3.50 Downgrade Guide

[x3sphere]

Only post questions related to the downgrader here.

Requirements

Lumines UMD disc (JP, EU, or US version)
3.50 Downgrader Files (http://exophase.com/files/psp/Downgrader350_All_Unpatched.zip)
1.50 Update EBOOT (http://exophase.com/files/psp/150.PBP)
3.50 Update EBOOT (http://exophase.com/files/psp/350.PBP)


Upgrading Instructions (if you are not yet on Firmware 3.50)
1. Download the 3.5 Update (http://exophase.com/files/psp/350.PBP).
2. Save the file as "EBOOT.PBP" and place it in X:/PSP/GAME/UPDATE. If the directory doesn't exist, create it.
1530
3. On the PSP, run the 3.50 update from the memory stick under the Game menu.
1529
4. Once the update is finished installing, delete the UPDATE folder.
1527


Downgrading Instructions
1. Copy the PSP folder from the 3.50 downgrader ZIP (http://exophase.com/files/psp/Downgrader350_All_Unpatched.zip) to the memory stick. It's located inside of MS_ROOT.
1528
2. Download the 1.50 update (http://exophase.com/files/psp/150.PBP). Ensure that it is named UPDATE.PBP and copy it to X:/PSP/GAME/UPDATE - DO NOT OVERWRITE PSP/GAME/UPDATE/EBOOT.PBP!
1526
3. Load Lumines and press X to start the game.
1525
4. The screen will clear to black and fill with a light blue color, then the PSP will return back to the XMB. If not, try again.
5. Check that HEN is running by going to system settings, then to "System Information" and it should show up as system version 350 HEN.
6. If it is showing up as HEN then go to the Game menu and run the X.YZ update.
1524
7. If you have an unpatched TA-082 or higher motherboard, you will be prompted to allow the downgrader to patch your motherboard so it can be safely downgraded. The downgrader will not let you proceed without patching, if your motherboard requires it.
8. Before the downgrader does anything to your PSP it will ask for you to agree to what it is doing, if you no longer want to continue press the R button.
9. Once you have agreed to start the downgrade do not unplug the PSP, or try and restart it.
10. Once finished the PSP will ask you to press X, and reset itself.
11. If it comes up saying that the settings are corrupt, press X to continue, this means you will need to re-enter the settings for network connections into your PSP, otherwise go to step 13.
12. Load the included NetConfigBackup application in your PSP, and select to restore, this will take the backup that was done of the network config that was done automatically during the downgrade.
13. You're finished! If all went well, you should now be on firmware 1.50!

yeah - why wouldn't it be? Noobz released a 3.50 downgrader today.

I totally second and THIRD that! (cause i can't double post).
just out of curiousity can it downgrade fw 3.10~3.40? or will it jsut brick the psp due to some authority, keys, ip, etc problems:confused1:

no, the downgrader is written specifically for 3.50, don't try it on other firmwares. If you are on 3.10 - 3.40 just upgrade to 3.50 then downgrade.

[Pantysniffer]

Is this hurting Sony? UMD has already failed - I hope the PSP isn't going to pull a Dreamcast, 'cos that'd make me a sad panda.

[banner]

Im an uber noob to this and so far i see an error. In step 3, there isnt an "UPDATE" folder within "PSP" so you need to create one

X:/PSP/GAME/UPDATE << create UPDATE folder

[leftyboy]

I heartily apologize for doubting. :sad: :smile:

[banner]

okay step 5 says to delete the UPDATE folder which had the EBOOT.PBP, then step 7 say to not overwrite it. Now is the EBOOT.PBP suppose to be in with UPDATE.PBP???

[Cheezeball99]

Im an uber noob to this and so far i see an error. In step 3, there isnt an "UPDATE" folder within "PSP" so you need to create one

X:/PSP/GAME/UPDATE << create UPDATE folder

Actually, if you put the files from the 3.50 Downgrader onto the memstick it makes the UPDATE folder.

As a sidenote- X3, I think I know why there's not as much traffic as a usual new OE or the etc.- DaX no longer links here. That's how I found this site, actually, from clickin' on the link on DaX's site for 3.03OE-C. You should have him put a link to here, 'For Questions or Help' or something, linkin' here.:smile:

[banner]

okay im confuse on step 7. Is there suppose to be the UPDATE.PBP and EBOOT.PBP in PSP/GAME/UPDATE/ ???????

