Restore Android to OPi rk3399. Does not load or output anything via HDMI

shrkn

Hey!

Recently I came with aliexpress fee. I connected it to the monitor via an HDMI to DB15(Vga) adapter. Connected via USB dongle wireless mouse and keyboard. Connected power via DC input (12V 3A power supply).
Android's loaded. I installed Antutu 7.1.0 (apk) for testing. Run the test. The test was performed for 5 minutes, then a dark background appeared on the monitor screen and nothing happened. I pressed the reset button.
However, after that the Android did not load. I unplugged the DC, plugged it back in, but nothing happened.

Next, I installed Driver Assistant 4.5, connected the OPi rk3399 USB-typeC cable, entered the MASKMODE and downloaded the firmware: OrangePi-rk3399_Android6.0_20180101.img all went well, but the Board still does not start. Tried to load also firmware: OrangePi-rk3399_Android_update_20180712.img result has not changed to monitor via HDMI as before nothing is loaded.

Please help how do I restore Android that was before?
Why is nothing output via HDMI? What am I doing wrong?
What am I doing wrong?

Thank you for help.
I solved it. More precisely figured out what was wrong. Maybe this will help someone. I just connected the HDMI output to the monitor via another adapter (HDMI-DVI) and it worked. Apparently something happened to my old HDMI-VGA adapter.
