freeze when entering clockworkmod recovery

previously, i tried to install some theme in my D2g , but sadly it got failed and stucked in a boot loop.
then i used the nandroid backup to restore the "system" file only,
after that, my phone could successfully boot up as normal.

but now i got some strange issues,
first, i cannot reboot recovery, it just freeze in the white motorola icon.

second, i cannot add contact other that google account, i want to add facebook as the profile pic source, but failed.

third, the motorola widgets , like calender cannot add into the homepage, it just no response after press add widget. i am not using launcherpro , just as same as
the time before restore.

is that i must flash sbf, and this is 100% work?and bring my phone to normal?

If you flash an SBF, yes, your phone will go back to 100% normal. After you flash the SBF, you may bet a boot loop, but you should be able to pull the battery out, and put it back in and boot into recovery. Wipe the cache, and you should be good to go. You might also have to wipe the data, but that will lose all your data from your phone, so use it as a last resort.
