rooting will not kill your network connection. that's something that you did. you need to provide a LOT more information in order to have people help you out,
what ROM are you on, what settings did you change, what mobile carrier are you on, etc. etc. this is a simple fix, but we need to know what caused it first. :good:

The SIM card can not register to my network has it something to do with the imei??

IMEISV: 01

Never give out your imei number

Well the person above me said it. You just made a mountain out of a mole hill by giving out your imei to everyone on xda. Anyway, have you tried a factory reset? If that doesn't work take it to Best Buy and tell them Kies wrecked havoc on your device and they can re-flash your phone for free. Don't tell them it was your fault.

I don't know what the problem is but you should be able to flash the stock firmware in Odin and get your phone working again. Double check this in the i9500, i9505, i9505G S4 forum. You can get the stock firmware from sammobile.com

He should be able to flash it himself. The i9505 is not locked down like the i337. It's an international version so he probably can't take it to best buy, which is what I was responding to.

Data enabled, but no internet connection
Hello,
I have the stock rooted i337 (AT&T), running on another provider network. I am aware that i337 is very difficult to do modifications due to the built-in by AT&T vicious locks to prevent using it with other network providers. This is the reason I did not flash ROM, because I am afraid to get my phone bricked and lose it entirely. Recently I subscribed to a data plan from a third party provider and I have 4G in the status line and HSPA in the data type, but I still did not have internet connection when WiFi was disabled, except that my Hotmail somehow worked. No other apps requiring internet worked. I spent a week researching the issue myself as well as working with the provider's tech support, but nothing worked. Two days ago, almost out of despair, I installed a new app called Opera Max, which is developed to route the unencrypted data to their Virtual Private Network in order to compress it and save the data use. As soon as I connected to VPN, all applications started working. I still have to turn Opera Max off when I use WiFi, because it disconnects my WiFi every few minutes, claiming that WiFi signal is too low. (My signal is very strong and no other devices have any issues with WiFi). However, this is a minor problem, considering that Opera Max saved my data plan.
It is still a mystery to me why Hotmail worked, but no other apps and why using Opera Max VPN solved the problem. If anybody has ideas, I will be happy to hear.
I must say that all data settings, including APN are checked, rechecked and correct, so this was not the issue.
Thanks,
Dan

I am also having connection issues after rooting my S4 i9505:
I am on a Telcel (Mexico) which is supposed to support 4G connections... However, ever since I rooted I can only access 2G/GSM networks. I have the official APN network configuration and I have tried two roms but still no luck...
Any advice would be most welcome.

Check your APN settings. Also, try a SIMswap. Old sims do not like new phones, and mobile data is the first to go.

APN is done by Vodafone automatically, checked it manually too. It's proper. Of course I cut my SIM. Big sized SIM can't even fit this device.

Ahhh, there we go. Try a different SIM. Either it's too old (anything before January 2013 is too old), or you're one of the 50% where cutting the SIM causes problems.
(Yes, I know it doesn't fit. 30% of my day revolves around people with faulty sim cards.)

tried update modem?
basic problem lies on the APN setting. but if you said you have checked it and all ok, try to update your modem into your device latest modem.
I use a big simcard cut into smaller one, and no problem. I have old simcard since 2011 as well.

Like I said in the OP. I already upgrade my whole firmware. Modem is updated too but problem is still same.

Put your SIM card into another phone and test.
You may have to check with your mobile operator for data-service registration.

u can try what vndnguyen said.
But, just to comment... actually, when you upgrade firmware, normally it won't flash any modem/csc. You will need to do it manually.
This is what I know when I experienced on any official firmware upgrade on my device.

yep. that's the modem.
pull it out from the zip. and flash it from ODIN under CP.
when you go to download mode, make sure you switch your phone completely OFF first. then go into download mode by 3 combo buttons.
if 1st try fail, no need to worry. repeat the same steps, and you are good to go.
Sometimes I need 3 times to succeed. Don't know why also. Sometimes 2 times, and sometimes 1 time also no problem.

I (as with others) are having the exact same issue and is actually something that has been brought to Google's Attention: https://code.google.com/p/android/issues/detail?id=63524 Note that the Android Issue tracker refers specifically to The Nexus 5 but other users in the page are also having the issue on other devices, like you and I.
I have tried multiple different possibilities to fix it but still no solution.

My bad guys. My internet package was out. (I didn't pay -.-) Paid now it's working.

