NOW TV configuration for Openreach HG612 + OpenWRT router

I am hoping to save a few hours for people like me who have a modem + router setup and switched to NOW TV ISP.

Extract Client ID and Vendor Class ID from DHCP handshake

  • Connect to the NOW TV router and select "WANOE only" from advanced > router mode
  • With a computer connected to LAN 2, using Wireshark, collect DHCP Client ID and Vendor Class ID (options 60 and 61) (1)
  • Convert those two values to hexadecimal

Configuration for HG 612

E3372s-153 from Stick mode to HiLink mode automatic installer

E3372s from STICK to HiLink mode installer

You need

  • curl, usb-modeswitch, grep, awk, sudo (not necessary, last step can fail safely)
  • balong_flash in $PATH ( https://github.com/forth32/balongflash.git )
  • atinout in $PATH ( https://github.com/beralt/atinout.git will work fine )
  • 2 files we flash (core sw update version 22.x, WebUI installer), we use these (you can probably use different balong-compatible):
    • core sw: "E3372sUpdate_22.298.03.02.965.BIN" / "E3372sUpdate_22.298.03.02.965.exe"
    • webui: "Update_WEBUI_17.100.06.00.03_Hilink_V7R2_9x25_CPIO.exe"
