[OpenWrt-Devel] [RFC] Support for ZyXEL LTE3301-Plus / Image format known?

[Andre Valentin]

Hi!

I have written support for the LTE3301-Plus device for OpenWRT. But my main problem is that
Zyxel only gave me an binary imagebuilder. If anybody is interested I can provide the needed
OpenWRT patch and the binary. Perhaps someone is able to decompile it and back or even
better, the format is known :-)

_SPECS:_
4 Cores (HT)
MT7621
128MB Flash, ~60MB usable
256MB RAM
4x switched ethernet ports
1x MT7615E Wifi
1x USB3
1x Quectel LTE modem
