EM120R-GL (PCI-E), latest FW and FW update tool for Windows?

Hello, I have a Lenovo Thinkpad T14 gen 2 (Intel) laptop. Just bought the EM120R-GL PCI-E modem for it specified by Lenovo. It works well under Windows 11 but constantly disconnects and reconnects under Kubuntu 22.04 LTS. Presumably, this could be solved by the latest firmware but I’m not sure how to install it; I read it’s best to do it under Windows. Currently, I’m using the 1.0.0.39 driver (nz7wj13w.exe from Lenovo). The driver package seems to contain some kind of firmware and an executable named FWUpgradeTool_PCIe.exe but it does nothing when executed directly. The parameters from Windows Settings are as follows (parameter names translated back to English):

Manufacturer: Quectel
Model: Quectel EM120R-GL
Firmware: EM120RGLAPR02A03M4G_01.001.07
Network type: 3GPP
Data class: UMTS; HSDPA; HSUPA; LTE

Could you send me links to the proper firmware update tool for Windows and the latest firmware package for the modem?

Hi, Sir
I will send the latest firmware version to you via Email. Thx
For upgrade tool, you may go for following link

Thank you very much! Which of the files in the Toolkit section is used for flashing the firmware on Windows?

The QFlash can be available

Tried running QFlash on Windows 11 with the firmware file you sent me (EM120RGLAPR02A08M4G_01.001.01.001.zip), this is the error I’m getting on the file:

“No Key(json,blf) file is found, this zip file maybe a invalid zip or you downloadmode is not right, please check it.”

The ZIP file itself is technically fine, I can unzip it and see the contents.
