[Q] SGH i747m - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

A few days after upgrading to 4.3 my phone stopped reading my SIM card, says Unregistered SIM. I figured the sim card got fried as the phone seemed hotter then normal when I was playing with it while it was charging, so I picked up a replacement sim card though Telus. When I installed new card still had same issue, I chatted to Telus online helper and they suggested my phone may have been flagged as lost or stolen.
I purchased the phone used back in June, it was originally a Rogers phone but I used the key code unlock to unlock it and it worked fine for 6 months. Now when I use Telus compatibility tool it says my phone has been blacklisted as lost or stolen... is this even possible after 6 months? Telus said they cant help as it is a Rogers phone, Rogers won't help because I am not a customer... I don't really believe the phone was reported, but don't get how it ended up on the "Blacklist", I wanted to rollback from 4.3 to 4.1.1 so I could start from scratch but see warnings that it will brick the phone if I try to do that.
Is this a common problem with the 4.3 update, if so is there a fix? If the sellers did wait 6 months to report phone lost or stolen, is there anything I can do to get the phone working again if they won't message me back? I have some of the back and forth messages setting up the deal for the phone, they haven't responded to any of the messages that I have been sending them
Phone is a SGH i747m

Unlock/Root befor Activation

I unlocked my phone, rooted and loaded up JB.
I went into verizon today to get a sim card. The rep could only get the internet to pull data no voice. Is it because I unlocked it and all that it doesn't work?
No it shouldn't be.
Has anyone heard of this problem?
I'm in the Netherlands so I don't know anything about Verizon, but I fail to see how having an unlocked bootloader can interfere with the service of a carrier.
i dont think having it unlocked would cause these issues. However, just to start to rule things out I would return it to 100% stock to see what happens
Turns out the guy I got it from still have the imei under is account as active . Called him and he took it off tried to activate it and blam. Yay this phone is awesome

[Q] Need help :(

i just recently got my unlock code for my 900 and once i unlocked it everything went well for a week. Then suddenly(not sure when it happen) my phone stopped reading my sim.. I just got this new sim a couple of days ago from tmobile and it was working fine, but now the phone doesnt read any sims, ive tried 3 so far and no luck. Ive even flashed the oem rom back to it and still no luck.. Not sure what to do now. But the phone still picks up wifi and works normally besides no reading sim cards.

Doesn't matter if it's unlocked, or you don't have an at&t account. Pop in your IMEI to check warranty, fill out the form. Nokia will send you a PDF with instructions and a free UPS 2 day air label. Ship it to Nokia, they'll fix it in a few days and mail it back 2 day air. They have great CS. Someone will call you before you ship it to see if you have any questions, then when it comes back the same person will call you to do a "Health Check" on the phone making sure the issue was resolved. I just did this last week or so on my unlocked 900.

Unlocked GSM Galaxy Nexus - No signal al all

Hello,
A bit about my Nexus: Bought it online, it's the Domoco version, unlocked, rooted and been using just fine with many custom ROMs.
So yesterday morning, I was talking on the phone with a friend without any problem. After hanging up for a few hours, when I was about to call someone else, I realized my phone didn't have any signal at all. And it has been like that until now, about 48 hours.
It happened so suddenly without any warning. The phone has never been dropped and everything else working just fine.
So here's what I have tried:
- Restart the phone (multiple times)
- Batter pull (multiple times)
- Factory reset the phone (multiple times)
- Wipe cache and dalvik cache in CWM (multiple times)
- Downloaded SetCPU and set the minimum to 700Mhz (instead of 350Mhz)
- Reflash the ROM and tried with other Custom ROMs (I tried Xenon, Xylon, PA, and Carbon ROMs)
- Reflash the Radio and tried with other Radios too (I tried UILH1, XXLH1, SC04DOMLE3 and some others ...)
- I also went to Tmobile and request a new sim card - same problem.
- I borrowed a sim card from another Tmobile customer to try it on my phone - no signal - but the sim card works just fine on his phone.
I ran out of thing to try and I dont understand what happened ... anyone has an idea or something else for me to try ?
Anyone experience this before ?
Welcome too my hell. I have a playstore one now but my first Gnex was an international one and it has this same issue. Its a PCB problem a warranty would fix. I'm near Chicago and a few people have told me there is an electrical engineer downtown that fixes stuff like this. I don't have a price but I think something like this is your only option. Mine sadly is still a battery charger:thumbdown:

I know it sounds stupid, but have you tried toggling airplane mode? I run into the occasional loss of signal when im at work [fair to weak signal in the big metal box], and a reboot is the only thing that fixes it for me. Mines a play store model.

