This would be something else in addition to an emergency unbrick.

The ability to press a button that sends a text or a notification to 1-5 friends asking for them to allow you to unbrick your phone.

This feature would also allow you to put a description why you are requesting an unbrick that they can read.

Once they click the link in the text they can either approve or deny (with a reply) and I think the trick would be to make it so when you setup the friends who get notified you can choose whether you need approval from ALL 3 friends before you can unbrick or just approval from one of them.
