Forgive my newness... I've installed Android Studio/Android SDK in Windows 7, enabled debugging on my Droid Turbo 2 with Android 7.0, system version 25.216.2.kinzie_verizon.verizon.en.US, and successfully attached my device. I've successfully made a backup (haven't tried restoring it), but of course it's a compressed file. So now I want to browse my phone's directory structure. So I opened a shell and tried to navigate around with ls and cd, but I see a lot of directories are giving me Permission denied.
Is there anything I can do about this?
Edited to add: I was particularly interested in having a non-cloud method of backing up my contacts, sms history, and call history. Normally, I periodically connect the phone to my PC via USB and just copy everything in Windows Explorer. But, as I discovered when I moved to another phone yesterday that already had some of my contacts on it, the contacts file is not accessible to this method of backing up. Verizon made a hodgpodge out of old and new contacts information which is going to take me another hour or two to sort through. It would have been easier if I could have just restored this file.
I'd rather not root my phone if I don't have to, and from everything I've read, there is no root discovered for the Droid Turbo 2 anyway.
