ADB Android Device Unauthorized (No Revoke USB Debugging Authorizations) Nougat

I suddenly have trouble using ADB to connect to one of my phone running Nougat. Like How to Fix ADB Unauthorized Error's author, I do not have Revoke USB Debugging Authorizations option anywhere. Unlike the author, I still see an authorized device in my adb even after I boot into the recovery.

I also followed Missing USB revocation on Android with Nethunter with zero luck.

I tried to connect the same mobile device (Samsung S6) to another mac (never connected before) and encountered the identical issue...

  1. Android Device: Connect device via USB with 'file transfer' connection
  2. PC: execute 'adb kill-server' followed by 'adb start-server'

You should be prompted for debug authorization in the android device following this process. If not please revoke all debug authorizations in android settings and repeat.
