If you have restored the backup properly, just try to factory reset the firmware...
Which method you had used to backup and restore EFS?

I did not have EFS backup so I used SRS unlock client with UART cable to bring back the original IMEI, now my IMEI and S/N is correct but phone still wont register on network. Any ideas?

I am having the same issue after having flashed the 4.3 version found on Sammobile. SN and IMEI are correct. Have you found a solution?

Please help me too , same situation
previously worked with dlk6 or dll6 firmware/modem on 4.1.2
When I flashed 4.3 Xperia-z1-ized ROM . Device showed correct imei and MK1 modem from the ROM but says "not registered in network "
Have no Idea what went wrong. I have no backup of any EFS or anything .
I installed emergency firmware upgrade via Kies and now running stock 4.3 Android UBUEMJ4 Modem , build number : MK4 Status : offical.
I don't even know if i can root my device with current stock firmware.

[Q] no service

hello all xda members
my phone's charging chip got damaged so i got to the service centre, they said my motherboard have to be replaced so i got it replaced i got my phone back rooted like before but with 4.1.1 so i updated it to 4.4.2 n flashed jellykat rom but soon after that i got no service error sim is getting recognised but a message pops up that selected network (any network tried different sims ) not available
again i went to service centre he took the phone for one day n after that i got network back but soon after i flashed another rom (clean installation) the problem came back again
i browsed and got a temporary solution of flashing mj9 patched modem but due to this modem my wifi signals have become terrible not even able to send a whatsapp message

Best thing to do is to install stock latest 4.4.2 INU firmware via Odin.

Samsung Galaxy Note 2 7100N Network problem

bump please help

Does the phone show the correct imei? Could the phone be blacklisted? Model in download mode is n7100? How did you update to 4.4.2?

Download and install MobileOdin, copy stock 4.3 on your device then install ROM from device.

I know nothing about IMEI,i update it with Odin.

If the phone does not have the correct imei #, it will not connect to a carrier network.

check your IMEI by typing in the dialing screen *#06# and see if its start at 0499 or its on Null/Invalid
i had a similar problem which i updated from 4.1.2 to 4.2.2
the IMEI was correct but it still was stuck on emergency call only
i found this modem file which helped me.
i tried flashing all kind of roms with this modem but it was pointless..
until i tried flashing that Omega v4.2.2 rom and then flashed the modem again
and it actually worked..no clue how did it work on the Omega and not for the others but oh well..
now im on CyanogenMod 5.1.1 and the phone is fully working.
If you planning on doing something like that (messing with your phone rom and such..) dont forget to make a FULL backup.

I had similar problem and worked fine..download 4.3 or 4.4.2 from Sammobile stock XEO Poland or XEF France ROM. They have modem we in Croatia use. Problem is not in ROM then in your modem or your device is locked on one carier but you have wrong different carier SIM.
Or just look here for modems then flash it with Odin but over computer.In ODIN check "nand erase all".
Of course you need to wipe everything ,flash ROM then flash modem separatly but it MUST BE XEO or XEF modem !

Question Sim won’t register on network - based in Australia (Fold v SM-F926B)

Need some help guys. I am based in Australia and swapped an iPhone for the Z Fold 3. Went through the usual connection process with my sim and esim whilst connected to wifi. All was well as it allowed calls and received calls when I was home. As soon as I stepped outside my home where it was trying to use the network, it does not work. It keeps saying not registered on network. Tried to manually select network via settings, checked all APN settings from the network and all is ok. Even tried 3 different carrier sims (Vodafone, Optus and Telstra) yet still no matter what this phone will never connect to any carrier network without wifi. From there I tried 3 different firmwares from Sam mobile just in case it had corrupt firmware. Both android 11 and 12 will not work. Need help guys please. Any suggestions?

Two options
1. Get into recovery and do a factory reset
2. Flash the latest firmware ( F926BXXS1BVB3 ) , firmwares are now Multiregion so no problem with that

If that doesn't work , maybe you lost your EFS partition ( it contains your IMEI info ) and that is a big problem
You will have to read a lot here @ xda to try to recover it ( if it'spossible somehow )

Thank you kindly for the information and reply as it is really appreciated.
I can see both imei numbers on the device if this is what you mean? Ironically when the phone is on WiFi with WiFi calling enabled and the simcard plugged in, it allows me to make calls with my number sending to the recipient, it just won't do the same when the WiFi is disabled, I can not communicate out by data nor voice and it keeps saying "not registered on network." I have checked and the phone is not network locked and is clear for use. I will try the firmware link you have sent however if this does not work, may I ask what you think may be next?

To add I have tried various firmware which did not work either.

Can anyone help with this as the above unfortunately did not work.

When you flashed stock firmware , did you use CSC or HOME_CSC ?
You have to use CSC , to get a fresh install
If possible , once flashed get into recovery to perform a Factory reset from there , maybe this can get back the EFS partition that seems to be corrupted
again ... DON'T use HOME_CSC

Thank you for your reply. I did use csc and followed all your instructions. Unfortunately still the same. I am so lost as to what to do as I love the phone but can not seem to fix it.
