Can I swap the motherboard?

[roguegc]

Hello! I joined the forum to ask for some help. Ive watched youtube videos and am pretty confident that I can take apart my HTC One M8's. I have two. One is a an AT&T prepaid monthly card activated phone. The other is the Harman Kardon edition HTC One M8 on an old Sprint plan i had. The one i am currently using, is the AT&T prepaid. The screen on it is busted pretty bad. Im a welder/fabricator and decided it would be a good idea to put a grinder through part of the screen, and through the top speaker. The screen is slowly getting worse and going out. My question would be, since the other HTC phone i have works perfectly fine, however i do not want to use sprint as a carrier, would it work if i were to swap the AT&T mother board to the other phone? AT&T mother board to the Sprint phone.

One sort of MAJOR problem. The AT&T board has GSM hardware on it, the Sprint board has CDMA hardware on it. Putting the Sprint motherboard in the working phone will turn it into a Sprint phone (even if you change SD cards, etc.).

Im trying to switch the working at&t mother board into the sprint phone. not the other way around. would it be better if i just swapped the screens? and left the motherboard alone. i can live with the gash in the speaker.

From what I remember seeing in teardowns, the plastic speaker covers can be removed with a guitar pick (after heating with a hair dryer, carefully) and then screws will allow you to remove the display assembly.

Ifixit has a teardown of the HTC M8. It recieved the worst repair ability score possible at the time. I was right about the speaker covers, but the screws actually remove the rear casing. The rest of the device is bundled together inside for you to tear down.
