PSP V2.0 to v1.5 Downgrade guide

[S-B]

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

Oh awesome, thanks alot for the help.

[M!ckeY]

no problem

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

Yes, i have a guide on how to downgrade from 2.5/2.6 in the cheats and guide section, check it out

[S-B]

No, I meantt is there any way for me to upgrade to firmware 2.60 and then downgrade to 1.50 without buying GTA:LCS.

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
