No Service on AT&T - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

I fixed this by going into the service menu and hitting "NV rebuild"
---------------------------------------------------------------------------------------------------------------------------
I'm not talking about no LTE like some have reported, I have absolutely not service. No data, no voice, no 2G, no 3G, no edge, nothing. My unlock code came in tonight, I punched it in, it said successfully unlocked, and I'm stuck.
1. Device is not blacklisted. IMEI is clean. Phone status still has IMEI and baseband info.
2. I've tried multiple APNs and restarted after selected each.
3. I have bars, but no service is reported. If trying to make a call, it says "not registered on network."
4. I called AT&T to do anything on their end. Whatever they did didn't change anything.
5. I've tried searching for networks under "mobile operators."
6. Tried a factory reset.
If anyone can help, please let me know. Thanks.
Edit: My sim came from a nexus 6. Everything still works fine after putting the sim back in there.

Can u give more detail on how u fixed this? Thanks!

With help from your thread about the secret menu
I had initially gone in there about a week ago to see if there was any option to unlock like in previous models. I was trying to be careful not to change anything, but I guess I must have messed something up. Somewhere in there there is an option of "NV Rebuild." I don't remember exactly where it is at and I don't want to ever go back in that menu again :laugh:

Captivate not registering on network/holding signal

Yes, I have read every other thread I could find.
Anyways, I bought a Samsung Captivate on Kijijii. I did test it before I bought it, and it picked up 5 bars, and more importantly, held the 5 bars.
Took it home, and ordered the unlock code, which took a few days to get through. In the meantime I upgraded the phone from 2.2 to 2.3.3. Everything seemed to be fine. Got the unlock code, put in my SIM card, put in the unlock code....everything worked perfectly. It didn't pick up a signal though at first, which is a problem with my carrier(I think). They make you go in and manually search and then register. Which I did. Well, for the longest time it wouldn't find the carrier. I have pretty crappy service, so I went outside, still nothing.....went to work and stood under a cell repeater which gives 5 strong bars to any other phone, and my Captivate would show my carrier, I would register, and it would get 1 bar, and then within 10 seconds, it would lose signal again. All while I was standing right beside the cell repeater.
Not only that, but for some reason it would turn on flight mode, and then when I would try to disable it, it would sit there for about 20 min doing nothing.
I went back to 2.2.....still did the same thing. Went to 2.3.3 again, still the same problem. Tried 3 different modems for my specific model phone, 1 of them would find the network instantly, register within 10 seconds, and then drop signal again and go into enabling flight mode, and being a general pain in the ass to turn off. I would actually have to reboot the phone to be able to search for networks again.
The phone came from Rogers, so I put in my brothers Rogers SIM card, and it instantly found the network, registered and gave me 2 bars without me having to do anything. Except then it began dropping signal, getting signal back...dropping it, getting it back. It is winter here right now, and we do have spotty service, but I have Samsung Fascinate that holds at least 1 bar consistently. Not sure if the antenna strength is better. From what I understand they are more or less the same.
I swapped out my SIM card into a different unlocked phone and got service instantly, and then put another different SIM card into the Captivate, and it had the same problem.
I'm pretty much out of options. I'll try tomorrow to see if I can hold a Rogers signal better, which it hopefully can because I'm thinking of selling it.
But I'm inclined to believe that it might be a software problem. Problem is I have no idea what to do in order to fix it.
Any help would be greatly appreciated. Thanks!
Played around with it a bit more. On 2.3.3 with the KH3 modem installed, it will find the network, then try to connect for 10 min, where it will then say 'unable to connect, please try later.'
Then after clicking again, it will say 'unable to connect, select automatic registration' and then sit there for another 5 min. When it finally comes back, I will click on 'select automatically' and it will say after a couple min, 'registered on network', but won't get signal.
All of this I do with 5 bars service. Or in an area with 5 bars service.
Also, the flight mode constantly comes on, and disables 'mobile networks'....so I can't access it. And its a bit weird that it would do that, since any other android phone that I've had, when I lost service, it would constantly try to connect, not go into flight mode and refuse to come out.
Would it help to install a custom ROM on it? I'm going to try going back to 2.2 and test some more stuff. Problem is the small amount of time I spent with 2.2 last night, the phone would crash everytime I tried searching for networks.
After playing around with it even more, I'm convinced that it says 'error while searching for networks' because the phone constantly jumps back into flight mode.
Even when it does get a signal and registers, the phone jumps back into flight mode within a couple seconds, and bang the signal is gone.
Are you flashing with the sim card in the phone? Or if you are flashing through cwm are you leaving the usb cable plugged in?

