Try flashing a different modem.
You can download stock firmware from www.sammobile.com and extract out whichever modem you need. Flash it via oden.
Or look at the Note 4 subforums for a list of individual modems posted.

[XXLPT] Can't Detect Indonesian SIM Card Al

Hi all,
I have a problem here. I've got a Galaxy Note from USA but I'm Indonesian. When I insert any Indonesian SIM Card, my GN won't recognized them.
I've tried to flash N7000DXLSE N7000OLBLSE (Indonesia) but didn't work. It make another issue, baseband on "about phone" show "unknown" and my GN still can't recognized Indonesian SIM Card.
So what should I do to solve this problem?
Any help will be appreciated, thanks.
NB: Sorry for my bad English.
Is it a new N7000? Are Sim cards from USA working? Where did you buy it and why not ask the seller?
Please try to change the sim pin in your settings (you can try to use the old one as new one).
And tell us if your IMEI number (in Settings, About device) starts with 004999... (please do not post your real IMEI here).

But I think you should read this and switch to the other forums.
USA note is not the same. Go look on their forum....

in other forums, doing factory reset after an install could result in a signal improvement..
but in case of GNote, you must make sure to have a non-bricking kernel to do a safe factory reset,,

maybe the phone is locked to US carriers like AT&T since it the unit came from US..
that is why your having trouble with network from Indonesia..
if this is the case try to unlock SIM restriction for global SIM cards..

though you flashed it with asian stock firmware, it may never be unlock by just doing so..

yeahh I think your Gnote is lock
I've encounter with the same problem with I9000 that I purchased from Romanian fellow. It was lock with their GSM carrier.
Just search for Gnote GSM unlock issue. You have to play with binary number to unlock it.

LG G2 VS980 not detecting/connecting to mobile network..

isnt the VS980 supposed to be unlocked for GSM use ?
I am in India at the moment...i have 3 Verizon G2 phones...SIM cards work fine on 2 of them...On the third one...it does not detect the mobile network...sim is detected ,coz it gives no alert...and when i search for networks...the networks are shown...it just doesnt connect to the network...the sim cards work fine in other phones...in the other G2 phones and in a HTC DROID DNA...so its not the sim at fault....
Have tried multiple SIM cards from Vodafone/Loop Mobile/Airtel...none of them work on this particular phone..
When i search for networks...im getting networks...but cant connect to them...most times it shows error while searching for network...
What can be the problem ?
Please help me out...otherwise will have to send the phone all the way back to USA...
if i am right... verizon phone is unlocked to all US carriers only....try to verify if its globally unlocked
EDGE/GSM (850/900/1800/1900), HSPA/UMTS (850/900/1900/2100)*
those are the frequence bands it support.
India support 900 1800
So technically it should work..
try *#06# to check if it shows imei number and other is to try to unlock phone

I got 3 Verizon g2... 2 of them work fine with Indian sim cards.
The third one is facing this problem.. I thought the IMEI was lost.. But IMEI is still intact and dame as that on the box.. Also Verizon g2 has no unlocking system as it is already unlocked..
That ink which u posted says it is unlocked for us carriers.. And not that it cannot be used outside the US.. People use it in UK, Australia.. Mexico.. Germany.. To name a few..
It seems the efs partition is corrupt but I don't know how to fix that as I have no backup..
Also if it wasent unlocked the sim won't be detected.
When I search for networks, the networks show.. It just doesn't connect..
The problem exists only in one of the 3 phones..
Ok then install custom rom and try with that.
I can recommend you for cloudy g3 rom. Best one out there
If your phone is not rooted and no custom recovery then open towelroot.com from your phone and install apk and it will root right a way
Then install rashr flash tool from play Market and install twrp recovery.
It's the easiest methods to install custom recovery and root I can recommend.
I hope this will work for you and don't forget to setup apn setting if data plan not working

I have a very similar problem. Using a SIM with 850 mhz HDSPA provider LG G2 works.
But when I use a SIM at 900 mhz, I got only voice. No 2G even.
Ideas?

Fixed for me. I rooted the phone. I installed the cloudy rom, based in the D802 version of LG G2, now, the phone works perfect. No issues at all.
I suggest change the rom and try other software.

does the phone have a big verizon logo in the back or in the screen? Then yes, it's a VS980. Pick that option in the aroma installer.

