So, as part of rooting my Nvidia Shield Tablet K1, I wanted to set some things up before running the initial setup, things like configuring the adoptive storage, that seemed to make sense before downloading all my old apps. I was able to skip the setup and do what I needed but then couldn't find a way to run the setup after the fact. Can I force the device to run the setup again?
Hmm. The linked question isn't quite the same question, but the question itself gives the answer to your question.– Dan HulmeJun 2, 2016 at 8:33
Some Googling later, I found that you can send this command to your device:
adb shell am start -a android.intent.action.MAIN -n com.google.android.setupwizard/.SetupWizardTestActivity
and it will rerun the setup. In my particular case it came up with an error several times to the point I was a bit panicked and decided to try rebooting. Once I rebooted, the error came up again but I clicked through it and then it said "Just a sec" for quite a while but eventually got on with the normal setup.
