Phone shows network but no data connection or calls possible - Galaxy Note 4 Q&A, Help & Troubleshooting

I have purchased a used Note 4. It was already rooted so i went ahead and installed Nameless ROM and the appropriate bootloader_modem.
Now, i have no data connection and can't make any calls. Even if the bars show that there is coverage. WiFi works fine.
My first idea was to revert it to stock so i downloaded the N910GDTU1COJ3_N910GXSA1COJ3_XSA stock rom and flashed it in Odin. Full wipe and cahce clean after the flash.
I am still facing the same problem that the phone doesn't have data or voice service. Any ideas what else to try or what could be the problem?
TIA

Anyone?

for me...i always lost signal... i dont know why...910f

Same issue
Went back to stock ROM a few months ago, but this has just started with me. 4 days and not able to connect to any data service.
Tried new Sim and manual network selection, just refuses.

Hi @dosada, i guess I.have the same problem as you, I can't connect to any 3G or 4G anymore. Now, I only can use 2G and Wi-Fi. so try to put network mode to 2G only, because if you put network mode in 4g or 3g or 4g/3g/2g automatic or 3g/2g automatic you will always end with Emergency calls only or no service. I already asked help for that but no one can solve it. I already tried everything I know but no way, no one can solve it. So just courage and let us know if you get solution somewhere.
I think that it is the last time that I use or buy a Samsung phone, they really suck recently. it's better to spend our money to buy other phone than Samsung, they lost the trust of their customers. They were number one but now...puffff...

serious 3G/EDGE issues with my G1

I have a rooted G1, iam running JF 1.42 RC33, i also have RC33 Radio.
i live in Chicago in a place where the 3G coverage is pretty good. in fact a month ago i was having perfect reception on my G1.
recently; i am having many issues with the data link (3G, EDGE)
simply, the phone does not pick the data link properly, and even if connected, it might drop the connection.
sometimes i have to go to settings, wireless, mobile networks, and click on "use 2G only" a couple of times to trigger the phone to connect... it will drop the connection when it goes to sleep !!!!
i have noticed that many times when the phone sleeps, it does not switch properly between the wifi and 3G [or EDGE], so i dont get my emails.
sometimes a reboot solves the problem, and some times it does not
i tried to flash the radio image again,,,, it didnt solve the problem.
any help will be highly appreciated.
If you've tried to reflash you radio and the results are the same it may not be your phone. It may be the network itself. You should call TMo to see if they have any issues in your area. About a month ago half the country went out for also half a day. It's rare but it happens. If no one else is having issues then it's possible the problem would be with the phone. You could try a wipe and/or reflash but it probably won't make any difference since it sounds like the radio (which you already tried flashing). Maybe also try checking to see if turning off data roaming will make any difference.
thank you for your response:
iam having this issue since a couple of weeks,, and i dont think it is a network issue.
i have tried to disable/enable data roaming,,,, it didnt help.
am i left to a "wipe" only.. ????
well you can give that a try and if that doesnt solve your problems then it may actually be a defect with your phone. also... ive had issues that my phone would lose data and voice even while i was on the phone. it would just disconnect then say no service. the problem wasnt my phone though... it was my sim card. if that sounds more like your problem you can get a new one for about $20 through a tmobile store.
i didnt encounter any voice call drop issues.
when i wipe, i will need to reflash everything, right?
I live in the chicago area as well and my edge/3g has been off and on like crazy over the past 4 or 5 days. I will look at my phone and it won't have an E or 3G. I'm running jv1.42rc33 with apps and caches to sd card. I'm not sure if its a network problem or my phone itself.
So you both live in the Chicago and are having issues with 3G/Edge and you doubt that it's a network problem??? I hope you didn't do your wipe yet.
I'd call T-Mobile and ask to speak with their data support (Tier 3) group and verify that it's a problem with your handsets before you do anything (like reflash, wipe, etc).
i live in chicago as well.
T-Mobile was/is having 3g network issues. T-Mobile where not aware of the issues. They say they are on the issue to solving it. :

I didn't explain myself well there. I'm under the impression it is a network problem. I learned my lesson last time there was an outage. I did like three wipes in four days thinking it was my phone.
It isn't you - my 3G (also Chicagoland) has been up and down since Wednesday. It is completely down again this morning. All day yesterday it was probably up for no more than an hour.
F'ing T-Mobile made me wipe my phone, then drive to the local store to get a new SIM, and they refused to acknowledge that it was a network issue. The sales rep at the T-Mobile store was having the same issue.

