Here is the first custom firmware for xDuoo X20 based on stock V1.1: Link

- English and Russian language strings and GUI offsets was corrected;
- Highly optimized graphics, fonts and binaries for maximum speed;
- Other minor bigfixes;

Enjoy.
P.S. If You like my work you can donate on the site from my sig. It is much appreciated.

Cool... Never know DAP has custom firmware as well. Well done.

 

[voloner]

Yeah, just knew you can customize the DAP firmware. How did you do it anyway? where did you get the source code and stuff?

Just to let you know, your custom firmware breaks UTF-8 Japanese characters. I rolled back to the official 1.1 release.

Looks like an X10+ to be honest

And they promise to never provide firmware updates to fix known problems like the playback speed of the X3 for purchasers of their new product too? Seeing as how they've already stopped updating the Nano D3 firmware while it still has obvious bugs.

Most likely

My review on the Xduoo X20! Enjoy reading!

[edit, somehow my quote of Jaxz, post #105 photo of X20 / M3S did not take]

I was going through all following pages in this thread in hopes of finding a more comprehensive compare between those 2 players (X20 vs M3S) ... I am really undecided and currently leaning towards M3S, for semi silly reasons like looks, better screen (?), slightly slimmer ...

Did I miss a link to a showdown review?

 

[handwander]

Any news on that X3+? Might just wait for a price drop on the X20. Wish more manufacturers were making similarly sized players.

 

[shahkhan]

Any iidea how xduoo X3mi sounds?

Massdrop says it has dual card slots. Is that something new? I thought it only had 1?
