Hi i am setting up a vcore4 standard kit and the documentation took me to rat0s 2.0 for some reason. I did not realize this was the old version at first. i got as far as flashing the toolboard and then realized there was no vcore4 config available in Mainsail. So after some searching I was able to find os2.1 and tried to flash that. It has failed everytime on 2 different pcs and 3 separate downloads. Did this process cook the sd card? Balena gets all the way through verification then reports the flash failed.
