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

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

Lost IMEI Number?

Hey guys. I would love some help here; recently I had my Nexus 4 lost, and found again. I called Virgin (My phone company) and cut my phone service off. Once I found it, I called and turned it back on. For about an hour it kept saying that the network could not be found, and when I tried to force it to connect in the settings, it said my sim card couldn't be used on the network. I did factory reset from the menu, but it only got worse. It than wouldn't even recognize I had a sim card. I looked online about IMEI and typed in #*06#* or whatever it was, and there was nothing there. Completely blank. I have no idea what to do, and am currently trying to flash stock rom. If it helps, I was running Paranoid Android 3.99 RC2 when I turned my phone service off. Any replies would be appreciated. Thanks.
*EDIT*: I restored to Android 4.4 using the factory image provided by Google, and I now have a IMEI number, but it still wont allow me to connect to the network.
*EDIT 2*: After doing some research on the Virgin site, I found out that there was a blacklist that your phones IMEI goes on after reporting it stolen. Basically, when I called in to get it off of it, it was never taken off. Those ****ers said it was going to cost me $150. This thread can be kept for future reference to other people, or deleted if needed. Thanks.

Thanks for the info, but I now have a IMEI number when I flashed Google's stock 4.4 image, but it still says it cant connect to the network. Any ideas?

Just restore any CWM or TWRP backup. It worked for me after i lost my imei and basband while flashing 4.4.

Nothing to do about a blacklist. Ask them again and explain the situation. Contact a consumer rights organization otherwise.

[Q] LG Optimus L3 (e400) data not working/APN not saving

Hi, first of all I must apologise for my lack of technical knowledge. I recently rooted my phone and installed Cyanogenmod 9, but I have found that I cannot get a mobile data connection. After looking into how to solve this, I found out that I had to enter APN details. I attempted to do this, and used the menu and selected save after entering the details for o2 pay and go mobile data. After several reboots as other threads on the web have instructed, I still found that my settings were not saved.
Someone posted a cm7 fix for this, and somebody else posted a stock backup of APNs which I was unable to install because apparently this cannot be done on Android 4.0+.
Does anyone know of a solution to this problem?
Thanks.

try other

No Network

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.

No Service with Sim Card Inserted

A few days I woke up with no service on the Nexus 6p. This was a few days after updating to the latest oreo build. Sim card seems detected because when I take it out another message shows up "No SIM card - No service", and when I put it back it only shows "No service". Tried putting the card in a Nexus 5X and it works fine.
Tried the following with nothing working so far:
- Switching 2G/3G/LTE and rebooting in between.
- *#*#4636#*#* and turning off the radio, switching between the different options of GSM/LTE/etc...
- Restoring a working nandroid backup
- Reflashing different ROMs
- Factory reset
- Factory reset then flashing ROMs
- Wiping cache and dalvik
- efs fix in twrp
Hardware version ANGLER-VN2
IMEI shows up under IMEI information tab but not under SIM Status tab, there it shows not available.
I live in Ontario Canada, carrier is Freedom mobile.
So now I'm stuck, tried calling google and hwawei and they won't do an RMA because my warranty is expired.
Anyone has any ideas to try?
Thanks in advance.

Not that this is going to help, but this has GOT to be an Oreo issue, myself as well as at least 4 others that I have seen has been getting the No service, or No Sim, mine did the No Sim, then started bootlooping.

No this has nothing to do with O.
Which version phone do you have? H1511 or H1512?
What country are you in now?
What is your carrier? If MVNO state that.
Are your IMEI and phone numbers showing up in settings?
Everyone, please put the most basic information in your profile like where you live, which carrier you are currently on, and maybe even which variant of your phone.

I updated the first post with more info. How do I tell if I have H1511 or H1512? I bought it from the google store in Canada.

