Step by step guide for openWrt installation

Prerequisities:

  • Computer with LAN port
  • working Internet connection (for example via mobile)
  • If you don't have a Linux computer an USB-stick (at least 8 GB)

If you already have a computer with Linux and a working internet connection with it, jump to step 4.

  1. Create a working Ubuntu Live-stick according to this guide and shutdown your computer when finished.
  2. Start your computer with the stick plugged in. Ubuntu should now start. Click on "try Ubuntu" never ever install Ubuntu on your machine! You will loose all your data!
  3. Test you Internet connection in Ubuntu by opening a browser and go to github.com/majuss/easybox904.
  4. First of all we need to install the needed software. Open a terminal and enter: sudo add-apt-repository universe. Then run: sudo apt install git autoconf g++ pkg-config libz-dev gcc-multilib g++-multilib make automake gawk libtool libtool-bin bison flex libncurses5-dev imagemagick libacl1-dev libcap-dev tftp-hpa tftpd-hpa net-tools ssh bsdiff p7zip-full -y.
  5. Then clone the freetz repository: git clone https://github.com/Freetz/freetz.git freetz-devel.
  6. Change your working directory into freetz-devel with: cd freetz-devel and run make tools. If the make command does fail some requirements are missing, just google for the error message or open an issue. The compiling should take some time.
  7. After the tools were successfully build keep the terminal open and go to your browser. Visit the website: https://ftp.avm.de/fritzbox/fritzbox-7490/deutschland/fritz.os/ and download the latest image.
  8. We now extract the download image with multiple tools. First of all we untar the image: tar -xvf FRITZ.Box_7490*.image ./var/tmp/filesystem.image --strip-components=3 then we will unsquash that with: freetz-devel/tools/unsquashfs4-avm-be filesystem.image -e filesystem_core.squashfs then move the extracted file with: mv squashfs-root/filesystem_core.squashfs . delete the empty directory: rm -rf squashfs-root and extract the fs again: freetz-devel/tools/unsquashfs4-avm-be filesystem_core.squashfs -e lib/modules/dsp_vr9/. You can now find the modem-firmware in squashfs-root/lib/modules/dsp_vr9. We only need to patch it with: cd squashfs-root/lib/modules/dsp_vr9/ then: bspatch vr9-B-dsl.bin vr9-A-dsl.bin vr9-A-dsl.bin.bsdiff and bspatch vr9-B-dsl.bin release-vr9-B-dsl.bin release-vr9-B-dsl.bin.bsdiff. Congratulations, the hard part is done.
  9. Now we can flash the OpenWrt starter-image to the EasyBox. Download the latest starter-image (fullimage) from here
  10. Also download the most recent firmware image from here (last confirmed working is 2019-02-07).
  11. Now pull your LAN cable from your linux machine and disable WIFI. Click the grid icon in the bottom left corner of your desktop and enter settings to open the system settings. Then in the network tab click the gear icon behind your eno1 interface. Then go to IPV4 and choose manual. Enter 192.168.2.100 as IP and 255.255.255.0 as netmask, leave everything else blank. Turn the interface off and on to reload the settings.
  12. Now run: sudo cp Downloads/fullimage.img /var/lib/tftpboot in a new Terminal window to copy the firmware image to the tftp-directory (close the old one).
  13. Connect your EasyBox (yellow port) with your PC with a LAN cable. Turn the box on while pressing the reset button. Release the button after 5 seconds. You now should see the red recovery screen. When it states that rescue process is complete, turn it off and on.
  14. Change the IP addres of your computer to 192.168.1.2 (see step 12 on howto) and the gateway to 192.168.1.1. Always check in the terminal if the IP was really set successfull with: ifconfig. If it wasn't close and open the settings menu again and turn off the LAN and turn on again til the IP was set.
  15. Now open a browser and browse to: http://192.168.1.1 (mind the http!) click the Browse button and choose the openWrt-sysupgrade.bin_smp from your downloads directory. Click Flash Image and wait. Then on the new site click Proceed. The router will now flash the firmware image. Wait 5 minutes and then open the website https://192.168.1.1 in a private window of your browser to avoid caching problems. He will tell you that the connection is not secures. Just hit Advanced -> Add exception -> Confirm Security Exception.
  16. You're now on the openWrt webinterface. Just hit the Login button.
  17. Open a terminal and run: scp freetz-devel/squashfs-root/lib/modules/dsp_vr9/release-vr9-B-dsl.bin root@192.168.1.1:/lib/fw.bin this copies the modem-firmware which we extracted from the Fritz!Box image to the EasyBox. Now run: ssh root@192.168.1.1 type yes and hit enter. You now are connected to the EasyBox via terminal.
  18. Run: vim /etc/config/network and scroll with the arrow keys to the section: config interface 'wan'. If you're not already in INSERT-mode just press i. Enter your ISP-login to option username. For Telekom customers it is: [Anschlusskennung]#[T-Onlinenummer]#0001@t-online.de and your password into option password. Also set the ipv6 option at the bottom to 0, and the ifname to dsl0.7. Then comment out the complete section config interface 'wan6' like so:
#config interface 'wan6'
#   option ifname '@wan'
#   option proto 'dhcpv6'

This disables IPV6 completely which is not needed in private networks. Then scroll to the bottom and paste the following switch config:

config switch_vlan
        option device 'switch0'
        option vlan '7'
        option ports '4t'
        option vid '7'

Add ths line to config dsl 'dsl':

        option firmware '/lib/fw.bin'

Exit vim by pressing esc and then :wq and enter. Then type the command passwd root and enter a new password for your box which is also used in the webinterface. Now simply type reboot and hit enter.

  1. Your easybox is now successfully setted up. You can reach it's webinterface at https://192.168.1.1

Since the firmware for the EasyBox modem (lantiq xrx200) is closed source and licensed I'am not able to upload it here. We will extract the firmware from a firmware image of a Fritz!Box 7490 (If you want another firmware, check this page: https://xdarklight.github.io/lantiq-xdsl-firmware-info/)
