Afaik, nv items for evdo, are not any calculations but can be referred as batch file / script to be executed in cw. It contains settings like ppp username password, hdr username password. Every handset may have same ppp credentials i.e net/net but hdr username is based on meid n hdr password is random number.
Now, if at all u know ur hdr credentials (which u can see in handset too) n keep it in safe place, u can input those settings manually provided u have cw 3.6 as older cracked version does not provide facility to input evdo parameters.
I guess u can also write using qpst/qxdm manually but i m not aware of process.
Hope ur doubts are clear.
Like the post if it helped u.
