had replied with nothing but a masked Mega.nz link and a warning:

“Check your hardware version before flashing. There is no turning back.”

Elias paused, his mouse hovering over the download button. He looked at the router—the F670L, a sturdy dual-band workhorse. He knew the risks. One wrong file, one power flicker, and the gatekeeper would become a brick. With a steady breath, he clicked.
