I use below method with a success:

 

FINALLY – played around with this for ages – and finally made the FW update happen.
I use a Lenovo X1 Carbon (20A7) and have not been too happy with the modem performance.

Tried modifying the xml files as instructed, but no firmware update dialog appeared.

Zipped the latest generic firmware .fls file from ProgramData with a modified xml-file, but received the “ERROR: Firmware v1616.01 is not intended for this model of the device.” error message. downloaded all the firmware packages from this site – but same result – with our without SIM made no difference (except for the 1349 build that I could re-flash from the tray icon program (but still 1.1 and same issues as always
)).

Finally I decided to return to CLI and read the prompt

Stopped FirmwareApp.exe (running in tray) and did (this one without a SIM inserted):

C:\Program Files (x86)\Sierra Wireless Inc\LENOVO MBIM Toolkit> FirmwareCmd.exe -i

Signed up just to say thank you!

Iv'e spent about a week trying different flashing methods for my EM7345 on T450 , nothing worked except what you posted.

Also it didn't flash WITH a sim, i had to take it out, weird. (all other methods require a sim inserted oddly enough)

Anyhow, cheers!
