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.
Hi everyone,
I have, hopefully, a simple problem. I recently upgraded to a galaxy s4 from the s3. the s3 is a year old as my corporate contract allows me to upgrade my phone every year. so I am with bell, and my wife is with telus. she wanted my s3 since she has the iphone 4 and is sick of it. I updated the software on the s3 about 3 weeks ago so some of the threads on here wouldn't work for unlocking it. I went to the cell unlocker website and paid for a code. I still have the email they sent with all the codes, unlock, freeze etc, and it worked. I put her sim card in and could text and call out. the phone says telus where it said bell before. however the data will not work. Wi-Fi does but mobile data will not. we went to a telus store, they upgraded her sim card but to no avail. I tried searching for threads here but didn't come up with something like this. the phone is stock, no mods or anything, I even reset it back to factory settings, sim still works just no mobile data. I tried to get bell to unlock it before but they said they couldn't cuz it was tied to a contract.
I hope someone has seen this before and can help because i'm at a loss.
thanks for any ideas

Have you looked into the APN settings? I have them around here somewhere. I can locate them and forward them to you if you'd like. You can also find them right on the Telus website. I'm thinking that's a good place to start.

that would be awesome, thanks. I know the rep for the telus kiosk at Devonshire mall went in to look at a few things, but he wasn't sure and google what was happening but he said it was all at&t stuff, then gave me back my phone. but yeah I would appreciate the info. not sure if my email shows or not but it is [email protected]. I will try that out and post back as to what is happening.
Hi, I'm trying to use an eSim only (without inserting a physical sim) on my pixel 6 pro on AT&T, however I cannot get it to work. When I say not get it to work, I mean with eSim only there is no cell signal and no data signal. Physical sim works fine on both signal and cellular service. If there's another Us AT&T pixel 6 pro user who's using only the eSIM for service please respond and let me know whether or not eSim only works for you. Thanks.
Not an AT&T user here, am using a European carrier, just from anecdotal perspective: I also use eSim only and never had an issue on my P6 Pro. So it appears to be something carrier related.
I remember that I had to activate my eSim, maybe you also have to do this? Did you try out the eSim/your contract before using this phone?

Yes, I tried 3 times with the help of AT&T and we couldn't get it to work. I'm going to return the device for a new replacement to see if that fixes this issue. Thanks for replying.

Before going through the hassle of returning the device for a potential fault - do you have a family member or friend, whose simcard/esim you could try out? That way you can find out if your phone truly has a defect or if its your contract/the specific esim. Of course you can always let them replace your device, but that will take a couple days, maybe there are faster ways to narrow the problem down.

i tried again today at another AT&T corp store and walked out of the store with it working as expected (wait till the end). the person helping did additional research on my issue and discovered the P6P shipped to me "was not activated" with the inserted physical sim (which i removed when i received the device). apparently, AT&T will park (or associate) a new device with a specific number when shipping to you vs. walking in to buy a device on an existing line. nonetheless, i'm going to return the phone because the data connection isn't working consistently; data is on and then after i go to website, data turns off. i'm probably going to send it back to AT&T next week.
Finally got the phone working, but will get an unlocked version later; this one is still going back to ATT.
I'm using an ESIM on AT&t and even originally got the phone My plan was to have a physical TracFone SIM card and my AT&t esim which is exactly what I had on my Pixel 5 and it worked great. Both SIM cards work great... when the other ones not active or inserted. It is impossible to use with both SIM cards like I did on my Pixel 5. Constant signal loss and the majority of the time. No signal at all. But as soon as I deactivate or remove a SIM card it starts working perfect.
I had a problem with provisioning eSim on my TMobile, well technically its sprint still, says tmobile esim but I am on sprint billing. Anyways, you need to maybe try to do it on another WiFi access point or something. I had issues with mine activating over Viasat2 satellite internet. I live in that area, its either LTE or satellite for internet. Had to tether to my work verizon phone to activate it on sprint/tmobile lol. If the connectivity to the esim server is not great, you'll split hairs until it is.

Exactly the same issue/behavior I had with my AT&T P6P on the AT&T network so I returned mine today. I'm contemplating a Fi version to see if it works for my use case.
