How to update transission in EX2 Ultra?

Hi All,

I have a WD EX 2 ultra NAS running on firmware ‘2.31.149’. It comes with Transmission app which has a very old version ‘1.06’. Is there any way to update transmission version to ‘2.92’ or ‘2.93’?

I tried to install it from App section 'Install an app manually" by browsing to bin file provided here “” but I always get error message “Failed to install app.”
