This is a common guide for reflashing RockChip based devices. All RK SoC (RK3066, RK3188, RK3288, RK3229, RK3328, RK3399 and so on) supports the same applications and drivers for Host system, if 3rd party producers do not add any other limitations or special options. Differences can be in hardware parts, so you need to detect OTG port and recovery buttons correctly.
Notice: this guide is 100% working with Ugoos RK devices.
