I've recently bought an Acer Z5 in Netherlands.
Unfortuanelly, I did not check the language pack inside, because I've thought that every phone with Android is multilanguage, no matter where it was purchased.
The thing is that phone, does NOT have Polish language inside.
So, the system is in English, Russian, Netherlands etc.
I've trying to change soft to one from Thai countries but still no luck..
But, when doing backup of firmware, there is a file called system.img.
I've thought, if I find a "system.img" with Jelly Bean and Polish language pack, and overwrite my original file,
is there any chance to change that language with that way ?
I mean, If I flash to my phone JB "system.img" with Polish language, does it help ?
It is possible, anyway ?
I don't wanna brick my phone, so I've decide to ask first ;]
Maybe there is a easier way to do it ?
Any Ideas ?
EDIT : Ok. I should ask Uncle Google first.
Set Locale and Language from Google Play.
Install, add, forget.
Way more easier than flashing entire system xD.
I'm leaving this post for futhure reference.
EDIT 02 : xD. Well....Problem still exist :P. Program does NOT work on Android 4.2... So, is there any way to add language pack into my smartphone ;] ?
