⚠️ Crucial Warnings Before You Start

1. Do not interrupt power: If the power goes out during a BIOS flash, the motherboard will be bricked (use a UPS if possible).
2. Check your specific version: H61 motherboards often have multiple revisions (e.g., Rev 1.0, Rev 3.0). Flashing the wrong revision file can destroy the motherboard. Check the print on the board itself near the CPU socket or RAM slots.
3. Beta BIOS: You mentioned "full" update. Often, user-made or "beta" BIOS versions found on forums are modified to unlock hidden menus (like overclocking options) or support newer CPUs. ECS does not officially support these. Proceed with caution if you are downloading from a third-party site.

Stability Check: Do not update if your system is running perfectly unless you need specific new CPU support.