I flashed with Odin, WITH the SIM card in the phone. I never bothered to take it out. Would it make a difference?
I actually just flashed back to 2.2 with the SIM card in the phone. It found the network, registered on the network, but then dropped signal and activated flight mode again.
Odin flash goes like this. Put phone into download mode, plug phone into USB, open Odin, put 2.2 file into 'phone' section, make sure re-partition isn't checked, click start, and it does everything it should do. Phone restarts running 2.2.
No open ODIN FIRST!!! And then plug in phone... know your stuff before you give false info.

After flashing back to 2.3.3 without the SIM card in the phone, I still get the same problem. But the phone doesn't seem to constantly be going back into flight mode.
Does the modem file change if you go back to 2.2 and back up to 2.3.3? I might have flashed the wrong modem or something.

I'm not quite sure what you mean. I've done it both ways, and each time the flash has been successful.
I should mention that baseband version on my status menu says 'I896UXKH2.'
And I'm running 2.3.3.
So I'm not sure if the modem changes when you go back to 2.2. I forgot to check that.
I thought you were suppose to put it in the pda slot not the phone??

I did actually put it into the PDA slot. Sorry.
Anyways, rooted and installed CM7, installed the KC1 radio, which SHOULD work in Canada on the 850mhz band, and when I search for networks, the only network it finds is Can Rogers Wireless Inc. Up till now it found MTS as well, which is the network I want to use.
I have an MTS(working SIM card) inside the phone. Just bizarre. Could the unlock code not have worked correctly?
Just completely bizarre. I couldn't get any modem to even recognize and find my network of choice, MTS.
So I went back to exactly how the found was when I bought it. Stock 2.2. Going to find out if even a Rogers SIM card will work in it.
There could be two possible things:
1. Unlock code would had messed up.
2. Corrupt IMEI number! Check IMEI number on the box of your phone or below battery and compare with that of the phone (*#06# or settings)...

The IMEI number on the status menu on the phone is identical to the phone under the battery.
So that leaves the unlock code. The guy who gave it to me, cellunlocker.net gave me instructions for locking it to a specific carrier. I tried that with MTS, and it doesn't work. Basically you punch in a code in the dialer, put in the MCC/MNC code, put in the network lock code, and lock it for that carrier. It said it worked successfully, so I have no idea what else went wrong.
The instructions I mentioned above he gave me after I told him the original method didn't work. That method being putting in non-accepted SIM card, and the box pops up asking for network unlock code. I punched the code in he gave me, and it said unlock successful.
Anything else I should do?
I have the similar problem on any 2.1~2.3 stock firmware which I have tried.
I'm using Tmobile now, and the IMEI is correct.
But I only receive 1 bar or no bar signals.

So you unlocked your phone as well? Perhaps the bands are wrong? I know T-mobile uses a different band than other US providers.
In my case, the Captivate uses the 850/1900 bands, which is what Rogers and MTS use.
MTS being the carrier I want to use it on.

I ordered my unlock code from cellunlock.net and it didn't take. I used the Galaxy S Unlock app and it worked fine. When you enter *#7465625# it does show the network lock as off right?

Didn't take as in it said it cannot unlock? Because when I put in the code from cellunlock it said unlock successful.
But I didn't know you could check with that code. I'll do that later. Thanks.
So apparently I had locked the phone to MTS. Put in a Fido SIM card to try something different, and it said enter network unlock code. Entered the unlock code I got, and it said unlock successful.
Now when I type in *#7465625# it says 'off' under all the headings, just like my Fascinate says.
It still holds signal, loses signal though with Fido. I have no idea if that is a problem or what is going on. It'll get 2 bars, or about -99dbm, 5asu, and then suddenly drop it. Get it back again....drop it after 10 seconds.
Apparently flight mode is going on, going off, going on, going off....which is apparently why it loses signal, and gets it back again.

