Using adb pull without rooting Nexus7 (2012)

[matt]

I use es file explorer. In the left side expand tools and turn root explorer on. With the app root explorer there's a mount rw button for read/write operation, default is ro read only.

Thanks, that works.  I can read the wifi passwords file that I wanted, but it does not have the info from before rooting. So I am trying to restore from Google backup again.   I removed my Google account and then, on the new setup of the same account, the only check-choice I have is "BACKUP AND RESTORE.....[] Back up data to your Google account"    I have not checked that because of your advice....  and I don't  get any restore option.
  Now what?  I am thinking of checking the box because I  am assuming I can't be worse off than I am now (which is, no access to my previous WiFi passwords file).  What do you suggest?

If you're rooted, download a terminal emulator and read up on using adb bmgr. One of the commands will show the backups on google server tied to the device ids. Then using an I'd you can force it to backup to your device.

You shouldn't need shell in a terminal. Just su. Then bmgr list sets. Then  bmgr restore set name. Then maybe bmgr run.

It may be that the backup wasn't completed on the server,  delayed or something, sorry. I'm not seeing several of my devices for some reason.

Thanks.  I used "bmgr list sets" and find two sets, one for each of my Nexus7s.  I cannot tell which is which, because the hex number is not the serial number or MAC address or anything I can find.

Now I'll look up the subcommands for bmgr ....

Well, well!  I used "bmgr restore" for the first-named Nexus7 and Google restored all my apps and WiFi networks.  My project is finished!   Thanks for your help, Matt...  this solution to my "adb pull" question certainly is not well documented.

Flying by the seat of my pants on this one, lol. Great!

I am posting the answer to my question, as the thread is lengthy.

1. I wanted to get wifi passwords off my old Nexus7 (not rooted) to use on my new 2nd gen LTE
2. All the apps that would show wifi passwords needed root
3. But I was told if I installed the program adb on my Windows computer I could pull the file /data/misc/wifi/wpa_supplicant.conf, which contains the wifi passwords, even without rooting
4. This advice is NOT TRUE --you need root to pull this file to your computer using adb
5.I rooted my old Nexus7. But on startup it did not offer a choice of restoring from Google's servers
6. I installed a terminal emulator and ran bmgr restore
Google downloaded my wifi passwords and all apps to my Nexus7
7. Since the Nexus 7 is now rooted, there are various ways I can see the passwords.
