I was searching the forum, and find way to rot it, it work, it helped me to delete stupid system aplications. Still it show up yellow triangle on bot, but work at last.
I have two question
First: Is there any way to add custom language, i wish to add Serbian, i have only Japanes, English and some on wired letters, guess it's some Japanes.
And second: Is there any way to change this room to official Galaxy S2 room, on bot it show up some NTT DOCOMO image.
