Ok here's what I did, I have a 1.51 PSP from Europe and it comes with a UMD that has the 2.0 firmware on it. So I put in the disc and started the upgrade, and at the point where it said "make sure the PSP is pluged into an AC adaptor" or something like that I can't remember it word for word. It is the last point at which you can cancel the upgrade. Anyway before I continued I removed the disc and inserted the Midnight Club 3 disc and then continued. Being that it had already bypassed the version check it continued to load the firmware thinking that it was the 2.0. Now I know that this works because I tried it on three of my friends PSPs all 1.51 I tried it on mine first so I wouldn't brick theirs. And all of us can run homebrew cool! I am guessing that this will only work on 1.5x versions seeing as how you can't use the 2.0 disc to upgrade one with 2.0 already on it. I hope someone will find this helpfull.

And yes I know I only just joined this forum but that it because I only just got a psp and became interested in the hacking and homebrew stuff.

Is it possible for you to make a video of this concept in action? But alot of people have been saying this concept works, i havent actually got a UMD with 1.50 on it though. But in theory is sounds believeable.

Anyone else tried it? Or willing to give it a go!!

I would like to get a vid up to this or another site, But I need to get with one of my other friends who has not upgraded theirs yet. I am unable to do it again on mine as i don't have the 1.5x firmware and this will not work with 2.0 I am also a little worried about posting a vidio because there will be a torrent of nay sayers that will find some reason to call the video fake. Like the light was a little off in frame # whatever or many other reasons. Anyway I will ask around today and see if I can try it on another guys PSP to make the vid. If not I can always buy one do the trick and take it back to the store if need be.

Well if you just create the video with a good quality camera so we can see everything i dont think we can call it a fake. Some of the videos being posted have been awful quality so of course people are going to assume they are fake. Be good to see this concept in action though, nice find by the way!

Midninght club 3 has firmware 1.52 on the umd disc though in EU?

I didn't know that I imported mine through lik-sang.com but could not get the psp imported, couldn't afford it so I thought all versions were the same I'm sure there are other games that have 1.50 on them over here as I don't have but two games I can't say which ones have what firmware on them. The other one I have is Tony hawk and it has no firmware on it.

And also all EU PSPs come preloaded with firmware 1.52, not 1.51. I smell bollocks.

Sooooo sorry, I made a small mistake in the firmware number .I didn't pay that much attention to it as I already knew that it would not play the homebrew stuff like I wanted. Anyway it was 1.5x whatever I will make sure I get the version number right when I make the vid later today. Althought someone will undoughtly find flaws in that. All I know is it worked and I got my homebrew and iso loader working. reguardless of if it was 1.51 or 1.52 it is now 1.50 and I am happy and so are about 3 of my friends.



And why would you want to smell "testicles"? I guess that's your buisness

Yup sounds like a load of old "CODSWALLOP"

I have edited my post.

SONY said that you must follow All directions while updating and if you fail to do so
it may result in damage to your unit, therefore, if this guy swaps out disc's during
the install and the psp goes into flash mode/ and the flash is incorrect = DAMAGE !

I'll wait for the so-called' Video proof (hopefully its nice and clear)

Accually the UMD does have 1.5 on it if you look at a dumped iso image there is a folder in it called "update" and that contains an eboot file witch is the 1.5 firmware. Death jr has the same folder only a diffrent eboot file.

really?

is this the FULL update or just the text that shows up on your screen, stating you need
to update?

I was under the impression that the disc wouldn't play until you updated your psp via
sony's website?

i never knew the update was inside the game?

thanks for the info !

wow . . . ?

No prob, glad I could help my guess is that they put it on the umd for people who want to play the game and don't have access to the website at the time or the internet at all. Oh and it is the full version of the update.

It's a British saying. If you smell bollocks, it means you suspect someone of talking bollocks as it makes the air smell of bollocks as they talk.

At the moment I still think it's bollocks as things like this have been tried many times before. The firmware updater has been decompiled and there is no way of tricking it like this. It will bomb out with an error.

Patty,

get it on video and then ppl will stop doubting u. I cant beleive u are claiming you have downgraded 4 1.5x PSPs and not once did you or your friends think to get it on film... even a camera phone has good quality these days....

...anyway im sure everyone awaits yr proof!

Del

i will retract my previous statement

Yes, Midnight Club EU is a 1.52 game, Death Jr is a 1.50 game.

it sounds so simple ?

just a simple swap ?

this is why it is hard to believe.

Do your best to get good quality/ maybe sound?/ the whole psp/

AND FOR GODS SAKE: PLEASE DO IT IN THE DAY TIME/ or OUTSIDE !!!!!!!!!

thanks!

I know it's just the literal meaning of bollocks is testicals. just my vain attenpt at being funny

well, i just checked your info on the fw in MC3...and unless the full 1.50 firmware is 3651kb. I would say your wrong

The 1.50 version of the firmware does not have to be very big like the 2.0 all it did was add some security features unlike 2.0 that added a web browser and the background changer. Also it may be compressed in someway that expands as you install it after all 3.5mb if kinda big for a psp eboot file.

Also when i make the vid how will i get it to you guys to see. Can I upload it to this site since i don't have a website in which to host it.

i upgraded my 1.00 psp to 1.50 using the update, and it was 15mb not 3mb

www.yousendit.com

upload to there

Well all I can say is that is how I did it and there are others who have updated their psp's with just a game. Also there are updates on UMD movies for instance "land of the dead" and "saw" also have firmware upates on them too.

just email the vid to one of the sites MODS or the ADMIN.

