RK2020 red light of dead

[beeno92]

I bought the RK2020 on aliexpress but it was broken when receiving the goods, turned on and there were two red lights on the back, not display, when I charged for 2 3 hours, I turned it on, it showed the word hardkenel (flash with odroid 3.7 emuelec ), run for 10-30 seconds and it freezes. If it turns on at that moment, it blacks the screen and two red lights, but wait an hour later it turns on and it freezes again, loops. When it freezes, it has more blue light to freeze, if normal, the green light will blink, I tear down it and take out the battery but still problem, what is the problem, please help me, everyone, thank you very much.

Have you tried reinstalling the firmware on the RK2020? We don't have the firmware available, but the seller you got it from might.
The process for reinstalling should be the same as pretty much any other device. Take out the card, flash it with the right firmware using something like Balena Etcher or Win32DiskImager, then put it back in the system.
If that doesn't fix it, it could be any number of hardware issues (battery, mainboard, etc.).