Dangers Of Messing With Your Phone

Hello, everyone, I'd like to share my experience, get any help if someone can, and warn some future people.
So a few months ago i rooted and ROM swapped my HTC one. It was great, I loved it, it was fast and simple.
I tried to change the ROM on it the other day and everything went down hill form there. Basically I ended up having no service and everything else seeming to work fine. So after spending an entire day trying to fix it with BD619, i had to call my carrier today. Now i have the sprint phones, and the sprint service, but i have Credo as a carrier. God knows why. They essentially gave me nothing saying my phone must be bricked and they can't help me.
One thing they did try however was to have me put in a ##xxxxx# number, and there i saw and could edit my MDN and MSID, instead of showing my my phone number and the MSID number they both had "No" written. So he had me edit it and put it in, but when i click "commit changes" it said "commit failed" so if anyone knows anything about that or could help me there, it'd greatly appreciated.
Lesson is, even if you think you know what you are doing, and are careful, weird stuff can happen, and if you have an Odd carrier version of an already less support model of phone (the sprint version), then be EXTRA careful.

Yes, twice
This is not an uncommon problem but it happens with certain HTC ones and not others. I have helped a few other people with this issue. Most likely, your current ROM is set to RUIN/SIM in Settings-> More-> Mobile Network -> Subscription settings. It needs to be set to NV. If you can't get to this setting, you need to flash a ROM that has the setting available. CM 10 based ROMs all seem to have it. If your phone does not automatically reactivate, you can flash to a stock ROM and use the handsfree activation function and that should get you back up.

Okay so i just flashed a CM 11 build. and Holy S*** I have ******* service! I cant make calls, it says it's not authorized. And i don't see the option you were talking about, in mobile network, i see , Data Enables, Data Roaming, Preferred Network type, System select, (then grayed out) Access Point Names and Network operators, (then not grayed out) carrier settings. When i click carrier settings it says "Unfortunately, the process com.android.phone has stopped. and it takes me back a screen.

Try flashing a CM10 ROM. I've always seen the option there. The kitkat ROMs I have used do not have the option except for the Nocs GE.

The only way something like this happens is one of two things.....
1. Ur a noob
2. Your a dev and your testing ril on your rom
The only way to fix this which is a cleared meid of some sort......flashing cm10.1 is the only way and aquiring service by switching to nv....once there everything is fixed just flash/restore back to your rom.

i'd kinda like to argue a point here as this just happened to me. i am certainly not new to flashing, starting back with the mogul and having almost every sprint smart phone since then unlocked (windows) or rooted (webos and android).
Using TWRP and previously running ecliptic 4.3 i wiped caches, system and data then installed the 4.4.2 from team d3rp and voila... no service no meid no nothing.... yes i have the latest radio on my phone.
i guess my point in this is that there's a number 3 that you didn't mention.
3. sh!t happens and it's not n00b related.
for anyone else that has this issue... flashing CM 10.1 worked for me. i didn't even have to set up anything, it just picked up signal. so i rebooted, wiped and nandroided back to 4.3 and all is well.
Did you flash a rom that was meant for another carrier?

I didn't... it was SuperOneK. i'm certainly not blaming the rom though. especially not when others are flashing it fine. the ONLY thing i can think of possibly happening is a bad download. I was in a rush and didn't check the md5.
I had a similar problem when flashing miui. Nothing worked. Even went back to a sense backup and nothing worked.
Commit failed as well.
Here's what I did to make it work again.
Flashed cm10. Change the network settings for CDMA. (Boom it SAID I had service..but didn't).
Rebooted a few times (probably not necessary).
Flashed a sense 4.3 ROM that was close to stock.
Update msl and all that. Commit.
For me..changed LTE/CDMA to just CDMA (no 4g in wv).
Boom it worked again. Hope this helps!

No Mobile Data after Lollipop Update

Hi there, I've got an european HTC ONE with Vodafone Brand. Yesterday I got the message to update to Lollipop. After this fails, because of ElementalX I used my old Recovery Image and restored it. After that the Update went well. Now I was outside the first time, without Wifi and mobile Data won't turn on. The Telephone and sms works great. Now I don't know what to do. Any Ideas?
Is there The right apn in the settings picture below.

