Maybe you could tell us what you have tried and what the symptoms are so we can help more. The updated instructions in the first message of the thread

seem pretty easy to me.
As far as the SD card goes, connect the phone to usb, start adb and type:
fastboot oem enableqxdm 0
fastboot reboot
Granted the USB one is a bit more complicated but let us know a bit more so we can help.
