Several days ago, my Verizon Galaxy Nexus began showing an "R" in the signal area, and "Roaming" in the pulldown. Sure enough, it shows that I'm roaming in the about phone information.
The strange thing is that I'm still getting 4G speeds, but my phone is no longer seeing 3G at all, and any time I make a phone call it goes from "R" to 4G.
I cannot dial any Verizon short codes as it tells me they are not valid.
I was on Liquid ROM with 4.0.4 radios when I noticed the issue, and switched to the 4.0.2 radios but the issue persists. I'm currently running CM9 and can't seem to fix it.
Verizon tech support was clueless too. I've verified with my wife's Galaxy Nexus that this isn't a specific issue with our tower, and my sim works great in her phone without issues.
Anyone seen this before?
What happens if you return to stock?
I'm doing that now
Flashed back to stock 4.0.2, same issue persists.
Anyone else have any suggestions?
I am having the same issue, did you find a resolution?
Verizon GNEX
Rom: ParanoidAndroid 1.4
Kernel: Lean Kernel 3.10.0
I have the same problem, but mine maybe a bit different.
I am stuck on "R" here, but I was roaming for 2 weeks in Canada. I am a crack flasher and I flashed JellyBean while in Canada so I am thinking I am provisioned for roaming there? I am downloading a new rom to flash here back in the USA on Verizon, hoping to fix the problem. I cannot access my dialer in JellyBean after I *228, so I cannot hit 1 to provision.
SoI will do a SuperWipe and flash will hopefully do the trick. If anyone figures out what to do please update
I ended up having to do an exchange on mine :-(
damn, that is gonna be lame if that is the case. I bought mine at BestBuy, so I have to do their Rapid Exchange program. Glad I purchased the warranty while I worked there

Shouldn't really matter where you bought it. It's still under the manufacturers warranty so Verizon should take care of it unless I'm mistaken.

Verizon will take care of it if it is still under the manufactures warranty, just don't tell them where you bought it (they won't ask). I got mine from Wire Fly, and had to get it replaced due to faulty hardware, they sent it no questions asked.
thanks for the info guys!
Wanted to let you know my problem did indeed go away after I reflashed Slim Bean Alpha 4 here in the USA. I was roaming when I flashed JB, so I guess it picked up their provisions.
did you turn it off, pull the sim card.. wait 1min, then put the sim back in and start it up
Zep, I tried everything originally to make this thing work correctly. nothing helped every time to phone booted it went straight to R and never moved!
HOWEVER I do believe I have found the culprit!!! So everything worked beautifully all yesterday, no problems at all. This morning I decided that I would change the T-CDMA 64 on the bottom back to Verizon Wireless, well guess what. The second I added the "eri.xml" file to /data and reboot, I STARTED ROAMING!!!!
I went to root explorer and deleted the /data/eri.xml file and rebooted! VIOLA I have 4G back and it's not switching over!! So something is causing that eri.xml file to freak my phone and most likely others phones out!

Glad that worked for you. I tried everything including a complete wipe and mine was still roaming even after reflashing the stock ROM.
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.
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.
Has anyone used the SGH-I257M on US AT&T?
As I understand, it has the bands for multiple networks. The reason for asking is AT&T is dragging their feet.
Info I got from AT&T was that it has enough roll outs for Christmas and are not going to bring out the S4 Mini until January. My contract is up, S3 & S4 are too big for a pocket, I ditched my S3, I'm using an S2 clocked at 1.7 and gutted, nice phone, but time for a new toy to play with. I'm tired of waiting on the 'Mini', but flashable US Basebands will be unavailable for some time so I'm hoping someone has done this. More specifically meaning the 'non branded' SGH i257M and a functional LTE band 17. TIA

If you get an unlocked SGH-I257M from Canada it will work for AT&T with LTE. I got one as an early Christmas gift for my girlfriend and it works no problem. I just put her 4G microSIM from her old phone (Pantech Burst) and set it up. The only thing I had to do was add the APN for AT&T 4G. Also, I believe it was the ChatON app that would not work in the US but it wasn't important.
EDIT: Also, a question I was thinking of as well is, if when the AT&T version comes out (or the firmware at least) could the AT&T I257 firmware be flashed on an I257M? That would minimize any issues from the phone's software..

I appreciate the reply. That is good to know. Yeah, ChatON is of no interest. As for flashing, There are multiple reports that the 9195 ROM flashes OK on the M's, 9195 also adds the FM radio that is not given functionality in the M's but restored with the 9195 OS so I would assume the AT&T version should be no problem provided AT&T isn't pulling another non standard hardware version as they have in the past with some phones. (FCC filings don't indicate that) AT&T seems to have developed a phobia in recent years about their phones being retrofitted with new OS's. Also likely they are waiting for 4.3 or a Knox implementation in the deluded belief that it is secure. Thanks again for the heads up on function, looks like the price from Canada isn't too bad right now.

