Hi Leo

Which version of the nRF52840DK do you have?

Are you able to enter bootloader mode again?
Try to update the bootloader once more the same way. Give the device a minute before re-powering it (plug it out and back in. Make sure no battery is connected) after the new bootloader has been programmed.

Does it still show the same error after?

Hi Sigurd,

Thanks for your response!
I am not sure where to find the version of the nRF52840DK. The sticker on the development board shows PCA10056      2.0.1      2021.10     683083855

It still shows the same error after. I am not sure why Jlink keeps recognizing the firmware downloaded from https://devzone.nordicsemi.com/f/nordic-q-a/8144/i-can-t-update-the-j-link-ob-firmware-nrf51-dk is compiled in 2017. 



With the above being said, if I choose not to update the firmware in J-link commander, select no in the picture below.
I am able to flash the program properly.

Sorry, the link in the above comment is not correct. The firmware I'm using is downloaded here, www.nordicsemi.com/.../J-Link-OB-SAM3U128-V2-NordicSemi-170724.bin

Just to be clear:

So you do are able to use the nRF52840DK with this?
