For some unknown reason the Samsung Galaxy S4 Mini (GT-I9195) I bought in Switzerland is actually a Polish version, i.e. that's the default locale which I cannot uninstall and that's why only today I was offered an OTA to
I9195XXUCOD3 instead of
I9195XXUCOA2 back in February. While my question basically boils down to
can I simply download the Swiss firmware image and flash that via Odin?
I'd prefer a general (not device-specific) answer for the following points:
- How to figure out whether the firmware and device of two different countries are compatible (e.g. is the hardware sufficiently identical/compatible)?
- how to modify the device's nationality, i.e. is it sufficient to replace the firmware or are other steps required?
- does having the device rooted help/hinder?
