No service after reflashing to stock [Solved]

Had my nexus rooted since day 1 and never had any issues. Lately i've been trying to use Barclay's Pingit app which doesn't work on rooted devices. So i reflashed to stock through the galaxy nexus toolkit. I did get service on the stock rom, but i've since tried a nandroid restore of my CM10 and it appears to have screwed something up. First off, the restore completed in 4 seconds, so it obviously didn't work. I'm using TWRP if that makes any difference.
So i tried a wipe and flash other roms, but still no service. Even after going back to stock, still no service. I'm assuming the botched nandroid restore has possibly damaged my radio somehow? I did try to flash another radio, and it flashes ok, but still no service.
APN settings are fine. All i get though when i try to connect to a network is "Can't connect to this network at the moment, please try again later".
I'm on 3 UK. Tried connecting to other networks, but still the same issue
Just tried flashing a new radio through fastboot, flashes fine and shows up in baseband version, but still no service...

Have you tried getril app? If your radio interface layer doesn't match it can fix it.

Yeah i tried it earlier, no luck.
Just tried again to make sure, still nothing

I have had some bad flashes with twrp. If I were you I would try cwm and then flash a new ROM.

Op, do you still have your imei? Try another simcard have you?

Yeah i've tried several new rom flashes through CWM.
@bk201doesntexist - Yeah the phone has an IMEI in the status menu. I'm wondering if it's blocked since my provider accidentally cancelled my contract a few months ago, and i didn't say a word
Scrap that actually, apparently Three UK can't block IMEI's for some reason...
Funnily enough, i tried a sim card from another carrier and not only did it not connect to any network, but now when i go to search networks it just says "Error while searching for networks".
Edit - Called my network provider, they said my IMEI was wrong. At the minute it starts with 0049, which it shouldn't apparently. I dunno how this got changed in the first place.
Ok, so i've looked into the imei 0049 issue and it's starting to make sense. I looked in the /factory folder and it's empty, well apart from lost+found but it's empty. I assume the only option is to send it off for repairs? I do still have a nandroid backup on my computer and it has efs.ext4.win on there. Gonna give that a shot.
Edit 2 - Ok so I updated TWRP as my version was 2.2. Attempted the nandroid restore again and success! Got my voice and data back!
Thanks for the suggestions, its been a stressful day and hope this can help somebody else in a similar position

Yeah i forgot mentioning the fake imei thing. I was thinking about the /factory partition being null, thats why i spoke of imei.
Please edit the thread title to include tag [SOLVED]. Thanks.

[Q] Insert Sim to Access Network Service.. IMEI Null

Hey Guys,
I have an AT&T Model SGH-1317 Note 2. For use on other networks, I unlocked the phone using the *#197328640# menu option. However, the phone failed to start the hot spot stating Mobile data was unavailable or Invalid Sim. However, I am able to tether perfectly using the same sim on an another S3 so I was sure its nothing to do with the sim or network operator settings.
I looked up and found XDA website with tons of information. I assumed my phone was locked by AT&T. Hence, I rooted the phone using CF-Auto-Root, backed up complete data using Titanium and using Rom Manager I installed the Crash Aroma 4.1.2 Rom. I wiped the data and cache 3 times as suggested. However, after the boot I am unable to connect to any mobile network. A Click on Mobile Network says "Insert Sim Card to Access Network Services". Dialling for IMEI number prompt a Null.
During Installation I noticed the Crash ROM has overwritten the Radio.. and I am assuming this is were the problem lies. but I leave it you experts.. Request Help!
Sunil.

What carrier are you using the device on?

Am currently on Du - A network in Dubai, UAE. I have been reading more forum information and some suggest that this may be related to the EFS folder getting corrupted which may cause the IMEI number to fail. Some suggest that there are software to rebuild this information by using the IMEI number behind the handset..
I also noted that my phone model has also changed to GT-7100 instead of SGH-1317, Wonder if the Crash ROM was apt?
Would you suggest installing a Jedi Rom specifically built for SGH-1317... or is the damage already done?

Back Online
Since I found no replies.. I had no choice but to give it to the Pros.. I handed my phone day to one of the Unlocking experts at a mobile store… He was confident that his technicians would resolve this. But after 2 Days, they have given up.. He suggested the phone would fetch me US$ 10 if someone used it as a demo unit at a mobile shop..
I was sure this was something to do with the Modem, IMEI and the all important NV folder. I was able to find a Stock ROM for the SGH-1317 and I also found a link at XDA about using EFS pro to change the IMEI.
Using Odin software, I flashed the phone with the stock rom. Unfortunately, there was one error when it tried to communicated on com1. Having no choice, I continued. Restarting got the AT&T style boot but it again froze on the Samsung screen. Dreading the communication error, I restarted several times with no results. Finally I realised if would be due to the cache and user data. I reset the phone to factor settings wiping out the user data and Whola.. The phone sprang back up..
Lessons learnt.. Backup your rom and data before playing with custom roms. Read Read Read and don’t flash in the middle of the night..
Since I am back online, I plan to stick to the stock and crappy 4.1.1 with all the AT&T dead weight. Will live without the ability to Tether until my fingers get warmer.. It won’t be long as I am already bit by the Custom Rom Devil..
Don't Give Up Easy..:good::victory:

Please I am having the very exact same issue and can't seem to have it fixed
Using CMW I also flashed it back to stock rom, didnt have any problem or errors doing it but im still getting No SIM Inserted. I have deleted cache and user data several times... Tried flashing CM10 and CrashRom see if they made a difference and still No Sim Inserted... tried 3 different kernels and still same issue

I have the exact same problem since yesterday. I've tried everything and anything to no avail. I'm very close to returning the phone.
I would really appreciate any input.

