but even 1.9beta its not the same from 2019-03-14 (the one before I upgraded)
now I got 2019-12-03. have eco and hifi functions also battery is better not running out so fast like before.
Ha! This is what I though, too! When I upgraded mine, I thought exactly like you - that it did not work. So I wrote to Hifiman and asked.
But they told me the numbers behind the 1.9 (2019-03-14, 2019-12-03 etc. ) do not matter at all! As long you have 1.9 and it has eco mode now it WAS upgraded! So it actually worked!
PS. Many things surrounding this player are really weird and, as the name says, "beta". The only thing one can do is focussing on enjoying the sound.
