Porting Zyxel LTE5398-M904

sorry maybe a stupid question when and if the device will be switched to Openwrt:

Zyxel LTE5398-M904

I have this device with root access,
what should you know to port to Openwrt ?

what features do i lose with an openwrt install on this ?

thanks to all the developers.

When someone who owns it get their hands dirty, someone like you.

Question is, what you should know ...

You're the guy with the device ...

I'm sorry but my skills are not high enough to allow me to carry out the porting

since in this period some zyxel models are added to Openwrt, I was wondering if someone has already started doing it (a developer)

surely I don't have the adequate knowledge, I can still help you/help me if possible for a possible debug if instructed how do it

Thank you

Hoping to do something useful, I attach what I have been able to deduce about the router
