To downgrade to Stock rom it is very simple:
1.Download RSD lite and Motorola usb drivers to flash SBF file.
2.Download Stock froyo SBF for your region from here. Check to compare your version no.
3.Check USB debugging on your phone and connect to the pc and wait until all motorola drivers install.
4.Open RSD lite(right click and open as a administrator). It will show connected. Now select the sbf file you located on the system and click start and wait till it completes 100% process. thats it. it will flash your phone to stock froyo and it will automatically restart and boot.
Note: Some times when rebooting after RSD lite flash your phone stuck in bootloop(M logo or it continously loading in Android menu). It is better to go to stock recovery(Hold the vol - button and then power button and then release it. you will get android logo with exclamatory symbol. Press vol - and vol + button at the same time to get in to stock recovery). Select wipe data/factory and wipe cache.
