Hi Alejandro,
sorry for the delay.
I think the information you need are described in the following links, which i followed:
http://nerdvittles.com/index.php?p=149http://fonality.com/trixbox/forums/trixbox-forums/trixbox-endpoints/cisco-7970-programminghttp://www.greenwireit.com/a-guide-a-faq-how-to-unbrick-the-cisco-7970g/http://www.greenwireit.com/tag/xmldefaultcnfxml/The tftp and dhcp program for windows is the tftpd32 (works really well).
The XmlDefault.cnf.xml i used for the update is:

I did try for some days, without success, until i've found the post
telling that the cmtermxxxxx.zip would not work, but with .cop it would,
so i did try it... and it worked, in 5 minutes the cisco was updated.
The configuration to do it in the easy way: windows box, a switch or hub
(not router) and the cisco.
I hope it works for you.
BR,
Paulo
