HEH not respond when plugged into usb after flashing. AWWW. Yes this is it what i expected. I guess that i bricked it. All leds not respond and doesn't see device.

This E104-BT5040U is a pca10059 clone.
you can use jlink or other link flash uf2 bootloader first:

JLinkExe -If SWD -Speed 128 -Device NRF52840_XXAA
loadfile pca10059_bootloader-0.8.3_s140_6.1.1.hex

then build a nrf52840_dongle_dfu opensk firmware.
It works.

It's hard to carry it without a enclosure,but its original enclosure is useless because i can't press the buttons when it has the original enclosure on,so how to get a suitable enclosure？