Go-to settings - mobile data - access point names - 3 dot menu in top right and select reset to defaults, the screen will change and you'll just have to select your mobile operator from the list again, give it 2 mins and it should work.
When congstar is not in The list you have to add a apn manualy with The right settings ( Google helps )

Last thing I can suggest is get the apn settings off your operator and manually enter them, sometimes they can send you a data packet in a text message which will automatically update the apn for you.
You usually get these same type of texts when you put a new SIM card into your phone, just got to ring them and get them to send it manually this time.
Hey tried that too. Set everything up, restartet, but no mobile data. Any idea?

contact your carrier, or even better, bring them your phone so they can confirm the APN is set correctly and that there is no problem on their side. Then you might want to try a factory reset before trying anything else.
Hi, I just had it short times working. Sometimes it is very short times there but most of the time it is not connected. Is it a Must to add an APN manually? I have never done this before.

No, it's easy, again goto settings, mobile data, 3 dot menu in the top right and select new apn, you will be presented with a load of things to fill out, you can usually get the details from the help section on your mobile operators website, or by calling them and have them talk you through each setting, not all sections need to be filled out, then save it and set it as the one to use rather than the other one you have now which doesn't work.

I had a similar problem when setting up an APN on Virgin mobile,sometimes,some of the settings can be different with the same provider.
I would google the APN settings issue you have specifically with your carrier and see if there are any forum posts which suggest slightly different settings.
In my case the carrier settings for APN type were this APN type — internet + mmsand didnt work...I was told to try this APN type default,supl,mms
And it sprung into life.
It could something that simple
Hi, I just get it to work!

n900a note3 running on tmobile.

So, first off let me say this,
ive never posted in xda before and im not sure if i should be here, or posting in the tmobile section.
but, what i am having a problem with is intermittent signal/data loss.
once i boot the phone up i get a circle with a line through it for about 5 minutes then it reads my sim,
heres the weird part. i put in my apn setting for tmobile. i can call out and recieve calls, texts and pictures (when it finally starts to work), but when i try to load up my web browser its like i have no mobile data (i have mobile data enabled). on wifi it works fine.
after a while it just drops all signal for what seems forever and it will eventually come back.
my question is, why does it do this and what can i do to fix this.
running 4.4.2(or 3 idr) stock everything (minus the apn settings and ****). lol.

These is for a Note 4, but I can't see why it wouldn't work on Note 3. APN & data settings https://support.t-mobile.com/docs/DOC-14688#apn_settings and make sure your data is turned on.
I have the apn settings set to those exact specs.
I knew the bootloader was locked so I just went ahead and paid to have it unlocked so I can use my son in the phone.
I'd attach a screen shot bit I have no idea how to.
It literally took it 30 minutes to get signal.

No Service even with full strong 5 bars signal

Hi,
I used my Note 4 for 10 months and today it said "No Service".
I backup and reset the phone, still issue.
I went thru Settings and manually select network, still issue.
I take the SIM out and put in another phone, it worked fine.
I put a working SIM from the other phone, still "No Service" issue.
I never flash firmware on this Note 4.
I don't think the cell radio is dead because the phone has full 5-6 bars strong signal.
Could it be blacklist for some reason? (I bought it from ebay and the seller unlocked it before).
Any help appreciated, thanks.

Dial *#06# and see if it shows your imei.
If it shows lots of zeros or ( NULL ) then it might be corrupted or black listed.
Try this app and run it this will refresh your modem and radios

Thanks for quick reply. *#06# returns same IMEI and SN as in the battery back. I installed and ran the tool as well. Still no service.

Try this steps 1 by 1
1,Go to settings/mobile networks/network mode and change to 2g/gsm and reboot see if it works.
If 1st method dosent work then try 2nd or 3rd
2,Backup everything and factory reset
3,try flash fresh stock firmware via odin tool and do factory reset after flashing firmware.
If all of this doesn't work for you then might be hardware issue in sim slot ic or radio antenna not sure.
Try different sim cards.

Check your APN in Setting/Network. Should either be AT&T Nxtgenphone, AT&T PTA, AT&T Phone.
Thanks everyone for helping out. I ended up calling tmobile after checking the IMEI and they unlock it for me because it was reported as lost/stolen.
