My s4 is rooted. The problem is that after some flashing of custom roms my 4g/3g is not working properly . In other words, in all roms above jellybean ( kitkat and lollipop) my LTE and 3G is working only for 1-2 minutes and then my signal drops to zero no signal at all. When i switch to GSM signal comes imidiatelly to full! I have searched a lot in this forum , I have tried many times to change modem , CSC using ODIN ofc, but no succeess so far.. I dont know what else to try or to do differently...I also tried to flash the stock modem but still no success... I would like to add that in 90% of roms that i have tried so far my WIFI , and everything else is working normally ... My only issue is what i had mentioned before...PLZ help me.. I DONT KNOW WHERE TO REFER TO IN THIS SITE...
May be you need to set APN (Access Point Names) for your mobile service provider

I think you have a big misconception about what this site it. It's not a helpdesk. It's people helping people and we are not forced to reply.
You have the losing of the signal also on stock Lollipop roms?
Setting APN is not a switch though, you have to put in settings that your 3G/4G service provider uses. Either search for the settings on the Web or ask your 3G/4G service provider for the settings.

As i have stated above i use a rooted galaxy s4 and of course my rom is custom lollipop ...with reference to apn settings , i know what they are and i will say again that the settings are ok i have checked it. The problem is that in custom roms above jellybean i encounter the following network problem . 3G/4G is working properly for 1 minute the most and suddenly signal drops to zero . Only if i switch to GSM will the signal be up again ! Anyone any ideas?Same problem with kitkat roms and lollipop. Installation is always correct . But i dont know ...

I kind of just saw this in the "unread" tab here on xda, so first I would like to apologise for replying without having your device. But, the only thought that comes to mind is a baseband/modem. Not sure if the sgs4 has flashable modems but it would definitely help if you guys did.

I also use a rooted galaxy S4 but model GT-i9500 I have the same problem as you,
can not connect to 3G/4G network with kitkat and lollipop based rom.
All I had to do to fix it is to set the correct APN settings for my 3G/4G network
just make sure that the modem you are using is the same one as your new rom is based on,
I have to do this every time I flash a new rom....
well i dont know but it all seems complicated . I ll try guys !!! Another question to those who have galaxy s4! Is it my misconception or all the roms above custom jellybean make the S4 slower?? Lollipop Kitkat are ok But exept of the Google based( pac-man , cyanogen, paranoid etc..) all the touch wiz roms are slower than a custom jellybean ...

Okay, so its been a week since I got a Galaxy Note...
I haven't rooted or anything and its running no the firmware is "XXKL3" and baseband is "N7000DDKL1"...
The phone was working completely fine until today morning, whenever someone calls he gets "The number you have dialed is out of coverage area"....
While out going calls work perfectly fine.
So I removed the SIM and put in Vodafone SIM which worked fine in Note....
Then I put the non-working IDEA SIM into another phone and it was working fine too....
Then I put the IDEA SIM back in the Note and I once again had the same problem.
I tried a hard reset from recovery but that didn't work either
Has anyone experienced the same problem?
Any solutions?
On a side note if nothing works out I am planning to flash the phone but the HotFile link for "N7000ODDLA1" is not giving me speeds more than 30 KB/s.... -_-
So, has anyone mirrored the firmware to another file hosting site?
If yes, can someone provide me the link?
If vodafone works n idea not working, means service conflict is there. Check call setting.
Latest version is ddlb2
Go to dev section n find my thread n7000 stock roms, it is sticky thread.

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

i have been doing that for almost so many time, i cannot even count how many times i did it, i also tried different CSC and stock roms (from doky) and still i do not have 3g. I did also tried fully flashing my phone and up to now, no luck....:crying:
Tonight I installed KitKat 4.4.4 (tried 2 different 4.4.4 roms) on an i9505 which was previously running jelly bean (stock, touchwiz).
The phone network keeps disconnecting on it. If I go into wireless and networks/more/mobile networks/network operators and select my provider through there, it will connect and work fine for a while, but will then disconnect itself again randomly. The IMEI is all fine. This is the first time i've really been stuck with a problem, and i've been flashing roms on multiple phones for a long time.
Why would it be working, but keep disconnecting itself? So annoying..
Anyone able to give me some help here please? Would really be much appreciated, thanks..
Just thought....
My mate whose phone it is has gone away so I won't be able to try this until tomorrow, but maybe it's not a UK baseband on it..
I'm sure I've used basebands before though that weren't specifically for my country on other galaxy phones, but it's a good possibility do you think? I didn't think it could cause that, until now..
I can't believe I never thought of trying that at the time, I'll find out if that is the problem tomorrow.
Solved!!
For anyone experiencing the same problem...
Flash a baseband which is specifically for your country with Odin - WITH AUTO REBOOT UNCHECKED
take battery out. Boot into download mode. Flash the same baseband again. For some reason if you only flash it once and leave reboot checked it doesn't work.
Phone will boot, and you will find that the problem is fixed.
Hope this helps someone else avoid the **** that I encountered.
Thanks!

Nice to see this thread has helped a few people.
I was scratching my head for a while with that problem, and I'd consider myself pretty experienced with android and flashing ROMs.
I was searching the net, and I found forum posts of people saying they had the same problem, I even found posts that said SOLVED!!! in them, with no explanation as to how it was solved lol. Great help.
Anyways, peace all.
And 1eyedmonster, just gimme a shout if you want the one I used and I'll send you it, or pm me your gmail add, whatever..

It was this issue that has stopped me from flashing aosp and cm 11 in the past as as soon as I booted and set up my apps I would lose signal and would have to aeroplane mode on and off before I could regain signal again and the only roms that I could use was goldeneye and miuiandroid miuiandroid
Thanks to you I will probably spend the weekend flashing Mrs won't be happy [emoji12]

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)

Must be something to be done from your network, get 3g activated on your number from helpline.
i'm sure there is nothing wrong with the phone.
