Hey guys I'm having a little problem with my GT-i9505. Problem being that I cannot get any reception on my device. It first occurred when I flashed a 4.3 rom over my 4.4.2 rom. I've tried switching to several different roms, both 4.3 and 4.4, yet none can fix the problem. I've tried to flash at least a dozen modem's in a bid to fix it. I searched for the modem suitable to my device and yet they still didn't work. I even tried to just install the official Samsung 4.4.2 rom via Odin, yet I'm still having the same problem. My baseband does change whenever I flash a new modem, but I still cant get a signal. When I try to search for a network in settings it lists the main carriers in the UK, but when I try to select mine (3 UK) it doesn't allow me to register, clicking select automatically yields the same results too. I've been searching for hours today on how to fix this, but just can't seem to find a method that helps. Any suggestions?
Have you tried manually entering the APN settings for 3 UK?

Take your S4 to a repair shop. Use Phil,s recovery when you re-root, install Omega ROM or another Samsung based ROM and, using Philz Touch 6 recovery, make a copy of your EFS file so if / when it happens again you can reinstall Omega or whichever ROM you installed and, using Philz recovery, you can reinstall your EFS file.
To make the backup, reboot recovery - backup and restore - custom backup - x (only in efs backup) - start custom backup - choose where to put the backup.
I use Omega as a reference because I know it will not screw up your EFS file.

Is there a way to fix this without having to spend anything? I literally can't afford to take it to a repair shop at this time
Also, my IMEI still shows as it should (corresponds with the IMEI on the back of my phone)

I had the same problem with my i9500 after flashing a Slim rom Perhaps you can get a copy of an efs file from someone with the same phone and then put it on your phone, or get the information you need from your phone company.

Did you try to remove the SIM CARD and switch off /on the phone to clean internal SIM register and to reinsert your SIM card again?
This worked for me once.
Nothing is wrong with my Sim slot cause when my sim card is in i can see my network name Wen I slide down status bar, only that no signal at all
what do you see

I now have exactly the same problem as you. I tried (once again) to install a new ROM on my i9500 (SOKP this time) and now (for the third time) my phone won't register on the network. I'll take it to China Unicom in the morning and let you know what happened. Unfortunately I don't speak Chinese very well but I will try to watch what the repair guy does. Perhaps it will be of some help.
I took the phone to China Unicom but the tech that repaired it last time wasn't there.
So ur problem is not sorted then?

What u mean by purchase a new baseband bro?
did you try searching for a signal outside?
i'm on three uk network and signal indoors is absolutely atrocious! (especially since they started "upgrading" to 4g networks - i had the exact same problem with t-mobile switched to becoming ee, i don't know why these companies are so intent on breaking networks which worked perfectly before by "upgrading" them).
I got this message after updating to android 4.4.4.
What could be causing this?

If is not hardware, chances are that the efs folder is corrupted.
Try a different kernel
Try a different modem
Flash full wipe custom rom again..
Last flash stock rom...
If all fails the problem most like it is in the efs folder, if you have a backup restore it

same issue.
I have the same issue as described by the op.
I flashed back to official 4.4.2 and the problem persist.
IMEI number is correct.
IMEISV is 01
Ive been trying to fix this for over a week to no avail. Losing my mind. Is there anything else you can suggest to fix this issue?
Phone is an i9500.
Was really hoping for some help by now. This will be the second time ive posted to this site in the 2 years ive been here with zero responses.
As a side note. I wanted to add that at the same time i started having the "not registered on network" error my sd card stopped being read by the phone also. I replaced the sim/sd holder in the phone itself hoping this would fix both issues but it has obviously not. Still not reading the sd. Says its blank or unrecognized file system. When i try to format it it doesn nothing. This is the sd I had in the phone before having issues. It worked fine then.
The phone just suddenly stopped working one morning. I used it to send a couple text and make a call, next time i picked it up "not registered" issue began. No changes to the phone in between those times.
I figured I would add this info in hopes of gaining a response.
Thanks.
Hello.
I just flashed the latest Lineage Rom and i'm having a problem with signal strength, it's zero. I tried switching through 2g 3g and lte and no succes. Only thing that works is to shutdown-open the phone and the signal is ok for 10 minutes then it goes to zero. Should i try another clean install?
Usually the error is com.android.phone has stopped, when i try to switch networks i usually get this error.
Also the battery heats up but afaik its normal until the rom settles in.
[Solved]
1.install 12122016build(cyanogen) and and back up only boot from it.(via TWRP)
2.install the newest build(cyanogen) and restore boot from the TWRP backup you made
The error shouldn't appear when you try to change the network, I suggest you to do a clean install
I have the same problem... no one replied to me yet...do you have the SIM unlock screen on first boot? or you need to reboot once again after you install the rom?...

