5. Known problems on Nothing and CMF

6. Turn it all back off

  1. First, in each app that used Shizuku, undo what it changed, while Shizuku still runs. Some changes an app makes through Shizuku stay after Shizuku stops. Firewall and Fileglow have their own steps.

  2. In Shizuku, switch off every app in the list of authorized apps.

  3. Stop Shizuku with its stop option, or restart the phone.

  4. Open Developer options, then Wireless debugging, then Paired devices, tap the shizuku entry, then Forget.

  5. In Developer options, tap Revoke USB debugging authorizations. This removes every paired computer and device.

  6. Turn off Disable adb authorization timeout if you turned it on, and set Default USB configuration back to File transfer if you want.

  7. Turn off Wireless debugging, then USB debugging.

  8. Turn off the switch at the top of Developer options: Settings, then System, then Developer options.

  9. Set Shizuku's battery setting back to the default (Optimized) if you like.

  10. Uninstall Shizuku the normal way if you don't need it any more.
