Hello,

I tried to flash AkosLukacs's hex file from this page to my nrf52840 dongle using nrfutil:
```
nrfutil pkg generate --hw-version 52 --sd-req 0 --application espruino_2v04.160_nrf52840_dongle.hex --application-version-string "2.4.0" dfu.zip
nrfutil dfu usb-serial -pkg dfu.zip -p COM5 -b 115200
```
it says that the device was programmed succesfully, but I can't connect to it (I do not see any BT device nor any COM port I can connect. the only port I see is the one I used for programming showing nRF52 SDFU USB (COM5))

any hint what can be wrong ?

thank your any advice...

@k.zabloudil

I am at the same step. Flashing bootloader seems fine. I think windows probably needs a driver. Will look a bit more.

Just occurred to me that the problem is probably that I have never ran an official Espruino device. The driver that would normally install on first run is probably not installing. Will try that.