DOH! That sucks! LOL. If you're referring to the outage that we had about a month ago I took the liberty of posting a thread on here warning people not to wipe because they might not be able to sign in because of the network issues. There were so many that did and I was almost one of them myself until I wised up and decided to call first.
hello guys,,, thanks for everybody who in contributing in this thread.
i can see iam not the only one having issues in Chicago, t-mobile said they had no problems,,,,
what makes me tend to believe them is sometimes if i play with the phone the 3G shows up,
this is an experiment for you to try (it worked for me):
enable tethering using the open source gui, then disable it again.... 3G shows up !!!! even if you enable wifi... the phone will switch properly between wifi and 3G (when sleeping).
it worked for me last night and is still working now.
if you guys try it and it works,, this means t-mo has no problem,,, and we need to figure out what is wrong with the combination/configuration we have...

Nexus One network issue

Hi, i was using CM7 for a week, then suddenly, the mobile network begin to be freaky, cant stay on a network, cant make call and anything, I already cheked the apn settings and everything..
also switched to wcdma prefferred, to gsm only, or to wcdma sometime got signal, but after 1 or 2 minutes, cant connect to a network...
anyone can help please..
I'm having this as well ever since the update.
Gingerbread is half-baked if you ask me.
it seems to make and receive calls only in EDGE (in GSM ONLY mode), but when i change it to preferred wcdma or to wcdma only to get 3G, sometime get full signal but cant make any calls and also cant use data and sometimes got no service.. only in EDGE mode..
all this happen after using CM7 for a week... anyone please help..
baseband and radio are 32.50.0032U_5.12.00.08...
I also restore it to stock to FROYO FRF33 and the same issue, dont know what cause it..
I'm not sure it is fully related to gingerbread. I'm still using CM6 and had this issue on and off for about 3 days. It seems to have cleared up for me (knock on wood)
Sent from my Nexus One using XDA App
yess im having the same problem, i also noticed it after flashing to either honeycomb alpha or the new gingerbread update [i did both within an hour] but i cant fix this problem...:/
still cant connect to 3G, only in EDGE mode...
cant connect to a 3G network, already changed the radio to 5.08, 5.12 and downgrade it to 4.06 and nothing...
anyone know this issue??
if I cant solve it, I might gonna sell my Nexus One..,
Network issues have nothing to do with the phone, if they're constant with different ROMs. Check with your service provider.

is not the service provider, I change the sim card to another phone, and the 3G works flawless.
Also, put another sim of other carries with the same band, changed the APN settings, and it's the same problem with 3G, only work on 2G...
In that case, 2 options:
1) Wipe and check again.
If still doesn't work -
2) Hardware failure. Use the warranty.
I've been recently (1-2 months) battling with Data problems also and I don't know what the issue is. I know it isn't my Carrier because I just spent the whole month on the phone with them and they actually sent a Guy TO MY HOUSE to test the connection. I've never had problems before until around CM7 and me switching plans (which is what I thought it was).
My problem is that it works, but data just stops and doesn't want to reconnect. I have to toggle Airplane mode or reset to jump start it. I think changing towers while driving might do this too.
I've done the same tests. Changed Sim, Swapped Sims, etc. EDGE seems to be stable for me but 3G is wonky. I've flashed a PASSIMG and started from scratch that way back to root and CM7. I've downgraded my HBoot and reupgraded it. I've wiped and changed radio versions.
Right now I plan to swap to a few other Gingerbread roms and see if that fixes it. My N1 being my only internet connection it is hard to download other custom roms but I grabbed a few from work and put on my SD card.
I'm not blaming CM7 but at this point I'm really thinking about changing phones.
Ive read that there are issues with the Nexus One gps. Is this true and if so, what issues have you experienced?
PS. GPS doesnt have anything to do with the carrier does it?
well... my nexus already have 1 year, I'll sell it in a very cheap price, and buy the INSPIRE 4G and root it...
thx for your help guys..

