I have an old Galaxy S3 that was used on the Virgin Mobile network. The phone sat in a drawer for a long while as the charger port was broken. My son picked it up, took it all apart and looked up replacing the logic board inside the phone to try and get it going again. (I love his desire to get into the guts of it.)
He found S3 logic boards online that have the SIM card on them (VM's are hardwired somehow). I am not a hardware guy at all, though flashed ROM's many times in the past. If he replaces the logic board with one that has a location for a SIM card could we put a TMobile SIM card in and would it work? (I suspect we would have to find a TMobile S3 ROM as well??). Not sure how the interaction of the SIM card with the phone works.
Any ideas would be greatly appreciated....

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.

I just bought a used G2 for my son to be used as a wifi phone. I successively rooted and have Andromadus jellybelly on there. The phone was sold as unable to read the sim card, and I am wondering if there is a method to figure out if the reason is software related vs physical/hardware related? Any suggestions on what to try?
If it didn't work stock and still won't work after tooted and custom rom I doubt its software/firmware
So that leaves hardware, it seems the sim tray comes detatched from logic board on some of these, you can try and resolder the tray or pick up a new one. Possibly something else but it will be hard to determin other than trial and error

Look at the contact pins in the sim slot, make sure that they're straight and "up". If there are any that are bent over or not sticking up properly, those aren't making contact and therefore the sim won't work.
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.
Hi everyone,
I am having a little issue. I recently updated to KK and jut didnt like how it preformed. I .toted back to ZV7 to start fresh, this is when I noticed I had a sim card in my statusbar with a little X on it. Then I noticed that I had no LTE. I can't figure out if I did something wrong or what.
I had one of my developer friends walk me through a few things that he had to do on the G Flex, which was toting 5 or more time till that sim card was recognized, well mine still doesnt work. heck I even went into Sprint to have them check it out, and all they did was replace and scan in a new LTE card.
Could me Sim slot be turned off? or could it be fried?
I have had this issue sort of
i have had the lg g2 on sprint for about two months and i occasionally get a similar issue except it just says that there is no sim card inserted however my LTE is completely un hindered. and it would normaly correct its self after a couple reboots. is your device damaged in anyway and how long have you had the device,
It corrected itself over multi reboots. several days worth of reboots. The phone is now ongoing its 3rd week in immaculate condition. and its been babied, so no damage whatsoever.
Hi all, I have a Samsung S3 GT9300 with a damaged board, phone won't connect or charge. I bought a used board, owner said board is OK and unlocked, phone connects, charge and works (wireless OK) but when I put the SIM in the phone keeps showing a message: No SIM card with the no SIM card symbol, doesn't ask for pin number either. Strange thing is that the network signal is normal. I have replaced the SIM carrier but it's the same. I don't know what I am missing here and need some help.
I'll put some pics of the message soon.
Thanks in advance.
