I have read a lot of posts about this but still get nowhere. I reset
phone to its base android 8.0 and have it rooted etc.
It has a 4 GB sd card that was just formatted on the phone.
What happens next (and how)?
We don't actively support Fedora on phones, there's a lot of
complexity involved. That being said there are some people that have
put Fedora on various phones.
In Fedora we only support booting aarch64, which the S7 is, with UEFI
so some of the process will be getting a kernel booting like that,
you'll likely need a custom kernel because the requirements between
Fedora and Android for kernels are a little different.
Also which version of the S7 because there's at least one with some
Samsung EXYNOS processor and one that has a Qualcomm processor, I
suspect you'll have better luck with the later
Basically the Fedora ARM people aren't focused on Phones as they're
problematic and a constant moving target and we really just don't have
than many resources so we're focused on more Fedora things like
servers/laptops/desktops/dev boards/IoT etc.
