S905-H version? (Xtreamer Whizz)

I just cannot figure out if Whizz can be upgraded to 9.3. Trying to update by placing the update file in the update folder, I get an error on incompatibility with 3.14 kernel.

There is of course this post

saying that there are two builds to choose from when downloading but I just can find the link for the original Amlogic build.

Is there a solution or should I stick to 9.2.8 as the last upgrade?
