Chosen Solution
I have a Galaxy Note 5 N920G that has a water problem, everything just fine apart that it does not recognize the sim, so for calls and data is useless. I took it to Samsung , and they said that the motherboard or logic board does not work and need a replacement, but they want to charge me 300 usd that´s like a brand new note 5. Anyways browsing through eBay there are some boards but with different prefixes such as N920 A, V, T, N etc. I wonder if it will function with my cellphone? Will it be easy to replace the board? Also im from Mexico if that helps.
Ok, so here’s a guide on how to get your logic board out, and a guide to treating it with 90% isopropyl alcohol. With that being said, you may want to bring the board/phone to a reputable repair shop, with an ultra sonic bath. That’s really the best way to clean the board https://m.youtube.com/watch?v=SsGcdIMCSg… Electronics Water Damage
