• I own the device and am willing to test the installer on it.

Additional context

It's the S5 Mini with Snapdragon 400 processor. The device that I have access has never been modified, and it's running the stock version of android, baseband G800HXXU1CPI1, and compilation MMB29M.G800HXXU1CPJ6
Sadly, the fingerprint scanner is not working even under official firmware, so I can't test that. Maybe I'll try to fiddle with it after using custom ROMs.
