Instructions to upgrade your COBRA equipment using COBRA Reprogramming Software


Step 1: Download the latest version of the COBRA Reprogramming Software

The COBRA Reprogramming Software, also known as CRS, can be downloaded from https://www.cobrafiringsystems.com/download_crs

During the installation process, a warning may be presented that this program has not been checked by Microsoft and may cause harm. This notification is being displayed because the COBRA Reprogramming software has not been signed by Microsoft. The software not being signed does not affect the security of the software, and you are safe to complete the installation.

The installation can be completed by pressing "learn more" followed by  "Run Anyway".
