'How To Fix iPhone 8 Stuck on Apple Logo' --post by REWA Technology
'iPhone 8 stuck on Apple logo with an unresponsive home button? Why and how? Different from previous versions, there is a built-in hardware detection during booting process for iPhone 8. Once touch ID gets malfunctioned, the phone will hang on Apple logo during startup and therefore won't turn on. If you are troubled with the same problem that iPhone 8 can not be activated, check this video for the solution!'

To fix Iphone 8 Stuck on Apple logo, the repair steps as following:



Related Reference Video Source Click Here

Step1:
Power on, Apple logo displays normally. Yet the phone gets stuck on Apple logo and can’t boot up completely.

Step 2:
Connect the phone to computer and restore via iTunes. Then insert the SIM card and activate the phone.

Step 3:
The Home Button gets unresponsive with returning function and the phone fails to activate completely.

Step 4:
Disassemble the phone and disconnect the battery. Then remove the display assembly.

Step 5:
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 sets of voltage.



Step 6:
Check whether the 3D flex cable of the display assembly is damaged or not. The 3D flex cable is in normal status.

Step 7:
Detach the Home Button and check whether the home button flex cable is damaged or not. The home button flex cable is in normal status.



Step 8:
Since Home Button is connected to the logic board with flex cable on the display assembly, to further confirm the fault point, replace with a new display assembly. Get the Home Button mounted on the new display assembly. Buckle the new display assembly to the logic board. Then power on.

Step 9:
The phone still gets stuck on Apple logo and can’t boot up completely.

Step 10:
Remove the display assembly. Switch to diode mode and measure the resistance between J5800 pins and grounding. Normal resistance value. There are obvious repairing marks on J5800 under the microscope. So we can have the connector J5800 replaced for a try.



Step 11:
Take out the logic board and attach it to PCB Holder. Stick connectors next to J5800 with high-temperature adhesive tape.

Step 12:
Apply some BGA paste flux to the bonding pad and take down J5800 with Hot Air Gun at 320℃.



Step 13:
Then Solder tins with Soldering Iron. Which is helpful to the subsequent soldering process. Clean with PCB Cleaner afterward.

Step14:
Apply some BGA paste flux to the bonding pad. Align the new connector to the right place. Then solder the new connector with Hot Air Gun at 320℃.



Step 15:
Wait for the logic board to cool for 5 minutes and then clean with PCB Cleaner. Check again to confirm soldering status.

Step 16:
Get the logic board assembled and connect the battery. Buckle the display assembly and power on. The phone gets access to the activating interface normally.

To fix your iPhone 8 stuck on Apple logo problem, you can try the following solutions:
1. Force restart your device. It's the simplest method to solve most iOS problem directly.
2. Put your device into recovery mode. However, all the files on your iPhone will be removed after using this method.
3. Restore your iPhone into DFU mode. A DFU restore actually reloads the firmware (controls the hardware of your device) thoroughly but not only the software.
4. Use a professional third-party software such as TunesKit iOS System Recovery to fix iPhone stuck on Apple logo without data loss. It's easy to operate and the sucess rate is super high. You can have a try.

You are suggested to know the causes of iPhone stuck on Apple logo, such as restore, update, jailbreak, and so on. Then try solutions, like restore in recovery mode, DFU mode, let iPhone system fix on Win, restore with DFU mode and more. You can also ask Apple Support for help.
