RAK4631 won't update to RUI3

I attempted to upgrade the RAK4631 to RUI3 firmware and was following the two step process. I am using the windows 10 cmd line.

  1. adafruit-nrfutil.exe --verbose dfu serial --package rui3_nrf52840_bootloader_latest.zip --port COM25 -b 115200 --singlebank --touch 1200
  2. nrfutil.exe dfu serial -pkg RAK4631_latest_dfu_package.zip -p COM25
    The second step failed with these errors. What else can be done?

c:\raki4631bootloadertoruiv3>nrfutil.exe dfu serial -pkg RAK4631_latest_dfu_package.zip -p COM25

It looks like you are flashing the wrong firmware RAK4631_latest_dfu_package.zip instead of rui3_rak4631_latest.zip

You are trying to flash an Arduino based firmware instead of the RUI firmware.

I pulled it from https://downloads.rakwireless.com/#RUI/RUI3/Image/ directory, strange that it is not rui3.
So I found your image, it works. Thanks.

The folder has both versions.
The correct files to switch start with RUI3*
