So this is for the rooted users who recently accepted the OTA update to 5.5.893 and found themselves without root and no working method to re-root. This was based on a basic idea of mine that was confirmed as working by OrdieSep88. The credit for pretty much everything goes to dhacker29, 0mie, and dch921 from RootzWiki for providing Releasedroot, great instructions and files, and the FULL CWR 5.5.893 file to flash, respectively. Thanks I'm sure go out to others involved who I'm forgetting. Point is I don't claim any credit, but you can pay me by clicking "Like" and "Thanks" a few times, if you wish 
EDIT: It does sound like the 1-click method is working for some people and not for others. I would definitely recommend trying it out first, because if it works you'll save yourself from having to wipe! So go for that by all means, and use my method as a last resort if that does not work

Last resort option (if 1-click fails):
This process WILL wipe your phone. Also I of course take no responsibility for anything you do to your phone.
1. Use the ReleasedRoot tool to flash yourself back to 5.5.866 system. The tool is found here: R3L3As3Droot And 43V3R Root For The Bionic V2.1 - RootzWiki
There are instructions there on how to use it. I believe you want option 1, which will restore, root, and foreverroot your phone.
2. Download this file (thanks to dch921) and make sure it's on your sd-ext: EDIT 12/22 took down my dropbox link, sorry I need the space! But I checked to make sure the one right below is still working
Here's a backup if my dropbox goes down from overuse or anything: FULL_CWR_893_update - Minus.com
3. Download and install Bionic Bootstrap from the market. Use it to boot into CWR. In CWR, install from sd card the file you just placed there before (FULL_CWR_5.5.893_update.zip).
4. Back to main menu in CWR, reboot.
Hopefully this will work, you should find yourself on "stock" 5.5.893 with the updated radio/kernal files, and, most importantly, with ROOT.
Let me know of any problems and I'll try and be around to help.
