REGIONAL COMPATIBILITY WARNING
This firmware update is strictly region-specific. If you own a Hong Kong (HK) or European Union (EU) machine, please refer to the previous guideline. Do not use the package detailed below.
Before downloading or starting the update, you must verify your machine's regional designation by checking the silver rating label on the chassis or packaging:
-
Australian Edition (10A): compatible with model KD-360X(BK/SL)AU.
-
Swiss Edition: compatible only with model KD-360X(BK/SL)CH.
Package Restrictions & Hardware Compatibility
Select the correct file for your specific region. We do not recommend cross-flashing or attempting to switch between different packages. Installing the incorrect firmware file can cause software conflicts, interface errors, or functional abnormalities.
Warning Regarding Physical Hardware Specifications
These firmware packages have been engineered specifically to fulfil local 10-Amp current limit restrictions and internal power configurations.
-
Attempting to install these 10A packages onto any other regional variant (such as HK or EU machines) will conflict with those physical hardware specifications, leading to system instability or permanent component damage.
-
Early Australian (15A) Batches: If you own an early-batch Australian machine built to a 15-Amp rating (featuring the wider grounding/earth pin), do not use this AU (10A) package. As per previous guidelines, those specific 15A configurations remain tied to the EU firmware package.
FIRMWARE DOWNGRADE RESTRICTION
Never downgrade the machine's firmware to an older version. Installing a previous firmware version may cause system instability, functional abnormalities, or permanent machine malfunction.
