ITiPhone won’t turn on? iPhone stuck on Apple Logo? iPhone keeps restarting? iPhone boot loop? For repair technicians and repair shops, iPhone boot issues are one of the most commonly seen cases in their daily repair work. Facing these common but also tough issues, what you usually start with?
Yes, we are professional technicians and we know what to begin with. Your intuition may tell you that there might be something wrong with the boot circuit and you can start with the measurement of boot current. However, theoretically, do repair technicians really know how to handle the boot issue in a systematic way instead of simply trust their experience?
By systematic, below are some principles that repair technicians should all take into consideration when working on iPhone logic board repair.
Firstly, we should understand the work-flow of different iPhone circuits: how each circuit works; how different circuits cooperate and what they can achieve.
Secondly, we need to figure out which circuit might be responsible for the issue we are dealing with.
Lastly, we must master general troubleshooting process of each circuit.
Sounds complicated? Well, that’s why we bring you this iPhone Circuit Work-flow & Troubleshooting Course.

Now let’s get back to the most common boot issues mentioned at the very beginning. What do you know about iPhone boot circuit after handling so many boot issues? The boot circuit can be regarded as logic board trigger circuit. To have the phone turned on, working conditions like power supply, clock signal and reset signal are indispensable. What’s more, CPU has to get key components into power-on self-test process and get the bootstrap imported. Since there are so many components involved in the process, reasons for won’t turn on of the phone can also be various. ——————How iPhone X Boot Circuit Works
