 ## How to return back to the official firmware
 After iBasso released OTA-like update (1.05.036 or later), it is enough to re-apply any official firmare update, then do a factory reset.
 
+## How to update the official firmware
+You need to download the update from [iBasso site](http://ibasso.com/down.php), put it to SD-card or Internal storage, and start manual upgrade. Then you may install an add-on compatible with the new firmware version, if any.
