Default Zte z998 rooting without a pc.

Hi everyone if this has been discussed before feel free to redirect me, OK I've tried framaroot 1.4.1. With no luck, poot debug apk no luck there either, I have no p.c. atm so I need to know if ANYBODY can help me root a d install cwm on this thing without a PC. I've done it with my daughters centura galaxy and hydro xtrm, I just can't make it happen with this one. Please help as I really love root and all the benefits it brings. Pm or comment I will reply either way and thanks all in advance!
