Yes, do we need to go back to stock? I usually wait a while to do updates to my phone as it is past a year old aka out of warranty. I am just now trying to go to zve, and I don't remember having to go back to stock to upgrade to zvd, etc... I could be mistaken. The LG mobile software doesn't seem to be able to update my phone... I hate to have to do all this work just to put rom 2 back on, ha ha...
