Devices rarely switch to a bootloader state voluntarily. If your device displays this string in your system settings, it is usually caused by one of three culprits: 1. Corrupted Firmware
Based on the filename , this appears to be a system firmware file (specifically a U-Boot bootloader) rather than a consumer product you can buy or a game you can play.
Unplug your peripheral, reboot your computer, and plug it back in to force a fresh hardware poll. Method 3: Official Vendor Firmware Reflashing br23uboot1.00
Locate the small reset hole on the rear side of the casing (usually next to a central screw hole).
When connecting a custom microcontroller development board or a broken Bluetooth device to a computer, Windows Device Manager may display an unknown device or a specialized USB device with the hardware ID or description matching br23uboot1.00 . Tools for Interfacing with BR23 Firmware
The device is waiting for a new firmware file to be "written" to its internal flash memory. : The Vendor ID (VID) associated with this

A firmware update through the GameSir App was interrupted.
A fallback system built into the chip's Read-Only Memory (ROM). When something interrupts the normal boot sequence, the processor halts execution and opens a basic serial/USB pipeline to allow manual firmware flashing via the jl-uboot-tool GitHub project . Why is it Named BR23UBOOT1.00? The name can be broken down into three distinct components:
I came across while trying to revive an older embedded board (looks like a custom U-Boot build for a BR23 reference platform). Flashed it via JTAG, and it fired up immediately – no bricking, which is always a win.
