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 :crying:.
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 ?

- Install Custom recovery (CWM or Philz Touch or TWRP) with Odin
------------
- Open Odin
- Shutdown ur phone and go to Download Mode
- Untick Autoreboot
- Flash modem -> HERE via Odin (button PDA/CP)
- Take the battery off and put it in again
- Reboot into Download Mode using (Vol Down plus Home button combi) again
- Flash Modem once more
- Once done, unplug then reboot device manually (Take the battery off and put it in again)
- It will change ur BASEBAND

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