Just for the record i bought BLUS31011 CP Edition from 3ARC = $197.00 ! I was only able to get paid DLC from PSN on OFW-431 + REX 421. Now for CFW 355 i wanted my DLC, i paid in blood for this game..
I forgot who said they could not get DLC working on different region.? Being i did it, i will just explain for those who want it on CFW 355 & failed.
Do not copy the entire "USRDIR" to do this.
Install both v102 patch 355 fixes "BLES01717"+"BLUS31011" for REX 421 use normal patch.
Install DUPLEX BLES01717 DLC & then start up MultiMAN OS.
Browse to dev_hdd0/game/BLES01717" & "BLUS31011" folders.. Now open 2 windows "side by side" & copy 1 File/Folder at a time.
The DLC installs extra language files, so this step is necessary. Copy the "English"+"French" folders from inside=> BLES01717/USRDIR <= Copy to "BLUS31011/USRDIR"<= Over wright both "English"+"French" folders.
The "BLES01717/PARAM.SFO+x2 selfs+EBOOT.BIN/ICON.PNG <=Leave them alone.
DLC folders copy from BLES to BLUS: BLES01717\USRDIR <="dlc0"+"dlczm0" to => BLUS31011\USRDIR <= "dlc0"+"dlczm0")
Next copy 2 edats "BLES01717/USRDIR" =>"dlc0.edat"+"dlczm0.edat" Copy them to BLUS10311/USRDIR <= "dlc0.edat"+"dlczm0.edat")
I fired up Black ops II BLUS10311 & the DLC is working. I verify it works on my CP edition or any Black ops with English/French.
You can probably extract some files & do FTP to be faster but i did it this way cause i knew the language folders had the extra DLC files i needed. So far it ok. If you have any problem. Try after doing this ,install my patch over the top of the files you copied so then the DLC few files will be different I believe they are all the same though for these to Regions.
If you have a game with English this will work as long as you play in English.. reason is the language for DLC only supports French/English so this is why it did not work for those why tried with a 1 language game. If your game has English & Spanish the DLC does not so = Black screen if you try to play in Spanish. You can probably modify the language in DLC to get this working for you.
You need official DLC with your language & replace the DUPLEX English/French with yours, if you have just 1 language. I would leave English in & try to change the other one. The reason i did it like this is i wanted to keep my game BLUS10311.
If any are corrupt please PM me about it so i know & i can re upload. If you are a Glitcher do not install this update. This update will only patch glitches you want. If you want it to fix issues, or other intentions.? Then it is for you CFW 341+ BLACK OPS 7 Regions v103 Patch Updates - No Passwords.
