I've read through multiple threads on this site and many others to try to find a solution to my problem. I have a n900t stock rom, carrier unlocked that i have been using with straight talk/AT&T service since december of 2013. Well as of a month ago I updated my apps as i always did per the phones notifications and my signal started to just disappear. It has gotten to the point that the signal has permanently gone as i would get the message everytime i go to place a call "Not registered on Network". So i was told by the local phone repair techs to update my phone to the lastest firmwire, which took me from 4.3 to 5.0 and still no signal at all. It's not my sim card as i have a backup at&t phone which i currently have the sim card in now getting a strong signal but my note 3 is without a signal with the peace symbol in its place. My baseband is NB4 and my Imei is still there as i don't have a null imei and if it helps when I dial *#0011# it yields:
No Service
NETWORK: UNBLOCK
IMEI Certi: PASS
Can you please help me and tell me what's going on and how i can get my phone to function again?!?!? thank you in advance!!
Can anyone help me? I've been reading post and doing my homework on this site for the last 3 weeks before I made a post and I've come to the end of the road, I've run out of research and I believe someone on here can help me. Please help me!

HELP! 4g LOST / not working
THE SHORT OF IT: I flashed a custom ROM & kernel. They didn't work properly, so I flashed my nandroid to get back to rooted stock. NOW I HAVE NO 4G or signal of any kind (wifi works)!!!!!!
THE LONG OF IT:I'm in South Korea using the Galaxy Note 2 on the carrier LG with their U+ LTE service. As far as I could see and have been told my phone ONLY uses 4g (no 3g or other options to check). I was advised to flash a Tmobile or ATT Rom (I chose the Tmobile AOKP) as our U+ phones don't have their own Roms & Forums and I flashed a custom kernel from sjkoon a developer posting kernels that work for our phone. Others have done the same thing and reported no problems. After flashing, the new Rom & kernel, the phone booted in the Google startup helper I could not gain access to any signal or wifi to access or create a gmail account.
So, I nandroided back to stock (rooted, mind you, using chainfire's exynos exploit) but my 4g won't work, only wifi does. So, I have NO way to make/receive calls. I've verified a number of pieces of information through various avenues and have the following:
PHONE INFO
My Access Point Names says "LG U+" with "internet.lguplus.co.kr" underneath. There is no option to change it or edit it, just a radio button with no other options (is this is fine?). I was advised in another forum (http://forum.xda-developers.com/showthread.php?p=36895160#post36895160) to change mmsc's value to http://omammsc.uplus.co.kr:9084, but I dont' know where that option is to change it, or if this is a problem.
I also used the the "Phone Info" app and got some of these readings:
In Telephony, have a Device ID, my Network type is 3, Sim State 5, it shows I have a SIM operator and country, Serial Number Subscriber ID, etc. The only things that MAY be strange (I don't know what their original values should be) are that Call State, Data Activity and Data State are all 0 and my Network Operator Name, Network Operator and Network Country ISO are just blank. Even if I wanted to change any of these I have no idea how...
PLEASE HELP & THANK YOU!
It's strange. I spent the night/morning searching forums for a solution but not sure exactly what to do. Please, help me or point the way to fix this issue if you know how and thank you very much. I'm willing to buy you a beer or buy your newest app, say thanks on all your posts for the next month, whatever! Hehe. ...:crying:
HI Team,
Recently I have rooted my Note 2, It was good . But after that I installed SLIM ROM 4.2.2 version on my phone where i started facing problems...
first of all, I didnt recieved any incoming calls...
later after i unrooted the phone.
Went to service center installed latest version of 4.12 official. But no use . I am unable to get signal on phone...
The thing is can search networks but unable to register on the network. Can you guys help me with this regard...???
Has your IMEI been lost?
What does *#06# show you, does it match the IMEI on the back of the phone (please, don't post your IMEI here)
I wanted to unlock my note 2, it was on 4.1.2 so i decided lets downgrade to 4.1.1 and unlock it. I used the sasktel stock rom to downgrade it and it succesfully downgrade and used the free method to unlock it (*#197328640#). Now, for some reason whenever i put simcard it gives me Emergency calls only 9laready checked the simcard, its working fine, however when i try to put my old inactivated rogers simcard it does tell me unregistered simcard). Please help...
So far i tried to put bell stock firmware but no luck, didnt make any backup for efs or anything (i already tried the same thing on s3 and it worked fine so i thought it will be same thing)
Please help me
Just want to add few things, i install original stock rom through odin bootloader instead of pda. I do get the signal from my simcard if i turned my phone for few hours and turned on but when i restart i do get the same error emergency calls only. Please someone should help me here, i dont mind making a donation to any developer whoever can help me...
Can somebody help me here and atleast guide me. Should i basically call Samsung and get it replaced, its still under warranty?
Does it say emergency calls only or no sim?
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
i have the same problem when i tried to unlocked with z3x, i correct all issues , imei, base-band , .. the cell looks perfect just Emergency Calls Only on bell Note 2 i317m, i tried a lot of tricks but didn't work i think it's network security part problem? any one have an idea ?
hello everyone, my friend got this phone and he was using all the time the 2G network. i am from greece, when i got the phone i saw that there was no 3g network. the phone was getting only 2g network. when i checked the imei i wsaw that it had the format 0 /01, i tried to fix it with any solutions but i couldnt, the phone was not even rooted before. i rooted it. tried lots of things but couldnt manage to fix anything.
if anyone knows how to restore the imei please tell me.
If you previous don't have a back-up, you're screwed. You need a special tool box to insert the IMEI back. As the phone progress, it becoming increasingly hard to restore IMEI by just ADB. Plus its against forum rule.

use this app its free in play store his names mobile unkle mtk tools and write the imei from the engenier mode manually
I'll try to be brief. lol .Before finding this site I brought my unlocked S4 mini to wind to see if it will work. The guy found the 1700 freq in the phone service menu and changed something and said it won't keep on 1700 then he said something about the nv write. After a while he handed it back and said it wouldn't work. I put my bell sim in afterward it said no sim. it won't find any bell sim now. I tried a friends telus sim and it finds the sim fine and shows voicemail notifications but when I tried to call it says not connected to network. I can see the networks but when trying to connect, the signal drops and phone says "network not available try later". After it tries to connect the signal returns to normal.
So I found this site
I successfully rooted the phone with S4Mini_RootKit_v2.zip. It worked fine but had the same network problem. I fully rooted with cm11, then 12. Same problem.
I loaded a pit file gotten gaciously from sammobile. Same problem
I've returned all firmware to factory and undone root but still same issue.
The imei and serial number match the sticker on the back so they are not invalid.
The wifi and bluetooth and general operations are normal.
I'm guessing that the nv was rewritten and to recovery as well? But I really don't know as I am very new at this but have been doing a lot of reading.
1. Is there a way to restore the nv without a backup from my phone?
2. Is there a way to restore the service programming back to factory default? (I've seen this question asked before but only found the answer it is proprietory, whatever that means)
I have qpst and efs professional and a qcn file I was able to download from the internet
3. This qcn file is from unreliable source. Could I damage my phone more than it already is, and can i edit my imei and sn into it?
Thanks very much.
