as suggested in the above post, in the thread it explains, that after you flash the RUU,
You must first RE lock the bootloader
this is done by this method:
su (if needed to get a # prompt)
echo -ne '\x00\x00\x00\x00' | dd of=/dev/block/mmcblk0p2 bs=1 seek=33796
(i would very strongly recommend you copy/paste this)
(exit a second time if you need to to get back to a normal > prompt)
adb reboot bootloader
verify you are now locked (if you can still see on the screen?)
Then you may do "fastboot oem writesecureflag 3" to put S-ON
