Glad to hear it.
You can also backup/restore from recovery. You just have to switch the USB connection to UMS (a/k/a "mass_storage").
Code:
# usbcfg 18d1 4ee0 ums,adb
There's no guarantee that the ADB can be reconnected, it depends on your drivers. The entire 32 GB of the EMMC will be presented over USB like a flash drive.
