PS Vita: 3.50 modules + prxtool mod released by TheFloW
People digging for Native vita exploits on the PS Vita will feel happy today. Developer TheFloW (who won our Revitalize competition with his tool VitaShell) released a bunch of Vita modules, which you can basically think of as the full Vita firmware. Update: it’s been clarified to us that only the modules accessible through PSM have been dumped.
The dumped firmware comes from 3.50, and TheFloW emphasizes that this could be used by people looking to Reverse Engineer the modules to, for example, look for vulnerabilities (Native exploits). He’s providing an updated version of prxtool to convert the binaries into assembly code, which should get the right people started on reverse engineering.
Given the sensitive nature of these files, which may contain some copyrighted content from Sony, we’re not directly linking to them here.
TheFloW’s full announce:
I decided to share the 3.50 vita modules (which is actually illegal, but I don’t care) and prxtool mod with you guys, so everybody can take a look at it!This dump contains more modules than you could have dumped with vitasploit (it even contains the webkit module or an other interesting module SceCompatDialogPlugin) The important thing is that all these modules are NID UNPOISENED which means that prxtool will be able to resolve all the known NIDS.I have also included my extended db.json file in this package. This file has been manually adjusted, so don’t mind the order of the NIDS. This database has got some SceAppMgrUser API’s resolved which are very cool for you guys: sceAppMgrPspSaveDataRootMount, sceAppMgrConvertVs0UserDrivePath or sceAppMgrLaunchAppByUri.This is how to translate the modules into ARM assembly files:prxtool -r 0x81EFC470 -i -b -w -n db.json SceVideoExport_0x81EFC470_0.bin > videoexport.SThe -i indicates whether the module is thumb mode or ARM mode. Most of the prxtool’s feature won’t work so don’t bother trying other arguments than these here.Have fun reversing guys!TheFloW

Where do I download the necessary files??
If you checked the source (TheFloW’s twitter post), there’s a pastebin link that has the download link to it.
Very nice work. Im loooking forward to what will come of this. Thank you all for your hard work on the vita.
Well now we can expect articles for Linux on the Vita, but not exploit release! Haha j/k let’s hope someone can actually re-rejuvenate the scene!
Why would anyone want to run Linux on the Vita?
Why not? Lol.
im looking forward to it already 😀 wish i knew some programming 😀
Awesome. Not happy with just winning the ReVITAlize competition with his super-useful VitaShell app (AFAIK the only such one which can copy files between the PSP and native Vita mount points of the memory card which I use a lot recently) he’s only gone and given the scene something that might finally be the key to unlocking kernel mode native exploits. In my eyes he’s continuing the fine work started by Yifan Lu which gave us Rejuvenate in the first place.
Who knows, with any luck maybe a way will be found to downgrade firmwares… could be a long way off but whatever this yields I can’t wait to see.
Thanks TheFloW! 😀
Nice job TheFloW, keep going with your great achievements:)
This is not even about piracy, its about a dead console. I even understand all those who want to import some games from Japan and want to patch it in english.
This is not linux or piracy for me. Its for giving the console some useful content. Some will talk about all the PSP emulation & Homebrew content but I was sick the first day i tried when i saw the Vita re-scalated the original PSP resolution and all the hombrew and games were ugly as heck.
^this.
The Vita is a *** PSP. I’ve owned mine for about 6 months now and all I’ve been playing is NFS:MW. PSP games look horrible on it (OG 3g/Wifi model) but PSOne Classics look okay.
That said, if all I could play on it was NFS:MW, I’d be happy with my Vita. It’s just not a good console for PSP games.
Have both of you not turned bilinear filtering on for PSP games, then? It provides some anti-aliasing and smooths out the picture quality.
I disagree that PSP games look horrible on it. Both the Slim and the Phat have much better screens than all the PSPs did. The PSP-1000, for example, had a horrendous amount of image ghosting. PSP-2000 had washed out colours. PSP-3000 had the scanline issue. All of them hid the fact some games looked a bit jagged here and there due to hardware limitations, whereas because the Vita models have better screens it’s a bit more obvious. Not a big deal really. PS1 classics actually look better because the PSP’s limited resolution meant they had to be forcibly downscaled, whereas they run close to native resolution on the Vita.
I certainly think calling it a s****y PSP is a disservice since it can play all the PSP games with the right exploit(s), same with the PS1 if you stayed on FW 3.18 or below. What kills the scene is this kind of attitude when someone skilled like TheFloW does something really impressive and people just turn up in the comments section with the same old “Vita is dead” rhetoric.
What I think they’ve mean is that on Vita psp games are rendered in a native psp resolution and are then stretched to fit Vita’s screen which is quite noticeable and does not look good.
I got that, but I think bilinear filtering mitigates this and suggest that it didn’t look as bad on the PSP because all the screens were flawed enough to hide it. The Vita has a larger, nicer screen (even the fairly poor LCD on the Slim is better than any of the PSP LCDs, understandable given the age of the PSPs now) so any flaws are more obvious, but the fact colours are deeper, viewing angle is better etc has made – for me personally – the Vita a far better experience for PSP games than the PSP games themselves.
Anyone that thinks PSP games look poor on the Vita should try it through PSTV or on PC via emulator. No amount of filtering on the latter is gonna hide the problems when you try blowing it up to 1080p…
I’d love to see yifan lu’s thoughts on it.
Can any of there learnings from here, apply to the PS3 Super Slim? like the webkit exploit?
Totally different architectures, dude. No exploit from the Vita can be transferred to the PS3 and vice versa.
Hey, wololo. I’m interested in becoming an author. Just contact me by email
