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.
Hey guys, I have a Galaxy S3 from Wind (T999V) It worked perfectly fine for over a year. After the warranty was up, I decided to root since I didn't really have much to lose. I flashed everything from, CM to Illuzions ROM. Everything worked great. One night I was on the phone with my girlfriend, we got off around 12. I put my phone on charge and then the next morning I woke up around 6:30, checked my phone and all was still good. Then after taking my dog for a walk, I checked once again at 7:30, and I was not connected to wind anymore. I turned airplane on and off, hard resets, unroot and back to stock. I have actually tried everything. Spent hours upon hours with wind tech support, and they even gave me a new sim. Went to a warranty center to pick up the sim and even with the new sim my phone wouldn't work. While there, I asked if they could try the sim in a different phone, and it worked in the other phone, so I'm pretty much certain its a hardware issue now, though it worked perfect for over a year,
Can someone please help me, PLEASE?!?!?!?!??!?!?!!?!!?!?!?!?!?!?!?!?!???!!??!!??!!??!?!?!?!?!?!?!
P.S. Already tried to manually select a network, All it will find is Wind Away. I put in my friends SIM from bell and it got bars, connected to the network, just wouldnt let me place calls because it is locked to wind.
Sounds more like an account issue to me. Find someone with a wind phone, and try their SIM in your phone. The way it sounds to me after testing with the Rogers SIM, is that the device is fine. If it were hardware your friends SIM would have done nothing more than yours.

Yea, but when I went to the wind store to get my new SIM, they tested it out on another device so I know the SIM is working, so wouldn't testing his SIM on mine be the same as testing my SIM on any other wind phone?
No idea. All I know is you mentioned that when you tried a Rogers SIM it seemed like it worked, or would if unlocked. Only way to know is to try another SIM on your phone. Could be an account issue. But if it appeared to work as expected with his SIM, that tells me it's probably not hardware.
Maybe a wind tower is having problems....

I have root, thats it, i get NO SIM in the notifications and have no data. Every now and then I would be able to restart to fix it,but now it seems its working either. ICCID is unknown in About phone. Everything else seems alright.
This is almost a brand new phone, only rooted. Had no new ROM installed on it. I restored it to the very first backup i made after rooting, same issue. I have a pending 4.3 update,which I have not updated yet.
Any idea what's going on ?
No one?

My son was having issues with his HTC One's SIM card. Data was sporadic, no LTE, and he would get no SIM card errors. We took it in to the Sprint repair center in the area and they first tried blowing out the SIM card slot but ended up putting in a new SIM card which fixed the problem.
Hopefully the person who looks at your phone is competent as we had to make a few trips as we were told at one point that we didn't even need a SIM card since we were not going Global - this older guy was wrong. We ended up having this young woman take a look at it and she swapped it out ASAP and we were good. I'm going on a bit but I was somewhat floored that their repair tech gave info that was just wrong. I've had to go back a few other times (for other reasons) and I avoid that dude at all costs (straight to the young woman).
Unfortuantely, on note 2 the sim card is not even accesible. Its buried/sealed inside, unless sprint techs have a way to access it.I am surprised this is such a low occuring issue, that no one in this forum has this.
Same thing
Same thing happened to me 2 weeks ago, i had to order a new card

The "techs" there are a joke. The only people who can REALLY help are devs who they probably keep locked away in a safe house abroad. There hasn't been a single time when a phone carrier tech was remotely helpful for me.
And the SIM is on the same module as the SD card. IIRC they can swap out this entire module. How will they replicate the same iccid onto the new one? No clue. If they replaced it and your issue was fixed though they did it somehow. Or else your authentications would be all messed up (meid> mdn>min>HDR AN>profile 0 and 1>iccid...probably more I'm forgetting)

So i got my note 4 in the mail and i put the sim card i had in my gnex into the phone. Now when i use the N4, i dont connect to LTE, im only connected to 3g. Ive tried switching it to LTE/CDMA but it still wont go. Anyone have any ideas how to fix it?
Glad I'm not the only one having this issue. I called Samsung after trying everything at the Verizon store, including replacing the sim card, and they had no idea. All this means is I get to delay the phone swap another 9-13 business days according to what Samsung told me. Hopefully by then the wizards on here will work their magic and have us not only root but a custom rom to flash. I don't mind TW but I really prefer the control of a custom rom.

idk if it'll help, but a factory reset might do it. Just a suggestion.
Tried that and still no 4g. I've also tried three different sim cards. Still no 4g. Only real option is to get it fixed. Oh well. Still loving my note 2.

If you ask me, it sounds like the 4G antenna isn't working properly or it could have been a bad batch of phones.
OP Here, i got the problem fixed so heres how.
i plugged in the sim card that came with my phone and noticed that that sim was connecting to 4g, but didnt have a number attached to it. i called verizon and the dude switched my phone number onto the new sim card and now all works fine so if you dont have lte try that and good luck.

Yeah unfortunately that didn't work in my case. It's on it's way to being fixed or replaced by Samsung. I'll have it back in a week or so. I've waited this long for it what's another week. Still have my rooted, romed, and custom kerneled Note 2 to use until that comes back.
I purchased a used Note 7 and it is locked to Bell Canada. I tried several unlocking services online to get an unlock code but all of them have been unsuccessful, they can't find an unlock code. Is there any other way to SIM unlock the 930W8 Note 7? Or is there a way to switch SIM lock from one carrier to another?
I haven't been able to use the phone because of this
Question: when did you purchase and why?

How is that going to help him? You just want to be able to upset him if he says he purchased it post-recall?
Anyways, to the OP: It may be a long shot, but try to factory reset it without a SIM card installed. Then Factory reset it again after that WITH your non-Bell SIM card installed. I know what everyone is thinking: "wtf?" BUT...
I am suggesting this because when I got my "replacement" Note 7 after the first recall, I kept the SIM in the first phone while I set up the second phone. I used Smart Switch and installed all the apps again. One thing I noticed is that it didn't have my carrier's bloatware on it at all. It was like a phone purchased directly from Samsung to be carrier-free. After that, I removed the SIM from the first phone and installed it in the second phone. As soon as the second phone registered the SIM, the phone shut itself off, and factory-reset itself! Once it came back up, the phone had been wiped, and suddenly had my carrier's apps on it.
Because it is a recalled device and has been banned and probably will be disabled entirely quite soon. Needs to find a substitute phone.
But thanks and good luck on the advice!

Thanks for the suggestion, unfortunately it did not work. I believe the phone locks to the first carrier upon SIM insertion. It is normal for the phone to factory reset when you insert the SIM as it needs to load carrier apps / settings. If you can think of anything else to try, let me know. I'm trying to be hopeful...
