Dear eGreat support team. Could you please eventually solve the problem with insufficient file system permissions for built-in Transmission application. All Transmission system folders are read only! Therefore the Transmission application is not able to change and save its own settings (settings.json). As a result you can not apply changes for download location (it remains folder on SDCard) and change it for example to external HDD. This is well known problem and it really makes this very good device (from technical point of view) into a mediocre media player with limited usage.
