Before ordering a new Cpu look [https://www.youtube.com/watch?v=g4PSx3mxdZ4|here] to see what a Cpu replacement involves. "First of all, the CPU is serial number locked with the Baseband IC, the NAND and the BB EEPROM. So the only way to migrate a CPU is to migrate all of those IC's (and the Home Button)." as @refectio said in this [post|465892] Hope you are a well-experienced technician to do this by yourself.
