Hi,i've got a pretty anoying problem,my mobile data ain't working on Kitkat or lollipop,but it works just fine on Marshmallow or Nougat.
I tried to flash stock Marshmallow ,but the modem wasn't the right one for my model and i flashed another modem that worked for a while.
It worked until i put a VodafoneRo sim card in my phone and that was it,no mobile data since then..
Anyone got any idea how could i solve this?Thanks.

I have a very interesting story to tell:
I bought my Samsung Galaxy S a couple of months ago. It had Froyo installed (JQ3 firmwar I believe) and wouldn't let me update to a more recent Gingerbread firmware. Also 3G wasn't working at all; tried creating APN etc and asking support to Vodafone (my carrier) and their final conclusion was that my device was bugged.
At this point, I rooted my device and moved to the MIUI rom (gingerbread). Everything was working fine, including my 3G connection! At first I thought that the 3G problem was probably some issue with old Froyo firmware but now I installed the latest JVR Gingerbread stock firmware and 3G is not working again!!
It seems very strange that I can only get mobile data working with a custom rom and noone of the stock firmware seems to work for me ... anyone has any clue on what could be doing this?
So, I'm having some issues regarding my recently flashed XSP C5302.
Model: C5302
Android Version: 4.3
Baseband version: 8960A-AAAAATAZQ-40031007-18
Build number: 12.1.A.1.201
I'm on locked BL.
Thing is, I flashed it as soon as I got my hands on it due to that annoying flickering screen, tried to downgrade it to 4.2.1. It was the first time I did that, so I went through many tuts to get it right.
At first I flashed a .254 rom, and when I entered the About screen, model had switched to C5303. What I did was follow DoomLord's guide to root it, instal CWR and flashed a deodexed .254 rom for C5302(this one: http://forum.xda-developers.com/showthread.php?t=2423625). Everything back to normal.
But then I noticed my mobile data wasn't working, so I thought it may have been fault of the deodexed rom. Sooo, I upgraded it AGAIN to 4.3 using PC Companion, just to find out that the mobile issue was not having the APN correctly configured. Sigh.
And well, I'm now stuck again on 4.3, but at least my mobile data package is working. However, it's extremely slow. I mean, I can see the H and H+ icon, but even on H+ it takes ages to send messages and connect. At first I wondered if the baseband had anything to do with it, but when I flashed the rom I checked everything but Kernel and System, so...
So my question is, is it possible that I did something that "damaged" my mobile data connectivity? If so, could somebody please suggest any solution? I must say, my service provider sucks, so it could be their problem too, and I'm just here crying over spilled milk with no reason at all.
Thanks in advance!
Probably your service provider - I must have tried 100's of custom roms and whilst some have meant that data didn't work, this was caused by buggy software, never damage to the phone.

Yes, I'm pretty sure too, but oh I was so damn worried! Thanks
Hey guys,
in the beginning, sorry for my bad english (native german). I have a problem with my I9295 aka S4 Active. Since the update to 4.4.2, my phone gets thrown out of the network. Wlan and Bluetooth is fine. Now I flashed the official Samsung DOB4 firmware. Yes, I've downloaded the file multiple times, and the md5 sum was always right. After I flashed it, I was very happy because my cellular network was working again, I could make some calls, etc. But after 20 minutes, it started again. No network. Well, my IMEI was null, and to fix it I had to root. After rooting, my IMEI is there again (yes, the right one) and everything worked fine and was still working, up to yesterday. IMEI still there, baseband too, everything seems fine, but I can't get network. I have to reboot multiple times to get it working again, after that it's working maximum a day, after that, no network again . Atm, i've flashed CM12, but the error is still occuring. I'm very desperate, I hope somebody can help me.
I have a quite similar problem:
My I9295 loses service randomly. Happens quite often.
When I try to go to Settings/More Networks/Mobile Networks I am told "No SIM ..."
SIM is in and had been active. Phono tells me I have network reception.
After reboot it works for an hour or 20 minutes or whatever it wants to.
Sometimes it reconnects after a while, sometimes not.
When I leave it on during night netx morning reconnect works only via reboot.
SIM reader had been replaced.
Problem persists with genuine 5.0.1, with this one: [ROM][Official Nightly CM12/Unofficial CM12.1][5.0/5.1.1] builds for I9295
and WizCyan ROM.
Any suggestions?
BTW I use a TWRP recovery
Possible reason explained here

Enjoy
Thanks for the hint.
Not sure if I get this. The problem was also there with the genuine Samsung ROM (lolipop)while the thread talks aout losing modem function after flashing custom ROM.
About previous I am not sure as I bought it used with 4.2.2 on it.
I updated to 4.4 and then 5 OTA, all genuine.
Only because the mobile kept on losing network I switched to custom ROM, but the problem persists.
At the moment I use the Pac-Man ROM 5.1.1 where it seems to be more stable.
Strange!
@augek
The linked thread isn't only about custom roms - you can end up with partly flashed baseband on genuine if you don't power off before download mode and flash using Odin.
Was the replacement job of SIM reader done by a qualified person?
Following your Suggestion i flashed the genuine lollipop with odin. Yes i switched of Prior to flashing.
And Yes the Person Who did the card reader Job is qualified.
Still the Problem persists.
So to me the question is if the Firmware (driver) is the Problem of my sim card. The sim i tried on my s4mini and doesn't cause Problems so far as far as i noticed.
P****es me of somehow.

hey,
I did, the WiFi and sim is still not detecting no matter which ROM I flash...
My XT1608 stopped detecting SIM cards all of a sudden. The same SIM cards (cropped and official) are working with other devices. It was running the latest build of Lineage OS but reverting back to stock Marshmallow doesn't solve anything.
