  • Losers DONT Understand

    http://forums.afterdawn.com/thread_view.cfm/552549
    then after u make the pandora aka jigkick battery put the 390 pbh file from this download instead of the 371 pbh file in has inside (i mean to replace it) and then follow the instructions on the net and execute the file and VIOLA U HAV A psp wad ever slim version (i dunno why the idiotic people put the color of their psp in the comments …) So now u go to the system information menu and see OMGOMGOMG IT SAYS PSP VERSION 3.90 M33!!

  • Mongo

I have currently firmware 3.52M33-3 and that is the minimum needed for the update. Can someone please help me? email: mcornejo01@gmail.com?

  • Mongo

    Ok so I double checked everything and I was able to start the update but it errored out when it was going to start with the error: “The system cannot be updated. The update data is not applicable for this system. (CTA80000025)” Any ideas?

  • Terry

    Here is one for you experts, I bought a slim psp, and i have the official firmware 4.05 from sony. I bought a pandora battery that has a blue led light on it so you can use it as a regular battery and as the pandora battery, supposedly with the push of a button, but heres the problem, I CANT GET THE PANDORA PART TO WORK!! I put in the magic memory stick that has the custom firmware 4.01 m33 on it, that also came with the battery i bought, then after i put in the memory stick, i put in the battery and nothing happens, it wont boot into the service mode where i can install the custom firmware, any ideas???

  • Terry

    Nevermind, I didnt know that the pandora battery had to be practically fully charged to work. I got it working now, thanks anyways.

  • Roxas

    hi, I have a black slim PSP, and I want to know how to get my PS1 games to work on it without having to make a Pandora’s battery or anything like that. I’m not very good with tools. Can someone help me? I have tons of firmwares that I downloaded, and I’m not sure what to use on my slim version. Please help.

  • Terry

    Well, you have to have custom firmware installed to play any of you ps1 games, or any game you download off the internet. The only way to put custom firmware on the slim psp is to use a pandora battery, now you can buy a battery and magic memory stick package for around 40 bucks, or you can find someone to install the custom firmware for you. Now i know its risky, but there are people on ebay that will install custom firmware for you for about 20 bucks. If you are willing to take that rout, i will do it for you for Free, send me an email if your interested . player_x_slayer420@yahoo.com

  • Roxas

    sure. I’m definetly interested. I am a diehard FF7 fan. Heh. They say that you can either buy a battery or have someone “copy” it over from something. I’ve been reading up on this all day, and I am desperate.

    Lol I sent you an email, go ahead and read it, and i will be more than happy to help you out.

  • Stef

    Hey guys
    just got PSP Slim (silver)
    OFW 3.80
    Is there a way to convert it to 3.90 M33 CFW without using a Pandora’s Battery? Plz email/IM me, Crimson_evader@hotmail.com
    any help is greatly appreciated

  • Terry

    Nope, Pandoras battery is the only way to go if you have a slim psp, especially with firmware above 3.50

  • Stef

    damn…
    Cause i will most likely brick my psp if I try make a Pandora…
    mostly due to my complete lack of skill lol

  • Terry

    well, you dont have to make the pandora if you dont want to, you can buy a package with the pandora battery and magic memory stick online for about 40 bucks. usually that gives you a pandora battery and a 1gb memory stick with the needed software to install custom firmware.

  • Avenger

    Hey guys, I have a little doubt…I have a PSP FAT…firmware 3.71 m33-4
    but some games, as “harvest moon innocent life” crash my PSP when I try to play…it just turns off Oo
    I wanna know what can I do…update the firmware maybe?
    and if I do so…can I still play my MS games without a pandora and without an UMD? thanks for complaining
    e-mail: zellavenger@hotmail.com

  • Terry

    Most likely you need to update your firmware, I have the newest version of the 4.01 m33 and i havent found a game that wont work yet. and what do you mean by MS games? there are settings where you can make games play without having a umd in the psp.

  • Avenger

    ms games = games stored on my Memory Stick ^^!

  • http://EnterYourWebsite Terry

    yeah, just visit dark alex’s web site to get the updated firmware, or if you have a wireless connection you can do the update on your psp. i have the 4.01 m33-2 and i have no problems running any iso, cso, or psx game.

    weird peeps

  • Roxas

    I got a friend to mod it for me! It’s osm. Thanks for everything guys. I have my custom Pandora’s Battery and Magic Mem Stick.

    However, are there any known glitches while playing FF8 and FF7?

    When I started up FF7, it goes through the first FMV, but when Cloud goes to battle the first two MPs, it gets all glitchy, freezes, and shuts off.

    When I play FF8, when I casted a spell at Ifrit (scan), it froze and shut off.

    I burnt the BINS from my discs to play? Could it be my discs are messed up. I only downloaded FF9, and it works fine. I’m on disc 2 now. Any input?

  • rishabh

    hi how to download iso folder please help me

  • Roxas

    Are you trying to download a PSX game (iso), or a bunch of isos in a folder?

    And to solve my problem, I believe I have to use a different version of Popstation with FF7 (namely, an earlier version), and that I shouldn’t cast Scan in FF8, and also don’t cast too much magic at one time, or it’ll freeze. I’m gonna try ff8 again.
