SYMPTOM: can't see any mobile networks
BACKGROUND: I've been using htc one x for a month now. Initially on three, but their signal was unusable at home, so sim-unlocked and switched a couple of weeks ago to giffgaff ( a virtual network on top of the UK o2 network).
All has been fine, until today. I sent a few texts & calls in the morning, and mobile data was working. Since then, I can't see any mobile network.
wifi is fine.
Search Networks pops up "Error while searching for networks" and finds none.
No software changes of any sort since last successful call. No changes at all today, at least until I tried to diagnose the problem.
Running stock rom, with the WW update of a couple of weeks ago (1.28.771.9.CL56522 release-keys) -- neither S-OFF nor unlocked bootloader.
Nothing obvious to me in the normal or radio logcat logs.
The only thing I did after the last successful call was to run sensorly to try and map a trip. I've used this before without any problems. It got no connection but I thought nothing of that. I've since uninstalled it just in case it could somehow be interfering with the radio.
THINGS I'VE TRIED:
No, the airplane mode isn't on, and mobile is. I've toggled airplane from settings and power switch, many times
recreated the APN
checked other phones - yes there are a number of networks visible
tried the original o2 sim - same problem
safe mode
cold boot
reboot, reboot, reboot
obviously I haven't pulled the battery...
turned off wifi, in case it was somehow interfering
HTC diagnostic tool
factory reset
confirmed imei is not blocked
Any ideas? Bearing in mind that I'm looking for something which can happen spontaneously.
Interestingly, while writing this I've just noticed that Baseband version shows as Unknown. That worries me - is it possible that my radio partition has spontaneously corrupted itself?
I did speak to 02 support - they said to take it into a shop for warranty repair. I don't want to try a custom ROM just yet -- not when I might have to use the warranty. But is there any way to force it to reinstall the stock rom (preferably not involving windows)?
I have the same problem as well and flashing custom roms did not solve it for me. But for me even the IMEI number is shown as UNKNOWN...I haven't done anything special to get this issue, one day when I woke up the phone could not connect to any network.
I have tried a lot of different methods but with no success. I don't think we can do anything about the baseband without S-OFF.
If a hard reset fails, then it's time to think about returning the unit. Either get a refund or get it replaced.
This may be irrelevant; but I've had this happen to me on my GNexus. I solved it by going back to stock and it just fixed itself overnight.....
my HTC One X did the same after about 2 weeks. Gave it back to supplier, waiting my replacement.
Even tested with a different SIM card, did a hard reset. Problem stayed the same.
Im curious did any of you find a resolution to this? it happened to me a while ago but yet to fing a solution. HTC refuse to fix under warranty because it is unlocked.. i am currently waiting for the next official update to see if that fixes anything but the way things are looking that could be a while..

It sounds like a fault, probably the radio chip has just stopped working, no software is going to repair that. If it was a software problem, there would be hundreds or thousands of people all having the same issue.

Hey guys it's been a while and I have long since jumped the smartphone boat due to economic reasons but I still held onto my first generation droid incredible to use as an MP3 player in my car & as a camera since it does take pretty decent pictures for a cell phone. At least it's cheaper than buying a brand new ipod touch for sure.
This morning I remembered after hooking it up to my computer that I could turn off the Verizon CD image mount through one of the hidden menus accessed by the dial pad but I couldn't remember which one it was at the time so I tired at first the ##778 and flipped through the sections to find what I was looking for and then things got interesting.
Under my security section I found that the HDR AN AUTH Password and PPP PASSWORD had been set to something that looks like leet speak to me along with some random symbols "UBINuHDX:n'!" along with a few extra characters that I cannot reproduce on my computer at this time. In my mind I read this as "u been hacked" which doesn't make any sense as the phone is on stock firmware with security turned on and it's on the latest firmware.
Here are the detailed software specs for my phone.
Android version: 2.3.4
Baseband: 2.15.10.07.07
Build number: 4.08.605.2 CL185897 release-keys
Has been rooted in the past?: Yes with unrevoked & S-OFF
Current status: Unrooted with stock firmware and S-ON
The phone has been on stock firmware with S-ON for 7 months now and I just now found this.
Has anyone else notice this recently or has any clue as to what happened and what I need to do to fix the phone so that its not hacked like this? I know I can factory reset but how will I get past the activation screen to continue using it as an MP3 player for my car?
Hope someone can help me but for now I'm isolating the phone off my wireless and changing all my passwords once more since this thing has been directly connected to my computer several times and who knows how long this has been like this.
This is normal. The password is encrypted, making it look like weird characters. Only verizon has the key to decrypt it, and was issued by verizion ota. The only people who have access to changing this info is verizion, and anyone who physicly has access to the phone.
From time to time I cannot connect to mobile data, even though 3G shows above the signal triangle. A few solutions that randomly work are to toggle the radio from LTE/CDMA to CDMA only (and then back to LTE), toggle in and out of airplane mode, and the last resort of rebooting. The only method that works consistently is rebooting. Happened again today, and I noticed a few oddities on the phone status page in settings:
- Both IMEI and MEID were shown as "unknown"
- Phone number was visible
- Mobile status shows "connected"
- IP addresses (both IPV4/IPV6) were assigned
Prior to this (for the past 108 or so hours of uptime) all was fine, but in the midst of playing Words with Friends the signal bars grayed out and would not resume the connection. After several trials of my "solutions", I had to reboot. Sure enough, after reboot all was well again, and the IMEI and MEID were again displayed correctly in the phone status page.
As my signature shows, I am stock unrooted. While I have seen that a few individuals somehow wiped out their efs partition during a flash, that doesn't seem to be the case here since all of my info came back upon reboot.
Thoughts?

