Exclamation [Q] NEED HELP! My S4 doesn't like ROMs above 4.2.2. WHY ???

Hi,

It looks like my phone doesn't like ROMs above 4.2.2. All the ROMs i flashed, have a signal problem and occasionally, the WiFi doesn't work.
I've tried to change the modem but whatever version i try... i cannot change it. My baseband (XXUBMG7) is the same.
Now i have flashed via ODIN (as a last resort cause i didn't know what else to flash or try) and lost root and all, the official version available for my country (Romania) hoping for a resolution but... no chance .
As you can see in the picture... when i turn the screen on, i have no signal. Tho i can receive calls when my screen is off.
After a while my signal appears and i can make phone calls.
I can's stay like this... please help! Any suggestions ?

Okey listen mate , Download and extract this file http://www.mediafire.com/downloady/kyx5khowhd7yzel/I9505XXUEMKF_MODEM.zip When your done "Turn Of your Phone manually" Remove your battery for 10 sec and put it back ! Press and hold Power+Volume Down In order to reach Download mode , Open odin select Phone/CP (Find the file you extract) put both cable and (check odin if it says com4 with blue color on it) press start and let it do its job , once done your phone will reboot and remove the cables.Now go to your phone setting > More> Device info> and check the baseband if it change. Have a nice day.

when you are flashing a modem, flash twice the same modem and then reboot manually
