I've seen a few guides on how to unlock the Galaxy Nexus to prepare it for rooting, and they say that the fastboot oem unlock
command will "wipe your personal data".
I'm a little unclear on what gets wiped during this step. Is it just the /sdcard
area? is it everything but /system
? Something in between?
I know that adb backup
can (at least theoretically) back up everything except /system
while unrooted (see a recent question of mine). But I wonder if I would need to do an adb restore
of everything after the unlock step in order to keep all of my data and settings.
