IMEI restored, still no data

Trying to help a friend who lost his IMEI (showed as 0), I restored it with the QPST method successfully. All the numbers are there and the IMEI is correct, but it still doesn't have data. I tried calling the number in the older efs backup thread to reprovision, and it didn't seem to do anything, but while I was messing around with it the icon popped up and I had one bar of 4G, but it disappeared after a few seconds. I'm out of ideas and I would greatly appreciate any help. Thanks!

Have you used Odin to restore the stock rom?

I tried, but but it failed, and don't remember the exact message. It's just on root66 right now.

If on stock (root66 sounds) dial: *2767*3855#
Back up anything you may want on the internal storage before doing so. Should fix it if it's fixable.

This ^^^^.
I had lost mine also and followed the same instructions, got it all back, but no data return. You need to reprovision your phone by following the key sequence. I think you need to be stock to do it too (could be wrong). After doing that, all my stuff returned to 100% fully functional.

You definitely need to be on stock for it, though? What's it do specifically? I never outright lost my IMEI, but I did have a problem where data would intermittently cut out and it didn't display a phone number in the system info.
After a wipe and install it seemed to be okay, but now I'm without data. Phone number and all the other numbers are there, though. If I dialed that on CM10, what could I expect?

I already tried that, it didn't work. I just tried it again and it still didn't work, but I left it locked for a while and when I unlocked it, the 4G icon was there for a few seconds, and then went back to no signal and it hasn't come back.

Hmm if that doesn't work I'm not sure what else there is. Maybe a new SIM or phone, all I can think of

a new sim is needed, or you just have a data-bricked phone if that wont work... sorry bud

I'm not sure what it's doing, but I don't think it's unrecoverable. If I leave it for a while, when I unlock it I'll have a bit of 4G signal, then it disappears after a few seconds. I was able to use the browser while it had signal, but when I try to make a call it says "Mobile network unavailable." I did receive a few texts, I'll test sending them. Under Settings>About device>Status, all the numbers are there and everything looks normal except these:
Network - Searching for Service
Mobile network type - Unknown:0
Service state - Out of service
Mobile network state - Disconnected
Thanks for the help so far.

Have him activate another phone on his account and then reactivate the s3. I'm not sure if this will help. It's only a theory really! If you decide to try please Let me know if it works. Thanks

On mine, I restored to the Nandroid backup I made of the stock rom before switching and dialed the number mentioned before. That brought it back to out-of-the-box stock. Set it up, tested data, rooted, unlocked bootloader, installed CM10, tested data, restored apps, tested data, made another Nandroid backup, restored system apps and preferences, and everything's fine now.
My problem was really similar to that one, too. It started when the phone wasn't coming on when I pressed the home or power buttons, and after a battery pull it showed the phone number as "Unknown." A wipe and reinstall of CM10 showed all the correct numbers in the right places and seemed to fix it all, but data was back out in time. That was how it was every time I reinstalled that way; it'd work for a bit, then stop until I reinstalled again. Restoring my IMEI backup as a "just in case" hadn't helped either. Getting everything right again was arduous, but worth it.

Alright my dad has got a similar problem. He lost his IMEI before, we managed to get it restored and data working and all that good stuff. Well today he had to fly to Denver and put the phone into airplane mode, well when he came out of airplane mode it was stuck on roaming mode, and network is "Unknown" his IMEI, phone number, and all those numbers are correct but hes still stuck in roaming. We tried pulling the sim card, and going back to a root66 backup and then reprovisioning the phone. Any other ideas? Should he go back to complete 100% unrooted stock and then reprovision? Any help would be great

I've had the problem come back for me, so disregard my earlier post. I'm back on stock now with no data issues so far, so I'm going to sit on that for a bit to see if the problem is definitely with CM. It's been gradual every time I've fixed it; last time I lost LTE before 3G.

Restored a Nandroid. LTE isn't working though, so I may dial *2767*3855# to go back to full stock and see if that fixes it. Currently 3G is still okay.

A question...
Those losing their IMEI numbers... Is this happening on the locked bootloader? Unlocked bootloader? Both?
I've been digging through the forums trying to ferret out a pattern, but it's not presenting itself to me. Maybe someone else has seen the pattern?

