Based on our training experience in the past years, many experienced repair technicians are not so good at theory. They know how to fix some common issues like iPhone 6 plus touch issue, iPhone 7 audio issue. But they don't know why these happened, how to troubleshooting, especially for new models or new happened issues, they are mainly repairing by experience.
If you are like them, we suggest you to choose our work flow & troubleshooting course and repair case course in these two courses you will learn how different circuit works, how to troubleshooting for different circuits of an iPhone and many real cases during our repair experience.
We also supply a more cost-effective course bundle For Technicians Course Bundle.
