Finally!
I followed MookieDogs's instructions and was able to recover my Omega2+.
In short:

1. solder RX0 and TX0 on PowerDock to extend Omega2+ serial0 (console serial) RX and TX lines
2. cross connect RX0 and TX0 line with respective TX and RX on 3.3v level serial port. I used Raspberry PI serial and minicom.
3. on Raspberry PI (or another Omega) use serial port with "minicom -b 115200 -D /dev/ttyAMA0" command
4. now you are able to connect to Omega2+ console and configured it as you wish. I did manual factory reset using info on https://docs.onion.io/omega2-docs/factory-reset.html

All thanks go to MookieDog.

@Luciano-S.
Thx for reminder there is SD card slot. Will investigate available options.

@WereCatf
This was my last resort after previous unsuccessful attempts. But I did not use 3.3v level serial port but serial port via USB adapter. Connecting was done by pairing my port RX with Omega2+ TX and vice versa.

@fossette Thx for info. I somehow missed this topic. Now I know that Omega2+ Ethernet is not IEEE 802.3 compliant without additional hw.

I'm a new owner of Omega2+ with Power Dock.
There was no problem in connecting to Omega2+ while it was serving as AP. The next step was to try and connect Omega2+ to home AP but that effort was without any success (and that is for another topic). After few days of fiddling with every available wifi option I managed Omega2+ to become unreachable via wifi. Omega2+ shows all LED activity as before: green LEDs on power input, blue LED on PowerDock and orange LED on Omega2+.
Presuming that after wifi restart and while applying new settings I somehow shut down the radio, I started recovery procedure:

1. factory reset - 10s holding RST button on PowerDock = nothing happens
2. having no expansion modules I connected Ethernet cable with its RX's and TX's directly to expansion header corresponding pins on PowerDock = no ethernet connectivity
3. tried the same with serial pins connecting it serial port = no serial connectivity

I believe that Omega2+ is OK, but I'm not so sure that is the case with PowerDock (unsuccessful factory reset was the first alarm). How can I find out which one is broken or to recover an Omega2+?

One option is to buy another dock and Ethernet expansion and try to connect to Omega2+? The second option is to acquire 3.3v power source and connect Omega2+ to it and try to factory reset the Omega2+? Or to connect Ethernet signals via Ethernet cable to a switch?
Are there any options that enables me to test device without acquiring more new devices?

Any help is appreciated.
