Hi, I own several RM520N GLAP and by chance I recently sent the AT Command FASTBOOT. Ever since that moment the whole device disappeared and only the system device “Quectel PCI Express” remains visible in the device manager. No Com Ports at all. I assume it is stuck in boot mode.
Interestingly at the same time the Hardware-ID changes from PCI\VEN_17CB&DEV_0308&SUBSYS_520117CB
Impossible as I do not have any AT port connectuion.
Interestingly when I put the module in a USB to M.2 Adapter with a reset switch I can get randomly a Qualcomm Android USB Port (on a GLAP version!?) but I cannot do anything with this.
