It’s really odd to me how few ROMs support this phone. I think it’s because there’s such a small user-base and at the same time the official ROM is so close to AOSP (and AOSP has gotten pretty good) that people don’t bother switching. I own one, and am happy to do anything to help, I just don’t know what’s needed (I’ve actually gotten pretty deep into AOSP before, I just never figured out how to port a ROM myself). It would be amazing if I could schedule time with someone and work on it together.
