Have you checked all of your network settings?
Have you tried searching to find if there is a secret dialer menu to control your radio settings?

I customized my room to Liquid smooth, then I did factory reset.. after that, my phone is now having NO SIGNAL but the carrier is there. The IMEI showed as 004999010640000 ( i think nulled). I tried my sim with another phone and it's working.
I tried some options with FTM OFF but it's unknown command. I tried factory reset again and it's still no signal. I tried default APN but still no signal. Airplane mode is OFF. I tried searching network operators to automatically choose but still no signal.
How can I fix my Galaxy note 2 (international)? or return back to stock ROM or restore original IMEI? Please help. Thanks

Hello,
My phone: GSMART Roma R2 (Rooted)
I know there are a lot of threads how to restore IMEI but none of them worked when I dial up *#06#, it shows message with two lines containing "null".
I was using MIUI rom for a while and suddenly after I rebooted phone SIM was no longer recognized (before reboot I was playing with SWAP couldn't make it work so I uninstalled BusyBox (could that cause the issue?))
I already tried:
Engineering Mode: Displays "AT command is failed to send"
Terminal Emulator: Doesn't work
MAUI 3G: Flashing new IMEI changed nothing.
MTK Droid Tool - Changing IMEI did nothing.
SN Writer: Writing new IMEI changed nothing BUT when I choosed to read IMEI it successfully displayed both IMEI in the textbox. (So it looks like the IMEI actually is registered on the phone but phone doesn't seem to use it)
Manually writing MP0B_001 to NVRAM: Nothing changed.
I have used backup in CWM recovery to stock ROM, didn't work, then I did factory reset, didn't work, flashed back the stock recovery and installed update from Gigabyte site, didn't work. So basicly now my phone has stock rom, stock recovery, factory reseted and is rooted.
Thank you very much for any answers because I just fell hopeless about fixing my phone
Hi there,
I see you already posted new thread in the right place: [Q] IMEI null and SIM not recognized, nothing works
Please wait an answer there.
Thanks, thread closed.
I already repaired IMEI (dual) and already connected to my WIFI but still, NVRAM error is showing. Even though i can access the internet (browser/youtube) using my oppo f3. And also IMEI SV is unknown.
Another question (??hardware??)
*note: after flashing stock rom
1. Figher print/home button not working anymore
2. Battery connection error shows up
