Hey just was noticed this :
dingoo888.cn seems to have release numerous files today including a new firmware (1.3) i'm not certain if they just reuploaded the files today or if they are new. I flashed the 1.3 firmware but i can not change the lanuage anymore, still checking out the other hxf files (one is in spanish looking at the filename)
There also seems to be a new unbricker tool in the downloads (havent tried it out though) but could be this one fixes the unauthorized message as well.http://www.dingoo888.cn/index.asp
, look at the chinese download section ...
