Not registered on network. Stock Factory settings

I know this issue has been spoken of in other posts, but nothing exactly like the issue I am having and all I have read are not with the s4
I am on factory stock Rogers firmware. I337MVLUAMG1 unrooted. "Not registered on network" is keeping me from doing anything. I can access wifi and all my APN settings are correct. Nothing in my phone looks wrong or out of place.
I have tried 2 new sim cards and that certainly isnt the issue.
My imei and serial are reporting a.ok
Phone was unlocked from rogers and previously being used with bell all with no problems.
I did try some custom roms before heading back to this and thinking perhaps something got screwed up. I inserted my sim after installing omega rom v11 and it has not worked. that was the first time I even tried a sim in the phone. So it has never worked since I got it. Which sucks because I don't know if it was something I did or something that was already in place.
I have done a factory reset with data from settings in the phone and also from stock recovery.
I have removed the battery, sim and restarted. Doesn't help.
Phone says "not registered on network" when trying to make calls and says unregistered sim card when dropping down notification bar.
Any ideas? Help? ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Edit: Ok, after some heaving reading I think the issue lays with the update to Omega v11. I think it changed the efs file structure to a new format and I need to use a newer modem to access it the new format properly.
Can anyone please let me know an mg4 or acceptable modem that would allow me to test this theory and if I can just flash the modem with the stock firmware.
Once again its an i337m currently running rogers I337MVLUAMG1. IMEI + serial working fine but no network access. Looking for a modem that will work with this setup to see if I can access a modified efs folder.
Information of modified efs was read here - http://forum.xda-developers.com/showthread.php?t=2377731

I had this problem and in my case was because a bad sim unlocking. So i just tradedy s4 for another one already sim umlock

Interesting... hadnt heard of a bad simunlock. good to know!
Any other options?
Answer...... NO!
!!!LESSON TO BE LEARNED HERE! BACK UP YOUR EFS FOLDER!!!!
If you are reading this and never done it... DO IT NOW!
It is a simple thing to overlook. I have been flashing roms for over 2 years and not once have I back it up... New S4.... not so good. Just sent for repair.
Now I wait to get the phone back so I can play with it again
BACK UP YOUR EFS

No SIM - Insert Sim card

hey guys,
I have just gotten my phone back from repair. It was getting the cracked lCD replaced.
So i went and put my SIM card into the SIM slot then i rebooted my phone, just to see a "No SIM" message which then proceeded to say "Insert SIM card". My wifi and everything is working and i can make emergency calls. I have previously had problems with my EFS folder and a corrupt IMEI but i fixed that issue and i don't believe that these two incidents are related whatsoever.
This is the thread with all of the information of my last problem. http://forum.xda-developers.com/galaxy-s5/help/service-t2898890
To try and solve this new problem, i have done the following:
1. Taken the sim card out and restarted phone and entered the sim card back in numerous times in various different sequences.
2. Done a full factory reset, reflashed a new rom, modem and bootloader.
3. Restored the EFS folder.
4. Tried a different SIM card.
This could be a hardware issue, but i feel as though it is software related, but i am no genius so i am open to any suggestions as to what it may be and how i may be able to fix it. If i am not able to fix it i will just send it back to the phone repairers and see what they can do to resolve the problem, but that would be the last thing i want to do.
thanks for any help.

not to worry. I have now solved the problem and everything is working perfectly.

And you did this by doing what?
Having the exact same issue on an S4 mini.

i was on android 4.4.2 thouchwiz, i then upgraded to android 5, which also meant i had to upgrade the modem, which seemed to fix the problem. I then downgraded back down to android 4.4.2 touchwiz and that solved the problem.
so maybe you could try upgrading your modem or something? let me know if that works.

By modem do you mean radio?
It's an unrooted phone in my case, unfortunately.

the modem is a file or software i guess you could say in which controls the the signal on your phone.
hmmmm, im not sure what you could do then... im guessing you do not plan on rooting either?

[Help] Sim card not inserted problem after flash, likely a software issue

So for ages i was getting no sim card inserted on my I9505 and figured it was a hardware problem as it would work sometimes if i pushed the tray really hard and so i replaced the sim card tray and all was working for a few days. I then decided to flash a new rom and straight after the flash all im getting is no sim card inserted.
Ive used odin to flash the stock firmware but still get the message. Ive used the airplane trick also with no luck.
Im totally convinced its a software problem because it happened instantly after a flash and ive only recently replaced the sim reader.
Any help would be appreciated.

hii , i guess you have imei problem , chech for #06# if your email code match the one below the battry.

It was AntaresOne & Alucard24's cm12 build. I tried flashing the latest modem and obviously when i went back to stock using Odin an older modem but correct one was installed.
Anyhow, i actually believe it was a hardware problem again. I think that when flashing a new ROM it gets very hot and this can cause problems with the Sim reader. So i took apart the phone and basically used some duct tape to make sure the pop connector thingy is securely pushed down and also the Sim tray. It seems to be working so far.
I will flash a ROM just to make sure it doesn't happen again.

So, I broke my S4's screen and had it replaced by Samsung. After that I couldn´t make phone calls through my network, I couldn´t hear anything and no one could hear me. But by using whatsapp everyhting worked fine. Also my phone stopped recognizing my SIM from time to time.
So I swapped my SIM card and it didn´t work. Then they told me the problem could be with the SIMS slot, and so I had it changed, and amazingly still nothing. And so their solution was to change the Phone's motherboard for a lot of money! Since the problem didn´t seem like hardware, I flashed a new ROM through Odin.
The SIM is recognized (it wasn´t anymore) but there is still no sound on phone calls. Any ideia? could a rooting, and installing a TWRP and flashing a new ROM work?
Thanks

Try to flash a custom ROM and see what happens
If it fixed you problem then the stock ROM is a little bit corrupted
If not then try to replace sound module of the device[emoji6]

SIM Card Not Detected

Hi, I've had some issues with SIM cards in my Mi A1.
I've tried rebooting and I've tried both SIM slots, but neither of them are detected. "No SIM card - No Service" shows at the top of the screen. There's nothing wrong with the SIM itself, it works fine in my old phone (a Redmi Note 3) so I'm not sure what to do now. Everything worked fine yesterday and I haven't dropped it, splashed it with water or anything since then.
Any help would be appreciated, thanks

hello brother please imei number check

hey
I'm having the same issue. How do you fixed it?
Thanks

I had this issue too, try restarting the device 2 or 3 times. If it doesn't work, try doing a factory reset.

was anyone able to fix their SIM issue?
my Mi A1 received an OTA update last month and the "SIM card not detected" msg
when I check my Network Settings, the menu options are all greyed out and i can't do anything with it
i've tried flashing many different versions of stock/custom ROMs
i've tried a variety of different SIM providers (Rogers, Koodo, Fido, etc)
i've even flashed a few modem versions to see if it would fix the signal (cuz that's how i used to fix my SGS2)
but nothing works... it's behaving as if there isn't a SIM card inserted at all
...which is leading me to believe that this could be a hardware failure
anyone with suggestions on how i can fix this? cuz otherwise, it's a great device... it runs AOSPExtended like a champ
thanks in advance
