In order to install the firmware you need RK Batch Tool in your PC included in the rar package.
Open Batch tool and select the Legacy_XX image file (.img).
With GPD power off, just connect it via USB Cable to PC. Wait until battery charging animation dissappears. Then just press and Hold Volume + button and Press Power. RK Batch Tool will detect device, and you’ll see the number 1 with a green box. If you see with a pink box, just select Switch Button until you see it in green. If the system ask you for some drivers, then just use the one included in the Batch Tool (or using driverInstaller package to install rockchip USB drivers).
Once device is detected with a green BOX, just select Restore and wait patiently while firmware is written.
Device will auto reboot to recovery and format your partitions. Just wait patiently until all process is done, since it’s a long process and first boot can take several minutes, so just wait until it finishes and you see the home Android launcher.
