Wavecom DWLWin 4.1

Wavecom DWLWin is a legacy Windows utility used to flash, upgrade, and recover firmware on Wavecom-branded cellular modules and modems. Aimed at technicians and integrators, it communicates with the device over a serial (COM) connection to:

• Load official firmware/application packages (commonly .dwl or .wpk files)
• Recover devices that only start in downloader/boot mode
• Erase, reflash, and verify memory images
• Read basic device information such as product identifiers and bootloader version

DWLWin was widely used alongside Wavecom’s Open AT development tools in service and manufacturing environments. Because incorrect settings or files can permanently disable a device, it should be used only with the exact firmware for the target module and with proper power and boot procedures. As a legacy tool, it may require compatibility settings or a USB-to-serial adapter to run reliably on modern Windows systems.

Wavecom DWLWin is developed by Wavecom. The most popular versions of this product among our users are: 3.1, 3.3 and 4.1. The name of the program executable file is Dwlwin.exe.
