READ THE ENTIRE POST!
DISCLAIMER: By downloading the attached file, you agree that you Revenge Of The PC is not responsible if your phone magically commits suicide due to your cruelty and abuse.But hey, you would then have a hatweight. Do not download the update if you do not know what you are doing OR if you are DRUNK/TIRED because it is highly probable that you will have a free hatweight. In all seriousness, take caution and be prepared. Read the entire post before beginning. If you don’t know what something means, ASK before proceding! Note: You may want to do step 4 first, as it may take a few minutes (if you SBF it can take more than half an hour).A few days ago we posted our mirror for Gingerbread build 4.5.588. Today, we will post the rooted version of the same build with a clear and concise guide to getting it properly installed. Just a warning: if you do skip any data wipes or any steps, I can guarantee you a soft brick. To un-brick, SBF back to stock (see Step 4 or end of post).
1) Download Part 1, Part 2, and Part 3, then verify the checksums here using this tool, which may come in handy in the future. If the codes match, move them to the root of your SD card. You will use them later. If the codes don’t match, try to download them again. If that still doesn’t work, get them from one of the mirrors on MDW. The same goes for the rest of the downloads.
2) Optional: Back up data, apps, etc. via Titanium Backup (or whatever app you chose to use).
3) Make a backup of your current setup just incase anything goes wrong in ClockworkMod (Bootstrapper).
4) Download and flash (through Bootstrapper) DX-Monster 2.3.340.zip from TeamBlackHat app (which was pulled from the Market recently), maderstock.zip from here , SBFing to 2.3.340 (I use this to SBF: http://goo.gl/SVU7l– you can do it with a bricked phone, too, with no setup required), or restoring a 2.3.340 backup. Just get to STOCK 2.3.340 somehow. This means you need the bloat (root is okay though). Once here, WIPE DATA.
5) Now that you are on stock Froyo, you want to download the Droid 2 Bootstrapper (yes, the Droid 2 Bootstrapper) from either the Market or from Mediafire (it’s opensource) Also, download Z4Root from XDA-Devolopers.
6) Run Z4Root and get permanent root. Upon rebooting, run Droid 2 Bootstrapper. Click “Bootstrap Recovery” and then after seeing the success dialog, click “Reboot Recovery”.
7) Once in Clockwork WIPE DATA! Then install Part 1, Part 2, and Part 3 without doing anything in-between. You need to install them all in that order before leaving recovery. After installing them, WIPE DATA once more, then reboot.
You should see a red Motorola logo, and eventually the Droid eye. If you get a bootloader error screen (with Err: A5…. can’t remember the rest), go back to Step 4 and SBF (then try again if you want to, but start from the beginning again). If all went correctly, you should now see “Touch the Android to Begin”. You can now restore your apps or do whatever you want.
ENJOY! 
I’ll post this one more time: this tool is a life saver. Even if you don’t need it, you should download it and burn it to a CD just in case you need it. It takes less than half an hour to use.

Feel free to ask questions here for clarification, but the guys over at MDW know a lot more than I do.
