ok, you have D2 BOOTSTRAPPER (not bootloader) open that up, tap bootstrap recovery, grant super user permission, hit OK, then tap reboot recovery. this will boot up into clockwork mod recovery (black screen with green wording) use the up/down volume to go down to backup/restore, hit the camera button.
go to backup, then go to yes. and it will work its magic and make a full system backup (basically a snapshot of your phone so when you restore it, everything will go back the way it was when that "snapshot" was taken)
then you should be good to go. but like i said, i had bootloops when i restored a GB backup...not sure if it was a fluke or what, but it didn't work the 1 time i did it.
