I have my EM7430 on a M.2 NGFF to USB3 adapter. At first this device works properly, the blue LED on the USB adapter turned ON, and I can get 4G signal from it. But I could not find the COM port to perform AT commands.
The update failed because maybe it cannot find the COM port. But now the Modem does not work anymore. Windows cellular indicator showing that the device is plugged in, but no service available. Windows Device manager also still showing the network adapter DW5816e snapdragon X7 LTE. There is still no available COM port.
Hi here is a screen capture on the device manager. No COM port that indicates the Modem, but the GPS seems like to be working, I tried to open the Maps app and it can show detail location of the device.
There is an update, I tried to install it on a Windows 10 VM, and in the device manager, there is this indication mentioned below.
could it mean that the device somehow went to a some kind of DFU state and cannot go to a normal state?
