I have a Samsung Galaxy S2 and a PC running Debian 8. How can I turn on USB debugging using command-line on my PC without touching the phone?

  • This question is for the Galaxy S3 but is very similar but unfortunately does require root : android.stackexchange.com/questions/120394/… – LJD200 Jan 28 '16 at 21:35

    If I may ask, what are you aiming to achieve by doing this? There may be a better way to do it. – LJD200 Jan 28 '16 at 21:37
  • USB Debugging is activated on the device... You cannot do this "remotely" since without USB Debugging, you can't execute the proper commands to enable/disable it, or give your computer authorization to use USB Debugging. You must be able to physically use the device to enable this feature. – acejavelin Jan 29 '16 at 5:48
  • @acejavelin: you can enable USB debugging using an SSH server. If the Android is rooted, run an SSH server, get remote shell access on PC and make changes. – Firelord Jan 29 '16 at 11:34
  • @Firelord True... The user made no mention of root or being non-stock, guess I shouldn't have assumed. This would still require interaction with the phone though to enable SSH. – acejavelin Jan 29 '16 at 12:20

If the question is simply "using the command-line"

Let it be simple (root possibly[1] required):

settings put global development_settings_enabled 1
settings put global adb_enabled 1

And then you need to

echo "mtp,adb" > /data/property/persist.sys.usb.config

If you want to do this without touching your phone

Then I'm feeling interesting because you won't gain access to command line via PC before enabling ADB, so it's impossible to enable this prior to touching your phone.

1. Actually you only need either 'system' or 'shell' privilege, but 'system' is impossible to access without rooting and 'shell' is granted only if you're already logging in via adb, where it makes no sense to enable adb while it's already active.

  • Hm, and that works "using command-line on my PC without touching the phone?" – Izzy Jun 2 '17 at 12:32
  • @Izzy See edit. – iBug Jun 2 '17 at 13:41
  • Yupp. Exactly those were my thoughts :) So taking the question literally, the only valid answer would be: "Not at all." – Izzy Jun 2 '17 at 13:43
  • @Izzy Let's say, assume only the title is taken, this is actually a valid answer because it involves no GUI. Grab a terminal emulator and you'll find it right :) – iBug Jun 2 '17 at 13:47

    @Izzy I had temporarily enabled adb somehow, and needed it to be permanent. – Nonny Moose Jun 1 '18 at 0:33
