iPhone 12 Data Recovery: CPU Separation on a Refurbished Board

A broken iPhone 12: no power, no charging, no response. What looked like a simple board failure turned out to be a refurbished logic board with a poorly reapplied CPU. Here's the full diagnostic and recovery process. 🔧 Need professional data recovery?
