[Q] s4 problem modem - Galaxy S 4 Q&A, Help & Troubleshooting

Hi
Recently I upgraded my S4 i9505 from 4.2.2 to 4.4. 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: I9505XXUGNG8
CP: I9505DVUBMG1
CSC: I95050XXGNG2
MY COUNTRI IS ROMANIA
Could you please help me with this problem. Thanks!

What modem do you have? did you try a different one?

Did you buy the phone from Romania or another country? And it is carrier locked?

[Q] getting low signal and slow internet

Hello, when i bought my samsung galaxy S4 i9500 it was originally UAE XSG version,
PDA - i9500XXUBMEA
CSC - I9500JVBMEA
After flashing omega v8, my phone started getting lower signals and slow data speed. I was told to flash a modem from this link:
http://forum.xda-developers.com/showthread.php?t=2192025
Would anyone happen to know which modem i should flash from the link? or should i test them all out?
I also noticed my Mobile Network type is: UMTS:3. Before i think it was HSDPA:9.
I live in Australia if that helps.

[Q] I9505 lte annoying shutdowns

Hi Xda.. im following you for 3 different devices (gs3, xperia z, and now gs4).
i ve a problem with my s4.. originally it was a branded h3g (im italian) i9505 so i decided to make it no brand..
so, installed the phil touch recovery i choose the "android revolution hd 3.0" based on xxubmga firmware + wifi fix..
at this point my s4 begins to shut down suddenly during use.. always when the % battery is at 69% or lowest..
I realized that the baseband remained I9505XXUBMEA that of my old branded firmware (h3g - PDA I9505XXUBMEA CSC I9505HUIBME3 MODEM I9505XXUBMEA)
so i installed with odin the modem of xxubmga of android revolution hd 3.0 but the problem is not solved.. it he shuts down unexpectedly.. when im using whatsapp.. chrome.. etc..
now i used the code *#1234# and i saw AP I9505XXUBMGA CP I9505XXUBMEA (so it s not changed also after odin's replacement modem process) CSC I9505OXXBMG4
how can i fix this problem of shutdown? is a battery problem? or rom problem?
thank you.. and excuse me for my bad english

Check if there is any lump on the battery or you can try a friend's battery if he/she has an s4.

You're from Italy? What's your original CSC? If you change the baseband and the build, your CSC needs to be the same as the original because the CSC handles the communications with the operators. It won't work otherwise.
Now I don't know why that would cause shutdowns. Try changing your CSC. And then try a different battery.

Change battery as the first thing. Also you need to make sure that your Modem is same as the base, so flash a ME3 modem.
