Trouble getting TN-V4 to work? Solutions here!
A few hours ago we released Total_Noob’s eCFW for the Playstation Vita, TN-V4. As the release was compatible with more than 40 exploitable games if you include all regional variations, it was impossible for a handful of beta testers to find all problems, so we were bound to have trouble at the initial release.
Some people have reported issues, and I hope to gather them here, and (hopefully) solve some of them.
Errors starting the Megamix exploit (error C1-2858-3)
In some cases, it seems switching your console language to English will fix the problem. I’m sure a more compatible version will come soon, but in the meantime give this a try
Errors with the King of Pool Exploit (EU)
Qwikrazor87 has a fix for this issue, check this thread with download link
TN-V4 Doesn’t work AT ALL on Firmware 1.xx and 2.0x
Reports are coming that TN-V4 doesn’t work at all on older firmwares right now, but Total_Noob is working on a fix
The Loader for game XXXX is not available anywhere?
A few of the loader games were missing from the repository initially. Please check our TN-V Loader download page for up to date links. In particular, hackinformer has been adding missing links today, for games such as Arcade Darts, pawapuro, etc…
I Don’t know how to run the exploit for game XXXX
check The Z’s Youtube channel, he has videos for most of the exploits, showing how to run them.
I Don’t know how to install homebrews/emulators on TN-V4
- Check TN-V4’s readme (“How to install Zips” section).
- If you didn’t figure it out with the above, check this tutorial. It was for the UNO exploit but is still valid today
- Still need more help? Ask for help on our forums!
You can get “ready to install” zips on SMOKE’s gigantic homebrew thread here. There’s usually a bit more work involved for emulators, as you will usually need to add roms by yourself in the Zip. Do *not* ask for roms or bios files on our site!!!
Also check trebuin’s guides here
I Don’t know how to install ISOS on TN-V4
- Check TN-V4’s readme (“How to install ISOs” section).
- If you didn’t figure it out with the above, check this tutorial. It was for the UNO exploit but is still valid today
- Still need more help? Ask for help on our forums!
The most common mistake with ISOs is that people forget to uppercase their ISOs before copying them to the Vita (you guys are such noobs… but I love you anyway… no, really if you still make a mistake like that with your file names, given that we’ve made that clear with pretty much every.single.release. for the past 10 months, you’re really not paying attention, so please focus. Hackers spend months of their time making these hacks for you, the least you can do is spend 5 minutes actually reading the f##ing readme.). The filename must be less than 8.3 characters, ALL uppercase:
GAME.ISO is ok
Game.ISO is not ok
GAME.iso is not ok
SUPERLONGNAME.ISO is not ok
GAME.ISO.iso is not ok (typical if you hide filename extensions on Windows)
I have another problem and you didn’t mention it here!!!
First of all, make sure you REALLY read TNV4’s readme. 99% of the issues are solved for people who carefully follow the instructions.
If you still couldn’t figure out your issue, go and check the TN-V4 Bugs thread here, and/or ask for help on our forums



Any clue on how to install CXMB? I figure that as soon as you open up the exploit savedata folder, I put my cxmb.prx and cxmb folder containing the vsh.txt inside there? Thanks.
Guys I have an idea on how to get megamix or reborn even after it is deleted.Now any person who has downloaded the game before it had been deleted can upload the backup in network
Please stop speaking…
First, you gotta rename all related files to caps and keep the name short (e.g. CXMB.PRX).
Then install PSP Filer from http://goo.gl/06pfmt, transfer it to the exploit savedata folder, along with your ctf file (same naming rule applies), and then install and run PSP Filer from the CEF.
Then from PSP Filer, shift/create the cxmb folder in ms0:/ and place the CXMB.PRX inside
then shift the VSH.TXT to seplugins folder located inside ms0:/ (create the folder seplugins if its not there)
as for your ctf file, move it to ms0:/PSP/THEME (you might need to create the folder again)
And you’re done 🙂
i use ftp sometimes if i feel lazy and its easy.connect wireless to ur laptop but i think it takes a little longer to transfer the iso’s
I do the same because CMA is annoying. I have to restart my Vita every time I want to transfer something. The first thing I installed to TN-V4 was VitaFTP lol.
Wifi in the vita like 150mb I think… Wifi cloud storage…And laptop .. Can laptop be corei5 or amd run emu ps3 stream games to vita.?
I searched but get many different answers, what tool is the best for converting psx eboots to iso that will work on this release?
Think one that works with the psp…
Just to confirm:
Works just fine on 2.12 with GOLOR Exploit.
Just need to follow the instructions properly and it will work.
so the same steps apply if you already have a vhbl installed? I too have GOLOR on 2.12 and not sure how to go about installing TNV4.
To avoid any confusion:
Just delete your VHBL SAVE.
Then download this one: http://hackinformer.com/TN-V/GOLOR_US.rar (for US game)
Or
http://hackinformer.com/TN-V/GOLOR_EU_v2.rar (for EU game)
Get TN-V4:
http://wololo.net/downloads/index.php/download/7672
Download 660 PBP: http://wololo.net/downloads/index.php/download/947
(choose the PSP 1000/2000/3000 version, *not* the PSP Go version)
Rename the EBOOT.PBP to 660.PBP
Extract the savedata from the TN-V4 loader of your game on your hard drive, in your CMA’s PSAVEDATA/xxxxx folder (where xxxx are a bunch of letters and numbers).
