I’m having a hell of a time trying to update the firmware of my EM7455 on my Dell Latitude 5490. Device Manager shows it as a DW5811e Snapdrgon X7 LTE.
modify registry key “HKEY_LOCAL_MACHINE\SOFTWARE\Sierra Wireless Inc\Firmware\GENERIC” to “002.045_001”.
confirm the firmware exist in the folder specified in registry key “HKEY_LOCAL_MACHINE\SOFTWARE\Sierra Wireless Inc\QDL\FirmwareLocation”. If not, you may need copy the .cwe and .nvu file to that folder.
restart computer.
after step 3, see whether firmware upgrade happen. if not. let me know. I may need you capture some logs.
@jenova314 Seems your driver package does not include any firmware. Can you help to setup TeamViewer session so that I could take a look remotely?
Before that, let me know where is your fdt2.exe and .cwe .nvu firmware located.
