The identifier "BR23UBOOT100" refers to a specific bootloader state for Bluetooth microcontrollers (SoC) manufactured by JieLi (Zhuhai Jieli Technology). When a device appears as a "BR23 UBOOT1.00 USB Device" in Windows Device Manager, it means the hardware is in a low-level "USB download" or "ISP" mode. This state typically occurs for one of two reasons:
Failed Firmware Update: The existing firmware is corrupted or missing, causing the chip to fail its normal boot process and drop into this recovery mode.
Manual Trigger: A user or technician has intentionally triggered this mode (often by shorting specific pins or holding a button during power-on) to flash new firmware. Affected Devices
This bootloader is commonly found in devices using JieLi AC695x series chips, including:
Gaming Controllers: Notably the GameSir G7 SE and Lenovo Legion Go controllers, which may enter this state if their internal Bluetooth receiver chip crashes.
Bluetooth Audio: Cheap Bluetooth speakers (like Borofone BR23) and generic TWS earbuds. Troubleshooting Guide: How to Exit or Fix
If your device is stuck in this mode and not working, follow these steps: Standard Reset Disconnect the device from USB. br23uboot100
Hold the Power button for at least 10–15 seconds to force a full power cycle. Reconnect and check if it is recognized correctly.
Firmware Reflashing (Technical)To restore a device in this state, you must use JieLi-specific programming tools on a Windows PC.
Required Software: You generally need isd_download.exe and a matching br23loader.bin file provided by the device manufacturer.
Third-Party Tools: Open-source projects like the jl-uboot-tool can be used to read, write, or erase the flash memory of these chips.
Specific for GameSir/Legion Go: Check the official support pages for the GameSir G7 SE or Lenovo's controller firmware update utilities. They often provide a dedicated "unbrick" tool that detects the BR23 UBOOT device and reapplies the correct firmware.
Hardware CheckIf the device repeatedly enters this mode, there may be a hardware fault with the SPI flash memory chip or the main SoC itself.
