Asus Zenfone 5 phone not turning on after factory reset I received an error message on my phone 


  Unfortunately, the process.android.process.acore has stopped.


So I have tried to factory reset it. Now it doesn't turn on at all. It just shows the Intel Inside logo. I am clueless about what to do. Any help?
You have two options, either you can send it to the service center of ASUS as it is still in warranty period, or you can flash the stock rom. But you may have some warranty issues in future if you flash it by your own.
