SOS+1 (hard fault) and intensive heat

i have a problem with device. It blinks SOS + 1 and it get really hot.
Steps i did:

  1. particle update (in DFU mode), doesn’t work
  2. particle device doctor: doesn’t work in the end, i went through all the steps
  3. tried powering it on 3.3V and 5V from other photon
  4. i can’t enter safe mode nor setup mode.