Can't make calls or have any service

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

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:

[Q] Verizon Galaxy s3 roaming only, not activating

So I'm totally at a loss of where to go or what to even search for.
I have a verizon Galaxy s3 that I rooted and unlocked the bootloader on. I flashed a couple ROMs and now it won't connect to the network. It tells me it is in roaming mode only. I called verizon, but they said to just return the phone because it won't talk to their network.
I've read some things about "triangle away" and I kind of tried that. But it kept telling me that my flash count was 0 anyway. So it didn't do anything.
My IMEI and ICCID are correct to my sim card and phone. I originally flashed CM10 for the verizon s3 and it worked great for a few weeks. Then I tried a couple others and they worked also. Then I flashed the euroskank ROM, and that's when it no longer would connect. I went back to a previous nandroid, and still no connecting.
I don't know what the problem is, or what to search for, or where to go.
Should I try to install a stock rom. I know I keep seeing things about odin and installing the stock rom. Should I do that? That's something I haven't tried yet.

So, I tried reprovisioning the phone with *2767*3855#
And when I did that, it said sorry, your phone is not yet activated.
But I know it is, or, at least was activated. And when I call verizon they tell me it has been activated already. I don't know what to do. I'm thinking of trying to go back to stock

Same Problem
Flashed CM10.1 nightly just to test it out and then boom, no more connection. On any ROM. Scariest part? I have gone through the restore process and am now back to an unrooted phone with out of the box firmware. I believe I will take it back to Verizon now and see if they will give me a new one.

So I don't know if we have the same issue or not. But I got mine working for now. Don't know if I'll run into problems later, but this is how I got it working right now.
First, I installed back to stock settings and radio. I followed the instructions in this post
http://forum.xda-developers.com/showthread.php?t=1762709
I did the stuff in section 5. Including Flashing a Stock Radio. So I went back to the VRALG1 4.0.4 ROM.
And I did the I535VRLHE radio.
But it still didn't work. BUT, once in stock settings, I did the reprovisioning.
*2767*3855#
And then that finally worked, it went through, and my phone activated. So it works now. Hooray!
But I REALLY really want to know what happened. So I can avoid this happening again in the future. Can anyone tell me what happened, and why this fixed it? And how to prevent it happening again as a flash more ROMs in the future?
Also, SpecePatriot, let me know if that works for you. It'd be good to have more than one source to know that works.

Well that's good to know that you got it back working again. Sounds like it might be just be the ROM and not anything weird that we did to cause the loss of connectivity.

I had the an issue with my phone stuck roaming and this method worked great! Only problem I came across was trying to run Samsungs update for Jelly Bean, Every time I attempted to update my phone would crash and go back to ICS. Luckily I had a back up so I wiped my phone, restored from my previous backup (which had Jelly Bean) and worked without roaming issues!
My input is if your having roaming issues is to use a backup you made before you had the roaming issue. Follow this tutorial above to get your phone back to stock, root your phone, then restore from your backup through CWM or whatever you are using.
I am not too sure what causes the roaming issue but I did notice while looking for networks, my phone found ATT ad TMobile haha.I am assuming what happened was that the Cyanogenmod update I was downloading automatically was set for another carry which changed my wireless settings. I will be downloading nightly's manually for now on lol
Thanks for this fix, Saved me a lot of time and aggression

My S3 is having the same issue after a CM10 modification. Reflashing to a stock ROM fails, wiping and reflashing fails, trying a different rom on cwm fails, no backups to flash to (all result in error). So I stumbled upon this thread, read about reprovisioning, and I took it to mean input the numeric code into the phone dialer. I did that, and nothing happened. Can anyone provide insight on reprovision and how to do it? Google search on reprovision isn't giving me any hints.
If the reprovision is just failing and I've been doing it right, does anyone have any other suggestions? Really hoping my phone isn't soft-bricked with no ability to call/text.

Hey guys, when you provision does it wipe the entire phone, including the SD card? (internal SD card and external SD card)

stuck...
I tried all the above, stock, radios, kernels, codes, ##RTN#, none of it works, my radio works cause i tried 911 and it jumped on roaming and began to make call at which point of course i hung up before letting it connect any words of wisdom... at this point just a tablet for wifi

I have a galaxy note 2 on Verizon. This used to happen to me on CM 10.1 first stages but issue got fixed as the nightlies started. It only happened to me when I sometimes rebooted the phone or when the battery completely drained from 100-0% then when I would charge it and boot the phone it would show me an x and no signal bars. I would have to restore to a TW rom to get it to activate again but going into settings and switching to CDMA/LTE mode. Now I'm on ParanoidAndroid 2.99beta ROM and it still gives me that issue. Hopefully soon it will be fixed.:fingers-crossed:

