Chosen Solution
Hi all. Got a iPhone 7 that’s giving me some trouble. I wanted to get some input before diving under the scope. When I first checked the device, it was boot looping when powered on, but also when charger was plugged in. I replaced the battery & screen (was cracked), and all was good. It functioned very well. I turned the phone off for a few days and left it alone. Today, I went to turn on the device and it wouldn’t turn on. So plugged it in and it turned on, functioning well with the charger. Battery showed 100% and charging sign. When I unplugged it, it goes black and starts boot looping. I then unplugged the battery and added the charger, showed Apple logo and still boot looped. Are we thinking board-related issue (Tristar)? Things I Checked: New screen - still performs the sameBattery - Showing 2.7v (strange since it’s brand new)DC Power - Shows no short & boot loops
First I would put it under your scope and check the battery FPC and R2201 which is beside it, also a faulty charging dock can also create these problems. If all these check out to be good I would move onto Tristar than Tigras.
