Well since you don't have root, all system content is only readable. So using a file explorer (Es File Explorer - recommended) go to /system and scroll down. When scrolling down you will see build.prop tap it and open it, you won't be able to save or edit it. So click edit (click top right menu button) in the built in note pad, copy all of the content. Make a .txt file and paste it there. All the info should be there about the device.
