well after long hours and countless tries i got this to work with no problems ----
1st ---you need a jailbroken ps3 with something that does retail pkg's ---i have a ps break dongle 1.0 and even thou it says it is upgradeble --it is not ---unfortunatley it is the replica , so i can't answer on the other ps break dongles --so i got ahold of a trusty ti84 and installed ps groove and hermes payload with retail pkg support ---it works like a charm
2nd ---put the pkg's on a flash pen and install on the 3.41 when it is jailbroken ----you need to install eash map pack and i just named them mappack1-2 or 3.pkg----then you need to ftp them to your pc install your patches-----then data transfer them to your 3.50 and go into ps store and start the download for each mappack ---put them into background ---go out to download managment and cancel them ---you now have the mappacks working on you online ps3 ---of course you have to have them in your ps store downloads ---and thats how they get activated -------
