I've successfully rooted my Droid RAZR MAXX HD with stock firmware version 9.30.1, but I can't seem to figure out how to unlock the bootloader.

The one catch with my phone being rooted is that it always ends up in fastboot when it boots. A simple
Code:
fastboot continue
fixes the problem, but I was wanting to flash CWM Recovery to install CM.

I have a working su/Superuser.apk, but I can't seem to fix the bootloader dilemma.

Okay... I also have another wonderful problem: my phone consistently gets into fastboot mode upon startup, with my current workaround of doing fastboot continue. Is there any way to fix my currently locked bootloader?

As Jhal said, you can't "fix" your bootloader, it's locked since you're on the newest OTA and it can't be unlocked. With that being said, your phone is not booting into fastboot because you're rooted. It's booting into FB because you tried to flash something that didn't work. What other things have you done or attempted to do, besides rooting? This will help us help you, the info you provided is pretty vague.

I have done absolutely nothing beyond rooting it, installing Superuser & SuperSU (both through a script I can attach, but I'm on the wrong computer), and backed up a slew of apps.

This first begun when I modified the script to fix a bug in it (ash in JB 4.2 doesn't have a -f switch in rm, and the script had a 'rm -f'). If that bug didn't exist, then it would've still happened the first of several times (I attempted it about 4-5 times, but only the last caused this). The rm -f was actually doing effectively (with successful root privileges) 'rm -f /system/install-script-2.sh', but the script actually had another script to be put into it at the location /system/install-script.sh.

Start by detailing steps in your 2nd paragraph.
Your boot is locked if it was never unlocked before you upgraded to ...79 or later

Looks like you either flashed a fastboot or used a tool that used the command "fastboot oem fb_mode_set" which causes the phone to boot directly into fastboot mode. It can usually be fixed with the command "fastboot oem fb_mode_clear".

Didn't work. It is still booting there on its own upon start-up.

Also, I will mention that I did commit an act of stupidity: trying to flash against a bootloader that I couldn't verify was unlocked yet. I stupidly ran the command when I wasn't even 50% sure that it was unlocked yet (and is likely the cause of all my problems):

Code:
fastboot flash recovery <cwm-file>.zip
I'm trying my hardest to avoid sending this to Motorola just for them to charge me for the replacement, saying I've voided any warranty that exists with the phone. I have the original firmware to flash just in case, but I don't have the Motorola fastboot (for the dev editions).

First, there is no Dev Edition Fastboot....the closest would be Bell ICS since Bell shipped unlocked/unlockable Atrix HD's.

You don't flash zip files with fastboot flash.....Why is this becoming an issue these days?* The kernel is "fastboot flash boot boot.img"

*just thinking out loud

EDIT: Just realized that this was the RAZR HD forums.....just replying to quoted posts this morning....Not sure about RAZR HD Dev Edition fastboots....

The shame is, I never cared about unlocking the bootloader, as I prefer to stick to OTA's, but I do require root. So that's all I've ever done. I'm successfully rooted with the locked bootloader on 9.30.1, but it seems (at least as far as I've read on here) that I'm stuck there as I can't go anywhere else and maintain root. Would love kitkat, but root is essential.