Since you're completely stock, try exchanging for a referb with Verizon?
Will the next nexus have a longer screen?
I found that reseating the SIM card fixed my triangle (Roaming) issue. May be worth a shot.
I had this same issue. Sudden loss of service. IMEI: unknwon, Phone Number: unknown, etc...
I brought it to VZW to try a new sim. No go. They told be to call Samsung.
They verified that I actually had tried the idiot proof stuff, and confirmed its dead. Still under 1 year manufacturer's warranty. They're paying to mail it back and say they'll repair it, and send it back to me. Here's hoping they don't care that I've been flashing it like crazy for the past 5 months.

Hard to say our problems are related. I am stock unrooted, and as stated in the OP only my IMEI and MEID were unknown. Also came back on reboot. Chances are you killed your efs partition during one of your flashing sessions.

In the future, if anyones IMEI/MEID is perm-disabled due to whatever reason... my thread found here(Post #2) has info on repairing the Gnex MEID/ESN/IMEI.
This has happened to me recently. I've been flashing *safely* since the G1. Since Jelly Bean flasshing removed my network access. I went through a warranty repair and upon unlocking same problem. If my MEID or ESN is corrupt, I have not figured out how to repair it using Prime's instructions. That's a new world to me.

Autoprime, I did find that thread in my frenzied search to fix my phone. I downloaded the tool in post #2 but was confused how to get my phone connected as a COM port, or converserly, it would not recognize it when I changed the setting to USB. Do I need to put my phone in a particular mode, before that utility will recognize it? Do I have to go through the setup in Post #1 (ETS) prior to using the IMIE writing utility? Thanks.

as u said in last sentence... you will have to go thru post 1 steps(only some of them!) to connect to meid tool.
since you guys are on a verizon gnex.. you would need to flash a Sprint rom in order to set the phone into diag mode. i believe most vzw roms have these options left out.. at least stock did.
2 things are required for a successful Ets Diag connection...
1. setting diag mode... this is the *#*#DIAG#*#* menu
2. setting Ets Channel mode to "USB" . This is done in the *#*#DATA#*#* > More > Ets Channel settings.
It MAY be possible to stick with the Verizon rom and use the Sprint Diagnostics App: http://forum.xda-developers.com/showthread.php?t=1774503
not sure if it works with VZW roms tho(im a sprint user).
The VIA Ets tool is the equivalent to messing with QPST/QXDM on Qualcomm phones. Just like Qualcomm phones have to be put into diag mode first before connecting to QPST, the Galaxy Nexus has to be set in the right mode as well.

Thanks very much for laying that out. Is this something that "just happens"? It seems like (over several months) I flashed 50 - 60 times, radio a few times, changed from CWM to TWRP with no problems and then in the middle of the day, I just lose signal.
Could it be a hardware issue? I read somewhere that a modem in a phone got fried and caused the same thing.

i mean.. in my experience it comes with messing with the phone.. the EFS etc. could be from a bad flash.. but yes it could be hardware... or theres even a small chance its just random. youd have to look at the factors leading up to the issue for the best guess.
overall tho.. outside of messing with the efs/NV.. its kinda weird for it just just to happen.. id consider that very rare.
UPDATE: sent back to Samsung. They replace the main board under warranty. Works like a charm now.

Missing MEID/IMEI no service but internet is working.
I've been searching high and low and have came across various forums that are related to my problem but I'm still not sure if its the problem I have
or what to do exactly. I have a Samsung Galaxy Nexus with VZW, rooted, running a custom ROM (CM10), Android version 4.1.2 JZO54K. My
service got disconnected and when I paid to get it reconnected I get an empty signal triangle and sometimes an R above it (roaming). My internet
works oddly enough but I'm unable to receive/make calls or text messages. My status reflects; Network: searching for service; Service state: out of
service; Mobile network state: disconnected; MEID: unknown; IMEI: unknown. Before my phone was disconnected it was working fine, please
help!!!
If you did some backups time to time and if you have backup of data folder, inside of data folder you should have folder radio. Inside the radio folder should have data.bin file and data.md5. In my case they was original data files of my phone and after their copy to factory folder ot restore my IMEI.
I hope that helps.