Copy TN.BIN, FLASH0.TN, and 660.PBP in the game’s savedata folder (where you can find ‘H.BIN’)
Copy the game’s savedata to your Vita, using OpenCMA
Run GOLOR Game
On the first boot, the recovery menu will appear automatically.
Select ‘Advanced ->’ menu and then select ‘Install 6.60 files’ (this step is only needed if you’ve never used TN-V4 before).
Enjoy the install progress.
After the install is done, go back and exit the recovery menu.
Enjoy TN’s awesome work.
Worked for me on first try.
Adding ISO games is super easy.
Just rename them to all caps and make sure there noire then 8 letters.
Example: HEROES.ISO
You can keep adding games to your GOLOR save folder and transferring to your Vita.
When prompted to override your old save file choose yea. (Just don’t delete TN-V files)
After each install of the game delete them. Then do the proses again.
Enjoy!
*noire (was a typo)
It should say: ‘No more then’
iOS Auto-correct thinks it’s wise..
Worked for me first try too – this is great! Now I just need to learn how to install the SNES emulator and software in this environment. Ive never used it before but mod linux android systems so it should be easy.
Nicely done..really appreciate the reply, thanks.
Hey wololo, can you or TotalNoob help me? I’m having the C1- 2858-3 error on my exploit. It’s running TN-V4 using the Megamix exploit. I just followed the instructions and tried the exploit out. The screen remained green then gave me the error. I tried switching languages between English for the UK and US but it didn’t work. But still, the green screen itself is a sign of help. Fortunately my device wasn’t bricked or anything, just the game was exited.
same here
I want to play GBA,NES games please guide me thank you very much.
I’m trying to load it up for fieldrunners but I keep getting the error c12858-3. My language is set to US english. I think i have everything right.
heres a pic of my folder.
http://i.imgur.com/TgDORTv.png
Can someone take a look?
please read this thread,
wololo.net/talk/viewtopic.php?f=56&t=35899&p=316724
it was happening to most of us, using the fieldrunners exploit, the big mistake was trying to be redundant in order to avoid failures in execution of TN-V4
just do it as our brother veridiux said
1. Copy FIELDFIRMWARE & NPUZ00014 to your PSAVEDATA folder
2. Place TN.BIN, FLASH0.TN, and 660.PBP in the FIELDFIRMWARE folder (to test ir just put those, not the PRX plugins)
3. Copy these to your Vita through OpenCMA
4. Run Game normally.
5. Go into TN-V4 Configuration menu, and install 6.60 files
and voilá
you’re good to go
Hope this helps
Thanks man! It works you are a lifesaver!!!!
nvm i got it thanks tho
Need help
Have 2 vitas
One 2.12 tnv4 runing Invizimals iso backup it crash whem camera is needed
On the other one 3.01 101 works just fine
I’m sitting here, installing Crisis Core (that I ripped from my own disc about an hour ago!) and have had no problems so far.
Thanks for posting this FAQ, wololo, this is my first kernel exploit, and it’s much smoother/easier to do anything than I thought it would be.
I need major help. I am on 2.61 and have had Fieldrunners for a while nowwith VBHL. I installed Tn_V4 today and all was good but I was messing around and accidentally deleted Fieldrunner from my Vita. Did I screw myself that easy? How do I get Field runners back?!. I still have it in a bubble on my PS3 but I can’t do anything since Charles proxy does not work anymore. Please help me. I am kicking myself for such a simple mistake…..
Just restore the backup of your memcard with the exploit game using openCMA.
You DID make a backup of your precious exploit game, right…?
You can do this with the OpenCMA trick. You connect your Vita to your PC with Airplane mode on, then disconnect the cord physically and plug it into your PS3. This will bypass the firmware check on the PS3’s side, letting you transfer any compatible “bubbles.”
But I suggest you back it up on your PC as well in the future.
How long till the next exploitable game to be announced that will be on the AU PSN.
Estimated guess anyone? Wololo can you please help?
My favorite part is not that tn-v4 has been released, it’s the bolded part of this blog entry lol.
One wanted one 4×4 saving would have been fun.. My bad people wanted like one hybrid vw4x4..
And they was busy since win7any way it’s jus an issue now cuz people ask not to jus estrirk..0dd system not that tweak out… But yea so the iPod thing Microsoft did that like the iPod that should work fine with the Xbox one….
Ummm…Stop
Ummm…Stop
But I would have taken the pill if I was Neil Neil in speed was cool but Neil with the cyborg dolphin was way cool smart how a fish like creature could swim the Internet stream and data waves better then a human was to be like a wow or sword art online…..
Yea one read me was like not all in English so I had to guess what to do think was the ocm but good I remember how to do it with the older versions.. Well first it was a dl that I jus can paste to the comp… Jus saw txt so was like this look cool…. On Xbox now since ps3 needs work..
