Had a working Android 7.1.2 eMMC. Not sure what I did to it but now it boots to the Recovery Menu but there's no keyboard or mouse response. Can't move to any selection in the menu. Reload the eMMC? Boot to an SD Card linux image and fix it from there somehow? Thanks for any tips.
I'm having this problem too. I'm assuming the GPIO can be used to navigate, but I'm not sure which pins, if any, would work, and I'm not prepared to fry my board. I'm gonna try a reflash if I can't find a solution soon.
maybe use adb while having the male to male usb connected to the rock64 and computer
Did you figure out which GPIOs?
