Hey
(This was my test phone, where I just try out custom ROMs)

I was recently SBF'ing my droid to 2.3.3 and I wanted to update to 2.3.4 so I did an OTA Update, and used voodoo rootkeeper, well, in that process, I went to install CyanogenMod because the 2.3.4 update was kinda pointless and I wanted to change it

As I was flashing CM7 the installation claimed to be successful, after that, I was stuck in a boot animation brick (Just the motorola M sign), so I did a factory wipe, still nothing

So then I decided to SBF back to 2.3.3

And there is where the problem occured, SBF flashes now fail, because it says "Unable to send JUMP Command"

Any Suggestions/Help, or is this phone a paperweight?

You cannot go back to 2.3.3

use the Droid2_621_SBF-and-RootCD.iso

It worked, Thank you so much
