Pcb is not working after the latest android 5.1.1 update?

[Nikhils246]

Nexus 5 is not switching on and service center is saying pcb is not working. This happened just 2-3 days after the latest android update. The phone is stuck in initial android animation screen. No buttons are working.

Welcome to Android Central! Are you saying you brought it to a service center, and they think the motherboard is faulty? Can you boot into Recovery Mode? http://forums.androidcentral.com/nexus-5-rooting-roms-hacks/352008-guide-nexus-5-recovery.html
