Thanks for reaching out to us in order to find out about gaining solution(s) to restore your Samsung Galaxy Tab S8+ 5G into full working optimum condition. I feel you that you've cared so much for your device, trying out several attempts and methods to have it working again but to no avail. If my device has similar exposure at the rooftop and got accidentally soaked due to heavy downpour, I will be more bothered too.
First, you need to stop whatever you doing on your Tab S8+ to avoid electric shock and further damages to it. I highly recommend bringing it to the nearest Samsung Authorized Service Center in your area. So our Team of Samsung experts consist of engineers and technician can assess and diagnose your device. Rest assured that any result or findings will be relayed to you prior repair or restoration.
or book an appointment with the Samsung Members app as follows:

Hi there, N0N0K! So sorry to hear about what happened. I'd suggest you visit a nearby service center as soon as you can to get your Galaxy Tab S8+ diagnosed and repaired. You may book your appointment directly from your Samsung Members app, right under the Support tab, or you may dial #GALAXY 😊 Hope you get this fixed soon so you can fully enjoy your tab again!
Copy that. Unfortunately, there's not much we can do to diagnose your issue online. Hope you find the time soon!
Alternatively - you can try dunking your tablet in uncooked rice to help absorb some of the moisture that might still be causing your device issues. I can't guarantee that this will help (or if it'll work at all) but I have done this same fix for a BSoD'd phone... and it worked.
Let me know if you've got other questions, I'll be happy to help.