Bell Galaxy S2 On Telus Network - Network Drops Every 10 Min

Hey everyone,
Had the Galaxy S2 since Saturday, unlocked the device, everything was working great. Out of no where, yesterday the phone still shows the H+ logo and full signal, yet i cannot send, receive text messages, initiate a data connection or make/receive phone calls.
In order to get all that ability back, you either have to 1) reboot the device, or 2) turn airplane mode on then off.
This only works for roughly 10 minutes before it all happens all over again.
I tried swithing to WCDMA only, but issue still persists, even tried some menu codes I found on another thread to disable H+ but the same thing happens.
This is currently happening on the bell shipped rom with no root or anything of the sort.
Has anyone experienced this?
I've searched for hours but can only really find complaints of data connection loss only. In my case it's everything. Data / SMS / Cell
Any help would be greatly appreciated.
I feel your pain, even though I have an XEU unlocked GS2, I've updated it with every update from kies hoping the issue would resolve.
Even with the latest KF3 update the issue persisted, however the phone could be used on Rogers with no issues, on Telus data drops constantly.
Disabling fast dormancy didn't do much to help.
However since updating the phone to KG3 2.3.4 yesterday I have not had the issue happen again. For the first time since I got the phone it no longer drops the data connection on Telus.

Thanks for the quick response. Was it only your data that disconnected, or everything else?
Also, may you please link me to the update? I suppose I could use that as a last ditch effort before exchanging the device before its too late.
My issue has changed over the past couple months, originally the phone would report that it dropped the network and when it came back data wouldn't work until airplane off then on or a reboot.
Lately things seemed fine with occasional data drops until yesterday, when it had full signal but I couldn't use data, sms or make a call. It was basically a paper weight until I updated it. The link to the file which has everything you need to update from samfirmware.com is below.

*edit - I'd make sure you have a back-up of your current firmware in case you need to flash back and return the phone.
I have the exact same problem. Bought a bell gs2 unlocked it and now with telus. My data dropped constantly and now I'm using the newest litening rom and now it only drops maybe once or twice a day so a huge improvement

If it's any consolation, I ran my Virgin SIM over the weekend (just to burn up the data I had to buy for a 1 month) and the same thing happened on stock firmware.
In my case, it would put me in "emergency calls only" mode, saying I wasn't authorized for the network (i.e. it wasn't recognizing my SIM). Tried the usual stuff (re-seating SIM, using the Telus SIM, reboots, cache wipes, network WCDMA/GSM selection etc), and nothing fixed it, it just seemed to come back on its own when it was good and damned ready no matter which SIM I used.
Flashed to "Frankenstein" KG3 on Sunday, and neither the Virgin or Telus SIM has lost network since then, in the same areas. WiFi seems to be working better too.

