Here is your SD flashing Method (I copied this from my help tutorial):
Flashing your device using the SD method. (For Vogue Device)
1. Card has to be 2gb or less in order to work(not SDHC).
2. Has to be formatted to fat32. To format place the card in a reader and insert reader in your PC. Find the drive that contains the card. Right click the drive and select format. Under file system select fat32. Hit start. Once the format is complete the card is ready to use.
3. Place the file you wish to flash on the SD card. Rename the file to VOGUIMG.nbh.
4. Remove the card from the card reader and insert it into your device.
5. On your device hold the power and camera buttons then reset and continue to hold power and camera till tri color screen appears. The device will then load the nbh, and a grey screen will come up that asks you to press power button to begin. The flash will take around a minute or so. Once the screen reads update complete you need to press reset and the flash should be complete. If you are flashing a radio the device will boot up normal. If you flashed a ROM the phone needs to be hard reset. Press the send and end keys on the front of the device, and hold them down while pressing reset. Continue to hold the send and end keys down till a grey screen comes up asking for confirmation of a factory restore
You can cook a ROM and do the flash with a cable or you can cook the ROM and pull the RUU_signed.nbh out of the kitchen and flash your phone using the SD method.To locate the file that you need from the kitchen go to My Documents\BuildOS RUU and select the file titled RUU_signed.nbh. That is the file you need to place on the SD card to flash.
