I got an old s7. Looking through the settings it says:
Model Number: SM-G930FD
Build Number MMB29K.G930FXXU1BPIF
I am trying to find a compatible firmware to manually install, since when I told the phone to search for updates it does not find anything. The device has Android 6.0.1 with September 2016 security update which looks very insecure to use.
I am trying to find a compatible update, preferably based on android 8 and released during the last two months. However I am not sure about what to use.
Another strange thing is that when I try to find the existing firmware on the device I cannot find it when searching for SM-G930FD. However I do find this entry for SM-G930F with PDA G930FXXU1BPIF. Also if I enter download mode the phone shows:
PRODUCT NAME: SM-G930F
I am not sure what to make of this. Is the phone a G930F or a G930FD? And what should match when I try to find an official firmware that should match this phone's hardware?
