I was able to make a full nand dump (16mb) from a Falcon board and using a Raspberry PI 3b+
My plan was to mod it to RGH3 but when I went to upload the ECC/XELL image it didn't boot anymore, power light came up for one second and it turned off. I also attempted to re-flash the original nand dump but that didn't make it work either so I had my xbox dead for a couple of days.
Regardless I picked up a Raspberry Pico and was able to restore the original nand dump I made with the RPI3b and went back to life, after that I was able to complete the RGH3 process so that's something.
