mmmmmm .... boot loops. There are watchdogs that run that look for things crashing that shouldn't and do the brute-force "correction" of rebooting. I'm not sure how you broke out of your boot loop but if you are doing experimental things then you can disable the watchdog with the flasher tool. My guess would be one of the wifi sniffer tools mucked with the wireless driver. I don't think the built-in driver is completely able to handle the modes that you need to be in to fully task advantage of those tools.
