PSP Downgrader - Downdate Final Version For v2.50/v2.60 PSP Firmware

[zx-81]

It works perfectly with a factory 2.5FW (europe) .

I think it is wise if you upgrade to 2.00 and then downgrade it back to 1.50

Yes, that's what I thought, thanx.

And I've just done that, but I got a little scared because the downgrader (I mean the version changer) didn't create the index.dat.bak file as it should.. Still, I as able to upgrade to 1.5, but..
What do you think?

In the end it seems that everything went OK..

Yes upgrade from version 2.5 to version 2.6 then use the downgrader. Yep the code is alright. For the 2.60 update go to psp-hacks.com and go to downloads section then firmware and look for it in there. As for the dump go to psp-hacks.com and look for the 2.6 downgrader package as it includes all the files necessary. It doesnt matter if i have already answered these questions. I was once like you...

Thanks alot for all the help mate. Waiting for my 4gig card to fill up with homebrew now

What I wanna say is if I as able to upgrade to 1.50 the version changer worked regardless of the index.dat.bak file creation, right?
This file doesn't have nothing to do with the downgrader itself, right?

All seems fine, I just want to be sure..

TIA for an answer.

This downgrader worked perfect without any problems!
My PSP originally came with v1.0! So i guess that's why it worked so good. Just the problem is some of my new games are 2.6 games and Splinter Cell doesnt work with the UMD emulator so i went back to 2.6 for now until they fully crack 2.6 firmware so it will work. Is there any problems with upgrading and downgrading multiple times that can mess my PSP up?

Thanks.

just confirming to some readers that the downgrader has worked ok for me.
i purchased my psp 2.6 version second user off ebay, i had no idea of it's history, whether it had been upgraded or was original 2.6 version.
there was no printing at all on the psp's board where told to look before attempting downgrade so i took a chance. it worked fine for me.
whole process from start to finish took around 4 minutes.
i used the downgrader 2.50/2.60enfull.exe file with the talk through guide on pc.

Another success here downgrading it to 1.5 with a NON TA-082.

Updated FACTORY 2.5 -> 2.6, then from 2.6 -> 1.5. Checked system firmware and its now 1.5

Good luck!

my letters are in the top right of the mobo but i cannot read them, should i automatically assume that it is a TA-082 and screw it or should i take my PSP apart and look/ try and decipher the numbers?
