: If you experience issues with Bluetooth calls, the fix is not to reinstall the ROM but to adjust the MCU's Bluetooth settings. Go to Settings -> Factory Settings , enter the code 126 , navigate to the Application tab, and change the BT option from "IVT_BT" to "WQ_BC6". This is a known MCU-level tweak that resolves the problem on many KLD6 units.

Additionally, the update unlocks the previously dormant . While not fully utilized in the current release, this suggests that the hardware is being prepped for edge-computing capabilities or local data logging in future updates, which is an exciting prospect.
While still the stock KLD skin, it often appears slightly more responsive to touch input. Go to Settings -> Factory Settings , enter
Unlike a standard Android OS update, which upgrades your apps and user interface, an MCU update targets the physical hardware interface. The V3.06 update directly manages:
The centerpiece of the v3.06 patch notes is the fix for the "Latch Loop Conflict." In previous iterations, when two logic threads attempted to write to the same holding register simultaneously, the system would default to a "null" state, potentially causing safety shutdowns.