Ah yes, I actually did try that too but forgot to mention. I tried toggle airplane mode on and off, also the 2G only mode on and off. But it didn't help with anything.
Thanks for the suggestion.

So I guess I have to look for an electrician then, cause I have this phone just a little bit over a year so warranty is a no go for me.
Thanks for the idea.
PS: anyone else has more option for me ? I just wondered if I have bricked my phone ... cause I flashed lots of diff. ROMs to try out but never gotten a bricked phone before, could this be a bricked phone ?
Bricked refers to a phone that does what a brick does: nothing. It doesn't boot, it does not light or attempt to boot, it does nothing. This is a signal issue..I have no prior experience with docomo, but this thread came up on search: http://forum.xda-developers.com/showthread.php?t=1574018, maybe it'd be helpful. Have you converted it to yakju or takju and tried a google factory image?
And this: http://forum.xda-developers.com/showthread.php?t=1554150. If it is a circuit board, it kinda looks like s.o.l., and im sad to say that to you.
I wanted to let you know that I experienced the same issue. I bought the unlocked Docomo Galaxy Nexus, and had it working fine on T-Mobile for half a year, and then suddenly had no signal on Tuesday. Nothing I did - factory reset, battery in and out, sim card in and out - could fix it. Have you tried using different sim cards in your phone to see what works and what doesn't?
I figured out that my phone will accept AT&T, and actually does connect to T-Mobile while roaming (I used an international sim card). But, my phone will say "Cannot find mobile network" when any T-Mobile sim card is inserted.

I also have the same problem with the docomo phone. ATT Sim card works. Tried other's T-mobile sim cards and it doesn't work. I wonder if somehow the IMEI has been blocked by T-mobile.

I know others who bought their GNEX through the Play Store and those work just fine with T-mobile. I tried their sim cards in my phone and it doesn't work. I don't think T-mobile is intentionally blocking the docomo phones, because I'm getting T-mobile through roaming, when I use an international sim. My guess is they're doing something to the cell network that just somehow leaves our configuration out. Hopefully it's temporary, but who knows.
Worse case, I'll just purchase a Nexus 4, because I love 4G data for just $30/month with T-mobile. Anyone else got suggestions?

Alright, update on this and there' good news. I called Tmobile and they said my IMEI is actually Blocked. The reason, according to him, is that Tmobile usually sweep the network to clean up all "un-supported" devices, so my device is apparently one of them and therefore got blocked about 2 days ago.
So he said for this, he needs to escalate it to business support and they surely can unblock it for me, but I have to wait until Monday since they don't work on weekend. But well, that's surely a good news. phewwwwwwwwwwwwww !!!
So to all of you guys who are in the same situation, make sure you call Tmobile first before flashing crazy like I did LOL.
Thanks for all the help.
I'd love to know if you are able to get this unblocked and working as I have the same problem as of Tuesday. I was traveling and went into a TMO store, and they told me it was NOT IMEI blocked. In fact they looked at the IMEI and read the page and said 'it was not eligible for blocking'.
I called TMO to see if my phone is IMEI blocked, and through three levels of support the universal answer was no. I'm now fully confused because if it's a hardware issue, why did several people all have the same problem all on Tuesday. For those others who are having issues, can you see the TMO network but not connect to it? That's what I have, I can see TMO and AT&T but haven't been able to connect to either one since Tuesday.

I'll call up T-Mobile tomorrow and ask if they IMEI blocked my device. I had them reset my signal and give me a new SIM card, but didn't realize it could have been IMEI blocked. I'll give them a call on Monday and let you know what the result is. Maybe it won't be too late to cancel my order on that Nexus 4...
I'm quite confused. I've been told last Thursday in a TMO store and with tech support that I didn't have an IMEI block, and the same with three reps tonight. I know the Sim Card is good, and so I'm being told its a hardware issue. However, several of the same phones had the same issue on the same day, so I can't buy it's a hardware issue. Has anyone with this issue flashed a new or different radio into the phone, either before or after the service loss? I have not, running it as it came out of the box.
I just got off the phone with T-Mobile Support, and they told me the device is not blocked. The reason is that T-Mobile cannot block or unblock devices that are not registered to T-Mobile. So I'm back to square one on this.
chowabbajack - When did you first have a problem, last Tuesday? Did you prior to that do any flashing or radio changes to the phone?
We're in the same spot....

