iPhone 4S not turning on anymore
My iPhone 4S is not turning on anymore, even when plugged into a wall charger.
It is not showing the apple logo and the battery is not even getting warm.
After using another logicboard it booted just fine without any problems.
What do you guys think is the problem with the logicboard?
Thanks in advance

What is the voltage on your battery connector when you plug it in? Check if there is continuity between the - and + on your battery connector.

My connector was giving me 0 volts, so I looked at the schematics and after a while noticed the wifi chip had a short.
After replacing thhe chip my iPhone was starting up, but R49_RF and C13_RF are missing, and my U5 was getting veeeery hot, with the batteryconnector reading 4,05volts.
But after 1 day it would not become hot anymore and booted normally, but now the wifi is greyed out.
Has it something to do with R49_RF and C13_RF missing?
