I'm with Psychokitty... not backing up is bad advice... it limits the options for recovering in the event of a problem and makes the recovery a much longer process. It doesn't make it impossible but it does make a person work harder when it isn't required... and a backup doesn't take that long to perform.
Still... its water under the bridge and can't be helped now... so let's not sit here chastise anyone... just consider it a lesson learned.
There are a few options available to resolve it... Since SandmanGTP was going to try rooting... I think staying the course is the proper direction and it's probably shorter than using RDSlite to recover with....
SandmanGTP... we know you had an issue with whatever rom you selected.. we don't know if you just had a bad flash and the rom would normally work fine on your phone or if there is some issue with that one rom and your phone... so it would probably make sense to at least try to use a different rom if possible.
I'm going to try to be wordy with my steps so you don't miss something and to help explain some of the logic I'm trying to use here... so don't get overwhelmed thinking it is as long of a process as it may appear.
Since you don't remember which one you selected specifically... I'd suggest picking two seperate roms for download this time. Select from some known stable roms... CM6 Stable (CM) has been released, Chevy's#1 SS 4.7 ( SS ) is another pretty good one, Bugless Beast 0.4 (BB) is another favorite among users and I've had good success with LithiumMod (LM) also...
So go into the Droid-Roms section here
Droid - ROMs - Android Forums and look each of them over... select a couple that you like the appearances of and then download them and save them to your SD card. You can either connect your phone when in Recovery to save the files or place your card into the reader you have... whichever you wish.
Remember to write down the names of the files that you save... When your card is in your phone... reboot into Recovery as already mentioned... select "wipe data/factory reset"... select "install .zip from sdcard" and then highlight one of the roms you downloaded to it earlier and let it flash it.
On restart... first you will see the Motorola symbol... then the droid animation that the rom has... please note that the droid animation will take longer than normal on the first boot... so be patient with it.
If everything goes well this time.. you should be presented with the first use script... so enter your gmail account info and just follow the prompts until it reregisters the phone.
Depending on if you had your settings "save" your account info and on how many apps you may have had installed... the phone may start redownloading your apps. This can take quite a while depending on the number of apps you may have had... Obviously if you didn't have it set to save your account info.. then you would have to manually redownload all apps you may have installed previously. I'd suggest to start with RomManager again, re-apply the CMRecovery and then perform a backup...
Assuming that things don't go well, for whatever reason and you have the boot loop again... If you followed my suggestion to get two different roms this time... just reboot into recovery again and repeat the same process but this time select the alternate rom you had downloaded...
The important part here is that you aren't "stuck" with just using whatever rom works during all of the above.. you are just trying to get your phone back to working condition again. After it's working again, you have backed up... then you can go "wild" some and try as many rom's as you wish... I know it took several times for me to finally find one that I liked how it worked and how it looked...
BEWARE... flashing roms is very addictive once you start LOL
