so I followed the instructions on how to fix the QMI_ERR_ACCESS_DENIED through QPST until i stumbled upon an issue. When I go to /nv/item_files/modem/qmi/ there is no uim dirrectory, only cat. I attempted to create the file but unfortunately, I received an error message saying that it cannot be created, but when I tried to create a directory that was named anything else, it was okay.
I got the phone to connect to my RNS 510, but it said there was no Sim in the phone
