Hello. Im running Kitkat 4.4.2 Goldeneye rom. NBE modem. I am encountering a problem with my mobile data. Whenever I choose LTE/WCDMA/GSM I get a brief connection to H or LTE but after a few minutes (random) it goes away and doesnt return after ticking on/off.
My temporary fix is just using the WCDMA only option. Anyone encountered this problem? Would provide more info if needed. Thanks in adv for your help.
So my lte/cdma mode doesnt seem to work at all, i know i have 4g but when i turn on my phone it says mobile network (under settings) connecting and then the mobile network type keeps flashing from lte to unknown, however if i i switch to cdma mode 3g works fine so does anyone know a fix to lte ? i already reflashed with odin and also restored and did all that (sm-g900r4) i also attempted to do a nanroid restore but that didnt fix it either :/
Hi, I'm from India and have a GT-I9500 which has been running flawlessly for the past 1 year on BSNL service right up to OS version 4.4.2 firmware vers. I9500XXUFNE4. Since then I upgraded the firmware twice to I9500XXUFNG1 and subsequently to I9500XXUFNI2. Midway while using firmware I9500XUFNG1 in rooted version, I started noticing that my phone data would run normally for a while and then suddenly the data connectivity would drop from H+ mode to 3G but would not return to H+ even though I know that I am in an area that has consistently strong H+ signal. The only option to get H+ mode back was to go to Settings/More networks/Mobile networks/Network mode/ and change the setting to WCDMA only mode for two minutes and then switch back to WCDMA/GSM(autoconnect), then the phone would get H+ service back again for a few hours. I thought that it might have been some problem caused by rooting, so when the latest firmware (I9500XXUFNI2) was released this month I upgraded the firmware but since I lost root on upgrade, I did not root the phone, fearing the problem will come back since I thought root was causing it.
Now in stock firmware running on I9500XXUFNI2 I am still getting the same problem of the phone dropping to 3G mode from H+ and not reverting back ( the speed is not even 2G. Just the 3G icon shows it - data packets hardly get transferred) and I can rectify it only by switching to WCDMA mode and back to autoconnect, as previously stated.
I checked online for solutions, but I don't seem to see anyone facing such an issue.
I thought it could be a service provider problem, so I used SIMs from Idea and Airtel as well, but while using those networks also, the same problem persists, so I have deduced it is a problem pertaining to the phone only. Not sure if it is a hardware malfunction or firmware based.
Does anybody else from India running the latest firmware for GT-I9500 have similar problems, and is there a solution?
Thanks.

The problem is with the modem firmware. Change it back to the original or get a kernel.

Thank you, Devilslasher. Could you please link me to a thread where they have listed the original modem firmware? I did a search under the Samsung S4 subsection on xda but could not find any thread where modems/radios for Indian version was hosted.
Thanks in advance.
As the title says: I reverted from marshmallow back to kitkat, but lte doesn't show up, only 3g. When I am on MM again, I do have lte signal on the same place. Also in the system settings I dont have the lte option on stock kitkat. Any advice on how to get lte on kitkat? Or is it a problem only on my phone (I do have the G900F so it is lte supported)
Okay, problem solved
I needed to check the right option it in the service mode and I updated the right apn.

After a reboot it is also written in the system settings.
After reverting back from RR 5.8.0 to Stock kitkat my phone is not getting 3G/4G networks although I've activated 3G/4G plan. It's only catching 2G networks. Network drops regularly and phone goes to "no service' for moments. Any solutions?
Thanks in advance.
U might not have edited your APN settings.
Search on Google for APN settings of your sim operator, edit it and save it.
If your problem is solved plzz hit that thanks button..
No everything is okay... 2G network is working.. but not getting 3g /4g network.. when the preferred network is set to 3g only.... I restored modem files.. and flashed stock ROM through QDloader mode.. but nothing is solved..
