I am new to Android Custom ROM and everything. I got this phone from a local vendor and it was running a custom rom called "LamLazy Rom v3.0 Dual SIM" - I researched on it and figured it was used to convert N950N to N950F or something like that.
I have the EFS and TWRP complete backup of the LamLazy ROM. I wanted to try LineageOS 17.1 on my device and flashed it using TWRP. After the successful flashing, I noticed my phone can no longer connect with my network. I cannot make or receive phone calls. I tried every possible thing that I knew. Even flashed series of Custom ROMs, on every other rom I faced the same network issue.
However, when I revert back to LamLazy it works fine. I can use both of my SIM slots and my phone shows 2 IMEI's while on lineage and other it shows only one IMEI.
Now, my problem is I want to get rid of LamLazy and try new ROMs such as Pixel Experience and LineageOS, but my cellular network doesn't work. Can someone please help me with this? :crying:

After flashing 610M (csc: TPA) the phone shows "No sim - No service", even tough in sim card management it's there but no carrier is shown.
I tired:
1. IMEIs were there, but I still tried to restore EFS
2. Tried both sim card slots (the second one can at least receive messages, rather weird thing)
3. I tried to flash CP and CSC trough Odin after installation
4. CSC Changers do not work: errors
5. Tried to install similar ROMS: ResurectionRemix, AospExtended and crDroid... same problem over and over
6. Tried flashing latest Oxygen kernel v.5 - no luck
7. Tried installing without GAPPS - no change
8. Tried flashing latest modem from 8.1 official - nothing
Please, help me good people, I'm out of ideas. Currently using Millennium ROM, everything works. No possibility to buy a new phone, but I miss the simplicity and snappiness of AOSP roms. Thank you.
EDIT1:
I found out that even after flashing CSC in Odin. PhoneInfo app shows that there's not CSC or CSC firmware at all. Attached screenshot.
Have you tried checking if your IMEI numbers are blocked in your country?. Could be blacklisted by an operator.
From which state you are probably problem in restricting the device

I use Millennium ROM (which is non-AOSP) right now, and cell service works perfectly. I can try checking of course (will reply later).

Weird, I have the same model as you and I've flashed a few AOSP roms (Havoc OS, DotOS) and no problems with my signal.
Well, if it works in TW, then it could be the radio firmware in the AOSP roms that is causing the problem with your signal. Im not sure how you can flash the radio firmware once you are in an AOSP rom, but you could try making a backup of the radio related partitions with the Millenium ROM installed and then try to flash the backups once you flash an AOSP rom.
Make a full backup just in case something goes wrong.

Thanks for the reply. I did try to restore EFS and Modem partitions after flashing DotOS, but no luck. I looked at the *#*#4636#*#* menu; and there's a signal (decibels change). It's like it doesn't read SIM cards (I've tried another one with different carrier).
Hello
I need help, some days I tried to install a GSI ROM on my XT1944-3 however it never booted up, after returning back to my previous backup I noticed that the sim isn't recognized by the phone, at this point I tried reinstalling the firmware, even I tried flashing the NON-HLOS from the dual sim variants without success
As you can see in the screenshot that I attached also I lost other numbers
Also I checked the IMEI on blacklist and it's clean
I don't know if someone else faced this before and could solve it, please help me

If you are still having issues, you probably just need to re-install firmware, then OTA updates and that should restore the sim.
Do you know the IMEI numbers ? Then it's easy with Code *#6813# insert and press ok
-i have also problem with imei i installed
[ROM][10.0.0_r41]LineageOS 17.1 for Moto E5 (nora) + Recovery [64Bit] mmoto e5 work fine imei is restored
I flashed Havoc OS 3.12 (Android 10) on my Galaxy A30 (SM-A305N).
(What I used: https://www.recovery-mode.com/custo...ficial-android-10-for-samsung-galaxy-a30.html)
Everything worked properly, including mobile data.
But I found that I cannot make calls nor send messages in the rom.
I checked in the Settings app and found that the SIM was installed properly, as mobile data was working
and I could see my phone number.
Can anyone help me fix this?
My country/carrier is LG Uplus (LUC), Korean model
Also, will it damage my device if I constantly switch to Havoc OS and stock rom with TWRP restore method?
Please help me.

Can you check your IMEI (Settings - About phone)? Hope that is not "null".
If yes, your IMEI is corrupt and has to get repaired/restored.
If no, then try to re-flash the rom again, and test with another SIM card.
I have tried many custom roms but when i flash it, my imei number becomes unknown and i can't use my wifi and my sim is not detected. I tried and followed every steps but it happened every time. Then when i used the motorola rescue tool and flashed my own firmware i got my imei number back and sim and wifi are also working. I want to use a custom rom, which custom rom should i use?

I tried with leveno app and I can back it up, but still got null baseband not found. I know I asked from you a lot but is there anyway backup EFS and presit (sorry my spelling) into an twrp backup?
Because even I flash the stockrom, it dosent find IMEI numbers and the carrier
Hi,
I hope you could help me.
I have Samsung Note 8 SM-950N and I am unable to make any calls after flashing stock ROM.
When I received it I checked the model first and it showed SM-N950N in the download mode and SM-950F/DS in the menu. That seemed weird but after reading a bit I concluded that one in the download mode is more accurate so I downloaded and flashed SM-N950N_SKC_N950NKSU5DUG1 ROM. Now I can't make any calls and IMEI has changed and it turned into single SIM phone.
I would like to restore the phone to its original state and have a call functionality. Maybe you could help me.
I have attached pictures that I made before flashing.
After flashing stock ROM it looks like this.
What happens if you decide to flash back to n950f rom?

I think initially phone came as N950N, but someone tried to make it dual SIM N950F/DS. If I try to flash N950F stock ROM SM-N950F_SEE_N950FXXS5DSC6 it fails in Odin.
When it was converted to dual SIM network was working I have taken a screenshot of IMEIs as well but I wanted to revert it to stock. Now it shows single IMEI even though when I enter this IMEI online it says it can't find it.
I even removed the back cover to check IMEI number on the battery but it is different there as well (it might be that the battery has been replaced?).
