Risks and Precautions

• Bricking: Incompatible firmware or interrupted flashing can corrupt the bootloader or kernel, rendering the device unusable.

• Security risks: Untrusted firmware may contain backdoors or vulnerabilities.
• Hardware variations: Same model number can have multiple hardware revisions; using the wrong image can be fatal.
• Data loss: Configuration and stored data will usually be lost; back up settings first. Precautions:
• Confirm exact model and hardware revision (label on device, boot logs).
• Download firmware only from trusted sources.
• Use wired Ethernet during flashing (never Wi‑Fi).
• Keep power stable; use an uninterruptible power supply (UPS) if available.
• Note MAC addresses and serial numbers if needed for ISP provisioning.
