Could you please try connecting your phone to a computer over USB? I am trying to revert it back to the last firmware, but my computer just charges the phone and wont recognize the phone as a USB device anymore either...
Where did you get the update from? Why am I not seeing that update?
You have a G930F which is a European Galaxy S7 using the Exynos 8890 processor.
I have a G930T which is a US T-Mobile Galaxy S7 using the Snapdragon 820 processor.
I'm having the same exact problem, and it didn't dawn on me until I read your post that my fast charging stopped working once I did the firmware update.
My husband has the same exact phone (we got them at the same exact time) and he's been putting off the update and his fast charging still works. Now I'm regretting updating my phone. Because my phone is constantly on life support (connected to the wall charger or my power bank). I truly hope this is something Samsung can resolve with a patch.
@PengyMermaid Is yours a European Galaxy S7 too? i.e. G930F
