Hi gbatemp! I'm a long time lurker, first time poster. I have a PS Vita on 3.55, and I'm having issues. I'd like to access the content manager but my PC (windows 8 btw) won't acknowledge it's there. Also yes I have tried QCMA and Open CMA R5. Neither of them will register my vita or allow me to copy any files. I've tried the update blocker, I can't access the psn store without the error (NW-10743-5). I fear if I can't get QCMA, or CMA able to copy anything, I won't be able to do the exploit. Should I just trade in my 3.55 vita and buy a new one hopefully on a earlier firmware?
