How to use HP UN2420 (3G Gobi 2000 Modem) in non-HP Laptop with Win-7/8/10 32/64 bit...

I have been trying to setup cellular connection for my Vaio Z2 using Gobi 2000 3G modem (Mini PCI-e) for almost two weeks without any success. These Gobi cards available in eBay at reasonable price but many venders fails to mention the fact that they are indeed branded units. UN2420 is a such card with HP firmware built-in.

Once you install the card in the socket and connect the relevant antennae, you must see a new device included in the Device Manager under LPT/COM ports. It will be named something like “HP un2420 Mobile Broadband Module” and it will be flagged with yellow triangle to indicate that the correct driver not loaded.

At this point Gobi 2000 is waiting for the drivers to be loaded by Windows Services using “QDLService2kHP.exe” file.

Gobi 2000 Device drivers are available to download from many laptop manufactures support websites such as Lenovo, Panasonic, Dell, Vaio and Asus so on. But only driver works on HP un2420 is HP driver available in HP support site. But wait, this driver package will only install the driver for the “HP un2420 Mobile Broadband Module” and rest of the driver loading process will be halted as QDLService2kHP.exe will verify your laptop as a non HP product. So you don’t need to head for HP site right now as there is a workaround.

A smart gentleman from Poland named DjExit has a solution for this. He had modified the QDLoader QDLService2kHP.exe file not to verify the laptop brand in driver loading process.
