# Before running the script:
#
# * lunch with eng variant. For example:
#   lunch flame-eng
# * Build the full system image and flash your device
#   m; vendor/google/tools/flashall
# * Remount the device to allow system rw.
#   adb remount; adb reboot
# * Connect the device to host machine to allow atest to build properly

# Note: This script assumes the device runs with NEW_INSTALL_ONLY strategy.
# The script will have to be updated when switching to BEST_EFFORT strategy.