[x3sphere]

okay im confuse on step 7. Is there suppose to be the UPDATE.PBP and EBOOT.PBP in PSP/GAME/UPDATE/ ???????

well assuming you are following the guide the EBOOT.PBP should already be there. you just need to copy over the UPDATE.PBP

[banner]

I am but in step 5 it says "Once the update is finished installing, delete the UPDATE folder you created in step 3." in the UPDATE folder was the EBOOT.PBP. So do i need to add UPDATE.PBP again?

[banner]

Let me clear this up. Im on version 3.50 and i copy the "MS_ROOT" folder from "Downgrader350.zip" to F: (no subfolders)

[Cheezeball99]

No, copy the contents of the MS_ROOT to the F:\, so in other words copy the PSP folder to the root of your memstick.

[banner]

So copy the folder "PSP" within the "MS_ROOT" to the memory card????

[Cheezeball99]

So copy the folder "PSP" within the "MS_ROOT" to the memory card????

Yes, that is correct.

[banner]

now im overwriting the folders, which are "PSP, GAME and SAVEDATA" i believe

[Cheezeball99]

now im overwriting the folders, which are "PSP, GAME and SAVEDATA" i believe

Then you are on track, that should have happened, it's all fine.:smile:

[banner]

OKAY I MESSED UP!!! THE GAME LOADED LIKE NORMAL!!! :w00t:

[Cheezeball99]

OKAY I MESSED UP!!! THE GAME LOADED LIKE NORMAL!!! :w00t:

Okay, what version of Lumines are you using? You're using the US or EUR version, correct? Also, you made sure you let it overwrite the folders and files in the SAVEDATA folder when you put the PSP folder on the memstick, right?

[banner]

okay, nothing happen :sad:

[banner]

US version

[banner]

the game loads to the main menu but when i press start to play the game it goes back out to the game icon (sonys menu)

[Cheezeball99]

Then go to your 'System Settings'>'System Information' and check if you are running 3.50HEN

[x3sphere]

You didn't copy over the files correctly. You need to copy the PSP folder to your memory stick, and make sure if it asks you to overwrite any files you choose "Yes to all"

And you did copy over the UPDATE.PBP as well right ?

[banner]

Cheezeball99- yes, it goes to the main menu to where it says 'press start' on the bottom
x3sphere- yes i did that

[banner]

im looking at it right now and UPDATE.PBP is copy it to X:/PSP/GAME/UPDATE...after i copy the "PSP" folder over..in which it overwrites about 3 folders

[Cheezeball99]

Then go to your 'System Settings'>'System Information' and check if you are running 3.50HEN, maybe you are. I'm sorry I'm not as knowledgable, but I haven't actually done this, for I do not have a copy of Lumines.

[banner]

the battery is charged and the firmware is 3.50 HEN within the system information

[Cheezeball99]

ROCKIN'! Now run the PSP Update ver X.YZ under the Game menu

[x3sphere]

the battery is charged and the firmware is 3.50 HEN within the system information

so - it worked then. Continue on with the guide.

[banner]

it doesnt do anything, it just goes back to psp menu

[banner]

THE UPDATE LINK HERE GOES TO SONY'S OFFICIAL UPDATE PAGE. MAYBE ITS ALREADY PATCHED??????????????? :sneaky2:

[banner]

8. Load Lumines and press X to start the game.
9. The screen will clear to black and fill with a light blue colour, then the PSP will reset itself.

this never happened. I turned off the psp because it went back to the psp menu

[x3sphere]

If you ran the Update X.YZ program, it wouldn't just go back to the PSP menu. Secondly, Sony does not change the firmware updates on their pages.

So, it has to be giving you some error.

[Cheezeball99]

Yes, but you ARE running HEN, which is what loading Lumines accomplished. You don't go to Network Update, you go to your 'Game' folder and there should be PSP Update ver X.YZ just like in the picture.

[banner]

okay, i just click on "PSP Update ver X.YZ" and wait a while for a screen, which is black in the backgroud with little pink fonts, saying


"Update Flasher by Dark_AleX/Noobz.
PSAR extraction code from psardumper (by PspPet).

You are about to flash your PSP.
Press X to start. By Doing so.." sorry thats all i can type down before the huge pink "START" popped up. I then press X to restart.

[banner]

Oh yay, i got it!! it auto loads Lumines when its done restarting. I then exit Lumines and check what version i have and it says (not with a voice, of course) System Version 1.50, but now i have a MAC address which i didnt have before. why?

and its has the purple theme, because of the month.

