# goldcard: (Guhl and Nipqer) part of the commands are in http://www.thinkthinkdo.com/trac/project1/wiki/nipqer
                # we might want to flash the pc10img with fastboot to avoid writing to the sdcard while it is golden
                # BACKUP the sdcard prior to make it golden

        # 1. get the cid
                cat /sys/class/mmc_host/mmc2/mmc2:*/cid

        # 2. reverse the cid, paste it into http://psas.revskills.de/?q=goldcard , get the img by e-mail

        # 3. temproot (fre3vo or psneuter)

        # 4. adb push goldcard.img /data/local/tmp/
             adb push busybox /data/local/tmp/
             adb shell chmod 755 /data/local/tmp/busybox

        # 5. get an img of the first 512 bytes of the sdcard, check the img for sanity: 
                adb shell 
                cd /data/local/tmp 
                dd if=/dev/block/mmcblk1 bs=512 count=1 of=512.img
                ./busybox md5sum /data/local/tmp/512.img
                dd if=/dev/block/mmcblk1 bs=512 count=1 | ./busybox md5sum

        # 6. write the goldcard.img, check the success of the flash:
                dd bs=512 if=goldcard.img of=/dev/block/mmcblk1
                dd if=/dev/block/mmcblk1 bs=<size of goldcard.img in bytes> count=1 | ./busybox md5sum
                ./busybox md5sum /data/local/tmp/goldcard.img

        # 7. move the 512.img to a safe location
                cp 512.img /sdcard              # (or adb pull /data/local/tmp/512.img)

        # 8. flash the ruu (fastboot)

        # 9. temproot (psneuter), push and chmod busybox as in 4.

        # 10. restore the original 512 bytes and check - same as p 6 but instead of goldcard.img, 512.img should be dd-ed in and md5ed.
                dd bs=512 if=512.img of=/dev/block/mmcblk1
                dd if=/dev/block/mmcblk1 bs=512 count=1 | ./busybox md5sum  # compare that with the md5 from 5.