No 3G signal at all, but not quite the same

Hello, first to say, im not a newb, noob, newly registered, or a guy who dont understand anything from android.
Im not posting stupid topics, or topics which answers can be found easily on internet/google/xda/forums and such.
I am running stock rom, only rooted (i used to root it only to apply some xposed settings and clear some unnessesary apps, nothing more, nothing less).
Here is the description:
My phone has no warranty, i bought it online, brand new from UK, simfree. At that point, i had no problems with the connection. i received OTA Update - about 50-60 mb, but the phone remain 4.2.2 as it was. I still had no problems with the connection. After some time, the phone was left alone inhome for a few days, may be a week, it was turned off and it was not used at all. When i got back, i inserted my sim card, and i saw it is showing only G icon, and no 3g/h/h+, nor even 2g. I live in big city with very good network coverage, so its not network problem. I dialed up the customer service (Globul Telenor Bulgaria) , explained them my problem and asked them to check if its operator's problem or sim card problem, but it is not. The sim is fine, so is the network coverage. I dont have other operator's sim card to check the phone. I tryed several possible solutions found in google/xda - turned off the phone, removed sim and battery and left that way for few hours, still have the problem, tryed to switch operators manually and register sim card to other operator then back to mine, not working. Several times reseting/ deleting APNs, switching airplane mode, data off/on, adding apns/searching for networks and all available combos, not working asked Globul Customer support to send me new settings- not working. The only obvious thing i havent tryed is the factory reset (I still need to do a backup first and dont have time to do it right now.)
In Settings- More networks - Mobile networks- Network mode i have 2 options - 2g/3g auto connect and 3g Only. When I choose only 3g - i lose any signal, like there is no sim card. Reverting back to auto 2g/3g is registering my sim back to Globul network.
Then i decided to root my phone if i can find a fix for the connection. Rooted with CF-Auto-Root thru Odin. (The 30sec Root)
Looked for some tweaks in xposed modules and settings, i couldnt find anything related to 3g. Still looking for a solution...
I repeat - my phone was completely stock and non-rooted when the problem occurs! Now is rooted with stock rom. (this is the diffirent from every topic i searched.)
Im attaching some screenshots, if someone can help me. 2g is really annoying and slow as hell.
Well the first thing I would do is update your phone. You are running 4.2.2 which is old. Update to the latest version, that could either be a stock rom or a custom rom.
After that do a factory reset. Make sure you backup your internal storage etc, because it will wipe it clean.
Factory reset, updated to 4,3, after that 4.4.2 problem still persists.
No 3g at all. Its not the sim. Any way to fix it ?
Soo no way to fix it? Should i give it for repair?

[Q] network problem (very strange)

Hi guys, first of all i made searches and etc. and found nothing, this is very strange issue,
i have an s4 (I9500) and cell network is not working well. in E mode (i mean 2G) all internet voice and texts are working as should be.
in combined mode, if internet open then no network, or sometimes E with data but no 3G anyway. when internet disabled all is good.
in WCDMA mode, if internet is open, then nothing no internet, no voice no text. when internet disabled all is good again.
strange thing is i can use 3G very different way.
check 3G or combined mode first
make a call
after connected call open network data ( internet)
in a few seconds i have 3G internet. but if call ends no data again and after while no network either.
for troubleshooting in 3G mode before signal lost i see H or H+ sign on my phone but only up arrow shows no down arrow i think that mean 2 thing
1- i send a request to carrier but no returning
2- i cant send a request but phone try to send.
it was the same in 4.4.2 firmware, now i have 5.0.1
i try to patch modem with other firmwares modem files but i could find only 4.4.2 modem files. and tried all of them but no luck
so i want to use 3G mode, my phone has warranty but glass broken and in my country it is avoid warranty.
i have no box jtag or z3x box only have cwm mode and odin with usb. so is there any solution to my problem.
my phone info :
Android version: 5.0.1
Baseband version: I9500XXUHOD4
KERNEL VERSION: 3.4.5-4727708
Build number: LRX22C.I9500XXUHOD4
stock firmware with no patches just root.
my origin country where i bought phone is Turkey.
i will be greatfull if you guys could help me..

Looks like to me software problem too but i cant fix it.. Thats why i choose title as strange i dunno what to do now..
I think im having the exact same problem, it has been like this for the past 3 months. Unable to find any solution. Tried pretty much everything. The problem started 3 weeks after I installed cyanogenmod. Flashed back to stock rom but it didnt fix it.
Let me try to explain it:
I ONLY got internet + a normal cell signal when im on GSM mode.
As soon as I switch to WCDMA - WCDMA/GSM or LTE/WCDMA/GSM I dont have any internet or a cell signal, leaving me with the only option which is GSM, but that gives me Edge internet which is really slow.
The things I tried so far:
- Different ROMS
- Stock ROM
- Updated my APNs manually and automaticly
- New sim card
- Opened my S4 to check for any damage or water damage, everything looks fine!
I tried my SIM card in my friends phone, I got perfect 4g then.
Im starting to believe its a hardware problem
