FOR DROID 1 ONLY!
I have seen a lot of issues and answered a ton a questions about easy root and Rom Manager. I'm not here to bash any apps, it just seems like lots of people are having issues with these.
Don't get me wrong, more times then not it is user error, which brings me to...
#1 if you want to root do a little homework: What you need to know about rooting:
#2 After reading, the least problematic way to go is here: SBF to root and to unroot
Do option 1, then 2, then 3. Then you can install a Custom Rom to gain root access. Their are Roms that are rooted that are "Virgin" (just like the OTA but rooted) or ones with all the "bells and whistles"
This is easily the "safest" way to root. And in my opinion VERY EASY!
