Ok lets do this, if you haven't unrooted yet then stay rooted or gt bk to root. My bad. I just came across a post, once you are rooted go to all things root and look forr the add ons and start stock files, sumone posted they flashed fro.m zvb to zvd with no problems, if that works then just maybe then lg update tool will work, bt like i said make sure u reinstalled everything after unistalled the drivers and re-download lg update tool to, n make sure you reboot comp after unistalling and reinstalling, ive not read that can make a big difference, let me know
its on 1st page in the all things root, go dwn till u see add ons then click, make sure wen u go to it ur on page one and u will c zvd file but do as instructions say, its nt like flashing a rom u hv to put in the cwm folder, hopefully the link is right if nt u should c it dwn bout 10 to 15 posts the link will take you there, or might hv to try the lgpnst
