During the use of iPhone, restart problems often occur. Today, Phonefix will learn with you the troubleshooting and repair guide for iPhone restart fault data.
To solve the iPhone restart problem, we must first find the specific data. We need to click "Settings - General - Privacy - Analysis -Analysis Data" on the iPhone, and then find the file starting with "panic Full" among the many files. Find the restart file of the corresponding time, check all the data after PanicString in the file, and then conduct in-depth analysis of these data.
Different data point to different fault directions. For example, "Ememory", "Menorystaus_jetsam_thread", "nvme" and other data point to the iPhone Hard Disk or hard disk related circuits. Once they appear in the data, it is necessary to focus on checking whether there is a problem with the hard disk or its related circuits.
I2c series data corresponds to different chips or accessories corresponding to the sockets according to different iPhone models, and checks the relevant hardware. In I2c1 (A8-A12 series), I2c0 (A8-A12 series), I2c2 (A8-A12 series) iPhone, it and J4300 check tail plug J6400 contain MIC all have data bus.
I2c1, I2c0, 2c2, I2c3, I2c4 and I2c5 each series has its specific direction. Maintenance personnel can accurately check the corresponding cable, chip and accessories according to the information to determine whether there is a fault.
For "AOP PANIC" data, it may involve distance sensing, rear noise reduction MIC, iPhone 7P Power Cable and other aspects, and even whether the fingerprint is damaged. If the recording restarts, you have to consider whether there is a problem with the screen. "CPU solder joint failure" may be prompted by data such as "AOP DATA ABORT", "Attemping to forcibly halt CPU..cpu0 fail to halt with error" ; "battery problem" can be judged from data such as "WDT timeout", "Apple PPM", and "Apple PMGR".
"AppleBCMWLAN" is related to the WiFi and Bluetooth functions we often use; "baseband" represents the Baseband Part. If the baseband fails, the communication function of the mobile phone may be damaged.

When repairing iPhone restart failure, there is also a universal rule: first rule out the problem of external accessories. Because in many cases, the restart failure may be just a minor problem with the external accessories, such as damaged Tail Plug and poor contact of the cable. Only after the external accessories are checked correctly, check the hard disk.
