So I recently flashed the CM10 M2 rom on my verizon GS3 and it worked good for a week. Now I can't get any service on the phone.(calls, internet, etc).
I flashed it back to bone stock using Odin and still didn't do the trick. I thought it might be the SIM card but I tested it with my old Droid Razr and it worked fine. Any solutions? I really want this phone functioning again. thank you
Kinda new to Samsung and Verizon but from what I read, u may have list your imei, you can look up tutorials on you tube on how to restore it if u backed it up, or how to install default ones. Happened to me and I had to do a factory reset and re root

wasn't sure on how to restore default imei. I did an unroot and re-root and still didnt work. still need help
still in need of help I noticed my IMEI was at 0 so went through a long process to restore it. Now I do have a number under "IMEI" but mobile network still isn't working. I'm currently running stock everything. please and thank you
Well if your like me, you now believe you have a $700 brick. Well I had t he same issue, and I'm rolling done the highway typing this post on my phone. Just fixed it today in fact. This is what I did to fix it. I have a vzw sgs3. Flash it to stock. Flash stock modem fw. Search the forum for restore imei guide tool. Follo those instructions and you'll download a file with a panda icon. after that, when it turns on you will still have no service. This is ok. Search the forums for SIM reprovision. One of the posts tells you to back up everthing including your internal sd. Do that if you want your stuff. Then it will tell you to dial *2767*8858#. (I know these are the wrong numbers but they are in the *xxxx*xxxx# format and it starts with *27.) This should do it.when it reboots it's like a factory reset. But it fixes it. Oh and I also had Verizon give me a new SIM. To 're cap... search Guide imei restore tool and SIM provision.hope this helps.

I would like to first thank you for your input. Although i had that panda icon program i used a different program to restore my imei as well as my eri. After doing that i thought i finally fixed it then realized im still missing some of the numbers under phone status such as MIN. PRL version and ICCID. does the sim reprovision fix this.
Thank you all who have gave me advice to fix this problem. I finally got it fixed and i can't be happier. After going through circles restoring my IMEI and PRL it still wasn't working. What did the trick was dialing *2767*3855# which did a factory reset. My mobile is working again!!!!!!!!!!!!!:highfive:
Hi,
I'm new to this forum.
I got a new Samsung Galaxy Nexus (unlocked GSM-i9250) mobile thruoug Google Store and got it to India.
I did an OTA upgrade from ICE Stock 4.0.4 to stock JB 4.1.1. My next upgrade to 4.1.2 failed, though detected by system failed.
So I used the phone for about 2 days and one day after charging, there was no radio service. WIFI works. Tried another SIM
and operator but in vain.
As all my efforts of factory reset, reboot etc failed, I thought of reflashing the latest images.
So I downloaded the latest images from Google site, unlocked the bootloader, followed different threads
and tried updating to 4.1.2. System now boots to 4.1.2 and WIFI works, but no GSM service still.
In the phone settings
Basebad version : unknown
Network : Unknown
IEMI : unknown
Service state : Out of service/Radio off (keeps toggling every 4-5 sec)
So I tried going back to 4.0.4 and system boots back to 4.0.4, but no GSM service
No idea what is happening. Two of us bought at the same time and got the same to India. For my friend, the OTA updates
to 4.1.1 and 4.1.2 went through fine.
I saw similar issues reported but not able to figure out how finally they solved it.
Any suggestions/help is appreciated.
Thanks in advance

I had a similar experience with my previous Nexus S device. The phone would start up perfectly fine but it wouldn't catch reception. I think I flashed the wrong radio.img file (there are a lot of Nexus S variants).
I would try the following steps:
- Flash CWM recovery
- Flash a custom ROM (you can use "Mounts and Storage" in CWM recovery to gain temporary access to your internal storage - you will need to do this to copy your ROM file there)
- If you like it, just stick to the custom ROM.
If you insist on going back to the stock ROM, there are threads here that guide you to go back to stock completely. Even if you go back to a previous ICS ROM (specific to your phone), you should start receiving OTA updates normally.
Best of luck!
Thanks for the reply.
I'm almost sure the radio image is fine. I downloaded the images from
Google Nexus developers site for "takju" for Galaxy Nexus "maguro" matching with my phone.
I flashed matching ROM and radio images from Google site. Tried both ICS 4.0.4 & JB 4.1.2
I'll try custom ROMs if nothing works out. I'm going to try this first time, so need to chk the threads first. This is my first Andriod phone and already ran into trouble after just 2 days of use, that too without any manual flashing. Only OTA happened before the issue.
Could the h/w have gone bad ?
In fastboot mode, the radio version is displayed correctly, but not after phone is up and running.
If the h/w has become faulty, I still expect the "Baseband version" in "About Phone" to be correct.
Is this assumption correct ? If it is s/w issue, I'm relived and I can try some custom image. So I'm hoping its only a s/w glitch.
Thanks a lot
you flashed the wrong rom on your phone and corrupted its efs partition. If you have a backup (why should you if you didn't even know that it was that to fail your phone's radio..) you could proceed and restore it. If you don't it's a big mess and you might have to go to a repair service.
Anyway you could still try and flash the original ROM for your phone and see if it fixes the problem. If not there are tools on the web (search the forums) that could try and restore your partition even if you don't have a backup.
If you succeed in restoring your phone don't EVER forget to backup you /efs partition
Thanks.
I tried flashing as the phone radio just stopped working after I charged the phone one day morning.
Let me follow your suggestions. I didn't know about efs partition. may be its messed up
What is puzzling me is, how can the factory images from google be wrong.

