Having the same problem with nougat :(
Let's really hope that someday it's going to be fixed, it's really a great and useful module!
I just wanted to give my suggestion for a platform I use often.
I don't have the phone, I was just thinking of buying it as a travel phone because of the large battery but the lack of custom rom stopped me.
I may participate with the foundin...
At the end I've found the last version for tilapia here: downloadandroidrom.com/file/Nexus7/3groms/C-ROM
So far it works perfectly on my Nexus 7 3G.
I thought that it might be useful for someone :)
thank you so much for taking the time to write a tutorial!
I'm going to try it on my gpd pocket as soon as possible that at the moment is running this build https://kmyers.me/blog/computers/public-preview-chromiumos-for-the-gpd-pocket-1/ .
guys, we could use a platform like www.bountysource.com. It would be great to have lineage os ported to this nice phone (which just lack a cleaner os)
