Welcome to Android Forums.
I moved this thread to the sub-forum where root-related questions about this phone are discussed.
Since the Droid is a pretty old phone I wonder if that is what you are using ... perhaps ...
Droid x
Droid X2
Droid Bionic
Droid Razr
Droid Razr Maxx
Droid Razr HD
Droid Razr Maxx HD
Droid Mini
Droid Ultra
Droid Maxx
... they all have forums and all things root sub-forums.
If you have one of these send me a Private Mail and I will move this thread to the correct area.

Moved from the Motorola Droid section. Based upon the poster's other posts, I'm going to bet it is the one I bolded in my quote of your post.
Now for the OP. I used to read about your phone a bit, and if it is rooted, then you should be able to install a custom ROM (if you can still find one) via either safestrap or bootstrap. I cannot remember, but one or both of them will allow you to 'install' CWRecovery, to make a nandroid, then install unsigned 'update.zip' files; the key thing is unsigned, meaning a custom ROM. Or you can install one without a custom recovery, however the next paragraph still applies.
The real bummer is that the bootloader was never unlocked (IIRC) for your device, therefore, any 'custom' recovery installed doesn't work like otehr devices with unlockable bootloaders, i.e. if somehow something goes wrong with a custom rom install and your /system gets corrupted, you could/would be screwed as the 'custom' recovery is installed to /system and not it's own partition; one to which you can boot to separate from booting into Android leaving you with a non working device and possibly a brick.
If that happens, your only recourse would be if you can reflash a .sbf file with RSD Lite and start all over again, unrooted.
You have some searching about to do. good luck
