Hello there !
I have k850i(vodafone brand) and i want to debrand it.I also need to keep romanian language in it and i need some help and some answers.
First question is :Does the latest firmware contain Romanian language and if so can you post the link to it?
Second one :If i instal this firmware i can delete those stupid demo games for example?..In the present state i can't do it it won't let me.
Third one:If i instal this firmware can i instal elves/elf files(I dont't know exactly what their name is ).
Please tell me what software I need.Sorry for my english if i have some mistakes :D.
