I have a new nRF52840 Dongle which seems to have either had a hardware failure while updating its bootloader or the updating was unsuccessful and now the device does not flash the red led, what can I do to update the bootloader or test the hardware?

Hi,
I got the same issue, but it gets to blinking mode arfter pressing reset button.
Check the manual here.
Thankyou, that sorted it out
would I be able to program the nRF52840 Thingy using Segger and DK, I have not checked yet but did find the problem encountered above trying to program via the USB
apparently it has the same issue, now to get a programmer for the two Nordic units I have
at least one per day on this public forum
a mere 4 hours later:
Thanks for that awneil, I will mention this internally.
Are you referring to the Thingy:52 or the 52840 dongle when you write 52840 Thingy? If you want to program the 52832 Thingy:52, you can either use DFU via the Thingy app (iOS or Android) or via the debug out port on the DK & a SWD cable. The documentation here could also be helpful.

I was hoping to program via the USB port on the Thingy 52, but I see from the documentation that it is only for charging the battery
Yes, the USB is only for charging. You will need to do what I explained in my last comment to program or upgrade the FW. The reason is because the Thingy:52 does not have an integrated Segger J-Link chip (unlike the DK, which does).
