At first I wanted to delete cached data and I found it very big about 4.14 GB,,I deleted it,,after that the phone didn't open any program ,,I restarted it,,it closed and didn't open back,I tried to open it but no response,,I put it in the charger,,the led lamp gets red (not blinked) and no response to power button also,,do you have a solution?

How did you deleted that file? was your phone rooted?

No it wasn't rooted

I deleted it by clicking on cached data then choosing ok

That shouldn't affect your phone, connect the phone to a wall charger > press and hold power & volume up for 10 seconds > let it charge for 2-3 hours
