Who I have the same questioned this topic

Hello,

iPhone 6 died completely & unexpectedly. Verizon sent replacement phone, now in-hand. Supposed to return old phone, and all instructions say to wipe data first. How? Phone is dead & shows no signs of life, for me or store employees. Can't turn on or power or anything related to life.

Please advise, have to send phone back within 5 days.
