Using HKL-LD2402_TOOL(v1.0.1.9) and a ch340 to flash 2402_335_OTA.bin onto an LD2402 failed.
After this the LD2402 stopped working, and "Obtain Firmware" under "Update FW" now says "Current Firmware: BootLoader".
Pressing "Flash" just gives the error message: "Failed to send bin file information, error code: 2"
What is error 2, and how can I fix it? Can the device be flashed normally even if it's in some bootloader mode, or will it require something else?
