Flashing OpenWrt FritzBox 3370

Installing and Using OpenWrt
6

I just installed OpenWrt 22.03.03 successfully using lftp following https://wiki.freifunk-dresden.de/index.php/Router_einrichten_AVM#Anleitung_f.C3.BCr_FritzBox_3370_unter_Ubuntu_.2F_Debian

Replace XXX either with hynix or micron, depending on your model cpu.

Steps:

  1. Install lftp
  2. Rename openwrt-22.03.3-lantiq-xrx200-avm_fritz3370-rev2-XXX-squashfs-eva-kernel.bin to mtd1
  3. Rename openwrt-22.03.3-lantiq-xrx200-avm_fritz3370-rev2-XXX-squashfs-eva-filesystem.bin to mtd0
  4. Create a separate file named adam2-commands with the following commands:
open 192.168.178.1
login adam2 adam2
quote USER adam2
quote PASS adam2
binary
debug
quote SETENV linux_fs_start 0
quote MEDIA FLSH
put mtd1
put mtd0
quote REBOOT
quit
  1. Change your local ip to 192.168.178.10
  2. Open a terminal where all three files are stored and run lftp -f adam2-commands
