@refectio Hi, i have a similar problem with an iphone 6. I have a question for you. What do you mean by “check c1402 and l1401” ? I have 4.38v on one side of that coil and 3.88 on the other side. Please help me because I don’t know what do try anymore. Already replaced tigris, tristar, checked all the voltages nearby and they all seem fine.
