You have to *enable* USBNet in the diags menu first (I don't recall the PW1 layout OTOH, but it's fairly self-evident. The K4 JB instructions on the wiki might help, since they essentially *require* doing that).

IIRC, the exact procedure is detailed in the RP's README, though.

(You also need the Rescue Pack installed before the CRP, or the sshd in diags goes bye-bye. In short: RP makes sure the sshd is there, working, and won't get killed; CRP allows you to boot to diags automatically when plugged in. Which means CRP alone is useless, and RP alone requires USBMS access to boot to diags).

A full update won't reset the fail counter.

A factory reset *might* but I don't know if it trips before or after the KNR check (and/or whether that check actually works at all on that FW/device).

There *might* be a way to do that from diags directly, though, assuming you don't fat-finger an "erase mmc" along the way p).
