(adsbygoogle = window.adsbygoogle || []).push({}); okay, i get the same question a lot, so i'm gonna answer it for all of you guys !

items required:

3.41 PS3 (with JailBreak obviously)
3.50 PS3
PC
ethernet cable (CAT5e / UTP / whatever you wanna call it)

software needed:

on 3.41
FTP server (can be done with Comgenies awesome file manager but i won't explain this here..)
IMPORTANT: if you want mods on the map packs, you will NEED them installed on this PS3 ! downloading them on your 3.50 from PS Store will overwrite the modded patch

on PC
FileZilla (or any FTP client) configured to connect to your PS3 FTP server

THE INSTALLATION

on your 3.41, make sure you have the 1.07 patch installed
you can do this 2 ways:
1. make sure you have a working internet connection on your 3.41 ! start WITHOUT jailbreak, insert the WAW disc & it'll prompt you with an update, install as you would do on 3.50
2. start WITH jailbreak (make sure you have at least PL3), download the 1.07 patch (You must login or register to view this content. OR You must login or register to view this content.) & install like you would install FTP server

Now we can get started with transferring a MODDED patch!

1. start FTP server on your 3.41, you'll see your ps3's IP address, write it down !
2. open FileZilla on your PC, type the IP address (you just wrote down) in the 'quick connect' address field & press quick connect (enter username & pw if you don't use BlackBox FTP)
3. in filezilla, in the right side, browse to hdd0/game/*your disc id*/usrdir/english/ (obviously replace the DISC ID with BLES00354 or BLUS30192)
4. on the left side, browse to the folder where you have the modded patch.ff (& PATCH.FF ONLY !)
5. DRAG it into the right side
6. It'll prompt you a warning that the file already exists, click OK (it should've highlighted OVERWRITE)

now you have a modded patch for the first map (& some patches the 2nd map as well, as it's in 1 file)
you COULD now transfer to your 3.50 & play these mods online.. although a lot of people want mods on the other maps as well so...

ONLY CONTINUE IF YOU HAVE THE MAP PACKS !
(If you have purchased the map packs legit in PS Store but they're not on your JailBreak PS3, read You must login or register to view this content. first !!)

once you have the map packs installed, it's basically the same to get a modded patch on, but you need to drop the file in a different folder:

Shi No Numa (nazi_zombie_sumpf_patch.ff) goes in 'hdd0/game/*DISC ID*/usrdir/english/dlcmappack2/english/nazi_zombie_sumpf_patch.ff'

Der Riese (nazi_zombie_factory_patch.ff) goes in 'hdd0/game/*DISC ID*/usrdir/english/dlcmappack3/english/nazi_zombie_factory_patch.ff'

important detail: i didn't come up with those names, 3arc did ! ppl ask me how to name the files etc.. i upload the files READY TO USE, no need to change names, no nothing.. drop it in the appropriate folder & you're good to go
so if you get stuck, browse your ps3 hdd in FileZilla & find the .ff file with the EXACT same name.. just overwrite that one & should work just fine !

I hope this helps & keeps my inbox from getting spammed as much..
if you need help, just post in this thread instead of sending me a PM !

there you go & thank you!

yours truly,

Karoolus

I hope you get it now..

Thanks for the guide.

Great, more things that I cannot do due to the updates.

good work and all, but everytime that i transfer the shi no numa/der reise patches, i cant play the maps, it shows as if i havent installed them. i'm doing this on 1 ps3. (downgrading and upgrading). anyone help? .

ACTIVATE the map packs in the PS Store..
won't work any other way

k thanks . i'll try it out right now. good job

I heard there was a way to install a modded map pack patch without the retail .pkg because due to my JB and the inability of it to update. I have the MPs purchased on my 3.50 and what are the default names for NDU zombies and the MP patch.
Thanks,
Uber
