I not understand how you people do that. If i reheat the customer come always again after one or two weeks. 18 of 20 people come always back with the same error. I not reheating it anymore.

My iphone 5c keeps searching even before i made a reflow on that chip.
I was comparing its board with another one that i have here and i found out that are 3 spaces where on the other board has 3 capacitors ( baseband ic)
Can those 3 capacitors be the cause of searching problem? or i should try other methods like change ic , dfu mode etc
I have imei but blank modem firmware
