I was messing around with my nrf52832DK and set it to boot mode now the LED5 is flashing continuously, I've tried uploading JLINK firmware into the boot device folder but it comes up as a removeable disk, which I am unable to open., and after 10 seconds the removable disk disappears, I've read the forum and I've tried power cycling, changing the cables. I'm unsure of what to do next. also when the DK is not in boot mode the LED4 pulse every so often
