i tried to debug my device (without a particle hardware debugger) and therefore got an error (thought thats done with the regular usb connected cable not with another hardware piece).  
then the device started to blink purple so i thought i just put it in DFU mode, flash tinker and done.  
unfortunately, its in dfu mode now and when i flash tinker it says: flash succcess!  
but seems like thats not true because the device just stays in dfu mode

i could reset it now but i would really like to get somehow out of that without resetting again the argon  
is this a known problem/behaviour of the device?

Try running a full update via `particle update -v` (possibly) followed by `particle flash --usb tinker -v`

Yes, when the device is ill-treated it tends to sulk till you apologize 😉
