Have you tied reballing or reflowing the PMIC that handles the charging circuit and check all the components around that area ? Also, have you tired another battery ?

Yes, you are right.
But for the purpose (charging and middle to bottom side of the board) are identical up to components. If the C335 arrives the 3.8V, the issue should be the U501 (power manager), this model hasn't a USB/Charger IC alone. Reflow it or replace by other one.

My problem is no power on, I will change U501 because some parts of main board no have voltage, and when I put the charger, battery connector is 0v, so I will replace it.

if you have power supply, what displays at press power time?
