Issue: When trying to install a firmware image via TP-Link WebGUI, I get the following error:
Error code: 18005, Upgrade unsuccessfully because the version of the upgraded file was incorrect. Please check the file name.
Root cause: TP-Link “Region locked” firmware. This firmware is checking for a specific region signature when flashing.
