The RG405V runs Android 12 on the Unisoc T618 and does not have a reliable in-system OTA updater; Anbernic distributes firmware as a downloadable package you flash from a PC over USB-C using the maker's bundled tool and instructions. Because flashing can wipe the device, back up saves and your microSD first. Only use the image that matches your exact model. This is a DRAFT for human review.

FAQ

Is there an over-the-air update on the RG405V?
No reliable built-in OTA. You download the official package from anbernic.com and flash it from a PC over USB-C with Anbernic's tool.
Will flashing erase my games?
It can wipe internal storage, so back up saves first. Files on a removable microSD are usually untouched, but back them up too.
