This is a magnificent DAC. Well done! I have the F.1a firmware. Any reason to upgrade (Windows 11 / USB)? I have no issues so far. Where is the official site to download firmware upgrades when they are final? Thank you!

As far as I know there are only two firmware versions - yours and F20 which is available for download in the first post of this thread.

I just emailed someone through the Gustard website. The first response said it wasn't possible to update the firmware and the second email said there are no firmware updates. This is odd at best......

Did you provided the FW link from here ?

So they can see you aren't kidding (or mistake) ?

His last post here was from Oct 2021 !

What hopes can you have from?

He won't access since Apr 27, 2022 (probably left?).

Is a real pitty, as I'm still interested on X18, but w/o any support, no thanks.

If you are lucky, your unit didn't entered into a "stuck" state. Otherwise only with JTAG to unblock the access and flash the correct firmware.

You'll need to contact them directly: [email protected]

The other way (harder) would be by desoldering the Flash EEPROM, reprogramming on a PC with a flash programmer, and resoldering again (need tools, skills, binary files, etc).

Good luck.

PS: I did plently recovering stuff by using JTAG myself (SFP fiber module, FTTH equipment, WiFi router, etc).
