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....

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.
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.
Hey all - long story short, my upload speeds today topped out at .13MB/s, so in desperation I called Verizon, who did some resetting on their end and talked me into resetting my wifi/mobile/bluetooth, which is in settings/system/reset options.
Since then, I've had no 4G and nothing has brought it back. Just did a factory reset and STILL nothing!!
Interestingly, when I open up my APNs, there's only the Verizon one, but it's never selected - even if I select it, still no LTE, and after a reboot it's unselected again. Also with this phone seems I can't edit or add APNs.
I am *absolutely* out of options - really figured the factory reset would take care of it!! I would be most grateful for any help you can give! Thanks in advance - can't tell you how much I appreciate it.
So fun story - on a whim I put the SIM of another 4G phone in, and works like a CHARM. So somehow resetting the wifi/mobile/bluetooth fried the SIM! I think I got one for free at the Verizon store last time this happened, so I'll head there first thing tomorrow!

So you put the SIM in another phone and it worked fine? I am pretty sure you just proved the SIM is fine and the problem is in the device, or it's configuration...
I have been through a dozen phone on one SIM, never had a SIM fail and I have only replaced it when changing carriers. Odd that this happened to you, and happened at least once before...
Nope, I put another phone's SIM into my phone

But you put your original SIM into another phone and it worked fine in another device? Or am I misunderstanding?
I am not trying to argue here, just understand...
No, I never did - I didn't try my SIM in another phones, but I did take the SIM out of my girlfriend's phone and put it into mine, which then immediately got a 4G signal, so I knew the SIM was the issue. Ran to the Verizon store for a new one, and the guy there said "whoa, that's a really old SIM" and I had to remind him what a SIM cutter was - I've had it a while
Hi guys,
My Samsung Note 10+ stopped making receiving calls about two weeks ago.
I have no option for VoLTE if that was the case; I updated my firmware to the last available (Android 12). I called customer service, and they did their "magic" with my IMEI and ID e t. c. I also went to their office, and they said they couldn't help me, but they have customers with the same issues with non-att phones.
Any solutions?
Thank you!
It's whitelisted.
*#*#4636#*#*, device info, enable VoLTE provisioned.

Thank you for your reply.
VoLTE provisioned is inactive.
Please, see the screenshot attached.
How can I activate it?
Not sure, but that's the problem.
Did you get a new sim card for it?
I got it a year and half ago. I will replace it today just in case.

The sim card needs to be configured for 4 VoLTE.
My N10+ was already running it, nothing happened after the switch.
Just got a new Sim. Nothing changed.
Still can't make and revcieve calls.

Was this originally an ATT phone?
No, originally Samsung US version, unlocked.
I have a N975U1 and a new N975U. These are both 4G only variants, no 5G*.
The N976U however is whitelisted by AT&T and should work.
I haven't fully configured the unlocked variant so after reading this thread I was wondering what it do. It hasn't been booted since the switch.
Slammed it the sim card and booted; it's working the same as it's sister.
Try clearing the system cache.
Network reset.
Reset on AT&T's side.
*5G Versions: SM-N976F (Global); SM-N976U (USA); SM-N976N (South Korea)
Thank you. My version is the US version. All those things are done. I think I will change the carrier. ATT is just doing nothing.

Something is misconfigured.
It may be the new sim card or ithe sim card may be damaged; install a new one yourself and handle it like a stick of ram, it's ESD sensitive.
Talk to Advance tech support at AT&T, get someone that knows what they're doing... may take a few tries.
Also clear the data in the sim toolkit app in addition to what I already suggested.
Try a hard reboot as well.
Access point names settings should be this:

I can't add NXTGENPHONE or ENHANCEDPHONE. It disappears right after saving.
There are many people with the same issue on the ATT forum. Many of them spent days talking to the support team; I tried it four times already and went to their office twice. Nothing helps, unfortunately.

I think the problem is the sim card.
On my unlocked new N10+ variant all I did to set it up was slam in the sim card from my other AT&T N10+. I didn't touch any settings on it.

After reading all of this, the only thing I have seen in regards to ATT not making calls is with WIFI calling if it does not have the carrier bloat.
You may have fun trying to find the user data file for ATT to flash for N976U.
If you could, load the carrier bloat U package and see if it resolves the issue.
The only other thing I have seen is when ATT deems a phone incompatible, they just suspend the SIM card and make it inactive. If the phone is whitelisted it shouldn't do this.
The best thing would be to go with someone like T-Mobile who won't mess with your SIM etc.

I did. I found it here. I tried different firmware. Nothing helps. I already ordered 22 Ultra. I didn't want to upgrade now, but I can trade in my old galaxy. In this case, it's acceptable for me.
So the weirdest thing...got my fold 4 early (Friday the 19th) through tmobile. Inserted my sim card and the second it detected mobile data it went into bootloop. I tried all the troubleshooting
Wiping cache
Wiping data
Physical sim
eSim
But in all my years messing with tech, I've never had a new phone out of the box do this. It's my first Fold, but not foldable...so this is especially disappointing. It works totally fine on wifi tho. Other than that, I've honestly been so impressed with this phone!
Has anyone EVER had a phone do that...especially NIB?!
Can you add your number to an e-sim?
Be prepared though, if it does the same you need to get a new sim card from TMO!
nvm, see you tried e-sim.
Maybe flashing the newest firmware?

Nah, not a thing. Besides tmobile just followed samsungs lead when they started shipping phones early.
UPDATE:
Got a new one, all is well. Definitely didn't give me the most confidence tho. It reminded me of the days when you'd mess up and flash a bad rom and go into bootloop.
