Uninstall old VCOM drivers and install the signed MTK drivers. Stable COM port identification.
The Boot ROM (BROM) is an immutable read-only memory chip on the MediaTek SoC. When a device is powered down and connected to a PC via USB while holding the volume keys, the BROM initializes before the Android OS or preloader can load. It opens a brief communication window to accept firmware instructions.
To diagnose the issue effectively, it helps to understand what happens inside a MediaTek device during ignition: brom protocol error check device environment

The phone is not completely powered off or is in the wrong mode (e.g., Preloader instead of BROM).
Interpretation : The device's internal clock PLL was not locked when the BROM tried to switch to high-speed USB mode. This often happens if the device was previously in a deep sleep or a capacitor is discharging. : Disconnect battery for 10 seconds, reconnect, and retry. When a device is powered down and connected
indicates a communication failure between the computer and the device’s Boot ROM (BROM) mode, preventing tools like the SP Flash Tool from interacting with the internal memory Core Causes Driver Issues : Outdated, incorrect, or unsigned MediaTek USB VCOM drivers often prevent proper device recognition.
