First of all thank you for your quick reply. I have changed the logic board because it was not turning on and found out that Lots of pads were cut off from the ways. So instead of making a way for all them changed the housing. I will check for the radio system but new on 11 so where can I look at directly?
By the way I have checked the caps resistors around baseband and bb pmu and also pads on diode mode. Everything was perfect. So I was just going to start to measure the top layer but got your reply.
Will check the radio too if you can light me up that where I can start with.
Thank you
Emre
