Firmware won't upgrade to handset
L.s.

Given 3CX Specifications, I need to upgrade the firmware for yealink W52 base and handhelds. We need this for the Multi handset provisioning, new in the 3cx v15 pbx.

De base upgrade went without problems.
The handsets, however are a problem.
THew current handset firmware is 26.50.188.1 and we need to upgrade it to 61.80.0.15. Since upgrading trough the website of the base does not work,

I wanted to try to upgrade the firmware using an usb cable I did download the W52x Firmware Update tool. I put all the files in the root directory. However, when i try to upgrade i get the message: " Bootloader is to new to support File system, skip update"

Since we only have windows 10 Devices here, in compliance wiht iso policy, downgrading of the windows system is a no go.
[/php]
So how can i upgrade the handsets?
