I am also experiencing that. First I've flashed GRI40.zip Rom which I've thought that is my original rom,then I succeed flashing it in recovery mod using clockworkmod but the problem is , The Screen is black ,"Application settings unexpected stopped" It pops like this, I can't go to recovery mode,and My computer(xp) cant read my device..
Help please I'm begging . I Don't want to be embarrased :'(
