Yealink EXP50 Custom Logo/Wallpaper

[smaloney]

Is there any way from within the admin console to specify custom wallpaper for the EXP50 (sidecar) such that it won't be overwritten on reprovisioning?

I'm aware it can be done through the phone's web config, but it's obviously not "sticky" past reprovision/update.

We're running enterprise license; V20.

Not any supported way. You would have to go with custom template or at minimum remove the provision link from the phone so it doesn’t update.

Reprovision will be required for the device to perform and new updates required.
This might require a custom template but keep in mind that it is not supported and we will not be able to advice is support is requested.
