I installed the x735 shutdown script on my pi with the x735 board. The script allows the hat to provide power, and then safely shutdown on button press. I upgraded the board to a x728 which allows batteries, and when i start it up, the x735 script automatically runs and shuts the pi down. Normally one could just go into the SD card and remove the file, but I am unable to do that due to the filesystem type (berryboot). What all this means is that I need a way to halt the startup scripts without editing SD card, either through key combination or something else. Here is Link to bad script.
Thanks and I know this might not be possible!
