Default [Q] unable to get root on Commtiva N700

Hi I am trying to root a Commtiva N700

I've tried all sorts of versions of super one click newest to 1.7

Z4root / visonary /gingerbreak do not work

I've even done the copy adb to the superoneclick folder

it's running android 2.2 os but i can never manage to root it

any one got any suggestions?
