🔄 How to Flash (Working Procedure)

1. Check current version
   http://192.168.1.1 → Login (admin/admin or telecomadmin/admintelecom) → Status → Device Information.

2. Set up TFTP server (e.g., TFTPD32) on PC at 192.168.1.2.

3. Backup current firmware (via telnet/ssh):

   back up flash by tftp 192.168.1.2 0x2000000 0xF00000 wholeflash.bin
   

4. Upload new firmware (web method – safer):

   • System Tools → Firmware Upgrade → Select .bin file.
   • Wait 3–5 minutes. Do not power off.

5. After flash: Factory reset (press reset pin 15 sec). Reconfigure GPON SN/LOID.

Method A: Web Interface (For .bin or .bin.gz files)

1. Disable Firewall & Antivirus: Temporarily turn off Windows Defender or third-party AV. They sometimes block TFTP or HTTP uploads.
2. Log in as Super Admin:
   • URL: http://192.168.1.1
   • User: telecomadmin
   • Password: admintelecom (or nE7jA%5m – common backdoor). If these fail, your ISP changed it. You may need to reset the router (30-30-30 reset).
