The InFocus M680 is a 5.5-inch Full HD smartphone with a slim metal build and dual 13MP cameras. While it won praise for its display and design, owners often report battery drain, quick overheating, front camera over-softening, and lag or “bricked” boot after failed updates or custom ROMs. Official firmware helps solve these issues by restoring the original system, repairing stuck logo or softbrick, and bringing back lost or buggy features.