Change network by 2G, 3G or LTE? Did that, dosen't change anything, also i did a clean install again.
But at Network Operators it just says Searching... and dosen't find anything, it stays on Searching... for minutes.

On fresh and first time i open the phone it says that i don't have a SIM.
If i reboot it says the same.
If i close the phone and then open it, the phone reads the SIM for a few minutes and then it doesn't work.
Tried switching to Airplane Mode, switching 2g, 3g, lte, no succes.
You have the same problem in CM as well?
after installing the rom i dont have the sim unlock screen, on 2nd boot i have sim unlock screen, it says i have signal but calling doesnt work, data dont work, cannot search for networks too..and yeah after 10 minutes or so the signal drops out and i have no service
when i posted in the development thread because nobody replied in the Q&A thread i got s**t on that i should write to the Q&A thread and give logtcats too...
then i added the logcats and even posted in the Q&A thread again but no answer...

Newest build Cyanogen or Lineage?
Why don't you just install the lasted version and extract the boot.img from the functionality one without doing all that fuss backuping and restoring?

Well, did not found a functional rom until now, im just downloading different versions, flash them and see which one works, backup boot.img from the one that works and extract it in latest version.
12122016cyanogenmod boot.img and latest CM13 not LOS13 works, i have tried that...
let it go and return to stock.Honestly when the source-code for harware is not open source , no custom rom will be ok on the long run, is just change . change and change..and seeing how easy it is to brick this device , in my oppinion is doesnt worth the trouble.

Hi!
Really need your help
I flashed my phone and sold it.
Now customer claimed no network connection and sent it back.
Today I checked the phone and saw, that no IMEI were present.
I restored the IMEI, but there is no network connection.
I flashed the OEM ZTE image and have no clue what else could help.
Any idea?
Is this maybe MODEM related?

I would try reflashing the modem, making sure you're using the latest twrp 3.1.1 and that system is mounted before flashing.

I sometimes get problems just after flashing, and GSM/Wifi 5Ghz take up to 5 minutes to initialize. Deactivating and reactivating the sim card helps. Did u try that?
- Else, I'd get a 7.1.1 factory image and start over, that baseband is *exactly* the same as mine and I only have that "5-minutes-without-wifi-and-network" bug.
- Try looking for wifi just after booting the phone : if you only see 2.4Ghz networks and no 5Ghz network, just turn the sim car off and on, and it's ok, just that bug.
reflash a full stock firmware, if you have imei, you must have then, then if you want, do the process again to get twrp
Hi Folks,
i've done some reading and my problem is a broken EFS sector due to TWRP recovery.
Even after manual IMEI restore, the EFS is broken and causes the no service issue:
https://forum.xda-developers.com/axon-7/how-to/investigation-recovering-efs-twrp-t3522171
Only option is to get a EFS copy from another device, push it on my one and change the IMEI to my own manually.
If efs was ’restored’ using the signed twrp used for unlocking then there is no fix for that.
I have flash RR remix ,and its works perfectly,its great custom rom ,for me is very nice and smooth, but after rooting with Magisk ,I have problem with GSM network, also I notice that I loose and IMEI number..
Can I somehow fix IMEI number without PC and bring back network signal..

I don't know what's gone wrong with his IMEI but it doesn't mean his EFS is deleted like the guy in that thread.
@jjoeshua check your root directory. Do you have a folder called EFS?

I found on XDA guide how to fix Imei problem with Imei repair program and make a flash Imei file that I install through TWRP recovery and its not fix the problem but its a little better, when I. Turn on my phone ,I don't have GSM network but after restarting one or two times the network is back. It not stable but most of the time I have GSM network.
Do you have any idea what causing this problem, I don't have this problem with superSU only with Magisk,