It's not the factory images to be wrong but the fact that if the /efs partition is really corrupted the stock images don't contain the info necessary to flash that partition as well.
In fact it may become corrupted after a wrong flashing but a new, correct, flash won't restore it. The only way back is the /efs backup.
What if you type *#06#? Does it show you an IMEI number or what?
*#06# shows "OK"

Between the blue line and the OK it should show the sixteen digit long IMEI number. the fact that it isn't shown simplifies the diagnosis. I'm 100% sure you've got your /efs partition corrupted.
Please do a forum search on how to restore it.

This eliminates so much un-wanted time waste/means no need to try various steps.
Can I get efs dump from another Galaxy nexus and flash it on mine after rooting ?
I'm under the impression that IEMI number etc should be in OTP and that can't get corrupted but efs may have some meta data regarding the same

No can do, the IMEI is a per device unique number.
Check this thread and do some forum search: http://forum.xda-developers.com/showthread.php?t=1689525
You're not the only one that lost the IMEI so chances are likely to you to resolve your issue!
If I copy the IMEI number from the box or my working phone, will it work ?
What I want to know is, is it only coming from EFS or if IMEI is changed will be there be some signature that will fail etc
I have used fastboot but not sure about rooting, so need to read that before trying Rooting
In India, Samsung won't repair my phone as I got it from US.
Another worry is, let IMEI number be wrong and let there be no network, but atleast "Baseband version : Unknown" shdn't come in the phone, correct ? Coud there be any issue with radio image partition itself ?

Mate - I too am from India, and I too got the exact same problem, and I too tried all you did - all this about a month back. I have reconciled myself to the fact that its a hardware issue. Since samsung centers in India won't do any repairs, I'm afraid we're both stuck with really expensive music players.
My sympathies.
Fixed by sending in for warranty
Just an update...I was having all of these symptoms...unknown IMEI, Baseband, etc...basically gave me an expensive media player for a few months while waiting for a fix on XDA. After no update I decided to call up Samsung and after talking to 3 different technicians, I was able to send it in. Just a note for anyone about to do the same, they will try very hard to blame it on the carrier/SIM card, so save yourself some trouble and just say you already went to the physical store of your carrier (calling isn't enough)and they couldn't get it working. Once you get past that, they will email you a printable 2-day UPS shipping label so you can ship it to them for free. It took 2 weeks from the time I called to having a working phone back in my hands.
This was their fix:
Problem found:
NO PCS SERVICE
Solution:
REPLACED PBA
After a quick search I found that the PBA is the motherboard, so it's definitely a hardware issue. Hope you guys are still under warranty because I've heard this is ~$200 to fix otherwise.
Good luck.
My Nexus 5 suddenly has no signal today, but WIFI is working (my nexus tab has a cell signal so its not a network issue.)
was using CM12.1 (5.02) tried the following:
reboot (many times)
did a factory reset/wipe
flashed a new CM rom (Euphoria 1.1)
hit *#*#4636#*#* and checked the radio is on
popped the back and cleaned the antenna contacts
None of the above worked, now I'm wondering what to do next...?
Any suggestions would be gratefully appreciated.

Do you have an IMEI (Settings>About phone>Status)?
IMEI is present
Airplane mode is off :silly:
Sim card is fine, I tested it in my old i9300
I guess I will go factory image later today and see about that.
Thx so far.
Well it appears the fone is dead...
I restored a factory image (4.4.0)
Still no cell signal.
Going through the updates 4.4.2 > 4.4.3 etc, but I doubt its going to make a difference.
Bought in 2013... I hope (but doubt) I can get it fixed under warranty

It's not enough to restore factory image. Try to flash completely stock. http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
Sorry for my wording, I went completely back to stock and unfortunately it did not fix the issue.
It is still covered under warranty and with the stock restore its is now ready to be sent back.
Back to the old i9300 for now!

