Default [Q] Samsung I9505 LTE Help choosing correct modem (4.3 connection problems)

Hi

Recently I upgraded my S4 i9505 from 4.2.2 to 4.3. Earlier I used Wanam Lite custom rom and now Omega rom.

I faced problems with my phone:
- there is connection loss and problems with wifi (wifi connects and works but it says connection is unstable)
- there is connection loss and problems with 3g/4g (h/h+).

I wonder if I'm using correct modem. I tried searching this forum and google, but didn't manage the find the correct ones.

AP: I9505XXUEML6
CP: I9505XXUBMF5
CSC: I9505VFGEML1

I'm using Omega v19 - XXUEML6. Baseband I9505XXUBMF5

Could you please help me with this problem. Thanks!

I downloaded the file, then I put phone in to the Download mode, started Odin. Unticked the "auto reboot" option, selected [v] Phone and file I9505_XXUEML6_MODEM.tar. Then pressed start.

try this mate Make sure to turn off Manually your phone "Press power button and Power off" because it wont work if your doing Press power >Restart >Reboot option >Download !

Untick Autoreboot
Flash modem by slecting Phone/cp
Reboot once again into Download Mode using (Power+Vol Down button combi)
Flash Modem once more
Once done,unplug then reboot device manually.
If this doesn't work, try repeating the flash process again while rebooting manually and with auto-reboot option turned off.

I made this three times. For the 4th time I couldn't get to download mode, maybe I mispressed the buttons but, not sure...

Then I rebooted and checked *#1234# and THERE IT IS: XXUEML6!

I also tried to lock and unlock phone, and the H+ connection stays. I also tested with Signal Reset application which makes notification sound when there's signall loss.

Thank you Repulsa!

This topic helped me also.
I had the same problem with the signal loss on several ROMs. When phone screen is on, I have HSDPA/HSDPA+ signal, but when screen goes off, and you turn in again - there's no signal anymore. I had to go to network settings to choose network again, and it works... ... till screen is on.
I temporally fixed problem when I turned on GSM signal only.

With this solution, I have permanently fixed my problem.

Thanks!

I have the official rom by Samsung based on Android 4.3:
AP: I9505XXUEMJ7
CP: I9505XXUEMJ7
CSC: I9505ITVEMJ8

And I have the same issues about connection lost... Can I install a better modem without losing warranty? Or can I do something else to avoid this issue?

Thanks.
