PSP Upgrader/Downgrader

Posted by greg

Forum member “Bob Joe” has written a Windows app for complete simplicity when it comes to upgrading and/or downgrading your PSP’s firmware. Over in the forum thread you’ll notice two versions — Lite and Full. While the full version may seem more appealing, it’s quite a hefty download… I suggest using the Lite version — it packages the most recent M33-2 update and is significantly smaller in size. You will however be tasked with the responsibility of downloading the necessary firmware updates; luckily for you, we have them all right here. Other requirements included.

    Maybe kids can flash their own firmware instead of asking us scenesters to do it for them.

    Comment by Ooops!
    2007-08-03 02:13:11

    You can’t do anything with official 3.52 until (if/when) there’s a downgrader released for it.

    Question does the m33-2 work with games like power stone and some of the new games that are comeing out cuz my psps can;t read umds and i need to use no umd insert settings in order to play the games but most don work on my 3.40 oe-a.

    Comment by Can you read
    2007-08-03 00:06:54

    yes, 3.52m33 comes with sony’s own ISO loader, and it has loaded every single game so far ive thrown at it, even the ones OE couldnt…but this is all over the forums, i dont see why you needed to ask here

    Comment by Jonathan
    2007-08-06 23:16:55

    Yeah well geuss what 3.52m33 still doesn’t work with powerstone when i have no umd mode on so i’m still f*cked cuz my psp can’t read umds so i can’t play my favorite game powerstone anymore. bu8t at least it works with brave new story.

    Csta is the biggest moron on this site. Ever since the 28th of July (at least that’s what I’ve seen) he’s been asking for a mother fucking downgrader. DUDE, GET THE FUCK OUTTA HERE !!! It’s your OWN FAULT for upgrading to the OFFICIAL FIRMWARE !

     
     
    Comment by Can you read
    2007-08-03 00:10:06

    CSTA you really need to shut the fuck up already, when a downgrader comes out for 3.51 or higher it will be on the FRONT PAGE, i guarantee it. Just stay at 3.51 for a while, DO NOT update to any more official firmwares.

    AND STOP PLASTERING THIS SHIT ALL ALL OVER THE BOARDS, YOU ARE AN ANNOYING ASS KID, IM SURE YOUR PARENTS LOVE IT, BUT WE DONT

    Comment by Affinity
    2007-08-03 13:05:06

    No, you can’t downgrade 2.82 with this.

    You need to use the GTA-LCS unpatched UMD exploit or the Lumines UMD exploit to downgrade 2.82 ~ 3.50. Both from team N00Bz.

    I appreciate any help… thank you

    Comment by Ash
    2007-08-03 21:39:40

    the only way for downgrade your 3.10 is, first you need upgrade it to a 3.50 because GTA is for 3.03. so you would have to use lumines to downgrade

    I Love how the same questions keep getting asked over and over again. And usually things that are in an FAQ, or one of the many well written manuals that are posted on this very site. Everything is explained really well, you just need to have some common sense, which seems to be on short supply. Thanks for the great addition to the PSP app library, we appreciate anyone who puts their own time and effort into making things easier for others. Thank You!

    P.S. - READ BEFORE YOU ASK QUESTIONS!!!! PLEASE!!!!!

    Hey, guys, I need help

    I tried upgrading from 3.10 OE-A to 3.40 OE-A and didn’t work.

    The first step install the 3.40 OE-A Update Maker. Then I have to run it. The PSP reboots and everything goes all right.

    The second step it installs the 3.40 OE-A Firmware Install. I click on it and it comes with the message “The game could not be started. (8002014C).

    Am I missing anything ? Should I format my Memory Stick ?

    2007-08-04 16:10:34

    So this “upgrader/downgrader” only serves for 1.50 users, OE users and M33 users? So NO 3.5X or TA board users?

    Comment by Ash
    2007-08-04 16:46:29

    i don’t know about if it will work on that specific motherboard but, yes works only with the firmware types you mentiond P.S. if you cant find any answers try reading the readme txt it should help. Ash

    Just a suggestion.

    Instead of “going off” and taking out your frustrations on the people asking questions, why not point everyone to a FAQ or File that would answer the basic questions…What UMDs to have, what numbers to look for, mother boards, models, Firmwares, etc.
    Some people can not afford to mess up their PSP/ with no hope of getting a new one. And buying useless games don’t really appeal either.
    A little patience goes a long way.

    you raise a good point there, and i also understand where your coming from. I’m not the type of person to just flame people but you got to admit, lol it is kind of anoying when people read the comments on this same exact page asking for questions when the answer is infront of them lol. a few comments above,i gave a link and answerd their questions yet people still ask questions thats been already answered more than once. lol thats probably why people get frustrated and start flaming all time.

    Comment by Can you read
    2007-08-05 20:38:55

    Thats the main problem twis, is that everyone wants everything handed to them on a silver platter. What I did, and everyone else should somewhat attempt (not being arrogant here if it comes across that way) is read the forum stickies, manuals, do searches, mainly READ. Do AT LEAST a couple hours of research before trying anything, then if you have a question, ask it in the forums where your supposed to, not on the comment threads for new apps.

    Doing this you will be sure not to fux up your psp, or whatever your modding, ive modded every system i own in this way, and have yet to have a single bricked system, xbox, ps1/2, psp, dreamcast, etc….

    peace

    Stupid questions, do i need lumines 1 or 2 this is just a percaution i feel i need ask, also when you have finally taken all the steps and have your systems firmwere at 3.40 oe-a will this thing turn off the updater, or is that something we have to do ourselves the updater incase i’m unclear is the function where our system says an update is availible

    can you downgrade from official firmware 3.72??

     
    Comment by Picowolf
    2007-11-15 08:02:10

    god dammit, you fucking reatarded monkey fucker, why the fuck can you read the post above you, people keep asking this question, and the fucking answer won’t change,

    NO!!! YOU CAN’T DOWNGRADE UNTILL SOMEONE FINDS OUT HOW, FOR NOW YOU ARE STUCK,

    but since your a fucking retard let me put things this way,

    I’M SORRY YOU CAN NOT LOWER THE SYSTEM’S FIRMWARE AS OF YET.

    i would go ahead and describe each word and try and sound out all the the pretty sounds, but i fear my efforts would be wasted on that vacant head of yours.

    so i’ll just tell you what you want to hear because you won’t bother readying the 4 or 5 replys to the same questing.

    yes it is possiable to downgrade your firmware from official 3.72.
    first you need to grab your PSP, make sure the battery is charged above 89 percent any thing less this hack won’t work. now plug it into your plug it into your computer via a usb cable. for information on the proper usb go to http://www.youplusdieequalswin.com they have good usb cord thier for only 7.99 USD if you need one.
    As soon as you connect your PSP to your Computer you pour water directly on your mother board. the resulting energy surge will downgrade your PSP and your computer and maybe your whole house, to the most basic Firmware. rubble and ash. what better way to downgrade your PSP then by starting a fucking in your house. and not only that, we will all get the pleasure of know another child who never learned how to read has been wiped from the face of thier earth. no longer able to spead his unwanted seed via date rape.

    i hope you find this helpful gomdon, kat,csta, and Alex.

    hope it all goes well for you. have a great day. ^^
