I have an iPhone 7 which came to me looking like it was thrown against a brick wall but the board looked good. Power is coming in fine, but amperage is constantly rising to 480 milliamps and dropping, over and over. With freeze spray, I found that it's heating REALLY rapidly under the CPU where pins c65/c66/d66 are (pp1v8_sdram and pp1v1_sdram). Can someone throw me a bone? I've checked for shorts at every point that these pins are related to. Can someone help me get on track?
