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
Kernel version: 3.4.0-1715731

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.

[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?

I also tried flashing the XXUENC2 and ZHUENB5 modems from here with no effect.

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.

anyone have any other great ideas for me or am I buying another one?

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.

[Q] The term (bricked phone) what does it mean?

I noticed a lot of posts warn that you may brick your device.
So what they mean?
Your device will not boot?
Your device will not receive the carrier signal?
I want to know more about this term.
I ask this because i have US Cellular Galaxy S4 and i can boot normally to android but i don't receive the carrier signal even after i flash the stock tar file but no way to make the carrier signal come back.

"Bricked" is kind of a broad term. It usually means your phone won't boot at all. How are you flashing the stock tar? What happened with the phone right before it stopped getting signal?

A*bricked phone means*one thing:*your phone won't turn on in any way, shape or form, and there's nothing you can*do*to fix it. It is, for all intents and purposes, as useful as a*brick. A phone*stuck in a boot loop is not*bricked, nor is a phone*that boots straight into recovery mode.

[Q] SM-G906K audio problems while calling: how solving?

Goodmorning to all,
I am Loris from Italy writing: I am new here and I am not sure I am doing right so, if I am wrong writing something, please tell.
After this I can tell you my problem: I bought a SM-G906K, Samsung Galaxy S6 Prime from Korea as you know, and I soon had problems while calling: if I am calling or receiving a call, sometimes soon, sometimes after some seconds, sometimes after some minutes, or sometimes it does not happen, I can not see anymore person speking on the other phone, but note: they can hear me.
I already try to call even with Skype, and it seams there is no problem: audio is ok even while reproducing video and so on. I tried making calls in emergency mode too, just to understand if some app could be bad, but I have the same problem, always and ony with calls.
What could I do? Please help me, if it is possible.
I am using a 4G Vodafone MICRO SIM card.
Best regards
Loris

Put your sim card into another phone and test to see if the problem persists?
That maybe the problem of the network, not your phone.

Goodmorning and many thanks for your answer: I already did that, I already changed 3 sim card too, but the problem is going on: with my old SIII all the sims are working as well. Maybe could something work wrong between network and the phone connectivity? From Korea they told me there would not be any problems at all ... but I am seeing it is not like that.
Anyway sometimes I can do calls of 5/10 minutes without problems...so it is strange it is a network issue, is not it?

I said that may be a network problem. As you have tested with another phone without problem, I doubt that is the problem with your phone.
Try to factory reset to see if it helps? If not, it maybe a hardware fault.

I already tried to factory reset by Kies many times but it does not help, and I noted that updates remained on firmware, they were not brought at factory state.

I really do not know what to do ...

Could it be it is the mark Olleh giving problems? Maybe using a G906 not K (I think this is properly for Prime Special Edition) but S it could work good: don't you think so? K and S are the same, is not it?

Call your WIFI provider and ask them to change the channel. Mine was set on AUTO and calls were delayed up to 4 hrs. When they changed the channel (to 11) my phone worked as it should. May not be your problem but something to try.

As the problem happens randomly, I can not tell exactly what may cause the issue.
Changing the CSC or flashing another firmware is a good idea to eliminate all software-related issues.
If you want to change the CSC, install Phone INFO ★Samsung★ app > Menu > Other Tools > CSC Changer.
(Note: That feature requires root to work).

Flashing the stock firmware and changing the CSC will not trip the Knox.
However, changing the CSC may need root to work. If it requires root, make sure to use a root method that does not trip the Knox.

Calls went to VM, the phone never rang. I wouldn't receive the VM for up to 4 hours later. Messages were delayed, I did not receive the message for 30 minutes from the time the person sent it to me until it finally showed I had a message.
I know it sounds crazy that the WIFI could cause a problem but it did.
Turning off WIFI on my phone did not solve the problem.
When I powered off the router/modem in my home my phone starting working correctly.
Something to try, hope it helps.

I know it sounds crazy that the WIFI could cause a problem but it did.
Turning off WIFI on my phone did not solve the problem.
When I powered off the router/modem in my home my phone starting working correctly.
Something to try, hope it helps.

Galaxy S5 G906K
Hi,I have exactly the same problem and I can not use the mobile because of this.I leave in Cyprus and I can not hear the person who I try to speak with,sometimes in the middle of conversation,sometimes from the begining or I can speak 5 minutes without any problem.Seems like we have to make some setting for Europe inside in the phone with ☆#0011# and the phone to be rooted first?

This is a problem,if we rooting the phones we losing the warranty but it looks like is no other possibility to escape of our issue.How else?

Galaxy S5 G906K network incompatibilitty
Well,we found out what the problem is with hearing issue while calling.Is comming from the incompatibilitty of the phone hardware network and each country networks providers.Let me explain:Galaxy G906K Lte has only 3G and Lte(4G)networks build inside.So,if you are living in a country who doesn't have 4G install yet or not all over and instead have 2G and 3G only,and this 3G it does not cover all the areas,then when are you not in the 3G antenna area you"ll gonna lose the reception because this type it does not have 2G old GSM network build inside.That means we can not use it in 2G base network countrys.I hope I helped anyone who have this type of galaxy mobile phones.

Unfortunately I have understood you explanation, but before buying it I clearly asked to the seller and they made me sure the device would have worked as well: who told you such this explanation? What site did you buy the S5 from?
Many thank
Loris

Get this
Who told me this?Nobody, is very simple:go on Settings>More networks>Mobile networks>Network setting>RAT mode setting and you will see there Ltd network and 3G network,NO GSM network(2G).So,all the mobiles from Korea are for Korea and other country's which have 3G or Lte(4G)networks.For example Korea have ONLY Lte network. That's why is for Korea and this phone was named Galaxy S5 Lte-A. You must ask refund!

[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

Factory reset your device then. This look like hardware problem anyway

I already tried that too, factory reset, clean to install New rom, and no luck...
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
