adb shell cat /sys/class/mmc_host/mmc1/mmc1:*/cid
A code will be displayed that you should note down. Please make sure you make no mistake writing it down.

- Run the Hex Editor (Run as Administrator if on Vista or Windows 7) and click on the Extra tab.
- Click on Open Disk.
- Now in Physical Disk select Removable Disk (your SD card you just put into the computer) and click OK.