[Cheezeball99]

Very good, once it's done and you press X to restart it you should be running 1.5! Congrats!

Can't answer about the MAC Address, I dunno. Now you can upgrade to 3.40OE-A, guide HERE (http://forums.exophase.com/showthread.php?t=383), and welcome to the world of PSP homebrew.:smile:

Yes, you've downgraded :) That's normal, the MAC address is displayed in firmware 1.5.

Follow the first guide. You don't need Devhook if you have custom firmware.:biggrin: I would suggest formatting your memstick now AND after you upgrade to the latest OE.

You really don't need Devhook if you're installing the custom firmware.

Also, yes, you should format your memory stick.

[banner]

even if there is .CSO files?

[x3sphere]

even if there is .CSO files?

What do you mean by that? Yeah OE firmware supports both ISO and CSO files.

[Cheezeball99]

Yes, the custom firmware works with ISO and CSO files.

[banner]

Dont you guys think its easier for noobz (< get it??) like me to downgrade with one easy folder?

Let's say if you take out the PSP folder in Downgrader350 (after extracted) and put in the UPDATE.php within that folder to PSP/GAME/UPDATE and zip it up as one file. It'll be easier.

My steps if it was like that

1. Extract "PSP.zip"
2. copy and overwrite the first PSP folder in your memory stick
3. Load Lumines, click start and it will go back to the main psp menu
4. Restart your PSP
5. check version, it should be 3.50 HEN
6. Go to the game menu, hit Update X.YZ
7. Hit "X" to flash
8. press "Start" when it says "Start"

:smile:

[Cheezeball99]

No, because the file is being distributed as it was intended by the Noobz team, plus in your 'noob' instructions you said nothing about actually picking the Update X.YZ.

[banner]

oh..i forgot. It wasnt an official guide and im also trying to figure out the 3.40 OE-A installion. Im lost after step 3.

Go over there and help me out if i run into any noob problems, will ya.

[banner]

WOW, thats about 60 pages long!! ill try my best to get through it. So far i have a "Corrupted Data" above "3.40 OE-A Update Maker" after i copy the 2 .PBP over.

[banner]

The corrupted data doesn't mean anything. just click on update maker


toke awhile, but i read this

[banner]

I followed all you direction and every time i go to my memory sick on my psp.I see 2 corrupted data and the 3.40oea update make and firmware installer. every time i click on the update maker my screen goes black and nothing happens and it eventually turns off. PLEASE HELP ME!!!

i have the same problem as this guy


sounds like a memory stick problem. first I would try formatting the memory stick (on the PSP) then copy the files back over and see if it works.

if that still doesn't work try a different memory stick.

nope not memory card problems to me, mine is brand new fresh out of the box.

[banner]

Okay for you noobz out there. The whole point of the 3.40 OE-A Install Guide is that each installation has 2 folders the first is "oeupdmaker" and the second is "340oeflasher" [their second folder is the same name but with %]. You need to install oeupdmaker first before you began to install 340oeflasher because by installing oeupdmaker 3.40 (OE-A Update Maker) it creates a file that 340oeflasher (3.40 OE-A Firmware Install) needs to work.

And i had a porblem with installing 3.40 OE-A. when it restarts it goes to a weird mulit-language screen; i just hit the O botton and it shuts down, after that i turned it on and it went to default mode.......after configuring my settings, i check what firmware..then BOOM 3.40 OE-A!!

[banner]

Okay ive tried my best to help the future noobz out there, which there's going to be a whole lot of because of Lumines. So Admit and Cheezeball yall can rest.

[x3sphere]

Congrats :) Nice to hear that 3.40 OE-A is now installed.

[Cheezeball99]

Indeed, congrats. Sorry I didn't help ya for the last hour or so, I had to run an errand. Glad to see you worked yourself through it, though.:smile:

Programs, as in homebrew? You need to place the folder containing an EBOOT.PBP in GAME150

For example... let's say you are installing an NES emulator. The folder path would be like this:

X:/PSP/GAME150/NES

The folder NES would contain the files necessary to run the program (EBOOT.PBP, etc)

[banner]

Thank you very much Cheezeball99 and x3sphere its nice to know you 2 work for Nintendo. :w00t:


As for my lastest error "The Game could not be started 80020321" the solution is simple. PUT BACK IN LUMINES OR A UMD!!

no, not a homebrew :wink: you know what i mean by "PROGRAM" :biggrin:



any way to make it work without a UMD?

