The app should detect the controller even in this state and prompt you to update the firmware to the latest version, which should fix the identification issue.
This alone will not fix the controller, but it is a necessary cleanup step after performing Method 1, 2, or 3 to ensure Windows recognizes the recovered controller correctly.

Sometimes a faulty USB cable causes the controller to drop into this low-level mode. br23uboot1.00
: Faulty USB cables or specific hardware failures can force the internal chip (often an AC5xxx or similar series) into this "USB download" or "UBOOT" mode. User Sentiment and "Review" Frustration
Sometimes the device is simply stuck in the bootloader loop. Unplug the controller from the PC. Wait for about 30 seconds.
Some users have reported that the repair software provided by vendors might be flagged as a Trojan or unsafe by antivirus programs. This is often a "false positive" due to the low-level nature of the firmware flashing tool, but always proceed with caution and ensure you are using software from an official source.

Jieli does not traditionally distribute its SDKs freely to the public; they are usually passed around under NDA to manufacturing plants. However, leaked versions of the have made their way into enthusiast communities.
—rely on these Jieli chips. Under normal conditions, the chip connects to your computer as an HID (Human Interface Device) controller. However, if the firmware fails, becomes corrupted, or if the controller is forced into a "recovery" mode, the chip reverts to a BR23UBOOT1.00 mass storage or bootloader mode.
: When in this mode, Windows typically classifies the device as a "USB Mass Storage Device" or a generic "USB Drive" rather than a Human Interface Device (HID) or gamepad.
Note: Security programs frequently flag these custom flashing tools as high-risk trojans due to how they access low-level USB registers. Verify the files directly with the manufacturer before bypassing your antivirus protections.
