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:

I also tryed that several times but nothing...
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.

Having an issue detecting new wifi signals

Problem - Certain WIFI connections are not appearing on my phone, for example at work. Phone says that there are "wireless networks available" but nothing new shows up. But WIFI connections at home work. Since I have discovered this problem, I cant make "new" connections" basically. The connection at home works because i connected to it before i discovered this problem or I have deleted something along the way.
Usually I am the type that we go thru and uninstall useless programs / services off of my phone. I typically install custom ROMS that take care of this but I havent do so with the Moto X. I like the active display feature and want to keep it. I even go thru with App Op and disallow certain permissions thru out the system (mostly location services).
Can someone please help me. I feel like I could run a backup and reinstall 4.4 and I feel like it would go away but I was looking for a simpler way of fixing this.
Of course I can provide more details if needed.
Currently my phone is 4.4 Stock with root access.
thanks in advance

If you use WiFi analyzer do the signals show up in the app?

Installed the app. I'm currently at home, so i can't truly test it, but my home network and surrounding networks do show up.
Thanks for the quick response btw.

No worries!
That would seem to say that there's an issue with the settings program on the phone and not actually the hardware. Someone feel free to correct me if I'm wrong though...
Edit: have you tried wiping the cache?

i havent wiped the cache yet. can i achieve this within 4.4 or thru a custom recovery. The only time i have in the past, was with SafeStrap or BMM. which i havent installed neither on Moto X

Never seen an option to wipe cache inside the os, that would be something you'd have to do externally. Perhaps someone with a bit more insight can provide a more concrete solution.

Wifi won't connect to open network. Connecting, then saved.

I tried searching this fourm, online, and no results after countless hours.
This is my problem. At work there is one big open network with a lot of extenders everywhere. When I got my new phone phone from BB when I broke my screen I tried to connect to it and it says " Connecting...." for a few seconds then automatically goes to "Saved".
I tried the obvious, forgetting network, rebooting phone, restoring to factory, updating firmware, nothing has worked so far. It always goes from connecting to saved. Every other device has worked flawlessly besides this phone
My last few phones have had no problem connecting. I do not have the authority to reboot the whole system, change frequently, add a pw, basically I'm only allowed to connect.
Wondering if anyone has experienced this problem, and might have any ideas or solutions. This is the only network that has ever gave me a problem.
Thanks for taking your time to read and help!

Funny thing... I just got a brand new galaxy note 3 and it does the same thing... Making me think something with this Wifi setup and the galaxy family phones are not getting along. I'll try and see if I can talk to the Web tech and see if he can tweet something to get it to work.

Urgent Help require: Note 3 “Smart Network Switch" not working anymore.

Hi there,
Recently I discovered this issue: the “Smart Network Switch" is not working anymore.
For me this is very important, as here wifi connection is not that great like the Mobile Data network here. Wifi internet sometime downs without any notification but Mobile data network is 100% uptime 24x7. But so far the " Smart Network Switch" helps me great as I’ve to stay online over skype always, if the wifi lost internet then it automatically switch to HSPDA which helps me to stay online always even if I’m unaware the wifi internet is down.
Earlier even if the wifi internet link is ok still sometime it was switching to HSPDA by saying internet is slow, I don’t mind that but recently I was noticing even if the wifi was down for long time it wasn’t switching to HSPDA.
In short the "Smart Network Switch" isn’t working at all at any condition. I doubt it could be due to any recent installed app. But I’m not sure which one could. I checked the all recent installed apps accessibility list and removed Airdriod and CM Security which had full network access. But still that didn’t help.
I’m sure this is due to a software bug not a hardware issue. For more input and clues:
# Since over last six month my phone lost the vibration, the vibration motor is not working, I tested with hardware test. I’m really not happy with this phone. Its not yet completed 1year and couldn’t find any nearest service center. So its still working without the vib feature.
# Recently I’ve upgraded the local WIFI setup with a primary dual band TP-Link router and another wifi router as bridge with same SSID and password, this is to get better wifi coverage. Due to this dual router the wifi coverage is at full bar everywhere and the phone has the same. But I think this is nothing to do with this.
Please advice. Thanks in advance.

