Getting Model/Model Variant/Product Name/Bootloader Version/Android Release/Serial Number

All of this information can be gotten from an adb shell. From your machine with the tablet connected via USB.
Don't ask me why there are so many different identifiers, but here they are:

# Model
~ # getprop ro.product.model
SM-T800

# Model Variant
~ # getprop ro.product.device
chagallwifi

# Product Name
~ # getprop ro.product.name
chagallwifixx

# Bootloader version
~ # getprop ro.boot.bootloader
T800XXU1ANFB

# Android version/release
~ # getprop ro.build.version.release
6.0.1

# Serial number ( Not a real serial number below but this is the format ) 
~ # getprop ro.serialno
023418ad419c1751

And there's a lot more you can get just by running getprop

~ # getprop  | grep 'ro.boot\|ro.build\|ro.product'
