Just FYI for anyone having this issue with the FTP refusing connection. I was using FlashFXP and even tried WinSCP but the connection was still refused. until i figured out that, after i pressed 0 for the ftp server to run in the background, the server didn't! it closed after i pressed 0. I figured this out tried to connect to the psvita's FTP server, with the message still on the screen by pressing "select' SEEING THE ftp SERVER INFO ON THE SCREEN, then i tried to connect and i was successful! So keep that message up after you press select and don't press 0 to close it to run in the background, because it doesn't, it closes the server instead. @ : o O ) >
Update:
Never mind this post. I was pressing o, instead of x. Hence the reason why the server keept closing. @ : o / ) >