Hi. Thank you for sharing this. I actually just bought a Canadian i257M as well and now I'm waiting for it to get shipped to me. Question; do the samsung media apps work while in the US? For example, media hub, video hub and music hub? I ask because i used to own a GS4 from att and I purchased a lot of media on those apps and would like to continue using them if possible on the GS4 mini if possible.
Much appreciated!

You may have some disappointment, Samsung has switched to 'Samsung Hub' on the new phones, replacing the older Media hubs and interoperability suffers a lot. T-Mobile offers a Media Hub for their new phones, AT&T may as well since the Sammy app's leave so much behind. It's going to be a wait and see I suspect. With luck AT&T will have Media Hub apps instead of the newer Samsung replacements and all you will have to do is wait. It seems quite a few people have money tied up in the old system and that may keep it alive.
But other than that, all you need to get on line is write your carrier APN. The phone is turn-key as it is. I just got an 'M' and after gutting the OS, dropping in an APN and editing the Build Prop a little (not needed) it works great on US AT&T.
There are more and more of the i257M's turning up recently in the States and hopefully someone will be able to clarify the Media Hub issue more for you better than this.
Where are you guys getting unlocked 257Ms? I can't find anything on ebay and the internet suggests canadagsm may not be reputable.
Hi...wondering if you can help given you are on AT&T 4G LTE. My i257M arrived today from canadagsm and it appears rooted. Surprise, but maybe good. BTW...canadagsm handled this order ok, not great and not responsive, but they did deliver. Anyway so far so good, but I am also on AT&T 4G LTE and wondering how to edit the APN? Why? Right now I am only getting H+ connectivity. So wondering if there is a way to do this voa the hardware or only via software? Also, can you post the Build Prop? Lastly, due to rooted phones being disallowed on my company network I can only use a stock ROM.
Lastly, as I write this I ended up going into the boot ROM and which is not CWM and for the last 30 minutes and selecting install the volume up, the screen shows DOWNLOADING, DO NOT TURN OFF TARGET!! However, I am not aware I am downloading anything and seeing this screen is a bit scary. I may mess with this a little more by the time anyone gets a chance to respond, so we will see.
Thanks in advance, malloy0

I just made a thread abouu this. Just picked up a i257m and on every kind of combination of rom I'm stuck at only h+. I spent a few hours on the phone with cs to figure out why after googling a few other cases similar to ours. Turns out att doesn't support unlocked phones so the account isn't setup to push lte. What others have done, and what I'm going to try to do tomorrow is pop the sim into an att phone thss can do LTE and set it up and switch back and it should follow.
Att were assholes and wouldn't setup a device on my sim temporarily to prove to me LTE worked on my account. We popped my dim into a display g2 that was getting LTE, and got only h+. So I told him to pop the display sim in mine to see if I can get LTE, it only triggered the LTE option in the settings but never popped up saying it was getting any.. Hmm
Edit: got lte working with a new sim! All works perfect on att!

Where are you guys getting unlocked 257Ms? I can't find anything on ebay and the internet suggests canadagsm may not be reputable.

Just wanted to throw in an update, I took the risk and ordered a 257M from CanadaGSM. Minor hiccup with the webpage didn't forward my address to their credit card processor, but they sent me an e-mail and a paypal invoice, and shipped out the phone the same day I paid. Quick customer service response time via e-mail, too (as in within a few minutes). It works great on Straight Talk, but I don't live in an LTE area so I can't test that till this weekend.
It rooted easily, and now it's running PAC.
Edited to add some information.

Good news for CanadaGSM...I too was leery, but after a few emails and phone calls they stepped it up big time. For now I have retired the S5 mini in favor of a Nokia Lumia 520 for $65!! Woo-eeee!! It's a super smooth phone. Apps are a little limited, but still have found everything I need except "stay awake" with charging. as for the S4 mini on LTE? No luck at all and expect one of two things...1) it's a locked Rogers phone and I am on AT&T, thus they will not allow LTE or the phone is not truly LTE capable.

Can you post some detail about the rooting procedure that you used? I have not yet seen a complete procedure for the SGH-I257M.

Use the 9195 root method and 9195 roms, same phone just different lte bands.
What I did was use Odin to flash recovery then flashed the root kit then used the unlock app from the play store to be able to run att. Then I flashed my liquidsmooth and havent looked back!
I used Odin to flash philz touch recovery, then flashed the PAC nightly. Only issues so far are ROM related, like launcher preference and battery drain
Sent from my GT-I9195 using xda app-developers app
Hi, i've been using my S4 since May of this year.. It was originally bought in Canada (rogers) and I have been using it on Tmobile in Las Vegas since May... There were no problems until the other day. Out of now where it stopped working. It does not read sim. I went to the Tmobile store and got a replacement sim but still no luck. The sim works in another phone just fine...
Does anyone why it won't connect to the network? There was an update on my phone about a week ago and i did update it to the latest software.
Very frustrating. hope someone can help.
thanks

Do you use a custom rom???? I had a problem like that a few days ago. I had to flash a different "radio" MK2 and then my phone started working fine again.
