3. Pre-Installation Checklist

• Identify correct hardware version – Check label on router: E1200M V1.0, V2.0, etc. Using wrong firmware = brick.
• Download official firmware – From Tenda support site or verified backup. File extension should be .bin or .trx.
• Wired connection – Use LAN port (not Wi-Fi) to avoid disconnection during flash.
• Static IP on PC (for TFTP methods) – e.g., 192.168.1.100, mask 255.255.255.0.
• Disable firewall/antivirus – May block TFTP or web upload.
• Power backup – Avoid power loss during write (risk of permanent brick).
