GT-I9500 dropping from H+ to 3G and not going back

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.

[Q] i9505 Network issues / 3G only

Hi there
I currently have a network problem with my S4.
Everything works well : I have a good 3G, but each time my phone goes on sleep mode, i have a network issue : the network switches off and I have to switch to 2G mode only to get my network back !
I've already tried to change the modem via Odin without success.
My S4 is running 4.3 STOCK SFR and has no OTA available, KIES does not find any update too.
The only way to have a stable network is to switch to 2G mode only, this issue occurs in "3G only" and "3G/2G auto" modes.
My device is not rooted but I was thinking about it to try a custom rom.
Thanks a lot, and sorry for my bad English, cheers from France

- You have one big update: HERE. You can download it and flash it through ODIN and bye bye problems.
- It's normal that your device don't detect any update coz you was trying to change the modem. Your device changed of OFFICIAL to CUSTOM state maybe.
- You have to use KIES 3 (no KIES) for receive the updates of android 4.3 and android 4.4.2.

910F Network Problems

Hello, since a few days my Note 4 has the problem that it looses connection. WiFi works perfect but mobile data and normal signal are gone at least once a day and the only thing that helps is to reboot the phone.
Is this an OS failure or a modem failure? If its a modem failure where can I get a new one for austria?
Thanks for the help.
Edit:
Tried some modems from here for the 910F and now its totaly broken. I have no signal at all, Baseband Unknown and when I turn on Mobile data it says that i have to insert a Sim Card and its restarting a few minutes after its turned on.
Edit 2:
Flashed an update from my operator and its working again, but on the downside I have the operator**** back on my phone again.

Okay it didn't help. Its loosing signsl again and can't reconnect it also has mocrofreezes now.
Is there really no one that can help?
