How to uninstall a CUSTOM FIRMWIRE from your psp and install a OFFICIAL 1.5 firmwire.

Step 2 ...and now... the procedure,,,

1. Back up all your data on your memory stick as you will be formatting it.

2.Format your memory stick.

3.If you have not downloaded the file from the "what you need step", download it and extract it using win rar.(oh yeah.....install winrar first) =P

4.Connect your psp by going into USB mode.

5.Put the recovery folder into PSP/GAME/

6.Exit USB mode.

7.Completely shut down your psp by holding down the power button or removing the battery (make sure you are NOT going into sleep mode)

8.Press and hold down the right shoulder button while powering on the psp. you will be prompted with a flash screen (recovery mode ,main menu)

9.Select the option that reads Run program at PSP/GAME/RECOVERY/EBOOT.PBP

10.Follow the options as is. "X" to start " "R" to cancel. When done, manually restart the psp by completely shutting down again. Do this by holding down the power button.

11.When powering back on, you will see a blue error screen with lots of words in different languages on it. keep tapping "O" and you will be prompted with the default setup as you did when you first got your psp.

12.That's it your done. I hope this instructable was useful to anyone. Even just one person because then, it was worth writing.

it did not work so if it does not work for me then it wont work with anybody else good luck for next time you create something else.

i have the same problem... i turn it on and its just a black screen...... and it turns itself off after a minute..... what is this? it needs to be fixed.....

[hingino]

mine did the same thing....now my battery doesnt even work, but it happened right after i put costume fimware on it. it completely fried my battery. all you need to do is start your psp with the charger and no battery in it. once you see the whole menu, you put your battery in.

[psphacker]

brick just make a mms and pandora batt

[y8ycgl]

umm... huh?

[hackerlife]

What happened is... well... I don't know, But somewhere in your downgrade process you messed up. Go and buy a second battery (it might have to be a specific type of battery, I dont know) and install DarkAlex's programs and put them on another (small) memory stick. You wanna make whats called a Pandora battery and Magic Memory stick.

[AngusNotSoYoung]

is it worth my hastle to do because this psp that i have that has this problem isn't in that great of condition so if this is gonna cost me like $100 dollars to do i might as well just buy a used psp that's working. how much do you estimate this will cost?

[hackerlife]

OK well heres what it its you can do this with your current battery and current memory stick, but you'd need to backup your memory stick and its kinda a hassle turning your battery into and not into a memory stick. you only need like a 64mb stick, and a second battery would cost you tho. Do you really want to go back to official firmware? There are really no downsides to custom firmware...

[hingino]

you can get a pndoras battery already done for $10 on the internet, and it isnt like some kid is sitting around making pandoras batteries to sell on ebay. it is legit

[AngusNotSoYoung]

well it doesn't really matter to me which firmware i'm on i just want the psp to work. if custom firmware would be easier/cheaper/better then i'll do that. what exactly do you need a second battery for?

[hackerlife]

I say you just go to custom fiirmware, it has no downsides, and allows you to do much more. the seconde battery isn't really necessary, you would otherwise just turn your existing battery into a pandora's. but if your psp isnt working, you cant really make a pandoras (well you could, but it would involve taking apart the battery and de-soldering crap, so no.) so you would have to use a friends psp.

Hey something isnt working here mind helping me out? i put the recovery file into PSP/GAME/ and then when i ran it it said the game could not be started. Then i went into configuration and changed it to no umd and took out any game i had in it it still said the game could not be started what should i do? Thx in advance ^^ (btw i have CFW 5.00 M33 and a psp phat idk if t helps tho >.<)

[Partisan]

I'd just like to say a massive thankyou to the author of this instructable. I bought a used PSP only to find it has Custom Firmware on it, disabling me from using brand new games because I couldn't update the Firmware with Sony. I searched the net long and hard, like literally a few hours until I came across this. It worked perfectly, and now I can play the new games. Thanks alot to the owner! R.Smith

[pancho del rancho]

foo u could have got a newer custom version and free games

[guyman543]

when i try and run the file my screen goes black when i restart the system it comes on like normal with the old custom firmware

[Jabracada]

Well my PSP was semi-bricked b4, at least i could use it. Now thanks to this guide it's completely bricked. Thank's a lot. How can i stick to the "be nice" policy on my first post when my psp is now ruined.

[entar925]

it says the game could not be started 8002013C when I run recovery :P btw its a fat psp with firmware 5.00-m33-4 etc

[crazydaizy1130]

i did everything again, im about ready to pull my hair out, not sure, maybe im doing something wrong. any suggestions

[crazydaizy1130]

well i went step by step i get an error game could not start(80010002)any suggestions what to do now thank u

[scorpio_1945]

power on psp, press select & a menu should appear,scroll down to umd iso mode press left or right arrows on psp d pad & change to m33 driver (assuming that it is the m33 your using scroll down to exit & press x should now work if you can't do this then put any umd disc in & your game will work

[AngusNotSoYoung]

I got a free PSP because my cousin accidentally deleted all the software off it and he gave it to me to see if I could fix it. Well anyway, would this work to reinstall the original software (Or any, I just want to play games) back onto it? If not, do you know how?

[hackerlife]

No, to fix that you'd need a Pandora's Battery and Magic Mem stick. ...which would downgrade you to 1.5, accomplishing this instructable's point.

[damion21]

Yay it worked, thnx for the info.

[sourpatchkid08]

i have the new red god of war psp (slim) and i let my friend convince me into getting custom firmware, but now i think it sucks. i tried wat u sed and it always shows up "unable to startup game (8012383blablabla)" do u kno wat im doing wrong?

[Seraph92]

hey i got a fix to your problem, that is if you did not already solve it. what you have to do is press the select button while in the XMB/Loader screen to bring up the VSH menu and change the "UMD mode" to "NO-UMD". normally you have to have a game inserted to play homebrew, this enables you to play without a UMD inserted. hope i could be of any help. if you have any other questions PM me

[danielsdesk]

I'm not sure what the fuss was about... this worked perfectly fine for me! Thanks a lot! Maybe we should mention what kinds of psps these directions are or aren't working on? For instance, mine is a really really old "fat" psp (not the newer slim psps, nor the newest of the "fat" ones); it's model is definitely fro the PSP1001 series, and this worked perfect for me. Maybe people are having problems doing these directions on newer psps? Also, the custom firmware I had on before I did these directions were the 3.52-M33-4 custom firmware and have now downgraded to 1.5 successfully.

[drammons]

This didn't work. Now my PSP is bricked in the worst way (no screen). The console said PANIC several times before writing files. Now I get nothing.

[Dr_Brechtonio]

Hey, What do you mean with the right shoulder button is that like the R button? cause I can't get it to work Thanx

[alex-sharetskiy]

yes it is

[SSMatey]

You my friend are the man, it worked great thanks alot.

[kish]

[mainlinx]
