Hi,
I have a n9200 Chinese version of the note 5.
I recently tried to flash a custom ROM on the device because I wanted to try nougat, but seems like most of the stable ROMs don't boot on the n9200 or something not working (2nd sim slot e.g.).
I decided to do a restore in TWRP of my stock rom.
However, the SIMcard isn't detected anymore.
"Insert SIM card" message appears if try to click on 'mobile data'.
I did a full restore of the rom, including radio, so shouldn't everything be as before?
I did also try to flash other ROMs, but the problem remains..
Do You have any advise of what to do?
Is it worth trying to flash the modem in Odin?
I assumed that it restores the modem if I do I restore of the radio in TWRP.
Ok. So I have done some research, and I came up with two possible causes to this problem..
1) I bought my phone (n9200) region unlocked, could the lock have been reactivated when I loaded a new rom?
2) I did a back up of my stock /efs partition before flashing anything.
However, I cannot find any .nv_data.bin in the efs folder... Could this be a problem? Are there phones without this file?
Would be grateful for any help. I have tried flashing different stock firmwares through odin, but the problem remains...
You should try ODIN flashing the stock firmware you were using when you first flashed TWRP. Bringing it back completely to stock including the stock recovery might set things straight. If this does not work you might need the PIT file for your device for flashing in ODIN. Best of luck.
Download the latest firmware for your device and flash it via the latest version of Odin. I had a similar issue where I flashed a custom ROM and lost service completely. I simply flashed back to complete stock. I got my stock firmware from sammobile, may take you a while but it'll be worth it cause you can then keep that file and always have a stock backup handy. Do it all the time.
Help plz

Did any one fix this problem???
Yeah, I actually solved it
It never worked to restore with Odin. SIM card was never recognized.
I did however download an official Samsung application (think it was smart switch).
I could do a factory restore of my n9200 through that application and its fixed the "no SIM issue".
i hope it will work for you too.

Hi,
Recently I tried to clean flash AOKP on my stock rom using twrp 3.0.2.X, after flashing when i boot up the device it wasnt detecting sim card and the device's IMEI, SN, BT/WIFI/MAC/IP address are unavailable, I manually tried to restore IMEI using this guide but the device cant detect sim card in custom roms like CM/AOKP/MOKEE but when i revert to stock kitkat rom it works fine and I just have NVRAM Error in wifi available wifi list. Please help me resolve this issue. Thanks in advance :fingers-crossed:
Flash stock rom using sp tool
Hello guys!
Six months ago I bought a used note 8 SM N950F once I tried to install another rom (custom one) after backing up the whole mobile by twrp, after installing the rom, the phone couldn't detect sim cards and imei, when I returned to the backed up rom everything were fine.
I searched for my phone's imei and the result was these imei numbers belong to another samsung device, samsung ace I think.
What is the problem? I can't use any rom exept the original stock rom which already installed to this device, help me finding a solution to install another roms with working sim cards.
Which ROM u tried? And also did u make a backup of efs?

Could I make an EFS back up and use this back up for the other rom?
Yes i think it can be done
... Quite a few tutorials to do that online. Go ahead and Google it.... I have not done it myself. So i will not be held responsible if anything goes wrong. But it should work. All the best.

SM-N950F
N950FXXUZDSH1
The stock rom which installed seems to be "claro"
but I have claro sim app installed on my phone
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 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?
