I am little confused by the behavior of my device recently. I tried to push a file into my unrooted device and it did throw "Permission denied on me". i did adb root and then tried to push the file and it seemed to be working fine.

Now, when I rebooted the device, I thought that until and unless I do adb root again, I will be seeing permission denied error. But somehow, but my push command was successful this time.

  • Does it mean that root command survives the reboots?
  • If yes, how can I take it back to the state when it was not allowing me to push the files.

I am doing this becuase I am trying to understand the behavior of a device without root access when I automate some commands and unpredictable behavior of my device actually has confused me at this point.

  • To which location in the device you tried to push ?

No, ADB root does not survive reboots (thankfully, that would be a nice security hole...) In your case, I'd guess that the permissions on that file got changed, allowing you to push it the second time.
