BTW you should post in Galaxy Note 2 Q&A forum ( use xda device search engine to locate it)
A modem change might give you results only after you have checked your APN ,
Quick Guide
First Check your settings > about phone > status > your phone number ( IF UNKNOWN )
You won't be able to send SMS by any third party sms apps or Have a Network connection
Solution :-
You need to edit that "unknown" number to your phone number, by putting your SIM card on any old phone that has a "my number/owner number" option, (most old phones do). Edit and save it to the proper phone format as your Sim Card number (Example: +63913XXXXXXX). Now put the SIM back to M110S, to solve this problem.
Than check your system settings, in Settings > Wireless & Networks > Mobile Networks > Access Point Names.(APN) as provided by your Network provider . If your Apn is not set, you wont be able to have data connection, so set it first
If still no data connection, Common Trick is to toggle WIFI and Airplane mode or
1. Turn ON WIFI
2. Set the phone to Flight Mode
3. Power down the phone for a few Minutes
4. Power it back up
5. Turn OFF flight mode
6. Turn OFF WIFI
Should get Data back

[Q] Galaxy nexus efs lost

Hi,
I had an OTA update from 4.2.2 to 4.3 and some days after that, when I was using google maps while on roaming network, my phone stopped getting signal from carrier. Since then, I have followed many posts on xda and did these things using NRT (Nexus Root Toolkit):-
1. Unlock
2. Flash + Unroot
But, after doing all these, my phone still does not get the signal. The current problem (I'm not a very technical person):-
1. About Phone --> Status (copying only those properties which might be relevant):-
Network: Unknown
Signal strenght: 0 dBm 99asu
Mobile network type: UNKNOWN:0
Service state: Out of service or Radio Off (this keeps on toggling every few seconds)
IMEI: UNKNOWN
IMEI SV: UNKNOWN
Serial Number: <some number>
2. Phone info available in *#*#4636#*#*:-
Set preferred network type: Unknown
Turn On Radio or Turn Off Radio (This keeps toggling every few seconds)
Actually, after reading so many posts on xda, I can conclude that the efs partition is lost. If I'm goig in the right direction to pin point the problem, please let me know where I can download EFS and change it to point it to my Phone's IMEI.
Will the above step solve this problem ?
Any help is much appreciated.

If you have a Nandroid Backup, just restore it. Ur signal will be back.
If ur EFS is gone, U'll have to do one more step. This thread might help you. I had the same problem (IMEI lost) and fixed my phone by doing this http://forum.xda-developers.com/showpost.php?p=47045295&postcount=6

Actually, I don't have a Nandroid backup.
And, the steps mentioned in the link you provided also do Not tell about how to fix an unknown IMEI
PS: I dont have a generic IMEI now. My IMEI as seen from *#06# is empty. *#06# shows IMEI (but no IMEI number next to it) and then an OK button.

[help] network problem - imei Matter - imei NG

Hi
So I bought this phone used.
I put sim card .. the phone shows the Carrier, even shows the APN settings . But I can't make calls (emergency calls only)
The imie of the device found on back is For Factory Unlocked 928A and I contacted ATT and confirm it's unlocked.
The Problem is : when you dial *# 06 # the phone shows a different imei number. And this particular number when looked up doesn't belong to any device on Earth. Using imei checker. And when going to service mode it shows imei: NG
So.
The first step on solution is to restore the original imei number that belongs to the device . That's logic right ?
How can I?
What about efs partition ?
I am on latest Nougat. Can't downgrade to 5.1.1 to root and try to change imei or restore efs
Trying downgrade in Odin give FAIL lol
What to do ? Excuse my English.

*ISSUE* How to restore IMEI (SM-G532G) Galaxy J2 Prime

Hi. I tried to change my IMEI number using the Chamelephon app. It did work, but it didn't turn out great. Network functions are okay, but it needs constant network operator scan as soon as I turn on airplane mode or restart my phone. The IMEI number became random numbers and symbols.
IMEI 1: >8<4=<:7?7<6?:2
IMEI 2: 9><398?64><6086
EFS is fine. Only IMEI has a defect.
I realized that Chamelephon should only be used on MTK (chinese or cloned) devices. Now I can't seem to find a way to get it back. Can someone teach me how, and do I need to get any Samsung Tool Pro type of things? If yes, how do I get started? (btw I want to do this for free)
