Linux install script for One Touch Fire isn't send the correct commands

[shigutso]

the Linux install script is very buggy, but mostly is that it doesn't even try to flash system.img because of a typo

line 155 reads:
./fastboot flash update/system system.img

should be:
./fastboot flash system update/system.img
