Thank you for continuing to support chromebox fans.
I've bought one more Zako recently and installed your recent firmware at once.
The firmware is dated 01/04/2019.

My question is: Is it possible to downgrade the firmware to the one dated 08/27/2018?

The problem is that the Zako shuts down when trying to sleep. I'd even say it performs an unsafe shutdown when I try to wake it from S3 with a mouse, a keyboard or pressing the front button.
It happens under Libreelec and under Windows 10.
I have another Zako here with 08/27/2018 firmware and it runs just excellent.

Thank you in advance.

But I can hardly imagine what kind of issue it should be to make the S3 mode broken and not to touch anything else...

I will be grateful for any advice.

Thanks, I'll test it carefully. The idea deservs consideration.
But I don't believe it is faulty because it withstood  the complete Windows 10 installation, Office 2019 installation and full update procedure without any problem.

There's a good method to check if this is a firmware problem: I can update my second Zako to the latest UEFI firmware and see what happens.
The problem is that I badly need S3 mode on the second machine and don't want to take this risk.

Well, seems it's time to look where is my old good SPI programmer....

Looking for something to run LibreELEC on--don't really care about ChromeOS or dual booting. Also, I want to do an upgrade over my Amlogic s802 (2 GB RAM) box. Is development for this model of Chromebox still underway? Can I expect this hardware to perform as well as or better than my Amlogic box? Can I expect upgrades of Kodi/LibreELEC to run on this box for a bit longer? Thanks

Really need some sort of upgrade path since it looks like older Amlogic stuff like what I have is barely even supported anymore (have not managed to find any LibreELEC release for it so far). Hope I'll be able to score this one.
