Thanks for the guide Kaiser, worked a treat!
Only difference for me was that the PSP didnt perform the 'lengthy restart' when the 1.5 update failed at 99%, it just sat there for a while and i hard restarted it.

BaH: Happy now-1.5 user :)

I have a PSP v2.01, would I have to upgrade to 2.5/6 then downgrade in order to run emulators on my PSP? Or is there a way to run emulators and ROMs without upgrading/ downgrading.

there is a way to run them, just use eloader and copy of an unpatched GTA:LCS :)
or you can just update then downgrade, either way you need the eloader and the GTA game

To save me buying GTA:LCS couldn't I just upgrade to version 2.50 or 2.60 then downgrade to 1.50?

No, the GTA save-file exploit is the only means of running unsigned code on higher firmwares at the moment, so it's required to enable you to run the downgrading program.

If your downgrading you'll only need it once, so if you have no interest in the game just borrow it from a friend/hire it.

Sorry you need GTA for the 2.5/2.6 downgrader, so you will have to rent or borrow it.

S-B just wait a bit, looks like we're going to have a no-gta-needed downgrader very soon :)

I forgot to plug it into the ac adapter, it told me I had to to update, so I did, hit O, and now it's frozen at a screen that says psp system software 1.50, but no progress bar or failure at 99%. The index.dat.bak was there and I had the 1.5 eboot in place.

The little wavy lines are moving, but that's it. I'm freaking out. I just bought this thing yesterday......I feel like such a noob.

[EDIT]
Okay,

It's ok.

wooh

Oh, i've just bought a PSP v. 2.0 and i want to downgrade it to 1.5. I make all the things like in the first post, i enter the photo menu, that program starts and then my psp go off. i wait 15 secs and i power it on. Then i go to the game menu and when i enter the update to the 1.5 version it says " The system software on your psp system is version 2.00. There is no need to update." What can i do? I have only the pro evolution soccer 5. Do i need gta liberty city ?

Some antivirus apps pick up the downgrader as a trojan because around the same time there was a fake downgrader that used the same exploit and bricked psps.

I used the download from this thread and had no issues whatsoever so rest assured you can use it without fear of it being a trojan.

If you get the 1.5 firmware via this guide's link, a txt file in the archive says 1.5 update japanese, its all english and works fine.

I upgraded to 2.0 and downgraded back to 1.5 TONS of times! The chance of bricking if you do it properly, are sooooooooooo slim, it isn;t even worth counting :)

Hello but help

Every time i download a game and save it to my psp the psp says its corrupt, though it recognises it because it says the name of the game and gives me picture but it doesn't run.

Your anti-virus software is deleting it because it is labelled by Sony as a trojan. Disable your antivirus and download again.
January 22nd, 2007, 09:26

i don't even kno if i have anti-virus software. and it's not deleting it, cuz when i hook up to the computer, it still shows on my comp that the file is there. the file just doesn't appear on my psp under the photo section. weird?
