| Issue | Operating System(s) | Workaround / Solution | | :-------------------------------------------------------------------- | :------------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | USB drive doesn't appear after holding the button and powering on. | Windows 10/11 | This is a known issue with some devices. The solution often involves trying a different USB cable, a different USB port (especially a USB 2.0 port), or a different computer entirely. | | Copying the _system.hex file results in an .ERR file. | Windows (especially Windows 7) | This is almost always resolved by using the method described above. It's the most common fix and is highly reliable. | | The DFU drive works, but copying the firmware seems to hang. | Windows | This is normal behavior during the "copy twice" method. Allow the transfer to continue; it may appear frozen but is actually writing the firmware. | | DFU drive doesn't appear on modern Macs (OSX). | macOS (Intel & M1) | The mass storage copy method is not supported on OSX. You must use the dfuload command-line tool to flash the firmware successfully on any Mac. | const char* menu_tools[] = "Logic Analyzer", "I2C EEPROM

Try copying the file again. Some users report needing two attempts on Windows 11 for the flash to "stick". Disconnect: The solution often involves trying a different USB

The LA104 is a perfect example of how open-source software can transform good hardware into an extraordinary tool. While its official firmware is perfectly capable, the alternative open-source projects built by the community unlock a level of versatility and power that will surprise you. Whether you want to decode wireless signals, build a web-based oscilloscope, or explore embedded development, the LA104 and its vibrant developer community have a solution waiting for you. It remains a compelling, low-cost, open-source platform that's as fun to tinker with as it is useful for debugging.
