How to repair iPhone 8 stuck on Apple logo

图片
We got an iPhone 8 from a customer and his iPhone 8 card was on the White Apple and could not be opened. What caused it? How to fix this fault? Open the iPhone and the Apple logo displays normally. However, the phone card is on the Apple logo and cannot be fully activated. Connect your phone to your computer and recover from iTunes. Then insert the SIM card and activate your phone. The Home Button gets unresponsive with returning function and the phone fails to activate completely. Disassemble the phone with iPhone opening tool kit(VC862) and disconnect the battery. Then remove the display assembly. Use digital multimeter to measure the power supply voltage of Home Button. The measured voltage value is 3.3V, 1.8V and 2.75V. Normal voltage value for the three are normal. Then, remove the Home button and check if the iPhone fingerprint flex cable is damaged, in fact it is in a normal state. To further confirm the fault point, we replace with a new display assembly. Get the...

How to fix iPhone 6P unlimited reboot?

We received an iPhone 6 Plus and described the failure of the iPhone 6 Plus to restart indefinitely after the appearance of the white Apple logo. We speculate that the IC that may cause the iPhone White Apple to fail to restart is the CPU, iPhone Nand flash , iPhone logic eerpom IC, iPhone baseband and so on. What should we do now? First we need to check the working status of these chips. Measuring the grounding resistance value and power supply for the iPhone CPU, both measured value are normal. Next measuring the working condition of the iPhone Nand flash, it's also normal. When measured the iPhone eeprom IC, we found the bus (AP_TO_EEPROM_I2C) connected to the iPhone logic eeprom IC and the iPhone CPU has some problem, the grounding resistance value for one of clock bus is more than 600, but the normal data should be around 400, seems there is a disconnection or the pin of the iPhone CPU is empty-welded. Because there are only 1 bus has the problem, so we choose to dig ...
