In theory you can always download Skate's T card update software from http://wwwen.zte.com.cn/endata/mobile/ . In downloaded zip file is documentation, how to make a T card update (or you can copy on computer image directory with image.bin to your root of sdcard) and power on the phone with VOL_UP+MENU+POWER. Keep until the T card update not starts. If this not works, then you bricked your phone.
