OK I'm stuck. I've run the downgrader but now my PSP just has a screen saying PSP System Software Version 1.50. It's been like that for about 20 mins now and I cant turn it off. Should I take the battery out or will that ruin my PSP completly. Oh god I'm begining to regret this. :mad: :mad: :mad: :mad: :mad:
heyOKE
I don't know for sure, but from the other posts about the downgrader it says that your psp is completely reset.
I'd imagine that you would have to reset the language to Italian once you have restarted after the downgrade.
Can anyone confirm?
Ok its now working.
But does anyone know of any emulators that work with 1.5? cause I've tried several Megadrive and SNES ones but it say the game could not be started 80020001
MrEverton - Glad to hear you haven't got a brick mate. Anyway, which emulators are you using? Have you tried PSPGenesis for the megadrive?
Are any other homebrew apps working? Try loading the UMD emulator that posted earlier on this thread and see if it starts. At least then you will know if your downgrade has worked for sure.
By the way, what happened after you waited for the downgrader to finish? Did it just take that long or did you shut it down and reboot?
PS. As a fellow Evertonian I'm praying for a bigger miracle for Thursday that having a downgrader!
you got to use the kxploit trick on 1.5 remember.
Please guys help!
I dont know if i should do it or not.
The instructions look very confusing and im worried if ill stuff up.
I have an Australian psp, do u think it will work or stuff?
Help im really nervous!
This is great!!! I have 1.5 so it doesn't affect me but it's great that so many people can enjoy homebrew now.
I have seen it work on an Australian PSP... go for it... you won't regret it.Quote:

once downgraded can u delete the update file?
yepo
Yes u can delete it. also the .bin stuff and the .tiff image.
I had 2 Points where i thought i bricked "it" :
1. After nothin happend after the overflow (after 5 Min with off-powered screenlight) -> Resolution: get off the battery
2. After the "Upgrade failed" screen. I waited 5 Min, the get off the battery again.
"Reboot" *switchin on again, bluescreen, 1.50. Im fine with playin Mega Man1, thanks :D
@heyOKE
You will stay at your foreign language when u downlgrade. I also still have mine :D
Edit: Bah. Too slow typing..
Same happend here!Man i thought i bricked but everything worked ok in the end
with the battery trick. :)
i have a USA psp that i bought on the first day it came out, with firmware 1.0. I bought a game that told me i needed to upgrade to 1.5.2 to play and like an idiot i went and did it, thinking all 1.5.x still took homebrew. i kicked myself after..
Now I have a chance to go back, this is great news, thanks to u guys who managed this.
has anyone made this work with a USA PSP? im so scared, i dont want to end up with a "brick" :( we should have a poll or something that shows how many people this worked for and how many people ended up with a brick. so far, everyone i read, even those who had problems initially, have ended up with it working which is brilliant!
someone brought up an interesting point to me: has anyone tried reupgrading to 2.0 after using the downgrader?
Lets say further down the line after using this downgrader,we would like to upgrade again to 2.0 for some reason (like for example if 2.0 one day would support homebrew or whatever) , but when we tried then it didnt work because of the way we downgraded. there would be a lot of unhappy people on this forum..
Is this a valid question or am I just being paranoid? I guess Im just really concerned about doing this and Im thinking about all the "what-ifs"..
Well I answer my own question: YES it works fine with Ceramic White PSP.
Here is some proof (video playing Snes9x-TYL 0.2c and high def pictures) :

Feel free to use them.
Yeah I can confirm this :) I live in CallyQuote:
echel0n someone brought up an interesting point to me: has anyone tried reupgrading to 2.0 after using the downgrader?
I actually run the 2.0 exploit twice just to be sure that the index.bin.bat file actually appears -
press down quickly after you enter the photo option in your PSP (the second time you run the overflow eploit) and you should see a black screen with some numbers on the left side (if you see this you know its ok to run the 1.5 eboot on the next restart)
I've up and downgraded like 5 times so far ;)

why did it say "X Back" on the video? shouldn't it say "O Back" like on mine?
Poll: Downgrader bricks!
Downgrader did not brick: about 100,000
Downgrader did brick: about 0
There you have it. Of course, you are all going to hate me now, but who cares! So far there have been no reports of PSP bricking due to the downgrader. Eh-O.K.
jaja :p
i hope thats the way it goes :rolleyes:Quote:

