Samsung A40 Sea Salt Water Damaged. ((Photos and Video Included!))

Hello, I have a samsung a40 that fell in salt water at like December of 2023. I tried to fix it in mid 2024 but I got no signs of life. Today, which I have more tools than then, I tried to fix it again. I took off the shields off the chips and cleaned everything with 99 percent alcohol and an ultrasonic cleaner with distilled water. After replacing battery and charge port and sub-main cable, the phone draws 0.00 amps and a high pitched noise comes off the mainboard. No vibrating and no speaker, and no screen sign.I have a lot of important photos on there that I would like to save. Does anyone know if this phone is saveable?? And if it is, how should I proceed??Please answer it is very important!! Thank you.Here are some photos of the main board and a video of the high pitched sound when charging:
