How to intall Openwrt on FritzBox 4020

[mikii]

Hey geys,

I am new here and want to flash the Router FritzBox-4020!

I visit the https://openwrt.org/toh/hwdata/avm/avm_fritz_box_4020
and downloade the file.....
after reserach i found a fritzflash.sh for 4020

and here i am stock:

# ./fritzflash.sh 192.168.178.1 openwrt-18.06.2-ar71xx-generic-fritz4020-squashfs-sysupgrade.bin

Flashing image openwrt-18.06.2-ar71xx-generic-fritz4020-squashfs-sysupgrade.bin to FritzBox at 192.168.178.1

This script will flash a given image to mtd1 of a FritzBox device.

This process will take some time!

About 2 Minutes for a 1750E.
About 2 Minutes for a 4020.
About 5 minutes for a 4040.

If you want a status bar: Attach a serial to the device and look there.

In case this process has not terminated after 10 minutes:
 - Terminate this process first!
 - Powercycle FritzBox
 - Retry

(Note: Make sure that you connected the router on the yellow LAN ports and not the blue WAN).

./fritzflash.sh: 48: ./fritzflash.sh: ftp: not found
# PING 192.168.178.1 (192.168.178.1) 56(84) bytes of data.

You need to install a simple (cli-) ftp client on your linux system, on Debian based systems one option would be the ftp-ssl package (given that it couldn't even begin with the flashing in the absence of a suitable ftp client, it's safe to terminate the script).

If anyone might find themselves in a similar situation: There is a Python implementation which has no dependencies beside the core python3 (It even runs on Windows) I've written a while back: https://github.com/freifunk-darmstadt/fritz-tools/blob/master/fritzflash.py

fritzflash.sh was essentially a copy of the flash-script for the 4040 with adapted messages for other devices.

Documentation is available at http://www.fritzfla.sh
