[Updated] 0xFFFFFFFFailSploit 6.39/6.38 Downgrader v3.5

Post by some1 » Mon May 23, 2011 3:08 am

I present to you my port of Davee's 6.35/6.31 downgrader to 6.39/6.38.

This a very simple app, just put the official 6.20 updater in (ms0/ef0 accordingly)PSP/GAME/UPDATE, and run the downgrader, this will reboot into the 6.20 "update", and allow you to downgrader to 6.20. Has been tested on 1k, 2k, 3k, and Go (added support for 07g/09g).

I will be releasing the source on May 29th.

Thanks:
[spoiler]To Davee for making the original 6.35/6.31 downgrader
To ultimakillz and skyend for being my mentors when I first entered the scene.
To n00b81 for teaching me a lot of things.
To Davee, Freddy, TheLemonMan, Hellcat, and Draan for answering any question's I've had.
To TiPi and Nymphaea for allowing me to work on their VSH sploit, which gained me alot of knowledge and experience.
To Npt for hosting such an awesome competition!
To Arnold, for fixing things here and there.
To All the people who beta tested!
To TiPi for the awsome icon0.
And to many others that I'm probably forgetting.[/spoiler]

v3.5 Download: http://www.mediafire.com/?i8ae1j3xdxpshwj
v3.1 Download: http://www.mediafire.com/?jfavewhvu85jrz2
v3 Download: http://www.mediafire.com/?hhvqimvthbtrvis
v2 Download: http://www.megaupload.com/?d=0VBRZ8ZN
v1 Download: http://www.megaupload.com/?d=ZYEU7KFI

v2: 09g/07g support added.
v3: added support for 6.39, added model printer
v3.1: Fixed idiot bug for 6.38 I created when adding 6.39
v3.5: If the 6.20 updater MD5 check fails, it will check if the update file is 6.35, allowing non 07g/09g to downgrade to 6.35, added source, removed a few debug printf's

Instructions:

If you have anything lower than an 07g place the 6.20 update in PSP/GAME/UPDATE.
If you have an 07g or an 09g, place the 6.35 update in PSP/GAME/UPDATE.

No screenshots added because it's only text (splash screen as pic1).

Important note: You run the application at your OWN risk. I am not held accountable if you **** up your PSP.
Another important note: After you downgrade to 6.20, you will get a BSOD (saying that your system information is corrupted), this is OK, just click circle to reset your system information and you will be back to normal.

Final important note: It does indeed still support 6.35/6.31

Hmm, a demo user mode exploit doesn't seem as important anymore, I wonder why... xP

I smell bullsh*t/fake.

So your telling me you have found a new kernel exploit for 6.38?

6.35\6 kernel exploit was patched in firmware 6.37.

This seems oddly suspicious, someone should test this on a 1k.
* PSP 3001(03G) w/ an 8GB Memory Stick & 6.20 PRO-C2 Permanent
* Laptop - Acer Aspire 5742z w/ Windows7/8 & Ubuntu
* PS4 (Think I got enough to buy one when it comes out X_X)

I smell/spot an ungrateful user, Test before you attack/claim or wait till someone does. :roll: Just tested on my PSP 3000 03g, updated it to 6.38 from 5.03 then ran the downgrader with 6.20 UPDATE in PSP/GAME/UPDATE directory. Works perfectly, now at 6.20 without a brick happening.

I'll give it a test on my 1000, too when I get the chance. Some1 wouldn't fake something like this just to ruin his reputation.

@Some1, Nice job! This is going to give a lot of people @ 6.38 a second chance; plus you're going to give everyone a run for the money in the Genesis Competition I seriously didn't expect this.

@Steven,
http://www.mediafire.com/?4try7sfcgmb6tme - Mirror Link (Old Download 6.20 ONLY)
http://www.mediafire.com/?u6xx3g794r99xcd - Mirror Link (New Download 6.20/6.35)

EDIT:
Make sure you have a PSP Model below 07-09g first.
1. Grab the 6.20 UPDATE EBOOT.PBP and place it at PSP/GAME/UPDATE
2. Place the downgrader in PSP/GAME/638 Downgrader/
3. Run the downgrader, follow the instructions and then wait for it to boot the 6.20 OFW Update
4. When PSP Reboots press O to reset settings, Enjoy.

Same as davee's downgrader if you ever ran it.

confermed the downgrader works from 6.35 ( I was too chicken to update to 6.38... :) ) so it functions as a downgrader.
my stuff
  • PSP 3000 White (03g) - Dual Boot (6.60 Pro-C2 and LME 1.8)
  • PSP 2000 Simpsons Ed. - 6.60 ME 1.8
  • PS Vita Cosmic Red - FW3.01
  • Sony Vaio E-Series Laptop White
  • Samsung Galaxy S4 International (Rooted)

confirmed it works from 6.38 OFW Mode (6.38 ME-3), seems real!


But crappy for PSP 3000 07g and 09g User, they cant downgrade to 6.20, so please make the downgrader compatible with 6.38 --> 6.35 !!!


But dang nice work man!