After you flash back to stock, what steps are you taking when setting up the phone again - are you restoring app backups and stuff? I had this same problem, when I restored as new and did not use the google backups, my radio/mobile network returned.
I dint bother setting up my accounts or restoring backups as I expected it not to work.
I did not want to bring unforeseen things into the mix.
Restored 4.4, made sure it was unrooted and the tamper counter was reset. locked the bootloader.
Then skipped the google account part, only added wifi password. Then went through the system updates.

Mine did the same thing (worked for phone/texts but not mobile data), and in my searching there seems to be a related fix having to do with APN settings, but those are only accessible in settings, under mobile network, if you have a specific carrier.
Try searching around here for "APN XML" or "APN update" and you'll find steps on how to check/fix. Hope that helps.
I updated my Oneplus One manually to the newest Version of CM12s. While flashing it, my Recovery (TWRP) chrashed. So to be sure I installed my freshly performed Nandroid Backup. But nothing helped. I couldnt connect with the Wifi, no SIM Cards were found, no Bluetooth Connectivity and it had Random Reboots. So i decided to flash back to Stock CM11s (the first ever released). But the Problems were the same afterwards. I flashed the Stock image via ADB and, after I found out nothing changed, via the Oneplus One Toolkit, but the Problems were still there. I also made a video on Youtube to show what happens and i hope that i can repair it and must not send it back to repair, because a repair would cost me up to 300€. So pls tell me a way to fix this Problem, because I really like this Phone:crying::crying::crying:

Ok found your vid, I see you have flashed the stock image files via ADB, have you done a full factory reset (wiping data) from the phone/TWRP? Its a bit worrying that flashing the stock image files didnt sort the issue. As it seems to be WiFi on/off that causes the reboot it would make me think it was to modem/radio but this should have been written again when you flashed the stock images.
@AxelWexel can you check in your Settings>About phone menu if your IMEI number is showing? Just in case your EFS has become corrupted. It definitely sounds fixable as if something has corrupted and needs wiped fresh.

Thx for the Links and i tried to watch on my phone and there is no imei number. I also did a full wipe after i found the issues. I also tried it via the Toolbox to flash the stock rom back but it hadnt change anything. But I will look the links you postet and reply if anything has changed. But now thx again:good:
P.S: I renamed the Video to "Oneplus One not working (23.06.2015)" to find it more easily
Edit 1: The Second Link with fixing corrupt partitions via adb wont work for me because i dont have root but my bootloader is unlocked. so i cant find the root acsess for adb in the developer options
Edit 2: I installed color os like the link said, done everything it said, but still no wifi, bluetooth and no sim card detection:crying:. Luckily the random reboot stopped Could you again help me further more because it seemed to help
Edit 3: I went back to cm11s, because in color os when i turned the phone off it turned on again, the connectivity was not there. After the install it became worse with the random reboots. I think i must send it to repair and pay 300€:crying::crying::crying::crying:
>> Partial solution was found; still looking for the root of the problem. <<
I recently decided to take the plunge and root my OnePlus One and install sultanXDA's CM 13 ROM on it. It was all going well until I booted up into the ROM and discovered that I couldn't get any mobile data. Everything else was working, calling, texting, wifi, but mobile data seemed to refuse to work. Since I initially flashed sultan's ROM with TWRP 3.0.0, I suspected it was a problem with my modem. Though unable to install TWRP 2.8.6.0 to re-flash everything, I did still flash a new modem via ADB. This didn't help.
I have tried many things to fix this. I rebooted/reflashed. I flashed different ROMs. I tried flashing on TWRP 2.8.6.1, though I believe that one has the same modem problem as the versions after it. As mentioned above I tried flashing a modem over ADB. I took out and re inserted my SIM card. In the end, I tried this guide here to restore my phone to it's original state. The guide flashes the stock versions of everything via ADB. Though it did return me to unrooted COS 12.1, it was not able to resolve my data problem.
After the total reset, all I can think that could be causing it is a hardware problem or that it is caused by something not reset in the 100% restore above.
If any of y'all can help my solve this, or at least offer insight, I would be very grateful.
Preemptive Edit I Guess: This thread was just suggested to me while writing this. I'm going to try the solution here and report back. It's OnePlus' reset to stock method. I'm not expecting much after my first 100% reset attempt, but we'll see.
EDIT: Ok, so the solution above fixed my problem... (edit again: turned out to only be a partial solution. See below.)
I would feel really dumb right now if it weren't for the fact that I slaved over this problem for a good ~8 hours before writing this post. Anyways, I'm not sure how to delete this post or mark it as solved. Sorry for the trouble y'all.
Never delete this post !!
I have the same problem, and I spent much more time to find a solution.
I will try this and will update.
Is it a clean stock rom?
Edit:
Didn't help for me ..
Still the same problem, No mobile internet connection.
Thx anyway.
Yeah, actually I was too hasty is identifying this as the solution. For me, the stock reset brought me back to CM 11 which didn't have a problem with mobile data. But if I try to flash a later ROM or update via OTA, the problem returns. I'm still trying to figure out what is causing it. The only information I can find points to it being a modem problem or APN problem, but I'm sure I have sufficiently checked both of those already.
Either way, I'll keep looking. If I find something I'll return here with it. Good luck