[Cheezeball99]

No, you have to have a UMD for almost all stuff to work, and it has to be a game UMD. Plus, if you're referring to what I think you're referring to, we don't support piracy. sorry- If you were referring to something else I apologize, but I'm pretty sure you were.

Hey is there a large or small risk of bricking your psp.
I go to boot lumines and it doesn't go black then light blue it just makes a new save file I got my lumines in Australia don't know whether you need a certain version of lumines but it doesn't have a patch update on it help much apprecited.

so the game just started as normal? system information still says 3.50 and not 3.50 HEN?

maybe the Australian version has a different Save ID. can you list the folder names of any Lumines saves in X:/PSP/SAVEDATA ?

If it has a different Save ID then it is definitely not compatible.

[Death_Pigeon]

Nvm i forgot to take it out of the Mp_root folderrand place it in PSP
But it went to a blaack screen i know its still working because the sound is on any help.

EDIT: Sry went throught forums all you had to do was press the back screen light button.

BTW: the first picture of the Downgrading Instructions is very helpful. Thats where Death_Pigeon and I got confused. When he says "contents on the folder" he mean "contents in the folder" which is only the "PSP" folder.

[`Rage`]

Hm... Just a few questions.

My PSP is the first model, got it right when PSP's came out a few years ago, would there be any problem downgrading with the motherboard that's in it now?

And also, is there a great chance of bricking? Cause my warranty is definitely up.

Thanks.

I also got mine on release date, worked just fine for me.

You don't have to worry about your MoBo, all models work. But the bricking- there's ALWAYS a chance of bricking, but that chance is probably somewhere around .001%.

is a copy of the lumines included in the 3.50 firmware version. Also when downgrading from 3.5 to 1.5 ,do we copy the contents of the MS_root of the 3.5 downgrader zip to the MS_root or game folder on the psp

contents means inside the folder, and the PSP folder is inside of MS_ROOT, so you copy the PSP folder.

You need either an EU or US copy of Lumines UMD disc.

how could a UMD disc be included in the zip file ? o_O

you need to buy the Lumines game.

EU = Europe
US = United States

check local stores for it or http://amazon.com

[Rainwolf]

So, I started this process, damn sure I had 3.50, but when the lumines thing wasn't working I went and checked and somehow I have 3.51, so now I'm wondering, is this process incompatible with that, and if so, any known 3.51 downgrade process?

[Cheezeball99]

Yeah, buddy, you're boned. Sorry. No DG for 3.51, in fact, the only difference between 3.50 and 3.51 is Sony's patch to this Lumines exploit.

[Rainwolf]

Those twizzlers!!! Oh well, waiting game I suppose...

[hitman001]

Sup ppl.. i ran into a lil problem....im on 3.10 and when i try to update to 3.50 it says the system configuration of the psp does not appear to be correct....so could someone help me out please id appreciate it....

[Andaz]

Hey can i have lumines game in memory stick so that i can use that game from memory stick for downgrading

[Andaz]

without using umd

[Cheezeball99]

No, if you could run UMDs from the memstick what would be the point of going to an OE firmware? Sorry if that sounded harsh, but no, you HAVE to have the UMD, because the whole point is running the ISO, and you can't do that natively in the official FW.

do u hav any idea how much it costs?

It should cost under 20 USD in most game stores

hey recently i've downloaded psp game (.cso) file frm the internet and i like to play that game in my psp.. where do i need to put that file in order to play that game

[x3sphere]

Sup ppl.. i ran into a lil problem....im on 3.10 and when i try to update to 3.50 it says the system configuration of the psp does not appear to be correct....so could someone help me out please id appreciate it....



N00Bz RoCKs!i!

question: have you ever downgraded your PSP before? If you had previously downgraded to 1.5, then re-upgraded back to 3.10, you are basically stuck on that firmware for the time being. However, Noobz plans to fix this:

Future plans? Firstly, we intend to provide a solution for people who are stuck on firmware 3.10 or 3.11, unable to upgrade to 3.50 due to the new Sony checks. The exact format of that solution is still to be decided. We also intend to develop an eLoader for v3.50 HEN, so that those who do not want to downgrade will still be able to run some homebrew.

Nothing. The root of the PSP is your memory stick drive.

So... if it were H: you'd transfer the files to H:/

Thanks, so do you think a noob like me could do it, you know the downgrade

[gkid007]

SO just to make sure i wont be doing anything wrong.