More information is good. Please update your XDA profile so the next person trying to help can check there first. You can find the device variant by booting to bootloader (not recovery) and using the vol toggle to navigate to "Barcodes". IMEI should show up there too. Date of manufacture, Serial #, etc. I think you should have started a normal thead, not Q/A, BUT your IMEI and a lot of other information should be showing up under SIM info. That's a problem. Second, you say you did the EFS fix in TWRP. Can you explain how you did this? Did you use one of YOUR OWN TWRP backups which contained the modemst1,modemst2 and restored ONLY those two partitions to your device? Did you receive any confirmation or error? Have you tried using a SIM from a Rogers or Telus in your phone to see if the SIM info shows up?

Thanks for the help, I'll update my profile with this info as well.
in the bootloader the IMEI shows up along with the rest of the info. It's a H1511 device.
The EFS fix is by following this: https://www.theandroidsoul.com/fix-empty-imei-corrupted-efs-no-sim-unknown-baseband-wifibluetooth-issues-restoring-twrp-backup/
is modemst1 and 2 contained in the twrp backup? and if so how do I restore it? in restore options there's system, data, vendor and boot only. I guess it's an option in the backup that I haven't selected?
I tried another SIM also from freedom and it didn't work. I don't have a Rogers or other SIM to try currently.

Right, so if you didn't ever select the EFS partitions when using TWRP Backup, you never backed them up so under Restore they don't show up (so you can't use that method). You can however use TWRP terminal or fastboot to wipe those and reboot. I would be sure to try at least one SIM from either Rogers or Telus. If that doesn't work, then wipe the EFS partitions and let them rebuild (hopefully).

Definitely Oreo issue. Google messed with something and it broke data for many people. I have been troubleshooting this for the last week (Verizon, US, fully stock 6P) and finally found a thread where a Google rep acknowledged the problem and said it was high priority for a fix.

I wish you luck with that one @LucJoe. This has been happening for the past 2 years from MM, N, and now O...and XDA is full of threads (just look). So you just go ahead and wait for Google to fix it for you, LOL. - Not a new issue related to O.

Never happened to me before updating. The data issues manifest differently across different carriers but for some reason Oreo likes to play it safe and disconnect data. I have not been able to get LTE for more than a couple seconds, but will get slow unstable 3G occasionally. Google confirmed the issue here: https://productforums.google.com/forum/#!msg/phone-by-google/kw3ZcXd1BVs/7HYuANdoAgAJ

A recent success using terminal from TWRP (or the OS if you are rooted). You can also use fastboot to do the same thing using the commands in the article posted in this Q/A (method 2). Good luck! See thread here.

This seems like it's a different issue described in that thread. I'm not running out of data, there's no service and no connection of at all to any network.

I did find that and try it before posting here. It did nothing to fix the problem. It did say that something was copied over '4 MB copied, at 14.3 MB/s' something like that but nothing changed.

I also have the same issue. Have tried everything including going back to stock 7.1.2 & locking the bootloader. Nothing seems to work. Interestingly, when i pull up the hidden phone diagnostic menu, it shows all cell measurement info which means that the antenna is receiving signals but the phone somehow is not registered on the network?

I can wipe those partitions with fastboot but is it safe? I have never used TWRP and my problems started after updating to Oreo. Is there a chance the official OTA could corrupt those partitions?

@LucJoe- That fix is not for you. That is for users who have no IMEI or phone number under About Phone>>SIM info. Your issue (as I understand it) is a weak and intermittent signal that keeps disconnecting LTE and sounds like a carrier or SIM issue. Why not go get a new SIM provisioned for your phone. That or pop somebody else's SIM in your phone and see if you get a different outcome.

Yes that was my first thought as well. I got a new SIM, then another one. So 3 SIMs now with the same result. I've been on the phone with so many techs from Verizon/Total Wireless and none of them have any answers. If I put the same SIMs into a Moto E4 I picked up for testing, it works fine. But the 6P immediately disconnects from LTE then bounces between 3G/1X.
My next test is to try a SIM from a different network I guess... maybe Verizon is blocking my 6P. Or maybe my LTE radio is damaged somehow.

So I did this using TWRP but wasn't sure if it actually went through or not. I did it now through adb from pc and also fastboot and it says permission denied. Any idea how to bypass that?
