Unable to update Volumio on Tinkerboard

Hi, I have been experiencing a problem as for the past few months with myVolumio. I am running myVolumio on an ASUS TinkerBoard coupled with the Khardas ToneBoard DAC. I am currently running myVolumio v.2.527 as I have not been able to upgrade to what is now v.2.649. Initially, whenever I would try to upgrade, the SBC would simply freeze up and crash. Now with newer releases, I am able to upgrade to the current version but you notice incongruity on the GUI and finally, all by itself, the OS reverts back to the previous version it was on.

Question is, has someone encountered the same issue and were able to find a fix or work around? If so could you please point me in the right direction as to what one must do to get it to work. Your help in this matter is greatly appreciated.
