dwhitley0381 Posted July 20, 2007 Report Share Posted July 20, 2007 I just got my disk and I can confirm you have to enter a password for authentication and that is based on your units device number. I will be be loading it later today and will keep you posted. Quote Link to post Share on other sites
dwhitley0381 Posted July 20, 2007 Author Report Share Posted July 20, 2007 Ok I just got my password. It stats that the media will only work with my device number. Now Iam not sure all that seeing that I have a CD and there is no way that it would be made for my unit and only mine. I would think you could upgrade with this disk and just use the password that I got. However the disclaimer says if you send it in for service they will not repair if you have a different device number then the software upgrade in their database.

KIDD Posted July 20, 2007 Report Share Posted July 20, 2007 u have a PM Quote Link to post Share on other sites
pDawg Posted July 20, 2007 Report Share Posted July 20, 2007 From the activation site faq: Q: I receive the message, “Media Number already in-use.†A: Please confirm that you are using the correct Media Number located on the Media Number Card bundled with the update disc. Each Media Number is unique and cannot be used to update multiple Pioneer navigation systems. And from the detailed walkthru: ** NOTE ** This password is unique and can ONLY be used with this Device Number and Media Number combination. Quote Link to post Share on other sites
dwhitley0381 Posted July 20, 2007 Author Report Share Posted July 20, 2007 Yup... did you use someone elses copy... I think you would need the password they got to unlock the DVD Quote Link to post Share on other sites
pDawg Posted July 20, 2007 Report Share Posted July 20, 2007 You put in the media number and your serial number, this generates a unique password that will only work on your serial numbered unit. And obviously once you register a media number to a serial number you can't use it again. So unless someone comes up with a keygen, a copy of the disc is useless to Z1 Owners.

dwhitley0381 Posted July 20, 2007 Author Report Share Posted July 20, 2007 Ok I see.. the DVD contains passwords for all Z1's made out there and the server knows the passwords which then allows to install... I was thinking once you got the password it would work on all units but it relates to the IS of the Z1... hmmm Well I am upgrading mine when I get home tonight.. See what happens...

pDawg Posted July 20, 2007 Report Share Posted July 20, 2007 So I don't think the DVD has all the passwords for every Z1 ever made, but I do think that it has an algorithim that can take the password and extract the serial number from it, then it can compare to the serial of your unit and work or not. So the whole reason you even generate a password (other than just supplying one with the dvd) is so that they can take the media number and your serial number and run it through whatever algorithim that generates the password for just that reason, so you can't pirate. If someone figured it out they could build a keygen that would allow you to make a valid password based on the media number and your serial. Quote Link to post Share on other sites
Hyperite Posted July 20, 2007 Report Share Posted July 20, 2007 If more than 3 people send me their media ID, device ID, and password, I think I could crack it. Quote Link to post Share on other sites
pDawg Posted July 20, 2007 Report Share Posted July 20, 2007 Well there you go. PM Hyperite your info and let him go to work. It doesn't matter if you give it to him because it only works on your unit. But with enough info he might be able to reverse engineer the algorithm. Quote Link to post Share on other sites
shoaf213 Posted July 26, 2007 Report Share Posted July 26, 2007 Couldn't you just spoof the hardware ID, like MAC spoofing? Quote Link to post Share on other sites

shoaf213 Posted July 27, 2007 Report Share Posted July 27, 2007 Hell, I don't know, I'm not a coder, but, that's similair to the Vista WGA crack....It spoofs the BIOS version I believe. Just seems easier, in theory, of course.... Quote Link to post Share on other sites