But anyway, here's a couple of screenshots showing off some SNES action. I'm so glad I can finally do this. :D
WOOT!
WOOT2!
I dunno. It is a japanese PSP, maybe that's it. On my black "normal" PSP with 1.50, japanese too it is X Back too.Quote:

when i try o launch a game i have the 80020001 error message
do u have any idea ???PLZ!!!!!!! :D
Ok... I tried once... said battery was too low to do it.
Took battery out... put AC adapter in.
Still gave me the "battery is too low" message.
Charged battery to 100% kept ac adapter in with battery after charging... it finally worked.
Said upgrade failed when it was done. Did a cold reboot. Came up fine and and I had to set all of my settings again like time, date, nickname, as if I took it out of the box and it were 1.5.
I did this test on a new Japan White 2.0 PSP.
I already own a black 1.5 US PSP. I need to sell it now. Me and my impulse buying.
This might be a noob question, and this might have already been addressed under this topic but I didn't see it
My only concern is that the 1.50 EBOOT.PBP that I have under the readme.txt states its the Japanese version. Now will this create region problems when trying to play American UMD movies?
The first part of the second question can be answered with just a yes or no - is there an American dump of the 1.50 firmware, and does it even matter.
As the Rock would say... it doesn't matter what kind of PSP you use the downgrader on!
There are no region problems... no language problems... you can reupgrade back to 2.0 if you feel like then back down to 1.5 if you want.
You can use a wab version changer in your 1.5 to fool it into thinking its 1.52... 2.0 or whatever so you can play games like Madden 2006 while using a 1.5 firmware psp which mean you get to play homebrew and decent and new psp games as well.
I wish I would have found all of this before I went and bought a White PSP. Its cool though... I just have to find a way to sell my old 1.5 black psp.
The PSP was released in the USA with the 1.50 firmware. The only 1.50 update that exist is for the JAP PSP v1.0. So no there should not be a 1.50 update in US or EUR version. But I don't know what is the problem with that. If the botton switch is bothering you, you can change it. And that is the only difference.
As far as I know the region isn't stored in the firmware.
Downgraded and it seems to be working fine, but no homebrew apps will work on it, or will work but very strangely. JPEG Viewer was what I wanted but it crashes as the cache skyrockets and doesn't look right at all.
I upgraded and downgraded again, still the same problem. What am I doing wrong?
I guess you can't play new games on the downgraded version? If you can, then It's gonna rock!
weird how mine downgraded, cant remember even putting firmware 1.5 on it.. but after it came on a black screen with numbers i panic'd then when to system to find this

cirus...thats the downgrade exploit, which changes some values and makes your psp *think* its a 1.00, but its still completely a 2.00
however, this gives you the option to run the 1.5 update file to *upgrade* your psp from the 1.00 version it thinks it is to 1.5, while it is really downgrading
and to all those having trouble playing homebrew on a 1.5, go to a "Playing Homebrew on a 1.5 PSP" FAQ, it will explain how to use the kxploit program (though i recommend getting Seipsp tools, PSPbrew, etc) to convert the eboots to run homebrew on a 1.5.
its not the downgrader that doesnt let you play it, you just need to know how to play homebrew on a 1.5
uh, no US PSP came with 1.0. i bought it release day and it was 1.5... :PQuote:

Of course you can.. you just need to use one of the Version changers (WAB or MHP) to change your version number back to 2.00Quote:

Yes
for all new 1.50 users you will need to
Use (SeiPSPTool.exe) or (KXploit Tool )
To put youe emulators on your pSP If not you will get a "Game could not start" warning
Search this forum for the word (pre made emulators) and you can find them already made and ready to use in 1.50

After that you can play ANYTHING!
Here goes a N00B question; Where I can get the 1.5 eBoot?
Edit; Please, forget it?
