Introduzione
Use this guide to replace the I/O daughterboard in your Samsung Galaxy S8. Components that would warrant replacement of the daughterboard include a damaged USB-C connector or microphone.
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.

Something you should add is that the battery temperature sensor is actually on the wireless charging coil. Unless you screw that part on, adding a new daughter board and plugging it in will result in the phone thinking the battery temperature is too low and thus it won't charge
Hi i just change the motherboard and the battery is new the display show ( ! ) is not working. Can you help me to solve the problem. Thank you
Step 22 does not apply to the Samsung galaxy s8 SM-G950F, the daughterboard is different and does not have that connector for anyone trying to source one !
sm-g930F, daughter board does not have the 3mm screws .it seems to use an elastic at each en to hold in place. has anyone successfully replaced this daughterboard?

That battery temperature thing really confused me while testing as I put things back together. Makes sense it worked fine when I put back together after I'd had enough.
I found the finger print reader easier to put on after removing it from the case. My finger print reader didn't work after I put it back together. But started working the next day.
I found it easier to connect the motherboard to the daughter board when the daughter board is fixed in, then you just hold the motherboard vertically, click them together and tilt the motherboard back into place while using something to poke the flap connectors out the way.
Those two wires/ arieals? They loop under the motherboard for when the speaker goes back on.
As you're testing as you put things back together, the volume buttons only work when everything is screwed back in. I've come across this before on other samsung phones, killed me the first time trying to figure it out!!
