@Luciano-S. Yes, the LED is off. But unfortunately the current consumption is ~65-70 mA (at least on my O2+). Maybe the MT7688 freezes and the state of the RAM, FLASH, etc. is not determined. Additional similar states of Omega2+: This is my pet Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: 8701d944 Rebooting in 3 seconds.. Hardware Reset - when the RST pin goes to LOW (eg. via a momentary push button to the GND). Update Chris Stratton taught me to understand, my problems are related to Omega2+ only. Please forget it if you are talking about Omega or Omega2.
