Moto G3 (6.0) - Can't access files, tried many guides I'm unable to access files on an Moto G3 updated for Marshmallow 6.0 ("this folder is empty" when connected to a pc, tried on several computers). I tried several fixes and guides but nothing out there seems to work.

Swiped down after connecting to pc, there are no notifications nor options to choose from.


SD card not showing files when connected to pc


Been there, did that. Rebooted, waited... once again, no files &amp; no notification to change USB connection mode. I did the wipe cache partition part too and waited for some good 10 minutes after doing it before connecting USB


I wanted to try more options via USB debugging &amp; such, but I cannot enable that either. I tap a bunch of times on top of the "build number" option in the menu and nothing at all happens: http://wccftech.com/enable-developer-options-in-android-6-marshmallow/ 
I went on to search how to root the device which seems to require USB debug mode which I could not enable on 3. 


I'm not sure if I'm missing something obvious here but none of the answers/guides I tried so far seem to work. Anyone knows what's going on?
The Moto G 2015 has known issues with this, and there is a fix most of the time...

Disconnect the USB cable
Navigate to Settings - Apps
Press the Overflow Menu (3 dots in upper right), and select Show system
Find External Storage and Media Storage
Open each item and select Storage
In this screen for each app, press Clear Data
Reboot
After the system appears up and working, wait a minimum of 5 minutes after the phone is fully booted. Databases are being rebuilt for these applications, if you have large SD card with lots of media files (several thousand or more) this may take longer to complete but there is no way to monitor it and know when it's done.
Reconnect the USB cable
Pull down the Notification Panel
Select USB Connection and change it to MTP. Note there may NOT be an icon in the status bar.

MTP connections use the External Storage app, and by association the Media Storage app, for USB access to the device. There is no direct access or &quot;mass storage mode&quot; anymore, it is all software emulated.
If this fails, a full factory reset is usually required. In rare instances, this does not fix it most models have firmware available on XDA, but that step likely is beyond the scope of this question.
Of course, all this depends on a working USB port on the phone and a good cable... although it is extremely unlikely, it is possible for the USB port in the phone to be defective.
