Always power down your device before attempting any repair.

This is the only stressful part of the repair but is surprisingly easier than it seems.

You need to remove the existing cracked bezel. Use a hairdryer to carefully loosen the adhesive.

NOTE: The adhesive is a 4mm strip of double-sided tape and it is only on the top side of the bezel. Be extra careful if you are using a hairdryer or heatgun.

You may not need to use heat to loosen the adhesive, I simply used tweezers to pick off bits of glass and was able to slowly take one side off. Then simply running my nail down the other half, the whole bezel came off in one go.