I did not do any kind of flashing or radio changes prior to Tuesday, when I lost signal.

That makes me think its something to do with the radio software, because I am the same the problem overall doesn't seem as large as the number of phones I perceive were bought on the Docomo deal.
Ive been using the docomo version of the nexus as well on tmobile for almost a year and it was since last tuesday when it no longer recieved any singal. with some digging around and too many phone calls, I found that the imei number on the phone is not the same as the one under the battery. i have the generic 004999010640000 imei right now and it not sure how i got it. as i bought it unlocked.
what i have tried:
reboot, battery plug, reinsert sim, factory reset, root and flash, got a new sim card, relocked, unlocked
sim card works on other phones.
also i have called tmobile and samsung endlessly and this is what i got:
tmobile cannot unblock the imei since it is not from them.
samsung is redirecting me to their japan branch.
docomo i cannot reach.
my phone before last tuesday:
unrooted stock 4.2.1
been testing different things to see if there is any way to restore the imei
also using root explorer, i cannot find my efs folder....
I've got the same problem since last Tuesday with my GNex and T-Mobile.
Mine is not from docomo though, but the French phone provider SFR, unlocked through FDocomo apk.
Rooted phone, running 4.2.1., no changes whatsoever in the past month and it worked fine until Tuesday, so I don't think I'm responsible for having no signal.
Honestly, I am relieved to see we are quite a few to have this problem, and also very pissed at T-Mobile for causing all this. What should be the next step then? Is there any chances they fix the issue quickly? If not, I might just go to the competition. I've tried AT&T sim cards and they work fine.

I have the exact same generic IMEI number as you, which does not match the number under the battery. I'm not liking the news that you did flash and still no go. I'm a novice at this stuff so please keep us posted.

[Q] Getting no service anywhere

Woke up this morning to see that I'm not getting any service, I was running CM10.1, everything was fine and this morning I stopped get any signal anywhere whatsoever.
I am on Bell Mobility (Canadian Carrier) on the SGH-i747M, ever since then I have tried anything that could come to mind. Took out SIM card a million times, flashed back to stock, etc. but I'm still stuck in the same situation.
I went to a cell phone kiosk that handles several Canadian carriers. The guy looked through my phone, the phone is unlocked so he tried his Telus SIM card and ended up with the same results and then tried another Bell SIM card but no luck there either so the problem is definitely not the SIM card.
I'm assuming I can send this to repairs and I am still under the 12 month manufacturer warranty, but before I do that is there anything else I can do to save this phone?
so you had service on cm10 prior to this? it just went out without you doing anything? you checked your imei?
You can find your imei under the settings/about phone/status. If its not there no worries as long as you still have your box with this information. Search for imei recovery in the forums.
Best of luck.

I have been out of the game for a while but I was hoping one of y'all could help

My son had a T-Mobile branded S20 5G and I moved our service to Verizon. I paid his phone off and got it unlocked. Everything was working fine up until a couple of weeks ago. He did an update (didnt pay attention to what kind of update) and now he cant make or recieved calls or text (keepin mind the phone was working fine before this update). Attempts to call result in a message from Verizon saying that they cant authenticate his phone.
I *****ed at Samsung for a bit since his phone isnt rooted and even though its over a year old if a software update bricked it, I felt like they should have some ownership of the issue. It was a waste of time so now I'm back on the phone waiting for VZW tech support.
I think the issue is that its a TMO branded phone on VZW's network and everyone is pointing the finger at everyone else. My question is 2 fold.
1) has anyone ever experienced this before, and if so what did you do to resolve it and
2) I will attempt to root it and flash a ROm on it before I entertain buuying another phone.....hes got enough other **** hes dealign with financially he doesnt need to add a new phone purchase to his plate.
Any help would be much appreciated because I'm pissed the eff off at this point.
Yes we tried different APN settings...he walked into a VWZ store and they were able to get his data working but not voice or text....seems like something is out of whack with his radios). We also did a full factory reset.....same issue persists
I am not an expert on ROMs but I will give you my two cents. When I was playing with my unlocked phone, I realized that mine updated some CSC binaries as soon as I inserted the SIM. I saw some message for it updating the CSC code from XAA to TMB when I inserted TMO SIM on stock firmware. So my suggestion would be to try downloading VZW stock firmware from samfw.com and installing that.
