How big is the risk to 'brick' your PSP ???

people, i can confirm that this is indeed a 100% working downgrader for 2.0 to 1.5

i tested it myself (got it from a torrent site, but same file)
and enjoying homebrew on what used to be my 2.0 psp

this is safe, follow instructions, and don't piss your pants when you see the black screen with the white numbers, just unplug and reset (or take out battery) then install the "upgrade" and follow instructions.

it stops at 99%, then shut power of (pressing power for about 10 secs until it shuts off)

restart, at the blue screen press O and it restarts again, congrats, you've now got 1.5!!!!

finally dudes (and dudettes ) it's here!!

(DONT RUN ON 1.52!!!!!)

love it!!!thanks

IT REALLY WORKS FINE
DON'T WORRY TO BRICK YOUR PSP
WAB SUCKS
MPH OWNZ

I've opened the photgraph, got the extra file on my psp, ready for PSP 1.5 Update (the downloadable one), but can't do because of lack of battery Life??? (try again later, wich I can later on (I hope)

The thing is, I'm on 1.0 firmware version now??? Is this correct ??

And do you HAVE to take the Japanese 1.5 firmware version? Or does that not matter? (Can't I use my Metal Gear Acid 1.5 update???)


Greetingzz

im a little unclear on the instructions, do you put the index file and the .bin file in the mp_root folder outside the movie folders, or is the root you speak of somewhere completely different? i tried the way i just said and had the overflow pic in the photo folder and the update folder in place but when i disconnected usb mode and went to photos on my psp screen it would freeze for a second then shut itself off. im pretty sure i have the .bin file and the index files in the wrong spot, please specify where i should put them. thanx man, i boght mine with 1.5, but before i knew about all the homebrew i updated to 1.52, and then 2.0, so im really looking forward to some good ol' mariokart.

Has anyone tried FastLoader yet or UMD Emulator on the firmware downgrader, if so does it work

I'm using UMD Emulator V0.8C

and i'm playing Need for speed Underground Rivals and Ridge racer now

1 thousand times thanks for all the guys who have worked hard to accomplish this downgrade!!

I wass worried when i bought my psp and upgraded to 2.0 without thinking about the downside of it.

Now i can finally play my downloaded games!

Worked absolutly fine for me!

Although, i cant seem to change my theme now (Not that im bothered)

Works great! Great job of hacking and thanks to everyone involved! KUDOS!!!

how can you contact the author of this program?
is there any news on an update?
is there gonna be a umd emulator.9?
if so when?
i can't get coded arms to work in .8 but it works in .7

HI GUY'S JUST WANTED TO LET YOU KNOW THAT I HAVE SUCCESSFULLY UPGRADED MY PSP-1004K V1.52 TO US V2.0 THEN DOWNGRADED TO JAP V1.50 THE SYSTEM WORKS GREAT AND I CAN NOW PLAY HOMEBREWS.

KUDOS TO MPH AND PROGRAMMERS WHO MADE THIS POSSIBLE.

THANKS

O......k..

This is the 3rd topic you've said that in, we know it works!!

were can u download the UMD Emulator V0.8C from Redbullc

How do I upgrade from 1.52 to 2.00? The Network uprage would put me on 2.01. Can anybody help? Thank you.

there is a trojan in the overflow.tif file
++ I can't see .tif pictures on my euro v2.0 psp can I?

It is very easy!! I was done!! So cool~~

the root folder is:
goto my computer, then when you connect your USB cable to PSP<>PC, the removable drive that comes up(in my case H:) is your root folder!

Hi All,
1st off
Great info and guides here, I have read through most and undertstand exactly what I need to do.
so thankyou

But!
Before I take the plunge and downgrade I hope you may be able to clear something up for me.

I read somewhere that you should'nt run MPH downgrader if you upgraded from 1.52 to 2.00 from the UMD that ships with the PSP?

Is this true? or is it exactly the same as the DL'd version?

Thanks In advance

Hi Deadalus,

When I received my UK PSP I updated to 2.0 using the demo UMD and then later on I downgraded with the MPH downgrader with no problems.

Cheers,
Z.

Thanks Zoidy

Thanks in advance...

Just downgraded! A bit of fooling around but I am now playing Mario SNES Games! awesome!

No problems with downgrading as of yet.

Hopefully it will continue to be fine!

i just was wondering why this wouldnt work with 2.6. it tricks ur psp into thinking it 1.0 right then u just update


p.s. im a noob

Hi
i am new to the forum and i am not sure i am posting this msg in the right place. I just wanted to know can a PSP with firmware 2.01 be downgraded?

Thanks for any help

Link isnt working.

i can't seem to download this... i click I AGREE button, and it goes to "PAGE NOT FOUND"... HELP

c'mon guys, can some re-upload this????!!?

It's been awhile since I downgraded mine,, but I'm fairly certain it doesnt work with firmware higher than 2.0, and (I believe), that the 2.01 firmware was released to stop this particular method..

If you've got 2.6, I think you'll need to find another way..

There is no way to downgrade a psp with firmware 2.01 or higher.

I have an Australian psp-1002 psp that had 2.00 firm wire on so u used this downgrader and the 1.5 (well at least that what it told me) and now my psp says its vir. 1.00 and it still has a web browser and network update. Is this normal.

p.s. ive only used eboots on my 2.60 before so I don’t know how to work them and my 1.00 any help? Should I upgrade to 1.50?

wtf...

i don't know what to tell you, it sounds like bullshit to me. you say you had 2.6, and then downgraded so i have to assume you're making shit up, please don't clutter our boards with stuff like this.

if it is some kind of fluke and you somehow have an internet browser on 1.0, you should dump your firmware with one of the tools on this site and upload it to a few places for testing.

i wouldn't reccomend upgrading until you've done this.

Sorry man put the 1.50 on later to day and the downgrade was on my 2.00 psp not 2.60 I still have all 1.50 eboot that I used it that could help at all, jst pm me if you want it.

i've downgraded before... and its alright everyone... its absolutely safe.... well.. not absolutely.. but... i've done it at least 13 times... and nothing wrong has happened