[Q]

I have a n9005 XEO that i bought on ebay. it was working fine for about 5 months now until a few days ago when it just stopped getting cellular signal altogether. no calls, no data, nothing. it seemed to corespond to me using towlroot, installing supersu, and a couple of xposed add-ons, but everything seemed to work fine for a few days before i had this problem. I tried making sure that airplane mode was off, data was enabled, that i had the apn settings correct for my provider (at&t, USA), I even went so far as to restore to factory settings, and then flash another rom (the stock s5 port i found here in the dev forum). still not getting cell signal at all). I went so far as to go to the local at&t store and ask them to place my sim in a known good phone to make sure it has service (and it does and is provisioned properly and i'm paid up). my note sees the sim (i.e. no "sim not found" messages), just plain no service as if i were in a dead zone. the phone hasn't been mishandled, i've tried pulling the battery and putting it back in... I can't think of anything i'm missing here besides trying to flash the modem (which i can't seem to find the stock modem (n9005xxuenc2) or firmware on a site that doesn't take 7 hours to download it from.
can anybody help? (either with a mirror that doesn't suck for the latest stock firmware or latest stock modem, or offer any other suggestions?)

it's an n9005 xeo from poland, I'm in the USA on AT&T. I downloaded the firmware successfully from sammobile and installed it with odin 3.07 which seemed to go successfully but I still get absolutely no cellular
I've tried using the default apn, tried using at&t's apn settings (which i remember having to do last time before i got data but i'd always been able to make calls and that's not working right now either), no effect...
anybody have any ideas?

So you're saying it worked perfectly for 5 months, and then suddenly it went haywire on you? Did you do any major changes before it happened?

as i noted I rooted it with towlroot, installed supersu, and a coupe of xposed add-ons. but everything was working afterwards for about a week before i had this problem. otherwise, I was using my phone one night, i wake up, and see that i have no service. it was after a big storm so i figured they were doing service on the tower, until my work iphone rings (on the same network) and that feeling of dread set in so i went about trying to diagnose the problem and here i am.

despite having done nothing unusual to the hardware, I've flashed modems (stock and otherwise), i've flashed roms (stock and otherwise) and it doesn't appear to effect my situation, so I can't help but think that this could be hardware related... I'm stuck and sad.

even if it were blacklisted, it should still allow me to place 911 calls and the like. it should work like a deactivated phone. it's not. just in case i was wrong, I also verified the imei on swappa and they confirm that it is indeed NOT blacklisted.
also i'm not sure why it would be blacklisted to begin with. it was working one day then i went to use it the next and bam, not working. i don't get it.

Sounds like your IMEI got tampered or stolen and got blacklisted. Usually this would happen, especially when buying phones online.

But I've used several reputable services to check my IMEI number and they all say that my imei is in good standing... I don't get it. besides, what causes an imei to be blacklisted to begin with? - I wasn't trying to circumvent any security features, had no malware, no reason at all for an accounts admin to want to get me off the network. my account is in good standing, and my sim still works in an old iphone that i've got (i'm using that until i can sort out my regular phone situation).

The fact that someone had the phone with them can easily get it stolen. It's a plain 15 digit number, easily forgeable just by looking at the box, and since it has no authentication, people can just get your phone blacklisted by placing it on a defunct phone that hacks the network (or something).

well tonight i took it apart to see if there was a problem with the antenna cables, connections to the various peripheral devices and such and alas, no effect... still does exactly the same thing after field stripping the unit and resenting everything. if it's hardware, it's nothing i can tell...
I was also able to generate a .pit file, grab the latest build for my csc from sammobile (takes forever) and did a nand erase in odin with the pit and the downloaded stock rom... everything went great, but it got me to exactly the same place i'm at... working phone, no service. I have no money, but i think i'm going to just end up ebaying it and buying an s3 until i can save up enough for a note 4 or nexus 6... for now, i'm on a crappy old iphone 4 with a broken lock button, but that's another thread.

well it's been about a month and a half since i've had a decent phone (my 3 phones ago iphone 4 really doesn't cut it). after giving it some thought, I think i might buy a broken-screen sm-n900t, and swap it's mainboard into my phone. hardware-wise i believe they are exactly the same, it should be easily rooted with unlocked baseband,it would give me LTE on at&t, and it should be easily unlocked so i can use it on at&t... it should also only cost me 1/8 the cost of a good condition used n900t. ($60 or so on ebay i hope?).
still pretty sad that such a nice phone quit on me so quickly

Why don't you swap the N9005's screen onto the N900T and keep it like that? The N900T if I can recall, has the most bands available worldwide and if you're already replacing it, just enjoy the vast amount of customizations and potential the N900T has.

Did you pursue all avenue including Samsung service/repair centre or even Samsung line enquiry to confirm it's not blacklisted?

that's basically the plan, except the motherboard lives on the display side of things, so it would be swapping in a new motherboard (n900t). we both describe the same plan of action.

Mobile data issue

My note4 almost always has a white 3g above the service bars. However, even though I still have 3G and there is no change in service bars, periodically my text messages will not send and internet will not work. Keep in mind that my phone constantly says it is connected to 3G. It also happens that the signal bars disappear. After reboot both are OK. *
I do not have any malicious*apps*and my phone is not rooted. Have messed with network settings and have seen no change.
And YES my mobile data is turned on.
Any help is appreciated!

I have the same problem, right now I am trying to figure out if it's software or hardware related...

I would hazard a guess that it is sim card related.