1.Psp on 3.5
2.get downgrade pack and 1.5 firmware
3.i rename the 1.5 update file from eboot.PBP to UPDATE.PBP
4.i put UPDATE.PBP into the UPDATE folder.
5.i overwrite the PSP folder which is in the MS_Root folder onto the memory stick(OVERWRITE the psp folder already on the memory stick)
6.i run lumines
7.check if its at 3.50HEN
8.then i run update file X.YZ
9.Finished

That's right but step 5 should be above step 3.

After you overwrite the PSP folder with the one from the downgrade pack you copy UPDATE.PBP into the UPDATE folder.

I was just wondering whether this makes the 3.03 downgrade and the 2.80 downgrade obsolete. As in would you just upgrade ANY psp (Below 3.50) to 3.50 than downgrade from there? Or do you recommend upgrading to the closest version of your firmware eg. 2.70 to 2.8 or 2.9 to 3.03 than downgrading. Or there is absolutely no difference. I'm asking this as I'm looking at doing a few friends psp's but there all on different versions so If I could learn just this method that would be great. Thanks in advance.

[supaquickt]

I see you can also do a 2.71 downgrade so my example 2.70 to 2.8 aint quite right, but you get me. I think..

Nah it doesn't make those obsolete. Reason being is because you need Lumines to use it. If someone is on 2.71 and doesn't have Lumines, then they will want to use the 2.71 downgrader.

If you have Lumines, then I'd just suggest upgrading them all to 3.50 and then downgrade to 1.5.

I believe what he means is if he can leave it on 3.50HEN and just run homebrew 'n' such from that, without downgrading. I believe if you completely turn off your PSP and turn it back on then the HEN is gone, correct x3?

Well you don't need to know the motherboard version as the downgrader will automatically detect it.

No if your PSP bricks there is no way to fix it other than getting a modchip. But 99% of the time the downgrader will be successful. You can't rule out hardware issues though.

it means that some times when flashing there would be a hardware crashdown, both temporary or permanently, but the chances is REALLY little. i screwed up my psp this morning and flash from 1.5 to 3.40OE-A between like ten times and my psp is still fine. so it's almost impossible to have a hardware crashdown.

just follow the steps SLOWLY, plug your ac on your psp and you will be fine. after downgrading to 1.5 take your UMD out just in case the game auto starts and auto updates again.(take it out after finishing downgrading and before you open your psp again.)

Hey there i totally respect your guide for downgrading but there is one thing which doesnt work for me and its the 3. Load Lumines and press X to start the game. The screen will clear to black and fill with a light blue color, then the PSP will return back to the XMB. If not, try again. Well my screen didnt turn black and didnt do anything at all just did what its supposed to do i tried it over 50 times still doesnt work... i repeated everystep trying to find mistakes but so far i think i have no mistakes at all any help will be accepted please :confused1:

You don't have the files in the correct place then. Try copying over the PSP folder again.

EDIT: Please don't double post...

[SlayerPsp]

Ok thanx ill try it

[SlayerPsp]

Still didnt work but maybe i understood this instruction wrong ? 2. Download the 1.50 update. Ensure that it is named UPDATE.PBP and copy it to X:/PSP/GAME/UPDATE - DO NOT OVERWRITE PSP/GAME/UPDATE/EBOOT.PBP! Do i place the UPDATE.PBP into /MS_ROOT/PSP/GAME/UPDATE OR into PSP/GAME/UPDATE?

[Acerthief]

ms0:/PSP/GAME/UPDATE.

you don't put the MS_ROOT folder into your ms. go into the MS_ROOT folder, THEN copy all the contents INSIDE the MS_ROOT folder.
i suggest formatting your memory stick and try again.



x3sphere said do not double post. and you did it again. it's going to be a warning if you double post again.

if you posted and you want to add something use the EDIT button on the bottom right of your post and then add in what you want to say. :)

[SlayerPsp]

Hm i formatted it now but it seems that my MS_ROOT is called MP_ROOT on my PSP for some reason. Is that normal and am i double posting again?

[Acerthief]

nope not this time. MS_Root and MP_root has nothing to do with each other
you go in MS_ROOT you'll see a PSP folder right? copy the PSP folder and then overwrite the one in your ms stick.
is this clear? if not i'll think of another way to tell you....:D

I've got a psp running with 3.50.
Now I'm trying to downgrade so I copy the "psp" folder to the memory stick and the renamed Update.PBP to :/PSP/GAME/UPDATE
But when I start Lumines (ULES 00043) it loads the game normally until the situation where I have to press START (or X) now the screen turns black and after about 15sec the psp turns itself off.
No blue flashing, no going back to XMB...
When I turn the power on the psp on it starts as if nothing ever happend and I'm still running 3.50 no 3.50HEN.

