Perfix is a professional repair tool targeting all Apple devices issues, either caused by the system or the software. If the issues are not caused by the device hardware, we normally have 95% success rate based on our previous statistic.
Perfix has two different repair methods, Standard and Advanced repair. You won’t lose any data at Standard Repair mode. However, the Advanced Repair will reset your iPhone (same as a factory reset).
Standard Repair works perfectly and can fix ~90% of iOS issues. We highly recommend that you first try Standard Repair regardless of the type of the issues. If it is not working, you may want to try Advanced Repair.
