I installed the tethered mode hack on my 700p (although when I check the installed file name in ROM, it does not say hacked version).

I paired the phone with my computer.

I clicked on DUN in my BT places and entered #777 for the phone number.

After a while I get error 678: remote computer not responding.

Then I tried logging into power vision with blazer before clicking on DUN.

I got error 692: hardware failure in modem, and my phone would freeze for a couple seconds and when it came back online, it was no longer connected to powervision (because when i went to a blazer website, it went through the whole login process again).

I have spent a lot of time on all this, so explain what I am doing wrong step by step as if im a small child.
