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?