You got your phone from Orange? It never happened to you that it looks like the phone has signal, but in fact the signal froze and I cannot make a call or to be called. After a restart it's ok for a while. Also if I turn mobile data off is ok.

If have exactly the same issue !!!!
Start with full signal strength and going down to the lowest strength and minutes later no signal !!!
Reboot or Airplane mode can undo this, but the cycle starts allover: Full strength, less strength and no signal.
Tried with 3 different carriers !!
And 2 Note 4's !!
I have the Snapdragon version SM-N910F
What is going on ??

Have this issue with my exynos variant in australia its imported and full 3g signal and slow or no data throughout and sometimes h+ even g or nothing

Next week samsung will come to me and bring my phone to their service and will check whats going on. Anyway I think it's more like hardware issue than software.

I have the same issue with exynos variant I bought the fone from the official dealer in my country,
My data service was not working at all.
I got it working by going to mobile network and choosing WCDMA/GSM option instead of LTE/WCDMA/GSM. although now i cannot get 4g but at least the data is working on H or H+

I think its software as a few people have had this issue both variants also

Same problem here, Exynos factory unlocked SM-N910H. All of a sudden I look at my phone and I discover it's showing "Emergency calls only", sometimes H or H+ but no internet. A reboot OR Airplane mode OFF and then ON will solve both problems. That's ridiculous... I've literally tried everything, factory reset, changed sim, messed with the APN settings. I've had this problem since day 1, even before I rooted it. Darn this, I never had any problems with my HTC One X, and I am using it ATM until Samsung come up wit a fix with an update or something. I hope it's not hardware related as my Knox warranty is void 0x1. :crying:

The same issue happened to me. I have 910c variant from Lithuania. A week ago phone started to lose 4G and after few minutes "no signal". Few reboots and it is working again, but after some minutes there is no signal. What I did notice is that there was no signal problem in my city centre where 4G signal is very strong, but when I did some speed test there, it was only ~2-3mbit (before this problem it was ~50-60)... Unfortunately I did not test this issue by turning off 4G. I did deliver my phone to warranty service 5 days ago and they send phone to Latvia to do 4G tests. I refused to repair my phone and demanded to get new phone. Waiting for the answer

Also rooted my phone so no warranty for me. Changed carriers today and they are doing upgrades so stuck with useless service :/ but i think either it's something to do with root or software i dont think its hardware

Fuxas plz reply to.this thread when you hear back thanks

I dont think it is software, because I tried factory reset and it did not help.. Of course, when I get the results I will share them here.

If anything it's NOT the root because I am having this issue before I ever rooted it. My best guess it's the software and I've researched a lot about this problem, seems it's specifically related to some samsung devices and not only the Note 4.

Yup its a samsung problem and hopefully it gets rectified

[Q] No Service after period of time

I have an Australian Telstra Galaxy Note 4 (SM-N910G). I got it today. I have rooted it and thats all.
Twice now, I have just had it on charge, the screen off. When i've gone to use it after about 30 mins or so, it has no service. Nothing I can do will fix it other than rebooting.
Not sure if its a fault with my phone, something wrong with the root or a software issue.
Does anyone else have a similar issue.
Both times its happened its been on charge. I'll take it out with me now and see if it does it just in my pocket.
Thanks

Maybe you need to change the network mode to WCDMA/GSM (ie turn off LTE if it's not available).

Tried it no good.. disabled xposed completely and seems to be normal for now.. ill report back if i havr this issue again

Nope same problem again.. hmm gonna do a reflash of stock rom when im home. My guess is software issues

It just did it to me after being off charge for half hour. No idea what triggers it.

Nope not sure but frustrating as hell

Same issue. Have sent phone in for repairs. They found nothing wrong with it. Sent another new Note 4 replacement having the same issues: No service after checking the phone after an hour or so

Oh I was looking for a thread about this issue, mine is sliiiightly different though.
I'm on 4G, but I use WiFi whenever available. I then notice my battery draining 1% per 30 minutes even though I'm on WiFi, when normally it would be 1% per 1+hour. When I switch it off WiFi, the 4G signal never recovered but showing 2 bars of signal (which is normal at where I am). Switching to WCDMA didn't bring back 3G, then switching back to LTE also did not bring 4G. When I call to the mobile, it will go straight to Voicemail as if not connected.
And yes, Flight Mode ON then OFF restored connection.
I'm on stock everything, disabled bloatware, no root.

Network not available after root on Note 4
Hi there, My Note 4 was working fine before root. I used a wrong root file so it stuck on Odin and after rooting with correct file it again comes in working condition with no service or emergency calls or network not available. Its IEMI and serial no. is fine. I can see 4g written near network and 4g works. I can use Internet services but not Call services.
I have tried stock firmware wia kies and Odin. Now using Sweet ROM V7 but nothing works. If I use 2 degree 4g Sim then I can use calling services on it and if I disable 4g then again no service nd nothing on it.
This happened after rooting. Tried different modem files given on Sweet ROM page but still same problem.
Please help me.
