I have just got a phone from eBay, and after a while it comes up with 'no service'. I can use the SIM ok in my nokia, and have also tried with someone else's SIM in the TP2 with the same result 'no service'.
If I hard reset (back to stock Orange) the signal works well for a while (a few hours to a couple of days) before coming up with 'no service'.
It looks like original ROM (with SPL) and radio.
Has anyone else had any similar problems? Is this a hardware issue? I don't really want to flash another ROM/radio if not known solution as I want to give it back to seller and get my money back.
Anybody help or had experience of this?
Might be stolen ?
Have you rung orange to see if they've blocked it by any chance ?
Agreed, check the IMEI number with Orange, chances are it's been blocked for some reason.
Thanks, that was exactly the problem. Phone has been blocked. Orange (surprisingly) have unblocked it and told me not to buy phones from eBay.

Blimey
lol 'don't buy phones from Ebay
Good luck with your new phone dude
Know the problem....
I have the same problem, but now i know what its all about. I bought also the phone from a private person and they have probably blocked my phone's IMEI gonna call the phone company or something. But i wonder if they have blocked my phone howcome the phone gets connection with another sim card ( still cant call) I havent been able to call with one of the sim cards, but once I could message with the other sim that i get a connection to.
What did orange said to you man?
My 2 month old One X seems to have developed a problem today, with it's GSM/UMTS radio. Was working fine this morning in Dublin. Caught a ferr y back to the UK and it was still fine but by the time I got to my office in Chester, it was showing no service. I just put it down to a local issue with the Vodafone network. But, on the 200 hundred mile drive back to London, despite rebooting and trying to force it to re-register as GSM, WCDMA in GSM/WCDMA modes, I've still not managed to get anything other than No Signal. Clearly not a general Vodafone network problem as the UK news and internet sites would be all over it.
I got back home and tried the other Vodafone SIM that I use in my Galaxy Tab (screwing up the SIM slot in the Tab, in the process) but exactly the same problem. I've spoken to Vodafone and despite me trying the other SIM, they've just said it looks like your SIM isn't registering with the network, so we'll send another out. All good except I'm off on holiday tomorrow.
I'm wondering if the radio "chip" itself has gone AWOL and wondered if there is any way to diagnose that on the handset itself? Any ideas if that's possible or anything else I can try to diagnose the issue?
Failing that, I guess it needs to go back to HTC for repair/replacement. Anybody know how warranty repairs work and how long it's likely to take to resolve and anything I should do with the phone beforehand?
You need to try your sim in another phone to eliminate the sim card
If its the same in another phone its the sim if it works fine its the phone
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,
since a few days, I'm not able to access 3G/LTE anymore in Germany with European G4 H815. Bootloader is unlocked (so no warranty for me).
I already reflashed it with KDZ with CSE flash, also tried to enable/reflash LTE Bands described here:
http://forum.xda-developers.com/g4/general/guide-enabling-lte-bands-t3137818
2G/GSM/Edge is possible, not more. Forcing the network to use 3G only results in no connection to the network.
Tried also swapping SIM cards with my GFs smartphone, her SIM card can also only get GSM in my G4, my SIM card can easily get H+ on her smartphone.
May this be a defective modem, or maybe a software bug? I flashed Genisys Rom, now back to stock.
Help would be greatly appreciated! Any thoughts?
Kind regards
Have you tried erasing and then adding in a new APN? If it worked prior this would be a good starting place
Thanks for the answer! Yes, I tried any possible APN configuration.
On my wife's h815 I can't test this as access is denied, but your on genisys ROM so it may let you
Open the dialer and type
*#*#4636#*#*
Hey,
I tried it, but could not click Phone Info. Error message is:
This application does not work on this device.
When I first rooted the G4, I backuped all system partitions. Maybe I should try to revert them all? I already tried to restore MODEM, MODEMST1 and MODEMST2.
Or could this be dangerous?
Kind regards
Yeah same with my wife's phone, it's strange were locked out there..
Restoring those partitions shouldn't hurt anything but I'm not very familiar with this phone so can't attest to anything for sure and the wife is on holiday so I can't check her phone
When you went through apns, did you try to first erase them all completely? If not try that, then make a new one
Yeah, I've got only one APN. I also requested a new one by my provider via SMS.
I wonder if the modem itself is defective. Maybe it got fried by wireless charging, I'm using a chinese Qi-Sticker and replaced the original one.
Are you using wireless charging?
No, just a cheap dock, but as far as I know that won't fry the internals or interfere with the radio at all
The reason I keep asking if you fully erased all apns and start over is I had to do this with a 2013 motox when it switched to lollipop, for some reason all apns had to be erased and then readded to get lte/3g to work again, the phone was stuck on edge just like yours
Okay, I found out by chance today, that there is 3G/HSPA reception possible. I was standing outside 100m away from a cell tower, and had medium reception. Maybe there is a problem with the internal antenna?
Oh, and by the way, I can see LTE network here at home (but no HSPA), but don't have a LTE contract, so I can't connect to it.
Maybe next time, when you are next to a cell tower, you try it yourself?
I haven't found a solution.
LG refuses to repair to my G4 for free, but I buyed the phone at Amazon (De). I called the hotline, they cover the warranty for 2 years, so today I sent the phone in for repair.
I'll keep you updated if Amazon repairs it despite the bootloader being unlocked (I told them before).
Sorry I couldn't offer a technical solution for anyone with the same problem
This is what happened in the meantime:
I sent the phone to an Amazon Partner Service Center. They refused to repair it under warranty - Bootloader unlocked. They offered me to replace the motherboard with a new one - 283€ incl shipping
After that offer, I called Amazon that their partner would not repair the phone under warranty.
They then sent me a brand new G4 for free! After I already had received the new unit from Amazon, of course I had to send back the defective G4 (when it came 10 days later from the repair service).
My friend has exactly the same problem.
Bootloader is unlocked. Tried to go back to stock MM 20c firmware from Imperium v1 Rom, but that didn't work. Also no update to 20d is offered by LG. If i force to use 3G, the phone can't connect to the cell network. Only edge does work. APN looks also good. Furthermore i tried to flash a new/other modem, but that didn't work also :/
Does someone have any suggestions to fix this problem?
@t000x: Was unlocked bootloader and therefore no warranty no problem for amazon.de?
Hi hasenbolle,
try restoring the firmware first, before shipping it back:
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
Yes, Amazon gave me a new unit despite the bootloader being unlocked.
But first I had to send it to their partner service Center and wait a few days.
Good luck with that phone.