Hoping someone can provide some direction. First and foremost I am not a HTC savvy so although there are a few threads here about the same issue none of them relate to me as I have not rooted the phone nor flashed to custom ROMs or anything to that nature. I am simple user of the phone... Now.. to the topic.. so I bought this phone for my brother in law last year as a birthday present, and at the time I had a working phone so I didnt put my mind too much to it.. but I did liked the phone very much. Two months ago, I decided to purchase one of these, so I bougtht an HTC ONE X Phone S720e Android 32GB 8MP 3G WiFi GPS Bluetooth Unlocked White. I don´t recall what versión of Android it carried at the time but looking at the specs it should had come with Android 4.0.3. After loading it up, transfering my files on to it and loading some basic apps, whatsapp, email, Skype... it off coursed asked for a software update two times which I went ahead and did. The last one it installed added Android 4.2.2 and HTC Sense 5. It was working fine, layout changed considerably... now after doing another of the updates to applications and software, specifically the transfer files update it suddenly quit recognizing data services completely. I though it might be something with the micro sim, so I tried testing a couple of others, it didnt make a difference so I decided to back up my contacts and information I had on the phone and did a Factory reset. It wipped it clean but issue remains the sames, it is unable to even recognize the sim card is missing and when I go into settings I see the message Disconnected because service is unavailable.
Reading online, saw a few folks stating that this situation was related to software updates.. so I was wondering if I could get some help on how to get this fixed. Not sure what to do, downgrade to 4.0.3 or how could I get it resolved so appreciate some direction here.
If you go to settings - about - phone identity, does it still shows the imei ? Seen many people here having their imei gone from their phone and becomes an iPod since we can't write it back. Tho you are on stock, so better send it for repair.

It shows up as unknown actually... is this a software related issue then? Im concerned about the other phone going through the same situation... should no updates be installed to it then? That makes it fairly useless and might prefer to send it back and try to get a refund instead.
same problem for me, still wait for fix

Hi,
Just something that worries me a lot atm and wanted to ask/alert people about. Probably 'a thing' that everybody knows about (?) in which case .. .well.. carry on, nothing to see here
I ordered a replacement motherboard for my LG G4 (H815) on ebay and the board I got does not seem to have come with the Stock ROM on it although it does appear at first to be stock.
When going through the pre-installed Apps I noticed that there was something odd though : it comes pre-installed with SuperSU (which starts automatically at boot). Even worse : I can't remove that SuperSU either, only Disable it.
When I tried to Unlock the bootloader at LG's website and replace the ROM (something I had done before so I know the procedure) I was told that the IMEI and DeviceID do not match. Replacing the ROM seems to not be an option even though it probably was rooted before to install the current ROM. I haven't tried to flash it with LG Flash yet ... so maybe that'll be the way out.
The more I started thinking about it the more nefarious this seems to me : a replacement motherboard with a locked bootloader that can't be unlocked (the ROM on it is Android 5.1 btw, not 6) which starts a SuperSU service at boot that most people probably wouldn't even notice and which has access to :
- Google Play billing service
- Retrieve running apps
- Run at Startup
- Prevent Phone from sleeping
That service could turn that phone into a zombi and considering that more smartphones than this one are probably in the same state things could get ugly.
What's worse, although I did disable it, there really is no way of really knowing that the smartphone is indeed 'safe'. I'm surely not going to use it for Home Banking atm! But even email or adding a Google account , or using facebook, etc already are things you probably shouldnt do when somebody else may have root on your smartphone..
kind regards,
Benny

Wow that's unfortunate
Maybe try @steadfasterX's SALT utility and see what info it gives you. Also, I assume the IMEI is from the software and not the back of your phone (e.g. the one from your previous motherboard)

hi, Thanks, I'll have a look at Salt Utility. Got the IMEI from the OS, not the sticker. It's actually not just the mobo that I replaced. This G4 is 'lego-ed" togheter from parts sourced all over the place so do not have the original housing I have a second, unlocked G4. This one was supposed to be my backup. Maybe the unlock simply fails because somebody else already unlocked it before - not sure if they could relock it afterwards , maybe they used Salt and didn't unlock...
Thanks for the response.
Edit : Come think of it, maybe the Device ID is not only dependant on the Motherboard but calculated from information gathered from other parts in the system as well like the screen , cameras, sim card reader ... who knows :-/ Might not be able to unlock any LG when any of those unknown parts is replaced.

. As long as you talk about the device ID displayed in fastboot it is coming from your mainboard and can't be changed. if you talk about the Android device ID it's generated by the ROM and that one can be changed easily

I'd be interested to know whether the IMEI and device model from SALT match the values displayed in the OS
