How to fix iPhone 6S can not start failure
We received an iphone 6S that could not be started. First, use the iPhone Opener to remove the power box and power it to 100mA to check if it can be connected. We connect it to the computer and display the DFU mode. Unlimited DFU cannot exit. In response to this situation, we can only brush the machine for error.
Brushing with Aisi and iTunes respectively, both will stick on the progress bar here for a long time reporting -1. The progress bar does not go, you can roughly judge the probability of the CPU failure, and then, we decided to test the hard disk. First, measuring the power supply, the vertical capacitance of the left side on the hard disk can be measured to 0.9V, 1.8V, 3.0V, and the phone power supply is normal.
Removing the hard disk to test, first hit the resistance value, and the resistance value is normal. Test the hard disk on the test stand, this 6S original hard disk is damaged, can't read the data and can only be replaced.
First, query the serial number through IMEI, the professional serial number activation staff can find the Bluetooth and WiFi address (referred to as three codes). After the 11-system mobile phone is replaced, the hard disk must be written to the original machine for three codes to activate.
Before writing the code, write the underlying data of the corresponding model, you need to use JC PCIE IPhone 8 8P X NAND Test Fixture. If there is a problem with the underlying data, there will be various strange problems. This is the underlying error phenomenon. After taking the photo, the mobile phone screen is reversed, re-write the underlying data to solve the problem.
There are also some assembly hard disks, 4.7-inch mobile hard disks on the 5.5-inch machine, subtitles display is not normal, which is also caused by in-correct underlying data. This 6S boot DFU brush machine progess did not go, the problem is solved after replacing the hard disk.
