While testing DFU for OTA ,after entering bootloader mode on my nRF52840 DK, the device doesnt show up either in the device manager or using nRFconnect and Jflash lite .
when I turn the DK on and off normally (without pressing the reset button), the LD5 doesnt blink or turn on otherwise.
If I turn the board on while holding reset, BOOTLOADER shows up as a USB device, and the LD5 blinks. I see a folder for USB detection in My computer only for a second and then it vanishes. Can anyone help me how to recover my board?
Thanks in advance.
