Update EHS36 With T48G?

[bappleby]

Hi,

I have the following,

Yealink T48G with firmware 35.73.0.40 (Hardware 35.0.0.0.0.0.0)
EHS36 with firmware 1.16.0.0 (Hardware 48.0.0.0)

I am trying to upgrade the EHS36 firmware, the How to upgrade document V2.0 doesn’t specify the T48G as being able to upgrade the EHS36 but a lot of the forum posts are now quite old (April 2014) and I believe that 73 is a new version of firmware.

I found that the firmware appears to have the upgrade functionality, I was able to configure the Zero Touch DSS Key and it all appears to work. I am making an assumption here that version 73 Firmware has some upgrade ability?

After pushing the Zero Touch or rebooting I receive the Update Expand screen where I select OK. However I don’t get the Please Insert Expansion, I instead get an 11 step configuration screen and the option to press Next.

After pressing Next I then get the Auto Provision screen requesting a URL, User Name and Password.

Can I upgrade the software with this combination of Hardware and Firmware?

Cheers,

Brendan
