  1. Yes, I really didn't read this thread. I tried, but... I was so frustrating of my two days struggle so just closed eyes and breathlessly waited for a miracle. But realty hurts me one more time. Now i'm reading thoroughly the thread and other materials. Thanks for all.
  2. Hi all! I've bought two OPi Zero 2 from Ali. Taken for them SanDisk Extreme A1 microSD cards. Used recommended here SD Memory card Formatter, formated cards, and used balenaEtcher to burn ISO on the card. ISO were taken from https://www.armbian.com/orange-pi-zero-2/#kernels-archive-all. After burning, checking process shown that all is correct. For power sully I tried typical phone charger with 5V/2A output, another phone charger with 5V/3A output and finally dedicated power supply with 5V/5A output. SBCs were connected to monitor by microHDMI cable that was preliminarily tested. Both SBCs show nothing, totally, nor LED flash, nor any data on monitor, nothing. While connected to each of used power supplies I checked the voltage on 2 and 6 pins, it was 4.8V, 4.9V and 5.9V respectively. Now I'm at dead end with all my efforts, don't know what to do more. Thanks for reading this strengthless moaning.
