A2338 new M1 MacBook Pro problem Logic Board related after liquid spill 820-02020

Hello, I've got this Mac from a friend who spilled wine on it. MacBook boot right onto options screen and does not boot the os. Reinstalling Mac Os does not help, it does conclude but same option screen after install. If I try to select the startup disk it gives me "error SDErrorDomain 108" and it does not go forward. I cannot manage to enter DFU for whatever reason. I opened and found corrosion nearby trackpad socket and other components who I cannot identify as I don't have schematics, you can see the photos above. After try to clean with IPA I noticed that i've lost a pin on the trackpad connector board side, so trackpad now is not working after cleaning (my foult, maybe due to corrosion) but before screen, speakers, keyboard and trackpad was all working, except id does not boot in to os.
Any advice of what to check would be really appreciated!

PS I took photos before and after cleaning. Nothing changed, still no OS boot.

UPDATE:

Now I'm able to boot MacOs.
Options boot loop was caused by faulty TouchID button, removing cleaning and putting back solve it. Error SDErrorDomain 108 setting up startup disk was override by wiping interl SSD and formatting to exFAT, then mac os journaled and again APFS before reinstalling MacOS again. Really dont know if it's just random behavour or lucky.
Anyway, it's seems all to be working, except for trackpad (waiting for new cable and logic board FPC connector) internal Fan (no fan spin) and TouchID (won't accept finger print, it does work only as on/off button).

Any suggest?

2’ND UDPATE:

After disassembly fan I noticed it was literally “glued” and sticky inside.. Wine �� does not meant to be drinked by laptops.. I cleaned and put in ultrasonic bath. Same for the touchID. Now both are fully working, also finger print.
Only trackpad remains, until I got ribbon cable and logic board connector FPC ( it seems that A2338 is common to A1706, so I ordered this one).
Hope that will successfully replace and work.
Last thing is the halo left on the backlight of LCD where liquid goes inside. So I will try to disassemble LCD and take of the foils inside it. I already replace a couple, but all of them have already broken LCD panel so the goal is not damage it while removing. If this is going to happen I need to replace both LCD panel and backlight foils.

Hey slimmy182,

Thanks a lot buddy, the steps below helped me to get through a chronic issue which Apple & their next level support were struggling for last few weeks!

You are a rockstar!
