How did you solve that problem? I'm using QCMA and my Vita on 3.18 connects to the PC, but as soon as I want to refresh the database, it says "No PSVITA found".
I can't use the regular content manager, because even in flight mode on the PSVITA and offline mode in QCMA activated it asks me to update.
For clarification, I'm trying to use the package installer trick to get PSM1.14 on my PSVITA, because I don't have a second one. Not sure if that's even possible, though.
I've been accepted for a license, so at least that's no problem.