VS980 not picking LTE Frequency
I am from Pakistan and I have the same issue. Did anyone find any solution?
Ihave thisproblem too
I am using Verizon G2 32gb.. and yes... signal reception is so so soo poor.. at same locaiton, others handsets with same network are receiving very good signals while its on no network :/
Not picking any frequency or signal at all
Upgraded my VS980 to lolipop and after a couple of days same thing happened to me. I am in Pakistan btw. Sim is working fine on any other mobile. Have tried restoring to stock nothing happened. One thing i want to add is when i change my location sometimes for a couple of minutes, network do appear. But it does not makes call or uses data then it again gets to emergency calls only status... Phone is no better then i web browser now.... Help needed
Also not connecting (But it detects networks)
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/showthread.php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?

Which country? Is your phone a dual sim model? Please send full details of your phone.
No service error can be resolved by these following steps:
First of all make sure your phones Aeroplane mode is turned off
1) Reinsert your sim cards and restart
2) Factory Reset your phone
3) Use *#*#4636#*#* on your phones dialer and then select the phone information option, try to turn on the radio manually
4) If none of the above works please check the phone status by clicking about phone>Status>Sim1 or 2>Service Status, If your service status is showing Radio Off then you have to Reinstall The STOCK ROM on your phone or you have to flash only the MODEM Files of Original Stock Rom via mfastboot

I believe that you know how to connect your phone to your PC in adb fastboot mode, so i am skipping that part.
Please check you have downloaded "XT1068_TITAN_RETAILDSDS_6.0_MPB24.65-34_cid7_CFC.xml". This is Stock Rom Version of India.
If yes Please copy only NON-HLOS.bin and fsg.mbn files form that STOCK ROM zip into the installation folder of adb fastboot in your PC.
Once you connect your phone in bootloader to PC open mfastboot cmd and type and run only two commands mentioned below 1) mfastboot.exe flash modem NON-HLOS.bin
and
2) mfastboot.exe flash fsg fsg.mbn
Then exit cmd and restart your phone.
If any confusions you have please feel free to write down here. (regrets for replies may take longer, please be patient)
I hope this will surely solve your problem.
Don't forget to leave a reply if your problem get solved

If your phones IMEI showing correctly, then its only problem of modem files.
I think what you have flashed is not a correct ROM. Otherwise that should have worked.
Please check your IMEI and then tell me is that IMEI SV slots are showing some value or showing null? Not only Main IMEI solt. There is another IMEI slot called SV slot check that also in about phone-status-imei information

No network connection for Leeco Le2 X526, seems to be an antenna problem

I tried many times flashing Lineage or MIUI, but also with stock ROM the signal is still dead. The phone continues displaying "Cannot connect now, try again later" when I try connecting on a chosen operator or choosing the "automatic connection". What can it be? The SIM works perfectly on other phones, so the problem seems to be of this Leeco.

i have this same problem. new phone....
Have you checked if the baseband is okay? Go to about phone and check baseband version. If it displays the version then you might have a hardware issue. If it's not okay, try flashing a modem from another x52x model (as long as it supports same bands as your phone.)

I had a similar problem with my phone when it was new. I found out that it was a problem with the SIM card. The pins were not well aligned with the SIM card port of my new le 2. I went and got a replacement SIM from the operator and it worked immediately. Thankfully I hadn't flashed anything yet. Try putting a SIM with different pin design (preferably box-ish)and see if it works.

Check if it works with a different SIM card. Maybe the pins of your SIM don't align with the phone's contacts.

G977U, how can I lock to a LTE band and set PS only?

Bought this phone from VZW. After network is unlocked, changed CSC from VZW to GCF, with *#272*IMEI-NUMBER#. I like to lock it to a certain LTE band and do PS only. But found I can't access the service mode to make the change. It only takes *#0011# to display the information. I was told it's because the engineering mode is not enabled on the phone. Is that true? How to enable the engineering mode?

I changed CSC to get 5G in other network. But haven't tried OTA yet.

Bought this phone from VZW. After network is unlocked, changed CSC from VZW to GCF, with *#272*IMEI-NUMBER#. I like to lock it to a certain LTE band and do PS only. But found I can't access the service mode to make the change. It only takes *#0011# to display the information. I was told it's because the engineering mode is not enabled on the phone. Is that true? How to enable the engineering mode?

This app lets you lock 5G/LTE/4G/3G/2G bands on most Samsung phones running the latest One UI software (no root required!):
