On Windows 10 and the Vita is on 3.35. I want to update my vita to the golden fw. Installed QCMA and usb K driver and ran QCMA. Saw vita, tried to update via pc ... C0-11264-4 error after 20 seconds. Tried switching k driver via zadic guide here ... and same result. Rebooted machine, uninstalled QCMA, Rebooted once more ... Installed QCMA and switched drivers via above method ... got the same same error when trying to update or backup content. Driver seems fine since it pulled down my psn nic so the connection was made. Maybe the driver is crashing partly in or something? After I do this, I see the content manager icon blinking so I know a good connection is made ... Hard to get QCMA to reconnect unless i reboot. What else can I try ?
