2.5 downgrader!!!!!! i found this out at psp 3d 2.5 Downgrade (Need Testers)

--------------------------------------------------------------------------------

If anyone is willing to test out an exploit for a 2.5 downgrade (I've gotten it to work pretty well), PM me for more details. Just need some testers here...

UPDATE TIME (pun intended ):

What we know:
USB can be connected to the PC and the PSP although the PSP says it's not
The 2.6 update starts while the USB is plugged in (still holding a connection to the computer)
USB wires are not to be messed with :P
It's a PSP bug that triggers the USB trick, not the USB cable
Doesn't work with 2.0 or 1.5 (thanks stupid)

What we do not know:
Does the update continue after swapping the eboots out?
Is this possible with 2.01/1.52/1.51?
Does the computer loose connection with the PSP after being 'tricked' after a while?

THE METHOD (for those who don't like to read):

Quote:
Step 1 - Required is 2.5 firmware...anything lower/higher...don't know, haven't tried.

Step 2 - Go into USB mode, wiggle the USB cable loose a bit and wiggle the cable in and out until it says 'Connect a USB Cable', although it's connected and on your computer the PSP Drive is present. Kind of a trick to the firmware, I don't know much about it...

Step 3 - Go into and load the 2.6 Update, however, since the PSP is connected to the PC still, simply load the upgrade into the first EULA screen, then proceed, make sure no AC cable is connected...when it prompts you to connect the AC Cable, first swap out (remember the PSP is connected to the PC via USB mode, you 'tricked it') the 2.6 eboot with the 1.5. Seems dumb and impossible, but it works and continues the update, downgrading to 1.5...however, I upgraded back to 2.5...tried it again, and bricked the PSP.

The key is to swap out the eboot when you're prompted to plug in the AC adapter as opposed to during the EULA, since the PSP will execute the file after the EULA, whereas, if you swap AFTER the EULA, it'll execute without processing...or something. I don't know much information, other than, if you can get the USB part down and pretty much follow step for step, it worked for me (once).

No reason to read anything further than this unless you want to partake in the discussions

psp.3d eh???? there stuff is usually bs anyway, and the theory sounds bull too.

**st.jimmy** · 12-03-2005, 06:59 PM

i dont understand+ i want a video.

**Syphon** · 12-03-2005, 07:02 PM

Doubt it works...

how could you have it out of usb mode and still have it working? and when you update it doesnt stay in usb mode, downgrading is not that easy

**Syphon** · 12-03-2005, 07:04 PM

BTW, you should have copied the ENTIRE post from psp 3d. Before some noobs come and mess something up.

well you wiggle it around until the psp says 'insert usb cable', but the computer is also communicating with the psp device. You start the 2.6 update, accept the aggreement, swap the eboots, and the 1.5 update starts. sounds like a psp bricker.

**MICHAELSD** · 12-03-2005, 07:19 PM

You need anything launched on your PC? *coughs*epsp*coughs*!

EDIT: Seems like it might work since MPH used an unedited 1.5 update. The USB thing, I'm not too sure works. Wouldn't the PSP give some error? Or, your PC say its in use stop all programs that could be using it and try again?

**Matt123** · 12-03-2005, 07:28 PM

If you say 'works' in your topic this must mean you've atleast tested it right? I doubt it, and I also doubt this works, it's a dumb concept.

Ok, go and test it. I mean, you were willing to test out ePSP first...

**TeamOverload** · 12-03-2005, 07:29 PM

if this is true i will wait for a new update so i can try on 2.6

**Mast3r_Shak3** · 12-03-2005, 07:33 PM

well for all u rich boys out there... go buy a new psp and try it. i mean lots of u ppl got like 20 PSP's lol

**whitehawk** · 12-03-2005, 07:34 PM

Listen to someone who knows, it's fake.

**Eclipse9069** · 12-03-2005, 07:43 PM

You can not downgrade a 2.5+ firmware that easily, due to where the new "index.dat" is located. There is still the old "index.dat" which is guaranteed to brick your psp, no doubts about it. First you need to find out where the new index.dat is, and how to create a new index.dat.

so.. !!WARNING!!
Do NOT use this downgrader as there is no way it will work. It will just brick your PSP.

**Syphon** · 12-03-2005, 07:49 PM

This is just another ploy by psp 3d to get more hits. They're already "seeking bandwidth donations"...Think a post like this would attract hits to help pay?

**Train** · 12-03-2005, 07:53 PM

This is not by PSP3-D this is by a member of there forum....I am a hack team member there and I admitt that there is NO possible way that this would ever work!!!lol

**Eclipse9069** · 12-03-2005, 07:55 PM

Mods, so this doesn't get out of hand and so the noobs don't cream their pants; Please lock this thread.

KarakuraKing · 12-03-2005, 08:01 PM

Its fake. Tested it. Basically it will not work. You can wiggle the whole night and will not work. The usb works in a way where all four cables are connected meaning any one of them were to disconnect, there will be no connection. And the files are encrypted. Dumb loser post some stupid idea...Please close this thread already...sick.

WishboneAsh · 12-03-2005, 08:02 PM

Indeed, PSP-3D is typically the home of overhyped bull'crap'....it most definetly looks like they are just seeking more popularity.

**muki** · 12-03-2005, 08:06 PM

I didn't think it would work, though I found the theory itneresting enough to try a little experiment. I just wanted to see if it was possible to "wiggle" the USB cable enough to still have access to the memory card through the computer, but making the PSP believe it's not connected.

Experiment failed. No amount of "wiggling" could get it into a state mentioned above.

like i said earlier, this was not done by psp-3d this was done by a member of our forum and since anyone can post stuff on the homepage they posted it, but i just locked all the threads about this there until they have proof of this working....

Ok fair 'nough, you (i.e. PSP-3D mods) would be better off moderating the forums more tightly over there IMO....there's no end of pointless posts over there and kids re-asking stupid questions (2.5 downgrader working yet? blah), as you've all probably noticed now: that + its past notority for jumping the gun on exploits has f*cked the sites reputation.

Clutch13 · 12-03-2005, 08:16 PM

ok i tried it and it bricked my psp ok so no 1 try this : wink : :wink:

**Jake** · 12-03-2005, 08:16 PM

The people from PSP 3D are proven liars (4 out of 4 "discoveries" busted) who are only interested in making a profit off of your time, web hits, and desperate generosity.