Do you guys have any ideas whats going wrong?
I already tried things like formatting the memory stick and starting anew with exactly the same effects.

it just turned itself off

reading your original post, you said your PSP is running 3.10 OE-A? If so, you can skip step 1 of the 3.52 M33 install guide.

1. If you are running firmware 1.5, first go inside the "1.50only" folder and copy both kxploitpatcher and kxploitpatcher% to X:/PSP/GAME and then execute the program through the game menu on the PSP.

Your PSP is not running firmware 1.5, so you can go directly to step 2.

Sorry bro, the lowest a slim can get is 3.60.
and even if you got to 3.50, a slim can't be downgraded to 1.5, because of the hardware difference.

What you can only do is to use the "Universal Unbricker/Installer". Check it out in the FAQ Section :D

Note that you need another PSP with custom firmware to install the memory stick.

will this break my psp in any way if this goes wrong or even right?
also can i then play downloaded ISO games if i downgrade from 3.52 to 1.5



If you just follow up the guide, bricking is almost impossible (0.1% less)
and no, 1.5 can't play ISO, and we DO NOT support downloading ISO games.

Negative mate. That's your only way.

What would happen if i would just not start lumines so skip the lumines points in the guide and go along like it said?

could i try to accomplish runninh HEN with different games?

and im really not one of those guys that just doesnt wanna buy lumines but i just went to target, walmart and two different video renting stores and NONE had lumines...so yeah im kinda desperate now to find a way to get this done w/o lumines if even possible

It wouldn't work at all. HEN takes advantage of a save game exploit specific to Lumines.

[Extrapunkt]

hmm just beeing curious right now...
so how did they find out that lumines accomplishes the exploit? i mean did they just try random games and than suddenly it worked with lumined? O.o

Well, Lumines is one of the best selling PSP games so it makes sense that they chose it first to try and find an exploit. It's likely other games have a similar exploit, but HEN would have to be rewritten for another game.

Do you have a GameStop or EBGames nearby? Should be able to find the original Lumines there.

[Extrapunkt]

Oh okay...
well i found out that a friend has it and she is gonna give it to me tom... i was just waiting so long for my psp to arrive and i read so much about all the downgrades and upgrades to custom firmwares that i was kinda desperate to get it done tonight =)
I keep your updated if i actually get this all done right ^^

Thanks for you help, i really appreciate it =D



EDIT: So yeah came out that her lumines was lumines II ahhh but thats fine i went to a gamestop and after looking in the backroom and pazing 30! bucks i got a lumines copy YAY! I bought Crisis Core too...

And now im running 3.90M33-3 and play crisis core form the stick haha i was really afraid doh when i upgraded to 3.90M33 because it really looked like the standart sonz update but everything is running really nice now.... thanks for all you help =)

I need some help. Ive been reading the forums and praise you guys for your hardwork and input on modding the psp. I already have my own psp with custom firmware 3.90M33 but i have a friend with an official 3.73 firmware on his and he wants me to put custom firmware. Ive read the steps on how to downgrade and its just not working for me. And i dont seem to find steps on how to downgrade from this firmware that he has.


So my question is....Can he downgrade from this firmware? Or is he just stuck with it for now? And since i have a cfw psp. Is there anything i can do with mine to help downgrade his into cfw?


He has a fat psp very early model he has had it for years now. I tried following the steps to make a pandora battery but it wouldnt load the file. It gives me game cannot be started (80020148) so im stuck at this point im still reading the forums but i have found nothing to help me. So if theres a way i can make a pandora battery on this version he has let me know please. It will be greatly appreciated

Can I downgrade my Psp 4.01 to 3.90?

[Snizzoop]

Okay...here's the deal...I have a phat PSP. It had OFW 2.00. I upgraded to 3.50 so I could downgrade to 1.50. I had no problems upgrading, but I have having difficulty downgrading. I have copied the PSP folder from the .ZIP file, and have saved the 1.50 "update" as UPDATE.PBP. I then start Lumines, and the game just loads as normal.

What am I doing wrong?

AAAAAAAAAHHHHH! The insanity!

Amazon, eBay.

No it doesn't work with firmware 4.05... you need to use a Pandora battery / magic memory stick to install CFW on your PSP.
