Hello Guys,
I bought one ZBT-Z8109AX, and I would like to install the latest Openwrt firmware on this board. As I see well, there is no downloadable firmware for this unit. I tried with the Z8102AX, but its not works (because of the different hardware). I have serial cable, etc for the install. Any suggestion is very welcome.
Thank you!
The device is not currently supported.
Some unfinished effort here:
Thank you for your answer, its a bad news. As I see well now its supported by Openmptcp, which is openwrt based...
No sign of support in that thread.
Are you interested to do the gruntwork?
Good idea... I will try 
Get bootlog
Get dtb and decompile to dts
Based on that try to tftpboot openwrt kernel for similar device. Via u-boot obviously.
