Alcatel 1s 2019 new battery + charging port, dont work

Hello everyone.

A friend of mine asked me to fix his phone. It is a Alcatel 1s 2019. He said that the battery didnt work.

I buy him a new one and installed myself but still now working. I ordered a charging port from China, and 2 months later I receveid. Yesterday I put the new charging port and the battery but the phone still now working. Probably its from ther motherboard but I want to be sure if there isnt any solution. Can someone give me some advice?

Thanks guys.
