Hi, Installed a custom rom but it didn't detect my sim so i flashed a 6.0 EU modem but i forgot to backup... I tried installing other ROMS but no sim on either of them which has worked before. So i flashed the out of the box stock firmware through adb and reset everything but no sim detection on stock either... How do i get my connection back?

Here's my problem
Received brand new LG G2 F320S Korean variant. Have previously had Sony phones with unlocked bootloaders. Assumed LG would be the same.
Hated stock rom so rooted using ioroot, flashed TWRP and installed G3 port ROM
Inserted SIM card but phone wouldn't detect
Reflashed baseband thinking that would help, no luck.
Decided to revert to stock
Flashed the 4.2.2 KDZ - I was dumb and didn't notice it was 4.2 not 4.4
Still no sim card detected
Flashed 4.4.2 KDZ
Rooted and recovery now.
Still no SIM card detected.
The SIM itself is fine and I've tried another SIM with same problem.
The IMEI is showing up correct. Could I have killed the EFS partition when installing custom ROM? Would that mess with the SIM card detection?
Help please. Much appreciated

Any solusion forthis problem,i have the same problem
I have SM-G935S (SKTelecom Korea) and have been trying to improve battery life by using custom ROM. The installation is a success, but it makes my phone cannot use mobile data connection. I have been trying RENOVATE 4.0, SupermanROM, and KingROM but all have the same result. Are my device not compatible with those ROM or any mistake and fix that you can point it out to me? I'll be thankful for your help.
If the imei still intact, there's hope. Try flashing original rom. If not, service center is your only option.
Try updating Boot loader and Modem before installing the recent custom ROMs. Or use ROMs that have the Auto-Bootloader and Modem update. Check APN settings for Your network.
I have the same issue but for a G935F
Did you solve the problem?
It happened to me also. I have g935f. Only thing that works for me is to install csc after installing the rom. So first install rom then let it boot. after boot before settings go back to recovery and then install your csc and then boot up and do your settings. Good luck.
I reverted to the latest stock firmware from my region and carrier with odin and it doesn't even detect my sim card. I tried restoring radio and efs from a previous rom I had, but it still doesn't work. I even had to manually flash the csc files because they didn't exist. It still shows "baseband unknown".
Try flashing Custom rom
Sorry for my English, but I'm Panamanian ... I have an S7 that I installed RROS and now the phone does not detect the SIM card, and I need the libsec-ril.so file to fix it. Can you help me?
Go to stock rom via odin and then your sim will work fine .After that make a backup of efs and then after Installing your custom rom you can just restore that backup and sim will work fine..

That's the problem, and that is that my phone does not allow the installation of Rom Stock, because I bricked my phone, But currently it only works with Custom Roms
I've got an sm-g900t running RR O 8.1.0 custom rom. I got a sim unlock code so I restored the stock rom. I successfully unlocked the sim. Then after restoring back to my custom rom, the sim is no longer unlocked.
I've read that this shouldn't be happening but yet it is. Is there a trick specific to the S5? Do I need to reflash the RR rom and start fresh? I hope there's a better way so I don't have to go through getting my settings back to how I like them.
Thanks for any insight.
Update: I restored back to stock, unlocked the sim again, then made a backup of the EFS, and finished by restoring all but the EFS of my RR custom rom. Success - I'm right back where I was and still have my sim unlocked.