I gave this a try, but booting up after step 3 I still had the same problem. If I understand this method correctly, I think it is essentially the same as the other full restore methods I tried.
I think I may have found the problem though. I was looking at OnePlus' guide to installing OxygenOS. In it they said, "do not try to flash this build through TWRP. You will most likely lose your radio and IMEI which means a trip to our customer support." At this point I have repeatedly reset/restored my modem/radio so I don't think that is the problem, but I haven't seen anything about IMEI before. The IMEI is apparently stored in the EFS partition which as far as I can tell, is not touched by any of the restore methods I have tried. I took a look at my IMEI (about phone -> status) and it turns out my IMEI SV is 00. It's supposed to be a 16 digit number. I found a guide to fixing it, but I think I will just contact OnePlus customer support first.
I'll be back later with my results.

I gave this a try, but booting up after step 3 I still had the same problem. If I understand this method correctly, I think it is essentially the same as the other full restore methods I tried.
I think I may have found the problem though. I was looking at OnePlus' guide to installing OxygenOS. In it they said, "do not try to flash this build through TWRP. You will most likely lose your radio and IMEI which means a trip to our customer support." At this point I have repeatedly reset/restored my modem/radio so I don't think that is the problem, but I haven't seen anything about IMEI before. The IMEI is apparently stored in the EFS partition which as far as I can tell, is not touched by any of the restore methods I have tried. I took a look at my IMEI (about phone -> status) and it turns out my IMEI SV is 00. It's supposed to be a 16 digit number.

Are you flashing each of the extracted .img files from fastboot, exactly like the guide shows, or are you doing something else?

Yep, I ran each command listed in the guide and my phone was definitely in fastboot. Each command had a collections of "OKAY"s and ended with a "finished", which I assume means it executed as expected.
I have tried 2 different sim cards in my OPO (of two different companies, one of them as mine), and mobile data worked perfectly. Is it possible that my phone is ok and the problem happened in the sim card?
AND... my IMEI SV is 00 too. please update here if it has a connection.
Thank you !

I'm not entirely sure what you're saying. Did it not work with the first SIM card, but it worked with the second?
Mobile data problem was occured (to me), after I rooted my OPO and tried to flash a new rom.
I still can't understand how it convinced my sim card, but the fact is that I tried two (to be sure) other sim cards which are not mine, and mobile data worked well.
When I returned my original sim card, problem started again.
So I am almost sure that sim card has a connection, but can't understand why. And why it happend precisely now, cause it worked well over two years.

Why don't you flash twrp flashable modem?
If your network is present but no data , mostly data service problem. Are you pay your mobile bills ?
Are you activate data services ?

...yes i paid my bills ..
- my network connection to provider is dead...it worked perfecly for 1 month out of the box (see original posting for detailed action i took) this thread is about lack of data connection...but also MODEM related???
- tried the brand new simcard in my old Samsung sII... works perfetly, network connection with provider, data connection and calling..so no simcard problem
Long shot. Change any APN settings from IPv6 to IPv4. That was my problem when I had text/voice but no data.
I made a post on this and then called att gophone, due to seeing other sims working on this thread, and he helped me to fix. Posting my fix here in case others with isue find this post instead of mine.
Turned off wifi.
Turned off cellular data.
Went to APN and changed the apn (ATT Go Phone) from pta to nxtgenphone.
Turned on cellular data.
Finally had H+ above he signal bar, but had an X inside the bar.
Don't know if he did anything on his end, but the X went away after a couple of minutes.
Data was working, albeit kinda slow.
Turned off phone for three minutes per ATT rep.
Rebooted.
Data still slow, but it is at least working. Thinking I need to flash different modem. Battery usage has been higher the last day or two since I flashed c7 anyways.
