NXH3670- Couldn't find kl device

When I use the NXH3670 flash tool, I could not connect to the dongle device, but I can connect to the headset device. The dongle device was debugged by the MCUXpresso IDE with the kl_dongle_sdk project successfully, I connected the device via the LPC LINK 2 for the debugging. After the debug process, when rebooted, the dongle could not be found by the flash tools or LP2 LINK2, I guess, maybe the bootloader lost. How can I reflash the bootloader, or Is there any method that can recover the dongle?
