Hacking Ps Vita to PC transfer issue

[hoist20032002]

As the title says, I've been working on this for hours so I can save a PSP game on to my PC through CMA. Any ideas on how to fix? It keeps giving me the same "Could not connect to the PC" error. I'm on OFW 3.50 and not wanting to update.

try using Qcma and vita update blocker v1.2 also try a different usb port and if that doesnt work it probs means your usb cable is damaged but if you can run homebrew on your vita then just use vitaFTP to transfer the psp games over if your referring to isos if your referring to backed up psp games your just gonna have to do it over the wifi

It worked until my Vita died while backing up my psp game to my PC and now I get this error code (NW-10743-5) every time I use wifi...
