How to replace a phone motherboard?
my phone is not working and display is broken i replaced the whole display but still not working what should i do
You can replace the motherboard but perhaps try and find out what's wrong first.
Here's the troubleshooting section from the service manual.
Go to p.6 to view the Power On flowchart what to check first.
You will need to have a DMM (digital multimeter) and know how to use it to try and fix the problem, otherwise replacing the motherboard may be the only other way.
