Hello everyone.. I recently got a Note Air 2 from a thrift store but unfortunately it is pin code locked. I tried factory resetting it couple of ways to no avail. If anyone could help me, I would really appreciate it. I tried the below two methods.
Method 1 - Pressed power button for 10s and then pressed the power button again 5 times and get the below screen with 'No Command' and not the menu with option to factory reset.

Method 2 - After the above did not work, I tried with adb and fastboot. I don't think USB debugging is enabled, but still thought will try this way. When I try to list devices using 'adb devices' command, I get like below 'unauthorized'.
