Are they swappable?
i.e. Can the mainboard from an AT&T Play go right into a Verizon chassis/screen/digitizer? Is there a plate over the hole for the SIM in the Verizon chassis or do you need an AT&T back too? Are there other issues anyone can make me aware of that might scuttle my plan?

Yes you can swap motherboards because everything else is inerchangable. In the verizon motherboard the slimcard slot is plugged up from verizon though and it can not be removed. (They glued it in)
Everything will swap just the same, except on your Att housing you will need to remove the antenna's and place them onto the r800x housing. I the main antenna is not really the same, I experience poor 3g using the housing from a r800a on my r800x, and your att phone has an antenna that the verizon phone does Not have. Other then the antennas you will be ok.
I know someone has tried the Sprint S3 Screen assembly (didn't fit due to lack of SIM card slot), but however did anyone try the Verizon or U.S Cellular S3 Screen Assembly (due to the fact they have SIM slots)? My LED screen is cracked on mine. I was just trying to see if maybe if these 2 phones can interchange screens with each other. I have pics of both of them, and they look pretty similar. I am trying to find the USC S3's digitizer assembly now
T999/I747 Screen Housing (right), and Verizon I535 (left)
EDIT: Just found the USC S3 Assembly:
Tell me what you guys think
I'm wondering if anyone has any thoughts as to how I should proceed. I purchased a close to mint s4 that didnt read the sim card. It was cheap and I needed a screen for my s4 that I cracked. I tinkered with it a bit before tearing it down and other than no sim error the phone seemed to work flawless. When I did the tear down I noticed the internal screen housing was i337 stamped. The circuit board for the charging port was as well. The mainboard was stamped i337/m919 but the sim slot was stamped gt-19505. the imei on the sticker doesnt match whats in the settings. The sticker says tmobile but a search of phone info online shows the imei in the settings is from a i337. Does anyone know if this may be a possible flash thats wrong and the board was actually at&t? I'm aware you can change the meid easily and that may be it as well but im hoping maybe there is some software I can push to read if this is the case. I did order a sim slot to put in this evening and see if the slot is just bad. My old screen is not cracked bad and works without any issue so I would like to get it resolved and just resale it for parts on ebay is my plan if I can get the phone straightened out.
tldr-will flashing at&t rom brick the tmobile since the hardware is basically identical? Is there any way to tell if the wrong rom has been flashed to the board?
Booting into dl mode shows m919 and that knox hasnt been tripped. write protection enabled and emmc burst mode is enabled so I'm going to assume its not been flashed.
Hi everyone! I have a quick question. In the process of trying to replace the broken screen on my S3, I ended up breaking the LCD/Digitizer -.-
I was on the hunt for a replacement i747 so I could switch out the motherboards, but on Ebay, I saw a listing of a Sprint phone that had the i747 motherboard inside of it. So my question is, could I place my motherboard inside any of the S3 variants and it will work? I know it will work with T-Mobile, but what about Sprint, Verizon, etc? Thanks :3
Nope. It won't fit.
The sprint version lacks a Sim tray so that's One incompatibility
Thanks for the answers! I'm guessing the phone I saw actually just had the Sprint LCD in the i747 housing. Or something like that. Either way, I just decided to buy another cheap i747 and switch out the boards. Thanks again

Ya I checked that its same as my buddy note 2to same carrier. AT&T
Weird! I've been having the same issue lately.
In my case, cellular reception became spotty (completely losing connectivity in areas where I'd never previously had issues in my two years with this phone), and then cut out permanently after I dropped the phone fairly hard. I replaced the antenna (not an easy part to acquire, as I went through three ebay auctions before someone finally sold me the correct part) and it was spotty again for about a week before completely dying out again. I started using a backup phone out of frustration before finding another fully functional SGH-i317 for sale on the cheap, and I ended up combining the parts from the two to make a working phone. One day in, and the only issue is that the phone fails to regain cellular connectivity after leaving a dead zone (a few resets have so far done the trick)
Anyway, I'm far from an expert on this, but just to get the conversation going, here are some things I noticed:
Both my original Note II as well as the used one I purchased are 16 Gb SGH-i317 (AT&T GSM) models stamped N7105 under the Samsung sticker in the battery bay. Both used the OEM blue antenna wire (some Note II variants apparently use white wires of the same length), and the smaller boards at the bottoms of the phones which the antenna plugs into (with the charger port attached) are stamped SGH-i317 rev0.7 R.C94(KH) 25. The only difference I've noticed is that the new model is stamped "LTE #1" on the bezel underneath the motherboard whereas my old one was stamped with a different number (which of course I can't remember now that I've reassembled it)
Not sure if any of these weird little specifics will help anyone else who is having the issue, but I figured I'd put it out there just in case.
For the record, I'm in the same boat as OP after having reset/restored a few times. I also hadn't installed anything new/ominous or modified anything prior to the issue occurring originally.
Thank you.I also read in another thread that the modem drier may be corrupted. So the phone can not communicate width modem.

One other thing if there's a place you can take it to and have them check the sim tray?? Might be a possible fix??

I would flash the current AT&T modem, then use a few APN'S until you find the best for your area.
Iv been trying the different modems and apns.no luck so far.
Im going to do as Benjamin said and have sim slot checked.
Although it seem it is working because.it shows son when installed.
And nothing when out
You don't mention flashing any custom roms or updates, but assuming you have, the best way to troubleshoot your phone would be to return your phone all the way back to stock. This strategy has cured baseband, gps, headphone issues etc.
Lost Cell Signal after replacing charging port connector.
I have a SGH-i317 NOTE 2 and am experiencing the same issue after replacing the charging port connector.
does anyone know if the charging port connector is related to cell phone signal strength? After replacing this part, i cannot even get a signal indoors and only a weak signal outdoors.
