Is it worth adapting openwrt to Vodafone Power Station SHG3000

Greetings!

Recently I bought Vodafone Power Station on a flea markt for 2 euros. I really liked its characteristics - powerful SoC, 0.5G of RAM... But native vodafone firmware makes it impossible to use the router for something except vodafone services. There is no even a bridge mode.

I checked support of this model by OpenWRT. Currently it is not supported. But it seems that SoC Broadcom BCM63136 is supported (from wiki: But a new Broadcom ARM bcm63xx target is required for Openwrt support.). OpenWrt wiki says that wifi chip BCM4360 is probably not supported, but in my device there is BCM43602, that is supported by brcmfmac.

I work in data analytics, but like to work with hardware. So, I know something about the topic. How difficult is it for an amateur like me to extend support of OpenWrt to the vodafone power station?

wifi will be crippled, at best, even when/if supported https://openwrt.org/meta/infobox/broadcom_wifi

So, is it better to try to adapt ddwrt?

not sure how that would work, it's not like they're going to give you those BCM NDA drivers...

I checked a list of ddwrt supported devices - 6 of them have BCM43602, 8 have BCM4366 and about 50 have BCM4360. So somehow the developers have got the drivers for those devices...

You're missing the point ...

I'm not saying it isn't doable, I'm saying you can't get it to work 100% yourself, since they won't
give you the wifi drivers. A certain part will have to be done by them, unless you can extract the
missing parts from some existing firmware...

Oh, I thought that ddwrt like openwrt is developed by a community. But it is developed by a company...

Anyway, thanks a lot for the answers!
