I've been trying to reset my phone. I've tried 12345, 0000, 00000 and nothing works. I've tried

echo root:$(grep -A 13 lock_code /dev/mtd1|tail -1):

and I got this code:

root:C/v1W3uW1oU12:

I've tried using john the Ripper both on the device and on the phone and cant get it to work. If anybody can give me the code, I'd appreciate it or tell me who to do it on John the ripper on my n900. Thanks.
