Tone 2 pro firmware update issue

Hi , I just updated the Tone2 pro serial (11A00C1) with firmware tone2pro-xmos-hid-v1.41-221201
(default firmware should be v1.0) via my Windows PC.
Unfortunately , I saw your article for updating this (it should be upgraded with MCU , rite ?)
But I didn’t have that tool.
Please let me know where I could get this hardware tool ?
or any place to upgrade it .(I lived in Taiwan)
