Need one-line adb shell su push & pull to access /data from Windows batch file

I wrote a Windows batch file that replaces Amazon lockscreen ads with user images on _rooted_ kindle fire hd 7", 2013 (kfsowi). Just learned I botched the adb commands because I was running "adb insecure" so was getting su access without writing it into the adb commands. **What I need:** To run in batch file, I need one-line adb shell su commands to pull from/push to /data on this device. (Or I could use adb -d shell su -c "mount -o remount rw, /data on one line followed by the pull or push) I have fixed an ls command like this: - this worked with adb insecure: adb ls "/data/securedStorageLocation" - what I needed was: adb shell su -c "ls ./data/securedStorageLocation" Now I need same for pull and push. The problem: - With adb insecure, this works fine: adb pull "/data/securedStorageLocation" "C:/destination" - Without adb insecure I get: remote object '/data/securedStorageLocation/' does not exist Above happens even if I first run: adb -d shell su -c "mount -o remount rw, /data Can someone tell me how to do the pull and push with adb shell and su? EDIT: adb root command doesn't gain root on this device