Thank you buddy,
This helped me get my phone back in working order -- For those of you wondering why the "*2767*3855# is not working is because you are using the wrong flash. You must use "Official VRALG1 4.0.4" - and currently the link is down on the thread - I just googled it and found it elsewhere. I tried one of the other OTA's and it would not work. Also, do exactly as netskull described - even regarding the antenna. When using VRALG1 4.04 - The second i entered the last "hashtag (#)" it popped up another screen which helped get my phone working. I did not have to press send or anything. Kind of sucks that I lost all data on my internal card, but I DID back it up and now I will have to go through and restore. Since some people were wondering -- It did not mess with anything on the external card... It did unroot my device, however, so I will have to do that again as well.
For some reason, flashing the latest MIUI messed up my phone and put it in roaming all the time. Oh well, happy i got it working, and subscribed . Thanks once again Nertskull.

[Q] At a loss, data but no voice/sms

I was running the latest stable version of CM10.1 on my GS3 and all was going well until someone sent me a text message and I tried to respond. I was greeted with the error of message not sent. I attempted to text someone else to have the same error. Attempting to call someone will just hang and eventually say call failed.
I thought it was a radio issue so attempted to flash different modems but had the same result. So I restored my previous rom Beans 11 that was working after wiping and the same issue. Data works perfect, but voice and text does not. I searched and odin'd back to stock VRLG1 and entered *2767*3855# in hopes of that fixing the problem, again no voice/text.
Any suggestions further help? I don't know what else to try!
*CM10.1 was working fine, and then calls/texting stopped but data continued to work without trouble.
*IMEI seems to be intact
*Flashed backup of known working rom and issue still persists
*Flashed back to VRLG1 and attempted *2767*3855# as per another post to no avail and this is where I sit.

Same thing. Installed jellybeans 12 now I can't call or text. Prior text was hit and miss some days....restored stock rooted image flashed other Roms....no help. Dialed the ** number....so screwed. Ayneegry should have backed up my few several times. No idea what to do.

When you say "Data" do you mean wifi or 3g/4g? If you have no phone/text/3g/4g then it's probably your imei. Check under phone settings, see if it's gone. If it's gone you gotta restore, do a search.
If you have 3g/4g then I don't know what the problem is. Sorry, just trying to help

Odin back to ICS and reprovision your phone by going into the dialer and typing *2767*3855#

rgrossie - data as in 3G/4G works no problem... phone showed IMEI still there but followed a thread to restore it anyway to make sure that wasn't the issue...
Edgehood -- I've tried that, and that's where I currently sit, stock ICS with 4G data but doing the re-provision doesn't seem to fix anything -- occasionally a text will slip through, but I'm unable to reply

I hear ya, if I can't figure out what's up, I'll end up having to go back to verizon and see what I can do... It was out of the blue, everything was working and then suddenly it just stopped. Happened on a flash that was a little over a day old, so who knows.

Check Mobile network
I have thiss problem happen occasionally when I flash custom roms. Look under your mobile networks, see if either CDMA/SIM is checked or NV. If NV is checked switch to CDMA/SIM and then reboot. That seems to fix that problem most of the time.
Edit: After some tests found out this doesn't always stick, but I did find out that after switching from NV to CDMA/SIM turn on airplane mode so the radios are tunred off, wait a few moments, then turn airplane mode off. That worked more consistently than restarting it.

Edgehood -- I've tried that, and that's where I currently sit, stock ICS with 4G data but doing the re-provision doesn't seem to fix anything -- occasionally a text will slip through, but I'm unable to reply

Did you ever fix this? I currently have the same problem and have no idea what to do.

i had the same problem but a imei/efs restore fixed it. My imei was not missing but data worked and not calls or text. Changed sim and still same, even odined back to stock and unlockex and rooted no luck restored nandroid no luck. Then restored synergy imei/efs backup and good to go. Hope it helps.
Cruzin' tha Galaxy SIII via Obsessed Rom / "INAPPROPRIATE" Kernel

I had the same issue two days ago when I flashed to the latest MIUI Rom. Here's how I fixed it.
Go into settings, mobile networks, make sure subscription is set to SIM. After that open the phone, type *#*#4636#*#* make sure it's set to LTE/CDMA/AUTO
Reboot phone and all should be well.

If you Odin back to the original stock unroofed ROM, you'd have to take all the ota Verizon updates to vmf1. Then reset your phone.
Pain in the a$$ but has always worked for me. I had same problem running carbon.
I read in another post that Odin back to root66, them reset your phone would work too.

No cell signal, wifi works

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.
