[Q] Help using ADB pull

Hi,

I'm currently trying to use adb to pull some data from my phone but i always get "error: closed". Im running it from cmd.

When I use the command "adb devices" to see if my phone is connected, I get something different from the others is i am getting

List of devices attached
XXXXXX sideload

instead of what most other people got
List of devices attached
XXXXXX device

Is this a problem? What am i missing? Thanks a lot for ur time in reading this
