHeck Forums

I went to WalMart and purchased a 3.6v 2200mAh battery (since this is the only one they had) about 37 bucks. First open the battery with small flat head screw driver by prying around the battery to snap it open. Becareful around the end that makes contact in the PSP as its directly connected to the pcb board on top of battery.



The top part of the battery should come off, take your time to make sure not to damage pcb at top and battery cells inside.



The newer batteries and the 2200mAh has a smaller pcb at the top then the forum at benheck forums depict but it has the same chip that needs to be altered. It has a C04 printed next to it on the pcb. I heated mine up with a soldering iron then lifted it with a tip of a razor blade, then removed it completely from the ic chip as I dont intend to use it as a normal battery. You may solder the leg back and use it as normal battery if you wish.



The battery is now a Pandora Battery (click BenHeck link for info on how it works). To verify this just pop it into slim psp without memory stick and see if power lights up green if so its working.

Also, see the High Resolution Pictures of a Pandora's Battery

Making the Slim Magic Memory Stick

I used the Sony Pro Duo 1gig stick that came with my Daxter pack. You can use any Pro Duo as long as its under 4 gig, 256/512/1 gigs work great. I won't go into detail on fake Pro-Duo's etc.. just make sure its a genuine pro-duo stick.

You will need to use a Pandora GUI there is a couple out there this is the one I used.

Pandoras GUI 1.5 Thread

I ran the GUI with my Memory Stick reader. If you are doing this with your PSP you will need to remove the stick and reboot the PSP after each step.



Make sure you're on the Pandoras Battery Tab as shown in picture

First load the 1.5 firmware either on your hard drive or download it with direct link in GUI.

Make sure your PSP Memory stick drive letter is selected. Mine was H: but yours might be different. Click PSP/GAME since your psp slim is on standard sony firmware.

Format the Memory Stick with step 1 on GUI.

Copy pandora box files to Memory Stick.

Step 3 on GUI is not required as this runs pandora battery installer on phat psp and you already have a hardware modded battery.

Last write IPL to memory stick. This puts the IPL and makes the memory stick bootable when psp goes into service mode.

Next click on the Slim and Lite tab at top.



Load 3.40 and 3.50 firmware updates. Either from hard drive again or direct downloads.

Stage 1 should be set if you just performed Pandoras Battery tab section. If not make sure the PSP drive letter is set on Pandora Battery tab.

Press the copy files button on stage 2. This copies the m33 3.6 firmware to your memory stick. This will put them in the correct directories and names for you.

Stage 3 you cannot run since you will need a phat psp to copy these required files over. This is what had me stumped for a while. When I tried to boot the psp with the memory stick made with this GUI and the pandora battery it would go green but the memory stick would not be accessed. You will need to get the kd and registry directories from someone who has made a Slim magic memory stick. I asked around and got these and this was what was missing, I am sure if you 'google' or ask nicely someone will send these too you.

Update: Kd and Registry Files courtesy of Mexi_chino.



These are the necessary .prx .dregs etc.. that need to be accessed on boot up. The GUIs do not create these, I tried a few other GUIs as well none of them did. After I just copied these to the root of my memory stick, I replaced the pandora battery in the slim and WHOLA the memory stick was accessed and the psp shut down after a few seconds. You will not see anything on your screen as the 1.5 kernel does not display on new slim screen. The only way you can tell its working is orange MS access light and green light turning off. Then its safe to replace your battery with a standard one and reboot psp.

Enjoy your home brew. This is my first attempt to describe how to get this working so there may be parts I need to edit to describe better, but it drove me nuts for 8 hours to figure how to get a slim flashed with M33 firmware without a Phat PSP. With the hardware mod battery, it was now possible to flash without a Phat psp with just a few files and programs.

Okay.....I am very new to psp modding....and this is my first time sauldering as well.

I got to the part where it says "I ran the GUI with my Memory Stick reader. If you are doing this with your PSP you will need to remove the stick and reboot the PSP after each step." and i am not sure what the "Memory Stick Reader" is....and i am also not sure which battery i am suppose to be using when i use the GUI. I have everything infront of me now....and would LOVE some assistance.....if we could talk over IM that would help even more. Looking forward to hearing from you. Thanks!

Can you upload all the programs need to do this setup? I can't seem to find all the files that you've mention. So, can u attach the file in your post. than

[MCMustang51]

yes all files posted would make this thread better

[flitch]

this is so gd
ok now i know the pandora batt, but can i just use a 32mb/64mb memory stick for this?

[Chriscyco30]

64 might work... is it a pro duo?

[Pirate-M.Lifnen]

Updates: Added link to the high resolution pictures of a PB.
And, Added link to Kd and Registry files.

[flitch]

yes chriscyco30, it is pro duo

I have been trying this, but my battery looks different. Here is a picture of it:



In this case, which 'thingy' do I have to cut/modify?

I'd be very gratefull if anyone could help me with this.

It's a Datel Max Battery btw.

I'm getting a PSP soon and all of this complicated stuff is a little intimidating lol but thanks for this guide! I was afraid I couldn't mod a slim as I don't know anyone who's modded a PSP.

Just one question so far concerning the slim magic memory stick: it is only required to install the firmware, right? Meaning, I can just get a cheap stick to do this installation and afterwards use a 4 GB stick for my games and stuff?

Oh and also, I have never soldered before and as such I have no soldering tools. Would it be easy to just cut the leg using an exacto knife or something? Thanks.

hi guys im probably being a total noob here but iv followed this tutorial to the letter and when i boot up my psp with the memory stick and pandors battery i get ultimate loader preboot menu come up on the screen saying that the kd folders on my MC are for 3.52m33 and not 3.71m33 any help is realy appreciated thanks guys

dont bother with this thread its poo. doesnt work dont know why someone would post this very cruel. altho there is a way to do it

[Pirate-M.Lifnen]

Don't double post.

But, it does work, I can assure you, and I'm sure plenty of the people who've successfully followed the guide can attest to that fact.
If you can't figure it out, I'm sorry. I thought that this guide was clear enough, and well made. I apologize for your incompetence.
You might want to look around for another guide or something then.

your so true
