Bringing a Dead iPhone 14 Back to Life (NAND Surgery)

In this video: I perform a complex logic board repair and data recovery on a sun-damaged iPhone 14. This device was misdiagnosed by another shop as having a fatal "CPU issue", but by stepping through component-level diagnostics, we trace the actual failure to a dead NAND chip. Watch the full process of diagnosing a low current loop, splitting the sandwich board, reballing the BGA, bypassing iTunes Error 2009 and successfully resurrecting the iPhone 14 👇 NEED YOUR DEVICE FIXED OR DATA RECOVERED? 👇 I run Repairtech Rx, a professional microsoldering and motherboard repair shop based in Greater Sudbury, Ontario.
