Default [Q] Rooting Motorola Defy+

I have been trying to root my Motorola Defy+. I have tried using SuperOneClick, z4root and Framaroot. None of these appeared to work, in that I got no messages to say they had been successful. However, the device now seems to be rooted. I have installed Busybox and ROM Manager (Superuser is installed but doesn't work as it reports the su binary is out of date but can't update) and when opening these there is a message to say they have been granted superuser permission. I also have ClockworkMod installed and apparently working.

However, if I try to backup or install a custom ROM from ROM Manager the device boots into recovery mode then hangs (boot looping??). I can only get out of this by removing and replacing the battery then rebooting back to the standard ROM.

Can anyone help, or explain what may be happening, please.
