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

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
I have a Sprint Galaxy S4. I lost my mobile network after I flashed a new ROM. I decided to go back to 100% stock and try again and it still didn't work.
1. I went back to stock - flashed Sprint firmware. This brought my mobile data connection back.
2. Rooted the phone. Checked mobile data connection and it was still working.
3. Installed a custom recovery. Checked mobile data connection and it was still working.
4. Installed a custom ROM. Mobile data wont work.
I've tried a couple of different ROMs so I dont think thats the issue. Can anyone help?
Check you have your Imei in custom Rom.

Hi good people, I am facing a problem. Around 8 hours back I tried calling someone but the call didn't connect so I restarted the phone and then I lost the network. I tried reboot, flashed different ROMs (unofficial CM14, cm13 nightly build n MM nougat backup), tried with GAPPS and without GAPPS but the problem is persisting. I even tried swapping the Sim cards before that but of no use. I tried debugging by using *#*#4636#*#* but ping test is failed and also there is "TURN RADIO ON" I believe ideally it should be "TURN RADIO OFF". please have a look at the screenshots. I'm almost dying without making important calls.
Update: Guys I have got it working.. Kindly look into my below posts. Please don't misguide people for small issues.
Thanks
In the screenshot we can also see, GSM SERVICE IS OFF. it stays the same even after clean flashing a new custom ROM.
Got it working. Flashed latest COS ROM file however the situation was still the same. Then I removed sim, switched on airplane mode restarted. After reboot inserted Sim then again restarted n then I got the signal
1. Removed Sim card, switched on airplane mode from both power menu and notification toggle.
2. Restart, inserted Sim card and switched off airplane setting from setting. (Notification toggle and power menu didn't work) then got the network.
Please note I tried with only one sim in sim 1 tray. Later I got the network for 2nd sim as well

Which rom did you flash and what was your method of flashing?
You also said simply flashing didn't work. It was what you did with reboot, aeroplane mode and taking out and reinsert the Sim that worked?
I've had the same problem for almost a month now... and i gave my phone to the service center. They called up to inform me that its a motherboard failure and they'll fix it.. I'll provide further info when I get my phone back (probably in 3-4 days)
P.S I tried almost every method to make it work. So if you couldn't make it work in first 2 days or so, dont waste your time and just give it for the servicing (make sure its in Stock OS so that they dont ask any questions about root xD )

I flashed almost every latest ROM. But no ROM got the network back. So as a last resort I flashed COS 12.1 and still didn't get the network. Then I removed both the sims, activated flight mode restarted the device, left it couple of minutes and inserted only one sim in first slot. Holla I got the network. Then everything is back to normal
If u r facing the same problem I would suggest u to activate flight mode n restart. If it doesn't work try by removing sim cards, if it still doesn't work try COS 12.1.

Usual procedure of flashing. Wipe cache, dalvik, system and data. Flash ROM + Gapps. Reboot
Try to search in the forum. There is a lot of threads with the same problem with the Zuk Z1. It is a hardware problem.

Your modem and baseband sections may be damaged. Modem structure is hidden under qualcomm structure. To Access and repair those sections, you need to do some modifications. I managed to make my Zuk Z1 worked again with some tweaking. Altering that part of the phone is illegal due to its restricted elements such as IMEI number. That's why I cannot post a tutorial here. İt is not allowed. However, I can help you if you personally contact me. I hope you get your signal back soon.

Please follow xda rules and don't tell people illegal things where they get in trouble. Keep in mind, that's not an illegal forum
Sure thing but I have already mentioned it. I didn't post anything illegal. So, take it easy.

Hi, I haven't still gone to the service centre. Kindly pm me the tutorial for getting signals back.
Hi there
My father in law has a p8 lite that i am almost sure had ALE23 firmware.
Now it is running ALE-L21C432B597
It is not a dual sim phone, but i find dual sim stuff on its menues.
That has been like that for a while (no idea how it got like that).
Now wifi died (it is either greyed out or yo turn it on and does nothing for a while and then goes off again). Tried factory reset, wipe cache, etc.
Then i tried upgrading firmware, but i either don´t know which one to use to upgrade, or the phone has a problem, because it verifies and then says it failed.
Fastboot key combination does not work.
After some/a lot of tinkering I was able to reinstall both the current firmware and the newest single or dual SIM ones.
Nothing fixes wifi/Bluetooth (just noticed Bluetooth is dead too).
I also remembered about adb reboot bootloader and checked that it was unlocked.
So I used fastboot to change it to ale-l23, fixed the balong thing, and still nothing.
Another thing that did not work or now, is adding a google account.
It stays in "verifying data" as soon as I try to add one.
So now my father in law has a phone with no google, no wifi and no but T_T

Hello, I have problem with my Redmi Note 7. A couple days ago I've changed ROM to Google Experience, but I came back to MIUI after hour, before that everything was alright, but now my phone is stuck on 2g network. I've tried many things from internet but nothing is working. APN settings are right, I tried to change settings in Testing - phone information2 because my sim card is in slot 2, but changing slots or putting in 2 sim cards doesnt work, in settings preffered type of network is set to LTE, on other phone everything is alright, I mean LTE is working, so its not because of my sim card. I dont know what to do... I hope someone will help me
Android: 10
MIUI GLOBAL 12.0.10 STABLE
I have unlocked bootloader and custom recovery Orange Fox Recovery

When it don't work maybe u have to clean all, but don't relock the bootloader. And after flashing you must reflash the customer recovery
