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.

Well, my SIM tray holder is broken, I can see a small spring and my SIM doesn't stay in. I have tried to get the same part for the S3 t-mobile but can't find it.
I found the international one, SD SIM tray holder for i9300, but wherever I go, the only say to be compatible with the i9300. Does anybody know if I can use this part on my t-mobile s3 ?, the parts look the same (at least to me).
Thanks for you help
If I am correct you still have a year warranty thru manufaturer and TMO will replace device. My daughter had a BB Curve and about 9 months in starting having rebooting problems and they went ahead and replaced it 3 times and on the 4th gave a crazy discount towards another phone. More than likely it will be refurbished unit not a new one. Refurb has got to be better than buying a part that you would have to install yourself and possibly mess something else up. We did not have insurance on that phone either. So if you bought thru TMO call them up.
As long as you're the first owner/first to register service with T-Mobile with that phone, you can claim the warranty.

Hey all,
I told a friend I would replace the digitizer on his AT&T Nitro HD. The replacement went fine, but when I reassembled the phone and powered it up, it had no service and the "No SIM Card" icon is on the notification bar. I took the device back apart and reseated all the connections on the motherboard. Before I put the back housing back on, I put in the SIM card and battery in and powered it up to test real quick. The phone booted and it had service! I reassembled the phone and booted back up and there was nothing again. I have tried reseating connections again but still nothing.
I have been looking through the unbrick guides and I'm considering flashing a factory image to see if that will correct the problem. I'm fairly sure the problem isn't with hardware. Could the SIM card have been corrupted also?

It's possible that something happened to the sim card. Do you have another active sim to try?
Not a full size AT&T card. I only have access to VZW and T-Mobile micro SIM's.

A micro sim will fit inside the sim slot but it has to be positioned cardfully. You could also get a micro sim to full-size adapter.
If you can flash a stock rom try that and see if that fixes the problem.
Damaging the sim shouldn't male the phone lose its imei. Did you look for it by dialing *#06# or under About Phone?
I have everything ready from one of the unbricking guides to start from scratch, but I would want to back everything up first before going that route. I checked the Settings and *#06*# and they both say unknown/blank.

Maybe try updating using the official LG updater using recovery mode. Make sure to set your country and language. The imei should be on the label underneath the battery.
I actually tried that last night. Upgraded to V20c using the LG Update tool in recovery mode. The IMEI still wasn't present. He is just going to take it down to an AT&T Store and see what they can do.
It was a good effort on your part, that's for sure. I hope your friend has some luck with ATT. Is the phone under warranty? I'm asking because you had to replace the digitizer.
No it's not. I was hoping to get it fixed so I wasn't on the hook to replace his phone because something went wrong while I had it apart. I'm hoping they can take care of it with minimum charges or allow him to upgrade early. Thanks for the advice.
No problem. I just hope they are able to help out your friend.
It's strange that something like that would happen because taking it apart is pretty easy. Maybe something happened before you replaced the digitizer.
good afternoon all, just recently i stumbled across something that made my eyebrow raise... i has a purchased NOTE2 from ATT (I317), but a while ago it was having antenna reception issues. i got it replaced with an "ATT Refurb" unit.... heres were it gets interesting
just recently the thread was posted for the registration and get free stuff from Samsung, im sure we all tried it...
well under my battery was a sticker with a model number (SGH-I317), IMEI, SKU, and FCC ID number, but no serial?
so when registering i used the serial found on the same page as the WiFi MAC, and Samsung didn't like it?
the wife also has an ATT note 2, but weird, under her battery was all the info printed actually on the plastic?
made me wonder why i had a sticker? so i pealed it off only to find under the sticker was the stamping saying i was actually holding a (N7105) unit????
that explains why it works on ATT with out any issues, but go me thinking, does that mean i should be able t use the roms and ODIN packages from over in the N7105 forum? or has ATT flashed some kind of partition making it think its just a I317, and i could possibly brick if i try and flash N7105 stuff?
also makes me wonder if anyone else that has gotten a refurb unit has found out the same thing? and they infact have an N7105 unit too?
went a step further and booted into DL mode (power down+home+power)
ODIN MODE
Product Name: SGH-I317
CustBinDL: Yes (1 counts)
CurrBin: Custom
SysStatus: Official
maybe i answerd my own question and should stay away from N7105 flahes? darn, thought i saw freedom for a second...
N7105 and i317/i317m are pretty interchangeable. Most of the time the only problem is having modems included in the roms IIRC
There might have been a broken case and you got a international case on your at&t guts, which is why they slapped on a sticker.
My note 2 shows no bars with a good sim card installed.
and has no service what soevevr.I was thinking its the
radio.but when I remove sim it shows signal and can make an emergency call.
Im stumped.I even Odonda back to stock no help.
any ideas before I start replacing hardware.
iv tried other sim out friends phone and using my sim in backup phone.
Warranty is expired.any help please

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.

I'm not sure if this should be posted in the 710 forum or here, but I want to end up with an I747 so that's why I picked here.
I have a perfect, absolute mint condition 710T from Boost. It's not even 6 months old. But I don't like being stuck on boost, and I liked being able to swap sim cards/phones when I was on GSM. I have the option to obtain, cheaply, a rather roughed up I747 from AT&T, which is unlocked, but also has a broken lcd.
My question is, since I would have two complete phones, is it possible to put the I747 guts into the 710T shell? I know that the motherboards are slightly different. The biggest difference I've found from looking at pictures is that on the I747, on the lower part of the skinny side section there's a (roughly) 3/4 inch long metal piece, where on the 710T there's some little square things instead. Other than that they appear to be the same except for the obvious lack of a sim card slot on the 710T. The antenna location and connections look to be the same also.
If this type of swap is possible, would I only need to change the motherboard and the midframe (the part with the SD and sim holes)? Or would there be other parts I'd have to change also?
I searched both the 710 and I747 forums but didn't find anyone doing the same, except one guy who only had the motherboard of an I747, and not the whole phone, so of course he wasn't able to do it. Any insight is greatly appreciated.
