iPhone 6 won't turn on after water damage clear up

Hi ifixit family!

The iPhone 6 dropped in a water and won't turn on anymore. I checked and remove the capacitor C5202_RF (smoked/sorted). In this process, unfortunately, I broken the resistor R5201_RF. But after this this iPhone turn on (power supply shows 0A when tunr off)... I tested the basic functions (digitizer, LCD, sim card slot) and were OK.

Checking the board I saw some "oxidation" on LCD connector and near of baseband shield, so I removed the baseband shield and the other side shield and put the logic board in UltraSonic Cleaner whit 99.9% Isopropanol . After 2 cicles of 10 minutes I brushed the board (ESD safe brush).

For my surprise after the clear up process the board won't turn on. The power supply shows 0A and when I press power button the iPhone won't turn on and the power supply still 0A.

Suggestions for look up the board problem?

Thanks and sorry my bad english
