Removing the Lock Screen Passcode
First, open Apple Configurator on the MacBook that the affected iPad was supervised to and choose 'Supervise' from the top center of the Apple Configurator window. Once 'Supervise' is chosen the double iPad icon above the word supervise will become blue.
As previously discussed in part 1 of this 4 part iOS Passcode lock series, the most common location an iOS passcode lock is encountered is on the lock screen. You have probably run into this passcode when you or a student attempted to "slide to unlock" an iPad and are greeted with a number panel instead of the home screen.
Fortunately, if the affected iPad was supervised using Apple Configurator prior to this iOS passcode lock incident then the removal of the passcode is quite easy to accomplish.
In the far right column, you will see a status that the "devices are being updated" and a list of the connected iPads.
Once this process is complete, the original configuration and settings will be applied to the affected iPad. Return to the iPad and 'slide to unlock' the device. The iOS passcode lock box will briefly appear and then you will be taken directly to the home screen. Mission accomplished!
At the bottom center of the Apple Configurator window, click the 'Refresh' button.
Next, connect only the affected iPad to the MacBook using a single iOS device cable. If you do not have a single iOS device cable it is okay to utilize one of the slots and cables in Bretford PowerSync cart.
In the Apple Configurator window, choose 'USB Connected' in the left column and then click the words 'All iPads' located in the middle column.
