Explaination by N2CardGuy:

"Well I thought I could give you guys out there some insight into how to get that DT08 app working with your own Data. I recommend plugging in
Penga's data first to see how it works but here is how to do it with your own data. Lets get this ball rolling.

You will need the following:
DT08 (The calculator just released)
TRex Nagra 2 Tools
A subbed Yellow card (Rom101 or 102)
Iso Programmer

How to DT08:

1) Connect up your Iso
2) Open TRex and click Open Port
3) Click on the Comm Tab
4) Enter the folowing in the Cut and Paste section or Copy and Paste 21 40 09 A0 CA 00 00 03 22 01 08 55 7F
5) Press the Send it button.
6) In the data window you will see a response That is your DT08 you need.
7) Scan across until you find the Number 49. Right after that will be a 80 or possibly a 00. From there to the end is what you will paste into DT08
in the 73 bytes from dt08 area.
8) Open DT08.exe
9) Enter or paste the data in the 73 bytes from dt08 area.
10) Now fill in the ird Boxkeys and Cam ID of the card you read from.
11) Press the swap byte buttons for gpPKeyPub and gpPKeyPubBeta.
12) press the RSA button.
13) Press the IDEA button.
14) Press the Check Sig button.

If you followed my steps exactly then the Field beside Check Sig should match the first 6 Bytes off the 72 bytes IDEA Decrypted. If so, you have
the first part of the data needed to use your own Info on ROM102 to ROM10.

This is a post from Protech-equip. I was an avid member of this forum until I decided to damage the community and these very forums in several ways. One of these was by spreading unfounded rumours and lies about the admin here. Another was be editting hundreds of posts I made here with some useless text. The ironic thing is that I actually made a lot of money selling various pirate devices through this very website.

I could have easily chosen to email the admin and ask him to zero out the IP's or even delete my account but decided I would damage the forums and talk shit about the people here instead.

I should be ashamed of this but am likely not.

Thanks for scouting this out Ctech... I will give this a go.:)
