No Blakey I'm not sure the kv matches the console. I'm trying to help someone out who is unsure of whether or not they used the "create ecc" function when writing to their nand. The fact that the console wont boot retail tells me no.
However, the console id shown in the xebuild output (in the jr window) matches what his console showed before writing ecc (he took a pic before attempting to rgh). In addition the serial matches what's on the case so I was thinking it may be accurate and I'm trying to figure out why the KV info window shows a different console id than what the xebuild window shows.
If he wrote an ECC image without first injecting the key vault (J-Runner does this for you now), the original key vault is lost and can't be retrieved unless he has a good NAND image from that console.
However, I am not 100% sure about this, so you might want to wait for Martin to confirm.