Same issue
I flashed crash rom 4.5, over the stock kernel and it gave me that same message. I've tried everything I could think of, which included everything in this thread to no avail... any further advice would be greatly appreciated.

Your username suggests that you have the N7100 device ??
If so. ..you are in the wrong place for support. ..As this is the SGH-I317 section.
If you are showing IMEI NULL with no baseband you may have to restore your backup image to correct the problem. .
If no backup image exists. ..you will need to flash a factory N7100 image from your section.
Look for the return to stock thread for your specific device and that should fix you up...
The CF AUTO ROOT files are device specific. ..so I hope you haven't damaged the partitions.
Good luck. ..g
Edit:
This will help. ..and will place you in the right section. ..
Just go to page 1...good

Today,no mobile service - have worked hard for solution - no success

Hi there
I am in New Zealand, recently rooted with DR Ketan’s help and installed PhilzCWM. Also on Ketan’s advice, I backed up my EFS.
My problem: just today I realised I cannot send text, or make phone call. I am on X-Note ROM from 3-4 days ago. I am very sure that after installation, I had normal Mobile connectivity and was surprised to find I didn't. Not sure if my EFS became corrupted, or other ROM setting is wrong.
Under Settings About Device:
My SERVICE STATE says Out of Service
My Mobile NETWORK STATE says disconnected.
My phone number says UNKNOWN
What's weird is
My IMEI lists a long number, assumed correct and not corrupted
So if my EFS partition is corrupted I assume I wouldn't see any IMEI at all?
Far as I know my SIM is activated (I am on a company plan & coworker's phones are normal)
Just now I restored my stock nandroid and .... same thing! No service. So I doubt it's even a modem problem.
Guys I'm screwed, any tips what settings to check etc??

sounds like your IMEI is invalid. i had something random recently. all my flatmates use iphone 4s. they had no signal when @ home. cant send texts etc. wifi works.
then next day my LTE N2 did the same thing. I changed MODEM/BASEBAND problem corrected it self. went back to old MODEM/Baseband. no problems since.
only other thing i can think of is, someone has reported your IMEI to police or your provider..
does it say "NOT REGISTERED" ? or something similar where your provider name appears?

Hey thanks for th tip.
My phone recognises Vodafone as my provider but still won't connect.
I will try flashing a different modem, I may not have paid enough attention to different versions when I flashed the aroma installer.
Thanks, I'll report back.

update: Vodafone shop confirms my SIM is 100% good, and it works in another phone. So I think you're right, my IMEI is fukt.
I was told by Voda that my proper IMEi is listed on my phone innards. The IMEI shown in phone settings is waaay different. So it's corrupted somehow. I gotta familiarise myself with how to flash my backup image. Damn just what I need on beer day Friday

I restored my backup image of EFS/IMEI - it solved my problem.
Because there was an IMEI listed in phone settings I wrongly assumed it was the correct one. So flashing ROMS can muck up your EFS.....thank god for backups

you can still use the custom roms. just if your IMEI stuffs up, there is methods to reset it. i had to do it once. wasn't that difficult but was rather troublesome. i just wanted to use the custom rom at the time.

Note 2 Emergency calls only No registered on network

Good evening friends.
I am a proud owner of a Note 2 GT-N7100
My problem is to delete some apks from the system folder with root explorer and it turns out that after you lit the phone and stood frozen, then what I did was flash it to the original stock with odin samsung.
but surprise the other day when I try to make a call came a sign that says not registered on the network and down the notification bar I get emergency calls only. The signal bars go out and have all that when I flashie also never saw what to backup efs folder.
I searched google thousand tutorials to troubleshoot failures, modem and changed everything but I could not fix it remain the same.
Is it only want to be told if you have a solution, if I have to take it to repair or that I can do?
Thanks in advance.

Was the phone alright immediately after u flash odin?

Check imei with *#06# if it returns your imei then your baseband is corrupt if it returns other number starting with 0049 than your efs is corrupted

Guys I had the same problem (No IMEI) with my friend's S3 Mini. I went to Sam Mobile and downloaded the Asian firmware for S3 Mini and flashed it with ODIN. I got my IMEI back.
Download the stock 4.1 official Firmware or 4.3 Beta firmware and flash it. I hope it works for you guys.

Solution..?
I have the same problem..Did anyone find a working solution..? I am searching it from a week and tried all possible ways, no use..
Still says "Not registered on network"

It happened to me when I travelled to another country. I solved it by changing the type to G2/G3 only, removed then replaced the battery & SIM.
