The customer said that he did not know what the reason was. The mobile phone has been restarted indefinitely and can enter the DFU mode. However, when the flashing machine fails to enter the recovery mode from the DFU mode, and then the mobile phone is connected to the computer for 5-10 minutes, it automatically enters the recovery mode.
After we received the 6S that could not be started, we disassembled the power with iphone engraving tool and turned on the power to 100mA. First of all, check if you can connect and read the DFU mode after connecting to the computer. Wireless DFU can not exit, we can only brush the machine to view the error.
Refresh Aisi and iTunes respectively. If you stuck on the progress bar for a long time, it is very likely that the error is -1. If the progress bar does not enter, you can roughly determine the probability of a CPU failure. Now we need to see if there is a problem with the hard drive. First, use DC power supply for iphone repair, the hard disk on the left side of the capacitor can be tested to 0.9V, 1.8V, 3.0V, the result is normal power.
Before writing the code, first write the basic data of the corresponding model. If there is any problem with the underlying data, there will be some strange problems, which are potential errors. So you can use the JC PCIE IPhone 8 8P X NAND Test Fixture for reading and writing. After watching the camera, the screen is reversed. Rewrite the underlying data to solve the problem
There are still some hard drives on the 5.5-inch machine, 4.7-inch mobile hard drives, and incorrect underlying data may also help display normal subtitles. This 6S boot DFU brush machine does not work, we solved the problem successfully after replacing the hard disk.

Delete the hard drive to be tested. First, it is normal to reach the resistance value. Test the hard disk using the iphone test fixture . This 6S original hard disk is damaged, the data can only be read but can only be replaced.
First, the serial number is queried by IMEI. Professionals with a BT WF address can find Bluetooth and WiFi addresses (called three codes). After replacing the mobile phone, the mobile phone after winning 11 must be written into the original three codes to be activated after the hard disk is replaced.
