Hi
One of the customer brought an iphone 4s. The phone stills "searching", after battery replacement. The date is value, so unfortunately, I think, its an other problem this. I checked the logic board with microscope, and I saw this broken chip.
what is this 6 pins chip? Tomorow I will resolder this.
I marked with yellow.
Thanks.
Tibor