Have you tried a factory reset?
Have you removed the certificates from those apps?
Have you removed them as device administrators?

Thanks for your reply. No I don’t want to factory reset for now, this would be my last option as I have to a lots of work to get everything back, apps and data, setup etc.
No I did not removed the certificates from those apps. Never did this before. When I uninstall I always clear all data of those apps and then uninstall. How do I find certificates of those apps? I know the certificate location but don’t know how to find those specifically.
I removed them as device administrators if its require, if a app in dev admin, it cannot be uninstall.
Please advice. Thanks

Sorry, credentials, not certificates. Bloody autocorrect....
Settings > security. Scroll all the way down. You can either clear all user-added credentials all at once by hitting clear credentials, or look it up and deselect it manually under trusted credentials.
Sent From My Samsung Galaxy Note 3 N9005 Using Tapatalk

Yes here credentials are CA certificates, after reading your 1st post I checked that but there was none user added, all are system and its a huge list. Also the clear option grayed out as nothing there to delete.
I wiped system cache partition from recovery, ran it under safe mode but nothing helps. So I doubt this will fix even after formatting to factory setting. It could be a hardware issue.

The issue has been fixed after formatting and factory resetting the phone.

Yes but this made my work increase a lot to get back all previous apps and their data. Kies app backup didnt backup app data, only the apps itself. I didnt know that. It took me a a day to get every setting back. Their could be another way to clear data somewhere which I couldnt find.

No data.

Help. I bought my note 3 the day it came out. I have been running Alliance build 1 since it came out. A couple of days ago I noticed my phone wouldn't connect to data unless I was on WiFi. The 4g icon stays grayed out. I could still send text messages though. But if I opened the my Verizon app, the 4G icon would brighten and it would connect to Verizon. But no other app can access data, even when the 4G icon was highlighted. So I hoped upgrading to build 2 would solve the problem. BUT NO LUCK. Now I can't send text messages or connect to data. Any body have a clue?

update
So I spent an hour on the phone with Verizon. They said they couldn't find any problems on their end, and we troubleshot my phone and nothing helped. So it is something going on with my phone for sure and not the network. Should I try another Sim card? Should I Odin another modem? Should I Odin back to stock and see if I can connect then to data?

Update
Well, I've tried several different modems. None of them worked. What I don't understand is why the modem will connect when I open the My Verizon app, but nothing else. Leads me to believe there is something software wise that won't let it connect. But it stopped working when I was on Alliance build 1 and that problem carried to build 2. HELP

Odin back to stock and see if still persists. If it does then it's hardware. If not then starting fresh and rooting/flashing the rom should fix.

Please any ideas?
So I Odined back to MJE. Still doesn't work. Odined back NC4 and the modem still won't connect. But the modem/data works. The My Verizon app will turn the data on and connect like normal. There has to be something keeping other programs from accessing the modem/data. Otherwise My Verizon wouldn't connect. Please can anybody help.....

Update...HELP....SOS
So it isn't hardware related. I just turned my Hotspot on. Guess what, the Hotspot works. My wife was able to connect to my Hotspot and use my data. BUT I still can't use it on my phone. Even when she was connected to my Hotspot using my data, I couldn't use data. How weird is that!? Please, help....

Did you actually Odin back to stock firmware or did you just Odin the radio?

I am stumped.
I Odined just the MJE modem at first, didn't help. Then I Odined back to stock Nc4 firmware, did factory reset, didn't work. I've spent hours pouring through every menu I could find to see if there was something not turned on, then I did it again. I haven't gone into service mode yet. I've toggled data/airplane mode/global-ltecdma/anything else I could find hoping it would help. Still no dice. But the Verizon app still connects add well as my Hotspot so other devices can use my data.

Did you try your APN settings? With all that flashing you have done maybe lost your APN settings.

Yeah, I checked them against the settings I have found on the Internet. I couldn't create my own for some reason though. The option is grayed out on my phone...

To add to the confusion, data decided to start working again today. Looked down and noticed it was back on.
