That's nothing more than HTCDEV unlocked bootloader! When you flash a Rom, prepare to flash the boot.img seperate! You should really re-lock your bootloader and root properly. That big pink "UNLOCKED" has got HTCDEV unlocked all over it...I wouldn't do this people!....
Thank you raphael888 for your post. This indeed works. Here is how I verified this is more than just the HTCDEV bootloader unlock.
First I just did the HTCDEV bootloader steps. Then installed Root Check from the market. Root checker verified the phone was still locked although the bootloader was unlocked. The system security status was S-On
I then continued your steps to the end. I then checked the phone with the Root Check. This time it said that I have root privileges. I also loaded Root Uninstall. I was able to give SU authority to system apps. The system security status is still S-On. However it appears I have SU access.
So your steps gives the Super User ability. You may not be able to flash the ROM. However if your goal is to be able to have greater control over your phone this is much better than the HTCDEV Bootloader Unlock.
This is EXACTLY HTCDev bootloader unlock, and you don't know what HTCDev bootloader unlock is. Or should I clarify: this is EXACTLY the rooting method that involves HTCDev bootloader unlock as one of its steps, referenced as "HTCDev unlock" just like other methods are referenced by the main step in multiple-step scheme ("gfree" or "root.sh"), which isn't a method of choice and isn't suggested to anyone but those who only want root on stock ROM, thus it didn't receive a sticky of its own.
Many usersdon’t see any particular reason to change out the stock firmware … more
