I have the same problem, Not 3g at all, only EDGE, even my APN is right and full signal in my town. All my problem begun after flashed my SGY, i lost my 3g. Nobody yet has the solution of this issue, i dont know what to do.

Upgrade !
Just flash your phone if really necessary but if u will just upgrade through Odin , I Suggest you updating firmware via Samsung Kies or OTA(Over-the-air) Upgrade in Settings>About phone>Software update(You will sign in for a Samsung account so if you do not have a Samsung account,Sign up first)
I Just flashed my phone through Odin because i downgraded my DXLA1 Firmware to my factory firmware "DXKK4" , But i didn't encounter any problems as my 3G Network is still working . For me flashing through Odin is Scary for me but if you will study what will you prepare before you flash , Then u will success flashing

[Solved] GPS problem ...

Hello people.
I have a problem on my GS4, everytime i want to use the GPS, it can't locate me at all, it says : "searching for GPS signal"
Everything is activated (GPS, Data, Wifi) as it should be.
When i boot my phone, it finds the signal, but it drops it like 5 minutes later and the only way to get it back is to reboot my phone.
Any idea how i can fix this ?
Thanks in advance :victory:

Well problem solved in two steps :
1st : i've tighten up all the screws as seen on this post (yes it was for the GS3 not the GS4 but it was worth a try)

Hi man. People keeps telling you to install new modem, kernel etc...but i think you have corrupted EFS folder.
I hope you backup your EFS folder before flashing ANY rom because, otherwise you will have to go to some repair shop.

Well, I don't understand a lot, but I think you could check if you didn't lost your IMEI. Go on Settings > About Device > Status and check if your IMEI still there.
If it is, I don't know what could be. You could try flash another modem or restore a backup (if you have one) with PhilZ Touch but if it isn't, that means you lost your IMEI. I remember I read about that somewhere, that there is a risk of losing IMEI when you flash a lot of ROMs.
If you have backup from your IMEI, just restore it. If you don't, I don't know what you could do, but I guess you could still do something.
One more thing: Wi-Fi works?
Like I said, I don't understand a lot, so everything I just said may be very stupid. Or not. Sorry for bad english.

Hello,
I answer here to help also someone else in case has the same problem.
Fiest thing: you wrote CDMA module, what variant is?
The GT-I9505 has a LTE/WCDMA module, not CDMA.
Have you touched something with secret menu codes? If you don't know what they are, the answer is no
What carrier do you have?
Have you roaming enabled?
You data plan reduces connection after a total GBs used at maximum speed?
Try to flash latest available modem fw along with latest bootloader, you can find them here

Thank u for ur reply,
First you are right I'm talking about the LTE/WCDMA module, and yes i messed up a little bit the with the secret menu codes but only after i got the issue, not before that.
I'm from morocco so the carrier is a moroccan one called inwi, the carrier does not reduce the speed, when u consume the GBs given the service is suspended.
the issue appeared when i was using wanam lite 3.1 i'm using wifi at home all the time so i couldnt notice until i went out and used data, i noticed that i only have edge in locations that used to give me H+, so when i tried to force wcdma by choosing wcdma only i got emergency calls only.
i messed around before with a couple of bootloaders and modems, I still cannot figure it out
your help is appreciated, thanks in advance

I had the same problem on Wanam. What solved it for me:
Use Shortcut Master (lite) to go to this menu: 4636
Then go to phone information and change the bandwith to something else. Then set it back to LTE/WCDMA or whatever works for you. Strange but it worked for me.

Get the network cable changed or change it yourself.
The only easy "non software" related solution.
Or maybe if it is in the software, tried flashing the stock rom or any ither custom rom after a full wipe.
Mine was with the stock rom but ozcan rom + data wipe has solved it..
Not i get H+ in only wcdma amd E/H+ in auto mode. (depending on the network area)

I rooted it wrongly and someone interfere and make stupid things using root explorer . i did not install custom recovery .
after figuring out the problem . i installed stock rom and then i rooted it probably then installed cwm custom recovery . after that , someone told me that i should install and try some modems which exists in sweet rom for N910C , i tried many of them but even that nothing happens still the fake imei and fake serial .

Any one!! some help plese....... urgent

help?????......

same problem now as mine my IMEI just became 350050500009692 /01 emergency call only why???

some nice paper weights at least lol none of you have efs back up ? tried restoring it if you do common rule with samsungs all ways back up you efs folder

the sad thing there is mine I don't have my backup

Try NV restore (If you have it Pre-backed up on your phone from factory- at least mine did not have on the N910C but it existed on my N910F) ... Dial: *#0011# , then Menu>Back, then Menu>Key Input> then type Q0000.
After that I don't know where the NV backup is (I forgot, and I don't have the phone now), but you should be able to search here on xda or google it up...
I hope your Exynos has a NV backup....
Good luck
