today, I am doing it all over, but encouraged a problem.. After I entered the "5. type "adb pull /sdcard/mmcblk0p4," it showed "c:\Android\platform-tools>adb pull /sdcard/mmcblk0p4 remote object '/sdcard/mmcblk0p4' does not exist" what's the problem??
You must save or rename mmcblk0p4 to mmcblk0p4MOD. Read carefully instructions.
