Samsung Galaxy S8 Motherboard Replacement
Введение
Перейти к шагу 1Use this guide to remove or replace a faulty motherboard.
This guide involves removing the rear glass cover, you will need replacement adhesive to reattach the back cover to the phone.
The motherboard and daughterboard will differ slightly depending on whether you have the North American Snapdragon (G950U) or international Exynos (G950F) version of the phone. This guide uses the North American version. The motherboard and daughterboard are not interchangeable between the two versions.
Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

does the size differ between s8 and s8+?
can i use s8+ motherboard for s8?
Hi Ginthozan, unfortunately the S8+ motherboard is not compatible with the S8, and vice versa.
Are all the connections and motherboard layouts the same for Sprint vs AT&T S8?
Hello i can’t charge my phone (both directly and wireless). I still can turn on my phone by charging it directly to the battery. I have replaced my chsrging port flexible but it didn’t works. I think the ic is broken. There’s two PMIC for s8, PM8998 and SM5720, which one that i should change if i can’t charge my phone? Thankyou
After change my LCD and the motherboard the display screen (!)
