Powkiddy A20 Custom Firmware -

Once you have CFW installed, you aren't done. You need to overclock the GPU slightly to handle the thermal headroom the new firmware provides.

The most active development right now is happening on the EmuELEC fork for the A311D chipset. The specific build you want is labeled EmuELEC-Amlogic-a311d.a20-4.6. Here is what this firmware offers specifically for the A20:
