All tools located at bottom of post. I am in no way responsible for what you do to your own phone.
Anyway, For those who know what ODIN is, think of this as odin for lg phones. You can use these tools to fix your phone if it is soft-bricked, or if you have the wrong cwm recovery installed and cant access adb.

Prerequisites:
Windows
LG United Mobile drivers 1.2.1
KDZ Updater and R&D Tool (included at bottom)

Guide
You use cab's as your image files, using the tools below you have to convert the official firmware cab to kdz using R&D Tool. Once finished you can either use kdz update or the same R&D tool to update your phone.
-For now use the ls855 kdz provided at bottom.
1.) Make sure you run windows enabler first (included at bottom) and click the icon in the task tray (it will say "on"). You also need to install the msxml.msi.
2.) with your phone off, plug it into your computer and turn it on normally. then leave it be.
3.) go to kdz update or r&d tool and click QPST smartphone. Then open your kdz file and click start update.
a.) Your phone will sit for a while and may reboot several times, just leave it alone and it should finish on its own. Never touch anything unless you get an error popup, otherwise it is still working and you could F it up.
4.) Once its finished you should see the Sprint bootanimation, my phone never made it past that point but others has loaded completely. Guess what? adb should be working even on the bootani so run PlayfulGod's AIO root and CWM and run the batch script.
5.) Then you can pull battery and reboot into recovery. Now you are able to flash a boost custom rom over the phone to get it back to normal, or you can restore a nandroid backup posted on the forum, do NOT use any backup you may have attempted using the recovery or touch recovery from the Optimus Black phone.
6.) Profit?

Side Note
Ive also found a method to inject any cwm recovery file any to any kdz file. Just run cwminject 1.2 as admin, setup the files, then get kdz ready, make sure u have the right process in cwminject on the right side for the program you are using. Start the kdz update and then click scan on cwminject and it will automatically inject the recovery into the memory files before it gets transfered to your phone. To use cwminject you need to have .Net framework 4 installed on your computer.
