Apparently, to run SOCOM FTB2 Online you will have to update your PSP's firmware to 2.81. The UMD itself runs on 2.71 SE-B" without a problem, but when you try to access the Online Lobby, you are forced to download a "temporary" firmware updater file. Details are unclear but this is what the guy had to say:

| this file you have is the file you donload when you try go online in socom but after you download this the psp check if you have 2.81 to instal the update. So this is a temporary file note the real finished update. |
