The MangoES v2 has 3.10.82+, which according to the above post is 1.0, which says that it would have to be re-imaged? I'm not quite sure how to accomplish this or even if I want to pursue this.
As the name suggests, it appears you'd be overwriting what you have with a complete image. I have seen the command
sudo make_modules install To install and use the linux kernel.
But I'm not confident that will work given the architecture of the mango unit. I could suggest grub bootloader to select the linux kernel but even then I think you'd just be fiddling as the system itself is a complete image. that is booted and run
Sorry I've exhausted all of my options. I think contact support directly will give you a better outcome now.
It should be plug and play. Check both ends of the connection, and the adapter. A few possible points of failure there. You may also want to have a USB keyboard to refresh the display if it's gone to sleep, and you may want to restart with the cable plugged in (but I suspect you may have tried to boot it a few times, although iirc some V2 units had a power issue with the HDMI being plugged in and a power cycle through unplugging / replugging power, so I would say try also plugging it in shortly after plugging in the power. You could see that issue with some LEDs on the board still illuminating from the HDMI plug when the power is out).
@mihairosu Just disable it in sources.list on your hardware. Phil has said they wont be servicing from this repo anymore.

Power supply is probably the wrong word, it's 48/24v dcdc converter. Once the unit is up and running the unit only draws <1Amp and everything works fine. Even If I put it on a small 9Ahr battery it will drop the voltage during startup 1-2Volts on the battery.
I've tried a 300W converter of the same brand and next i'll try a different brand.
Is there a different onboard psu for the AC model vs. dc model or is it the same unit with a different plug?
