fwupdtool [command] [options]

fwupdtool is a low-level firmware manipulation tool that works alongside fwupd. Unlike fwupdmgr which handles automated updates from LVFS, fwupdtool allows manual firmware operations including installing local firmware files, parsing firmware archives, and device verification.
This tool is primarily used for debugging, development, and situations where firmware must be installed manually from a vendor-provided file rather than through the LVFS repository.

Manual firmware installation bypasses LVFS signature verification. Only install firmware from trusted sources. Incorrect firmware can brick devices. Most users should prefer fwupdmgr for routine updates.

fwupdtool is part of the fwupd project, created by Richard Hughes in 2015. It serves as the development and debugging companion to the main fwupdmgr tool.
