So it looks like the non-persistent root steps should work for the NSZ-GS7 correct? I get through everything up through step 7, and instead of "#", I get:
"Entering character mode
Escape character is '^]'."
and it seems I do not have root access - I am unable to push Superuser.apk to /system/app (failed to copy ... Read-only file system).
I was able to push Superuser to the tmp folder and install it from there, but it doesn't do much good without root access or the binary...
Any advice? Forgive my ignorance - adb is very new to me...
