Because legacy repacks contain modified configuration files ( .inf ), Windows 10 may block them due to a lack of a modern digital signature.
The biggest obstacle is that and the laptops that originally housed it, like the HP ProBook 6450b and 4520s. This leaves users in a difficult position, as HP’s policy has been to stop providing driver updates for these older business notebooks before Windows 10 was released.
Here’s a step-by-step breakdown of the method from a real-world user who found success on a similar Gobi 2000 module.

Right-click the installation script (usually named install.cmd , setup.exe , or DPInst.exe ) and select .
Run sp51022.exe . It will extract its contents to C:\SWSetup\SP51022 by default. A command prompt window may appear and disappear—this is just the extraction process in action. If the installer launches automatically, close it. We do not want to run the installer.
Here are the most effective, community-proven methods to install the driver. Here’s a step-by-step breakdown of the method from

A repack driver is a community-modified or custom-packaged installation script (often built using advanced installer tools or simple batch scripts) designed to bypass legacy OS checks. A proper repack includes:

The HP un2420 relies on a dynamic firmware loading architecture. Unlike modern cellular modems, this card does not store its operational firmware permanently. Instead, every time the computer boots, the driver must inject specific carrier firmware (such as AT&T, Verizon, T-Mobile, or Generic UMTS) into the module.
Run the executable. It will likely throw a compatibility error and refuse to finish the automated setup.
If the device still has an exclamation mark, manually update the driver: right-click the problematic device -> Update driver -> Browse my computer for drivers -> Let me pick from a list of available drivers on my computer . Then, select the appropriate driver from the list.
Remember the golden rules:
