Hello everyone!
I am new to custom ROM flashing. I got a Samsung Note 8 N950N (korean model - I guess) - but it shows N950F in Settings app. I got a used phone from someone, and they had installed some custom ROM on it.
Now, I flashed LineageOS 17.1 on it, everything is working smoothly so far but my mobile network isn't working. I can't make or receive calls. The phone is showing "Emergency Calls Only" - but showing the network name, and I can also access the SIM card toolkit inside the phone.
I tried clearing cache and everything but can't seem to make it work. I tried using the manual cellular search, but it says couldn't find any network.
It is a dual sim phone, I had 2 IMEI appearing on earlier ROM, but now with LineageOS 17.1 - I am only getting 1 IMEI as well.
Update: I restored to the OLD ROM (LamLazy Rom v3 Dual SIM) - and the network is now working back on the phone. I don't know why it wasn't working on LineageOS 17.1, can someone please help?
Did you manage to get a custom working with cell service too?

Hi,
I recently installed CM11 (final official snapshot) to my stock rom slot (I had it on rom slot 1 before, but changed to stock because it is a lot faster). Everything seems to work, but the SIM is not recognized anymore. Calls, SMS and Data (2G and 3G, since I am in Europe, 4G does not work anyways) work fine.
The lockscreen says "No SIM Card, Emergency calls only" (or something like this, I am translating this). The signal strength is always reported as 0% or -120 dBm, even though the signal is fine.
When I go to Phone Status, it tells me that my phone number, MIN, PRL-Version and Serial Number are unknown.
Network Cell Info Lite tells me that "SIM Status" is unknown and that it can't read any info from the SIM, but connectivity is fine.
On the old installation everything was fine.
I tried all the usual things (rebooting, reinserting the SIM, ...)
Does anyone know what could be the cause?
Edit: SMS is not working. And a factory reset did not help.

you installed over the stock rom on the stock slot instead of another slot am I correct. Also witch version of ss are you using.
Ok, I finally had some time to test a bit more. I am using Safestrap 3.75. The problem also exists if I install the ROM (tested with the newest two official snapshots) to a clean regular ROM-slot (I used slot 2). It does not exist, when I load the old installation that I have on slot 1, which is based on some old version from mid-2014. So it does not seem to have anything to do with the slot or the phone. I will be trying other versions.
Guys, who can help?
Bought a MI5 from China (I'm brazilian), updated to MiUI 9 then suddenly it stopped working both Sims.
Sim 2 doesn't connect no matter what I do. Sims recognizes carrier but zero signal and only LTE (as screenshot). When I try to call some, it says that it's not possible. Details: Sim1 only get LTE if I'm connected to Wi-Fi, otherwise it's no service as sim2.
Did research here and
> Both IMEIs are working, appearing in *#06* and are the same on the box
> Gone to carrier and there's NO imei block
> Tried to flash, downgrade, upgrade from to every version available in the MiUI download section (tried China too, no sucess)
> Did hard reset
> Flashed only modem files from a stable room (tried with dev too)
> Tried *#*#4636#* options, leaving Sim1 as LTE/WCDMA and Sim2 WCDMA preferred and nothing
> Tried too to restore efs partition but I did not had a backup so I don't think it's gonna work. And I don't think thats the problem too once both imeis appear and baseband OK.
Used QPST but it didn't worked
I don't know what to do anymore. Can you guys give some light?
Thanks in advance
I would post imgs but I'm new user and can't,

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:

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.
