Portable ZWA-2 firmware trouble

[ross0201]

I’m not able to finish the firmware install for the portable experiment on the ZWA-2. I can flash the firmware but when it tries to connect after the power cycle to configure the WiFi I get this message: “An error occurred. Improv Wi-Fi Serial not detected”

On Windows 11 I’ve tried Chrome and Edge and gotten the exact same result. Chromium on Ubuntu didn’t work at all.

I can flash back to the original firmware but if anyone has any ideas on the portable version I would appreciate it.

No idea about any “portable version”, but the ZWA-2 has had some firmware issues recently…

ZBT-2 breaks with update 7.5.1.0

I did update my ZBT-2 through Home Assistant to 7.5.1.0 and it returned error and break everything. When I did re-flashed it with Install Firmware – Device Toolbox to 7.4.4.6 it works again. My understanding from this is that Home Assistant can’t install 7.5.1.0 and I have been searching for the installation file for 7.5.1.0 so I can upload it to the toolbox and update the zbt-2 manually but I can’t find the file. Do anyone know where to download it?

I had the same issue but when I clicked on retry, it popped up and let me continue on to input my WiFi credentials.

Thanks! I did it 5 or 6 times but it did eventually go.