When do you think you'll have another victim , i mean test subject to
record the process?

Or you can update your psp to a 2.0 (while recording) and then use your
swap method to downgrade it to a 1.5 (while recording)

Don't worry about the lenght of the video.

download the 1.52 firmware off the sony site if its still available, reflash to 1.52 and downgrade again on cam

I can't upgrade mine to 2.0 because if I did when I tried to do the trick and I put in the disc with the 2.0 firmware the psp would tell me I already had the latest version and there was no need to update. As for my next victim I have asked my buds to ask around and show theirs to see if there are any takers if not I will just go buy one do the vid and take it back HAHA!

"download the 1.52 firmware off the sony site if its still available, reflash to 1.52 and downgrade again on cam"

I'll look there now I thought it was replaced with the 2.0 version.

v good idea...

Sorry it only allows me to download version 2.0 It also states that you can update via a UMD disc but only to 1.52

Yeh most UMD games and films come with the firmware on them, usually 1.52 or 2.0 in Europe, i still wonder what version of Midnight Club 3 you were using to get 1.50??

But yeh, ill just wait patiently for you to show us a clear film

http://forum.lik-sang.com/showthread.php?t=4766

1.51 FW there for d/l

It was the North American version of Midnight club 3 and it will most likely be later today when i get to make the vid and encode it so as not to be too big (but still clear)

Or it will be later today where you vanish from the site and register as a different user. The mods should just close this useless thread.

Ok I got the file I will update mine and then make the vid of me downgrading or do you want me to capture the upgrade then downgrade on the vid.

well obviously we will need to see the b4 and after firmware version from system info

I know that I was asking if you wanted to see me upgrading to 1.51 from 1.50 then back to 1.50 or just the part where I go from 1.51 back to 1.50

well the vid upgrading would be long as hell, so how about just showing us on the vid that its a 1.51, then continue to the downgrade

Ok I just wanted to make sure I got all the right info in the vid that you all wanted so as not to cause confusion as I will probally only do this the one more time so I don't go screwing up my psp be accident.

Cool, well good luck with it, we wont gun you down just yet! Although some people in this thread are being a bit negative, but we will gun you down if we find out that its all bollocks! LOL, just kidding, cant wait to see it.

I actually think this is a good idea and it reminds me of the swaping trick for games.

One of the reasons the firmware EBOOT.PBP inside the Update folder is 3Mb is because there is also the DATA.BIN in that folder as well. EBOOT.PBP is the program that runs to check your PSP, then when it all checks through it loads the data contained in DATA.BIN to update your PSP. If this works I'm going to look for a 1.5 Firmware game.

i got Lumines here that has 1.50 Firmware on the umd

Th only thing That I forgot about is I used the 2.0 upgrade disc that comes with the euro psp. As far as I know there is not a 2.0 umd out in the states is there? I guess you could start with a 1.52 disc as long as it contained a higher firmware than the one you have on the psp. Also I might try this with a memory card too. Like start with the 2.0 firmware on one chip then replace it with a chip containing 1.50 and let you know what happens.

The chip method has been tested and most cases it's either a brick, or the program doesn't want to run it.

I believe this method you're using works better only because the UMD's update folder contains:
EBOOT.BIN [Program to run]
PARAM.SFO [Details to tell program what version of firmware]
DATA.BIN [The firmware itself]

With EBOOT.PBP versions, you have one whole file that contains all the files inside. Before it updates it even tries to check the file you are running with checksums.

Unless if changing the DATA.PSAR files works using the same EBOOT to start it, but I'm sure there are people who have tried that.

All that stuff isn't in the offical download from sony? If not thanks for the info I won't try the chip way since I don't want to brick my psp.

good luck and hope to here from you soon!

remember:

good clear view of the whole psp and make sure the setting
is not too dark, go outside or near a window...
if possible use 2 cams incase one is crap, also do a test
record with you just going though the menus to see if the
cam captures the menu text.

thanks again!

I am trying the test shots now I am having a little trouble getting the text on the psp screen to show up. I went outside to get better light that seems to help a little. It may take a few tries to get it right before I do the real vid since I haven't done this before and this isn't the best cam in the world. But I will make sure all is right before I post it so there won't be any problems. And I promiss no techno music in the background.

Here is a screen cap from my cam showing the sys info can you guys read the info or does it need to be more clear. THX

ok.. so lets say it takes 4 minutes to do this video.. where is it

1.5 firmware is 13Mb and is either a single Eboot.PBP file if by itself, or 3 files as Shihiko posted if it's on a UMD in an UPDATE folder. 2.0 is 15.9Mb and also comes as Eboot as on UMD.

As long as the whole thing is filmed in 1 shot and it's clear enough that the 1.0/1.50/1.51/1.52/2.0 (whatever) can be "kind of" made out on the Sysinfo screen, that'll do the job fine.

Could be interesting...

Pity any new UMD you buy will have a firmware newer than 1.50. Makes this trick quite hard to use, but good on ya if you can find something.
I suspect a sudden surge in sales of MC3, Coded Arms etc.

wtf, why would you want to try the chip way since apparently you downgraded 3 of your friends's PSPs with that UMD trick of yours?
Doesn't make much sense.. :/
Later,
