Last i knew, pro online does not work with vita...but i have been out of the loop for a while so that might have changed...i dont even know what vita adreneline is though, i assume its actual vita native cfw finally....ill do some research and get back to you
Edit: after reading up on it, adrenaline is another eCFW...i think ARK was the only ecfw that was working on PRO support since it uses Coldbird's source code as a base, and as far as i know they hadnt got it working yet
