So I did this:
danman@silverhorse:~/Projects/LA104/tools/dfuload$ sudo mount /dev/sdc /mnt/tst
danman@silverhorse:~/Projects/LA104/tools/dfuload$ ls /mnt/tst
danman@silverhorse:~/Projects/LA104/tools/dfuload$ sudo cp ~/Downloads/system.hex /mnt/tst
danman@silverhorse:~/Projects/LA104/tools/dfuload$ sudo umount /mnt/tst
and after a restart I got white screen and:
[53532.958590] usb 2-3: new full-speed USB device number 73 using xhci_hcd
[53543.426569] usb 2-3: device descriptor read/64, error -110
[53543.666589] usb 2-3: device descriptor read/64, error -71
[53543.902667] usb 2-3: new full-speed USB device number 74 using xhci_hcd
from la104.
Try this hex file:
ds203.hex.txt
After copying the firmware image, the device should disconnect from USB and reconnect and a original file with suffix ".RDY" should appear if the file was successfully flashed. Do you see that file?

No progress:

danman@silverhorse:~/Projects/LA104/tools/dfuload$ sudo cp ~/Downloads/ds203.hex.txt /mnt/tst/ds203.hex
danman@silverhorse:~/Projects/LA104/tools/dfuload$ ls /mnt/tst

To sum up what we learned:
It was impossible to flash new firmware using DFU V3.11C, the device was not properly recognized or the file transfer was failing. We had to downgrade to DFU V3.10 using internal UART with stm32flash utility:
https://github.com/gabonator/LA104/tree/master/tools/stm32flash
For DS203 you need special image, not the one provided in release section. (build_ds203.sh in https://github.com/gabonator/LA104/tree/master/system/os_host)
When the OS was running, it was failing to run shell.elf. It just said "Image loaded at 0x0801f000". Building the image for different addres solved the problem (entry point moved to 0x08019000)
Running WebUsb (68webdrv.elf) - you need to reconnect the USB cable after running this app. Chrome notification should appear, but the communication on Ubuntu 18.0.4 did not work (Unable to claim interface in developer console). Problem was resolved by following command: "sudo rmmod cdc_acm" to release the system modem device driver.