It’s working for lots of people. If you have something better, feel free to share it for free like these hackers did. We are not getting any money when you buy an exploitable game.
Just ignore ungrateful kids wololo.
If not sure installing iso/zip files ok or not, after trasfering files to vita, before testing inside tn-v4, you could enter VITA->PC options and check PSP savedata file size, anything invalid naming ones could be found that the filesize is not equal with your file
I think this may filtered by $ony with invalid format :D, so following the instructions of file-renaming rules 😀
How long till the next exploitable game to be announced that will be on the AU PSN.
Estimated guess anyone? Wololo or anyone can you please help?
I don’t have any information about it but still wanted to post this anyway: “Soon™”
: D
Yea I would hate not to have an exploit that runs on 3.00+ or one that does work with the ps4 so the xboxone facial voice recognition anything like the Facebook one think funny how the went to a single hd cam wen 3ddual would have done so much better fo deep perception… But I guess is better to have a sharper image for facial profile setiing up an Xbox one account…
Stop it with this garbage…
Well presumably they’re going to try to get it out before the next Vita update, so something like “ASAP.” I recommend regularly checking the site and forum.
But no one can give you detailed information, because no one actually knows when the ninja release will begin or how long it will go on until the public release. (other than presumably the new exploit’s author and wololo)
idont get it about downloaded zip iso games.
http://www.youtube.com/watch?v=p8smq75-TwQ
That should help with installing ZIPs properly. As for ISOs, the instructions are in the readme and on hackinformer. Just follow them exactly as they say, and it should be simple enough. Also, take special note you follow THIS.
“The filename must be less than 8.3 characters, ALL uppercase:
GAME.ISO is ok
Game.ISO is not ok
GAME.iso is not ok
SUPERLONGNAME.ISO is not ok
GAME.ISO.iso is not ok (typical if you hide filename extensions on Windows)”
Nobody MADE you buy any games. Nobody MADE you wait -as you say, “a year”- and because the files for TN-v4 were provided to the masses for free then I think you should…
Chill out.
They owe you nothing and yet they are giving you stuff for free so relax and learn a few things. Like consideration, respect, and patients for instance.
It doesn’t do any good to yell at people that are giving you help and not asking for anything in return. If you anger them enough they will just quit helping all together.
How would you feel, spending months of work on a project that you are doing without pay and when finished you share it with the world for free.
Only to have some impatient, spoiled kid screaming at you and not even provide any insight into what the problem is.
Yeah Patients (It’s patience)…lol Just kidding around. But seriously. Completely agree. People need to stop being so whiny. Seriously wish I could figure this stuff out myself, and I’m just grateful people like wololo, and this site, exist at all. Otherwise, I would have nothing at all. Thanks to everyone that makes this at all possible.
It can be hard to get it to work, of course, but as long as you’re careful and you take some effort learning about it, you’ll definitely appreciate it.
Just make sure to backup everything all the time, and don’t make any silly mistakes once it’s working. You will feel silly having said this about TN (and wololo et al) once you get it working and realize it makes your Vita twice as awesome and enjoyable.

i made a video on the install

Noob as heck, better die
With firmware 3.01, it works very well. I had no problems. Just observe the operating conditions and installation .
Anyone else is having trouble running the SNES9x TYL 0.4.2 emulator? It starts ok but keeps crashing when loading a rom. All the other emulators run fine BTW.
to all guys who make homebrew possible on vita, u are great! unfortunately sony doesn´t see so. 😉 but who cares? 😀
Think Sony more hardware vita CPU connect ….
I forgot to tell I’m on the Megamix exploit on 3.01.
Wy u should have gotten the games before the 1.81 wy I need a vita under 1.81.. Patches make harder for outher exploits to work…. UNO if u had a ps3 cf u could play the psp games wish I had a ps3 with cfw but I got to fix my ps3 power suply.

how to install plugin?
hi Wololo, you mentioned that there was a new Urbanix exploit for pre 3.x firmwares. do you know if that ever got released?
Just wondering, is it possible for USB connection when on PSP Home Menu? I tried it, but the error occurred. I hope it is working so I can transfer the game and any homebrew files easily.
Any homebrew application that can be used easily for file transfer like ISO and PBP file format?
Nope not possible. The easiest way to transfer is through VitaFTP.
I tried with VitaFTP. It works when transferring, but just a bit slow, so that’s kind of let down to me when transferring big ISO file.
Once the new firmware is up, I would probably not using CMA to transfer the file using USB since it would require new update, so for now I use this opportunity to transfer any wanted ISOs to save data then (using the method from last UNO exploit).
the open cma r6 its not working from now!
My problem is after all worked well on 3.01. I decided to free up space on this 32gb memory card. I deleted some unnecessary games on vita homescreen. Now back on xmb my game column has undeleteable corrupted data areas. How do I remove them since hide em in vsh recover Does not work?
Do I have to copy the whole save file with all the things I want to have in it(backups and homebrew) every time I want to just add something in there?
I see that homebrew can be installed, but what about backups? Though it is not a big problem for me, I could see it as cumbersome if you have a small memory card and had to switch the stuff in it more often.
