Hello Guys,
I've just obtained my Samsung Galaxy Ace 4 LTE (SM-G357FZ), but it is network branded (by "Plus", polish operator) and I'd like to flash it with the oryginal, unmodofied stock Samsung Android, but I cannot find any firmware on the web for that model. The current version is 4.4.4 - G357FZXXU1ANH7.
I've checked sammobile.com and have found only one Galaxy Ace 4 LTE model which the sotware for is valid for Poland, but it is not for SM-G357FZ, but for SM-G313HN and the firmware version is 4.4.2. So can I flash the phone with that firmware using Odin? I'm not sure, because it seems like it is not the right firmware.

Thank you for your assistance .

EDIT:
Something has just appeared here -> Firmware archive | Samsung Updates

I hope it's not branded, clear stock ROM..

EDIT2:
XEO version is there. I will try flashing in the evening.
