New OpenWrt Installation on AVM Fritz 7312

AbDhops · January 21, 2020, 7:22pm

Hi All,
I have AVM 7312 with stock firmware, and would like to install open WRT on it. So far,

I am able to connect with Bootloader.
Download the require image.
However, here onwards I am lost. I am not sure which commands I should issue to flash this firmware.
I already had a look on generic flashing via FTP page, but not understanding from where I should get empty file or kernal image.

Your help is highly appreciated...

Many thanks.

Installation instructions for FritzBox 7312 (from git-commit)

To install OpenWrt via Eva bootloader, within the first seconds after
power on a ftp connection need to be established to the FRITZ!Box at
192.168.178.1 and the the following ftp commands need to be run:
  ftp> quote USER adam2
  ftp> quote PASS adam2
  ftp> binary
  ftp> debug
  ftp> passive
  ftp> quote MEDIA FLSH
  ftp> put /path/to/openwrt-lantiq-xway-avm_fritz7312-squashfs-sysupgrade.bin mtd1
  ftp> quote REBOOT

Thanks...
I am getting following error..

ftp> passive
Invalid command.

If I still continue,

ftp> put openwrt-lantiq-xway-avm_fritz7312-initramfs-kernel.bin mtd1
---> PORT 192,168,178,2,247,6
502 Command not implemented
---> STOR mtd1
425 can't open data connection

What about passiv? Seems like a typo...

AbDhops · January 21, 2020, 9:18pm

For the moment, I thought that's it !!!
But unfortunately not so... Still the same...

ftp> passiv
Invalid command.

Thanks for thousand times. That indeed brings one step forward.
Still I am getting error "502 command not implemented" & "425 can't open data connection"

So, now tried with Ubuntu. And it went forward for flashing. But after several reboot, it seems device is dead. Its not starting, but I could still enter in bootloader. Did I just bricked my device ???

Do I see this correctly:

One time (which OS?) passive results in Invalid command
another time (Ubuntu) in Passive mode on.
?

Below when I was using ftp on windows machine

Below I run ftp on ubuntu (load it on windows via SD card)...

Meanwhile, made some progress. Now, I see "OpenWrt" wifi, and also able to connect it. BUT its not loading webpage of router. And via LAN, its not even getting IP address. I have flashed openwrt-lantiq-xway-avm_fritz7312-squashfs-sysupgrade.bin

Any idea how to move forward...

tmomas · January 22, 2020, 9:06pm

You have installed a snapshot image.

juppin · January 22, 2020, 9:20pm

Device has static 192.168.1.1 and does provide ip with DHCP.

JFTR, for others finding this thread: Windows' own command-line FTP is not capable of passive transfers, this failure is normal. There are some third-party clients that could do it, but it's generally easier to use a unixoid OS' FTP client.

Or using a python script like the one from Gluon:
https://fritz-tools.readthedocs.io/de/latest/index.html

AbDhops · January 23, 2020, 6:08pm

I was able to use this script. But couldnt understand from where to get gluon firmware....

Woww... It is really long journey than I thought. I am really thankful for all of your help. Now I am inside router trying to install Luci. However, it is not automatically connected to internet. I understand that this is because of firewall. I tried to do offline installation as mentioned here. But at link, I am not able to find the packages to download. Is the location changed. I am not networking guy to configure the network via CLI. So I am trying to get GUI installed. And then to move forward. Or if simple CLI commands would also help to make box able to use internet connected on input DSL line.

I also tried to install 19.07 release. And it did. But then after, it seems router is not booting and stays in bootloader. Any idea what is going wrong.

AbDhops · January 23, 2020, 9:12pm

FINALLY... I made through...
It seems install file is not working. But File @ Upgrade URL is getting flashed. Router is loading OperWRT and also could get to webpage... !!!

Thanks again to all for all the help !!!
