I only can to the downloading mode.The main thing is this, I upgraded a wrong files contains "boot.bin" and "sbl.bin" ,when i reboot it can boot but only sound no picture, I think the problem is voodoo then I go to the sdcard voodoo folder, add the disable-lagfix to uninstall it , then can not boot up.
