    If I unlock my DROID Incredible's bootloader with HTCDev, is there a way to lock it back at any point?

    No I don't believe there is, unless you unlock it through unofficial means first (go s-off)
    I'll look into it further though; it also may mention it on the HTC dev site though.

    Edit: from the website

    But I assume, that even if you unlock the bootloader through this method you would still be able to follow the guide for rooting 2.3.4 and downgrade back to froyo and achieve s-off, then install then standard hboot, then follow the process to unroot, BUT I'm really not sure.

    to relock,youll simply use the fastboot command fastboot oem lock

    at this point your bootloader will say **relocked** instead of **unlocked** and it will remain so until you run an RUU that overwrites it.

    re-locking your bootloader with a custom rom installed will give you a **security warning!** that will lock your phone into bootloader and not reboot(read: make unusable :eek:) and remain that way until you run an ruu that is your current firmware or newer.

    i have flashed the htcdev unlock hboot and flashed back to the .92 hboot several times with s-off.

    i would pretty strongly recomend that you do NOT htcdev unlock unless you are s-off first.

    as sdraw said,i *think* it will be possible to follow the guide and downgrade back to rootable froyo,but im not 100% sure. it is quite feasible that this hboot will perform checks that prevent us from doing so,and you could be stuck with it forever. a similar situation happend with the evo 3d,and they still have not figured out a way to downgrade. :(

    I used htcdev to unlock my Inc2 - only to find that I would have to flash the boot.img for every custom rom I wanted to flash. I tried to downgrade the bootloader AFTER unlocking it, and while everything appeared to be fine, I got an error right at the very end.

    In order to get back to the original state of the phone, do you think I'm going to have to run the RUU before I re-lock the bootloader?

    I'm not sure if it will let you run an ruu until you relock it. If you do that,and it works,let us know. :)

    As you've found out,recovey cannot write to the boot partition. The EVO 3d guys have found that softbooting the recovery from fastboot works to flash kernels and roms with different kernels in the conventioneal manner
