I'm facing the same issue as i'm writing this and i think there are some steps missing, from their .pdf file. I'll tinker around some more and see if i can sort it out and if so, i'll post back here.

So in my case, it was a case of not paying proper attention to which file i should have selected. Are you sure you've selected the proper "SMSL_IAP_XX_XXX.hex" file and not the "MM32F103xx_o.hex" one? Because if you've selected the latter, you'll semi-brick the device. If so, go through the steps needed to put the DAC into firmware upgrade mode once again then when at the file selection screen, go up one page and select the proper .hex file. It should work as intended and the DAC will boot up once it's finished updating the firmware.
Hope this helped.

Are you using Windows 10 or 11? Do you get any windows error upon crashing? Have you checked "Control Panel\System and Security\Security and Maintenance\Problem Reports"? What about the Event Viewer? If you can find any error on the program, reply back here and i'll try to help you more. Additionally, have you tried running it out of another Windows machine? (laptop, another desktop, etc.).

Sorry for the late reply but i rarely come back here.

All these people succeeding to upgrade and brick their SMSL while I am sitting here trying to get the connection state working.

Well, actually you do not brick your device if you use the wrong update file. It just stays in the "DFU" (for the lack of a better word) mode and you can restart the update process, using the correct file. As i wrote in one of my earlier posts in this thread, i also thought i "bricked" it but it was just me not being careful while selecting the proper file.

What do you mean by the "connection state"? Getting it to boot into the update mode?

I'm booting it to update mode by pressing FN and the display stays blank as it should. Connecting to my PC, but the Firmware Updater from SMSL just doesn't show connected if I press connect. I have no idea how to update this thing.

You could try using a different USB port, for starters. Make sure you're running the app with admin privileges. Was the unit working in normal, DAC mode? Also, try using a different USB cable (in case you have a spare one at hand). By pressing connect, you're referring to the handshake icon, correct? You put it in update mode by pressing both the Power button and the FN button; are you doing the same?

By coincidence I succeeded to update the firmware process. The update manual is really ass. Version was 1.01 but are there newer versions atm?

It's strange when I connect my D400EX the audio device only shows "SMSL Audio Device", but when I connect with bluetooth the device shows as "SMSL D400EX...". Is it broken? At least USB input is able to play sound and music.

I have the same question, what is the latest version of the firmware? Is it IAP_D400EX_1v0_b20.hex? @asrUser where did you find the 1.01 version?
