# Updated: Arcain

# Added:
#   * custom PIN range
#   * auto-restart option after x amounts of tests
#     (S7 Edge gets stuck after ~12000 tests)
#     user -r param to enable this option, followed
#     by a number to customize (ie. -r 5000 to restart 
#     after 5000)
#   * some sort of test for hooking-vold running
