I'm kinda new there, even if I had heard of OpenWRT for a while. I recently bought an Archer C9 and I was interested in flashing OpenWRT on it. However I found it it wasn't supported yet (listed in unknown status). It seems like the Broadcom platform may prevent it for being fully OpenWRT-ready, right ?
I already saw this topic, I tried looking at the doc for a long time but honestly this is far beyond my poor programming skills...I could maybe learn it with time but I currently don't have much time and it's not likely to improve in the next 6 months.
So I did what I could do : opening my Archer C9 and taking pictures of things inside. I couldn't go through metallic parts under the heatsink but I documented everything I could document. Some components have something written on them but it's too small to see that in pictures : I numbered them on the pictures and I wrote back those writings under those.

I didn't know where to drop this info so I posted here. I hope this helps.
