I just got a new Galaxy S9 to replace my 3-year-old Galaxy S6 and I will be giving it to my mother so I did a Factory Reset to my Galaxy S6. To my surprise, doing a factory reset didn't actually delete everything from the phone so I went into recovery mode and did a "Wipe data/factory reset" from there.
After restarting the phone and connecting to a WiFi network I'm asked to enter my Samsung Account, which I did, but I can't get past this screen! When I click on the "Sign In" button this is what happens:
The dialogs disappear and nothing happens. If I put a wrong password it tells me the password is wrong but when entering the correct one I can't get past this. I tried doing a factory reset again, unlocking the device from my Samsung account (which fails because it says remote access is not enabled or something like that) and even removing the device from my Samsung account. I also tried multiple methods that you can find online to bypass this but none of them work on Android 7 (Nougat).
I don't know what else to do, my device is just unusable now.
