The S905X4 processor is powerful, but firmware tweaks can improve heat management and UI snappiness.

Updates are typically delivered via notifications on the device.

Updating the Mecool KT1 firmware is a relatively straightforward process. Here's a step-by-step guide:

If an update is found, ensure you have a stable internet connection and do not power off the device. 2. Manual Update (Local) Use this if you have a .zip update file on a USB drive. Copy the update.zip to a FAT32-formatted USB stick. Insert the stick into the KT1.
