Assuming you can downgrade the firmware. The engineers probably thought of consumers trying to get rid of their malware, and design ways to make this difficult.
I know some products blow physical fuses when updating the firmware and if you go back to the old firmware it won't run when it detects the blown fuse.
You'd need significant electrical skills to restore/replace the fuse to the original state.
