iPhone CPU Repair – Why Diagnosis Matters 【Tutorial】
Many beginners rush to reball or swap an iPhone CPU without a proper diagnosis – and end up killing the device. In this video, I share my SOP for confirming whether the CPU is truly the problem before touching it.
You’ll see the step-by-step verification process I follow, why CPU work is not an everyday job, and the risks of tampering with it.
If you skip the diagnosis, you risk sabotaging customer data and making the phone completely unrepairable.
Before you learn how to reball, make sure you understand when and why it’s needed.
These days, speed and going viral matter more to people than accuracy and doing the job right.
NOTE: You won’t see my hot air station temperature settings in this video. To follow my methods, you first need to learn how I calibrate my hot air station and compare it with yours. Sharing my settings alone wouldn’t help. The full calibration process is covered in my course.
