I broke my G920F modem and EFS. Going through the threads I found somewhere it said I should make a backup and restore it. If I restore a backup I made after breaking it, only one SIM card works in the phone. Any other SIM card says "No SIM card" but when I remove the SIM tray the phone prompts for a restart.
Flashing stock firmware causes the phone to lose IMEI and it won't connect to mobile networks. It can, however, detect the SIM card. Once I restore the EFS/IMEI folder it reverts to not detecting SIM cards.
If someone can provide a solution to this problem? Or if you could provide a TWRP modem/efs/radio backup that I can restore onto the phone via recovery.
Currently running Android 7

Please help me out! So I previously had PA running on my Nexus 5, no problem whatsoever. Then, just recently my phone did not detect my sim card. I tried restoring my old nandroid backup, flashed multiple ROMs, and even restore the phone back to stock, still no progress. I have also tried my brother sim card but still it would not detect. One thing that is major problem is with the stock lollipop update the "cellular network settings" is blank out, so I can't even access the APN setting to input Tmo setting, even with a working sim card in the phone. Could this be a sign that it is a hardware problem and not a software one?
Thank you.
After flashing an international stock firmware on a chinese phone I've lost Imei and band so the phone can do anything but detecting my sim card.
The firmware was flashed via bootloader.
Is there something I can do? Are there possibilities that I've lost the EFS folder and the phone is gone?
Well i no longer have the correct imei for my phone so no sim cards work with it anymore is there anyway i can restore it?
So, I flashed a custom rom and lost my both IMEI numbers in settings. Due to which i'm unable to use my SIM card. I can't seem to roll back to stock software as it gives an error inbetween flashing.
Right now i'm stuck with LiteROM.
Thankfully, I still have the IMEI numbers from the S7 box. Is there a way I can restore them back to phone so i'm able to use my SIM card again?
Help is appreciated.
EDIT: So I noticed I have a EFS_Backup from August 2020 in my storage with .tar.gz file extension. Is there any way I can restore that?
EDIT 2: fixed by flashing the Dev ROM
I have rooted my phone (A315G XSA) previously with magisk, it was using an android 11 firmware version, now that android 12 has released in my region I have tried to flash the stock files using odin, after it is done it allows me to set up normally but as soon as I end a call it will no longer detect either of the SIM cards.
I have tried NAND erase and a pit remap but they have not helped at all.
Factory resetting the phone after it no longer detects the sim allows it to make or receive one call
Backing up the efs and the sec_efs partitions and then restoring them after the sim cannot be found does not work either
