Downdater UPDATE July 2: DOWNDATER_FINAL_AUTO released!!

[Arlik]

I downgraded, but now my background has some 3D symbol and it says aphex twin in the top right corner. why is this?

I asume you got the same 1.5 dump as I got. So what I was told was that the person who gave me the dump had used flashmod or some othe program to change his background. So I downloaded flashmod and used it to put the settings back to default.

[birdman]

plug your psp in to the ac outlet, one guy downgraded his psp with 4% battery left LOL

[torrobinson]

I had a 1.5 upgraded to 2.0, then 2.6, then back to 1.5...

[The_Lead_Factor]

There have been two confirmed Bricks with this so far. One wouldnt stop blinking and the other refuses to turn on.

Ok, I have found a way to make the 1.5 more stable after you have successfully downgraded from 2.6/2.5. After the PSP reboots its ok if you get the corrupted settings screen, just press circle, and then when it says UMD not readable thats ok too, just restart your PSP(may need to multiple times). But since you used the GTA UMD to downgrade you also have the 2.0 upgrade right there on the CD, so upgrade and then downgrade again with MPH so u'll have a clean copy of firmware 1.5 instead of a dump from someone elses dirty PSP :P.

I have tested this myself and it leaves 1.5 far less buggy and glitchy

[Brickhouse]

Hey, birdman do I dump these files into the PSP folder. I have two folders at the top level

PSP and UTILS and then a couple of other bin files and IND files.

Awesome. I'm going to try that too. WOW, that MPH one was quite a riot for me. I was scared to death a couple months ago when I was attempting to go from 2.0 back to 1.5

[The_Lead_Factor]

Those are not the correct files Brickhouse.

[D4RK-V1P3R]

There have been two confirmed Bricks with this so far. One wouldnt stop blinking and the other refuses to turn on.

Not bricks, these are explainable:

if it keeps blinking you have used a 32MB memory card that has overfilled and cant hold any more data as the downgrading process writes ALOT of logs that take up at least 16MB from what we've found so far

the one that refuses to turn on has a dead battery, or a bricked battery, which is fixable, by a new battery or a charger

[Arlik]

just so you know this isnt my dump, mines clean

I recieved my dump link from, which I don't quite remember his name exactly, 'freeplay' or 'fourplay' I'm not sure. He was the one giving the link in IRC.

But its easy to fix. Just download Flashmod, boot it up, and reset the settings.

BTW: Could anyone link me to a devhook install guide. I know there is one on this forum but it didnt quite correspond with the version number I had so i'm wondering if it would be okay to still use that one or if theres on for 41d?

lol i know why its glitchy and so does everyone on plantepspirc

the downgrader simply over writes the 2.6 firmware files but what dark_alex and everyone forgot was that 2.6 has extra firmware files,

so when you downgrade you still have fragements of 2.6 firmware on your psp.

[The_Lead_Factor]

Isnt this downgrader suposed to re-format the NAND?

yep. thats exactly why you upgrade and downgrade again, clean FW

HEY, SHHHH, u cant give that out, thats classified stuff

[Brickhouse]

Those are not the correct files Brickhouse.

On my mem stick I have PSP and UTILS. I opened up the PSP folder to dump my PSP and DOWNDATER folders that Birdhouse sent me.

I think that is the correct place. It has the eLoader folder...Game folder...etc.

[The_Lead_Factor]

Cant be. This does re-format the NAND so you would start off with without any 2.60 files anyway.

[birdman]

Isnt this downgrader suposed to re-format the NAND?

the old versions that bricked were doing that, this one doesnt, because when you reformat for some reason you cant use the system calls from a emtpy NAND

its like burning a peice of paper into ashes then trying to read what was on it

You put the DOWNDATER folder in the root of your memory stick.

simply drag the PSP folder and the DOWNDATER folder from the rar file i send you over to your psp root then go into elader and launch downgrader test

[Arlik]

Errr... yah. Sure thing sergeant.

[frozenfire]

yep. thats exactly why you upgrade and downgrade again, clean FW

Do you mean to 2.00 and then back to 1.50.

[Brickhouse]

okay, here I go. (taking a deep breath) I'm scared to even look.

[djt123]

Do you mean to 2.00 and then back to 1.50.

yes, thats wut he means

[FireMonkey]

Does anyone know that if using a corrupted 1.5 dump that it will lead to my psp being bricked? If it's ok I would like to post the link to where I dowloaded it.

[D4RK-V1P3R]

ok, it seems that everyone has been confused about the folder names it should be like this

ms0:PSP/GAME/DOWNDATERTEST/EBOOT.PBP

ms0OWNDATER

[JoshuaC]

okay, here I go. (taking a deep breath) I'm scared to even look.

Hope your PSP doesn't share the same name as you :ROFL:

[birdman]

Do you mean to 2.00 and then back to 1.50.

yes


Btw no one knows how to do kxploit or how to install irshell? this makes me cry inside.

im gona write a faq on how to install 1.5 homebrew, and im gona cry while i do it

[sosa2004]

I had a japanese white factory 2.5 psp, later upgraded to 2.6

and the downgrader went smoothly no problems

thanks to everyone involved in the development of this downgrader, and thanks to birdman for helping me through with the method.
