If you look inside the fastboot.sh file, there's this bit of code here:
command_array=($1 $2 $3 $4 $5)
for command in ${command_array[*]}; do
case $command in
8917)
down_platform="8917"
continue
;;
8937)
down_platform="8937"
continue
;;
esac
That means you're supposed to pass an argument to the script with the model? number of the device. So since your device is an 8937, run the script like so: ./fastboot.sh 8937
Further down the script, you can see what it actually does: it unlocks the device, flashes a bunch of partitions and finally reboots it. Since you didn't specify the model number, it skipped the flashing bit and went directly to the reboot bit. :)
Edit: I also took a look at the .bat files, they basically do they same thing except under Windows, and it's specific to the model.
