i have here an iPhone 6 it work ok still wifi and bluetooth and sometimes Network Problem i have, wifi was greyed out.
After this i take out the logicboard and reflow the wifi Chip Around 250C 10-20 Seconds, cool it down Then install the Board. After Switch on no Funktion at all, i only get heating around the CPU, what can be go wrong and what I damaged with the reflow. Is it the Power IC, because seems to be I get a short.
Someone any idea about who can give me a hint.
