How long should I expect a factory reset to take? I accepted all the warnings, my phone turned off and turned on again. It's been stuck showing "Google" for the last 15 minutes. I really don't want to take the battery out during a factory reset, so I thought I'd ask to see how long people have found it takes. I had a quick search and found someone said about 10 minutes. Edit: I haven't unlocked the bootloader.
