THIS STILL NEEDS THE GTA - ELOADER, WTF! GET OFF THE GTA AND DO SOMETHING WITH OUT THEN MAYBE THOUSENDS OF PPL WILL BE THRILLED. 8-| JUST ANOTHER 3′RD PARTY APP’ NEEDING A FORTH PARTY APP TO USE A 5′TH PARTY APP SO YOU CAN USE A 6′TH PARTY APP.

TO THE NOOBS, WTF! YOU CAN’T UNDERSTAND THE USE OF COPY AND PASTE TO YOUR PSP? PPL REALLY NEED TO COME UP WITH CRAP LIKE THIS? :)) NOOBS ARE TO FUNNY.

I had a PSP with FW 2.01 then i update to 2.50
in the UMD slot is IC9001

can i downgrade ?

I will be happy only if you make the ta-082 PSP’s work.

Lol it seriously doesnt get any more easier then this…u noobs are sooo lucky to be spoonfed all this stuff…

nice job xtrusion

I Already Have a 1.50, (Downgrade a 2.00 PSP) So I Don’t Need This Downgrader or Modchip, Im happy With 2.50 On Emulated Though DEVHOOK

Awesome work…although i still think doing the whole thing manually will benefit me better(dunno about you guys)…this is very nice for the newcomers that are looking to downgrade…nice work dude!

Oh well, I have 2.7 so this wont work for me anyways.

I had 2.50 and heard downgrader (the one previous to this post). I upgraded to 2.60, and then decided to risk it. With the files I downloaded from this site, I had no problem at all. I now have a 1.50 PSP.

Thanks to everyone that has contributed, and to the complainers? If you don’t have something nice or useful to say, how about just keeping quiet?

Worked like a charm!

yeah get the fuck off with gta i dont feel like spending 40 bucks to get a shit game. just make a downgrader with out gta and BAM thats it

The instructions tell you to go in and delete all the files off your mem stick….

It’s much quicker to format from the system settings menu FYI

To x, who cares, and the like…I’d like to see you come up with and exploit to run homebrew code without GTA…otherwise shut the fuck up and quit complaining.

Two things that make this downgrader whilst good, not much use to many.

1. No good those who bought a PSP with 2.5/2.6 preloaded.

2. Most people who upgraded from a usable F/W version most probably have been dumb enough to continue to upgrade to 2.7+ by now.

For all those bitching about having to use GTA to use this downgrader, someone you know most probably has it, or a video/game rental store may have it to rent.

To Adam. Take your opinion and STFU. Gta aint worth spending $40 bucks on and never was. To whom that think i need it. lol what a laugh. I have a 1.0 but do you see me bregging about it like the rest of the IDIOTS on here? Just stating GET THE FUCK OFF GTA. As to cracking the 2.5+ firmwares. I aint updating my PSP to get you fucks happy id and when it was done.

ya know what i say get the heck off of downgraders!!! stop wasteing all of your time on downgraders and make apps on 1.5 for use smart enough NOT to upgrade! If you have 2.6 or 2.5 you deserve to spend $40 to downgrade so you stfu!

i had a 2.01 upgraded to 2.60 a few months ago to play socom umd and downgraded yesterday night my mother board reads ic6001. i also downgraded my mates factory 2.60 psp with no problems at all and his mother board also reads ic6001 so i dont know what the warning means on the downgrader when it says it wont downgrade a factory 2.50-2.60 psp,anyway just sayin thanks to the developers who worked a long time on this exploit.

guys at psp-hacks, i have downgraded from factory 2.6, so it should work!!!

gj tho for all that made the downgrader possible….

Thank you, coders and the like for making my PSP one of the best sources of entertainment I have.

I have a psp with FW 2.5 should I upgrade it to 2.6 first before using the downgrader? Also, can you still repair a bricked psp?

quick question if you delete all the files that were put in the psp through this file would you go back to 2.5/2.6 i cant tell you because i have a 2.71 i got all excited about new ps1 emu and upgradedand another thing does the mod chip tell you that you have both versions at the same time or do you switch back and forth

ACTUALLY, ITS BEEN PROVEN THAT IT DOESNT MATTER WHAT THE FACTORY FIRMWARE WAS! PEOPLE HAVE SUCCEEDED IN DOWNGRADING FACTORY 2.5s

Hey I installed this downgrade and a bunch of stuff is working great…BUT

I can’t get NesterJ or RIN to boot. Any suggestions?

na man sry

My friend uploaded the 2.71 version and now i hate him
i wonder if i can downgrade it with this one??
if i do what will it happend????

i still dont get it tho?! if its 1.5, why we need to use the shitty gta loader? why cant we just use the kxploit that was found ages ago?

OMG!!!
JUST CAME BACK FROM THE SNOW!!! TYIED IT AND IT WORKS!!!

it is soo easy yo do, no way you can fail!!!! thank you sooooo much

I HAVE a factory 2.50 PSP used the downgrader..followed the insttructions and it worked like a charm ………..

fuck yeah

So does this program have the 1.5 dump files?

how would i know if its ta-082? does dis still need a gta umd? please let me know. tnx!

mistake the letters say ic6001

so if the letters say ic6001 does that mean that is it a ta82 or not for is it a ta 81 beause my psp was one from japan and it was one of the first

My psp brick after using the program…

I have factory 2.6 and in the umd place isnt a number can i downgrade my psp?? Please help!!!!
Thanks:D

If there is no writing you have not got a ta-082 thus you should be fine, don’t take my word for it tho i jus downgraded my factory 2,60 with the code ic6001 which you shouldn’t be able to downgrade but it worked and now im running homebrew app’s with ease. Thanks to all who worked hard on this downgrader. keep up the good work

Thank you! i will try it but at first i need GTA i have to steal that!:D

when i originally bought my psp it had 2.5v firmware (and still has) how do I know if its a factory made 2.5 or just upgraded version ?

wow…diddnt think this would ever happen a real downgrader…oh well i have no intention of using it

O.m.G thx so much now my psp is 1.50 thx XD

and f0me its not for noobs its for people that didnt know 1.50 was good and thought 2.60 was the best

do i have to find a dump of version 1.50? or i just need easy auto downgrader? ( i already have gta.)

U Just need auto downgrader, i didn’t have a dump ver 1.50, i was really worried when i did it tho, it’s an expensive gamble but im glad i did it now.

to edfuk:

thank u man. i’m gonna downgrade now :)

What about upgrading again once it’s been downgraded can that be done? … and then downgrade again?

Or should one just used DevHook once downgraded??

IS IT ALSO POSSIBLE TO DOWNGRADE WITH A FACTORY 2.5 VERSION??
OR DO U NEED TO UPGRADE TO 2.6 FIRST??

THANK YOU,

Excuse me, but shoold I have a game GTA LCS (old version) to daungrage my PSP?

I have a factory 2.5. Should I upgrade to 2.6 and then downgrade, or does it make a difference?

how does the GTA LCS exploid work?
anyone got a link for me?

yo this thing makes it so easy and it worked i am sooo happy…sony got pwned

I succesfully downgraded from a brand new european factory 2.50 PSP, so it DOES WORK on factory 2.50 and you DON’T have to upgrade to 2.60 first… And yes, 1.50 is awesome!!!

This program worked like a charm.

All you need is updated your PSP to 2.5 or 2.6 and a copy of GTA.

The program automatically installs everything that’s needed with excellent instructions!

Good Work!

i have a a jap white psp upgraded it to 2.60 from the factory 2.01 will this work with no problem has anyone tried it thank you…
