Pool water damage device goes into bootloop

Hi,

     hope u r all doing great and safe.

I have a water damaged op7p and i am hoping to fix it but i do not have a clue what parts i will need to change so i can order from u. Below are some details i hope that could help u identify based on ur knowledge and appreciate if u would.

I had pool water gotten into my op7pro and it now doesnt boot but just hang after the spinning animation and wont go pass it, it hung there while spinning logo and keep rebooting and repeating until i have to power it off manually by holding power and vol button to go into boot loader or recovery and power off from there.

I was able to boot into twrp, decrypt and perform usual operation and even access my data until i wipe it and used msm tool.

Now while i can still go into stock recovery and bootloader but i can't even flash any recovery or perform any other operation when i cant boot up and go into dev mode to enable oem unlocking. Cant even unlock boot loader or switch partition neither flashing any stock roms etc.

I had done what i could drying it in rice and bought to shop to try for repair but to no vail. But theres jus this part in me telling me it could be just a simple part to be replace like a flex cable or something.

Any help is greatly appreciated and i wish everyone safe from the convid 19.
