So currently I am using reppards CM7 ROM. I've been thinking of using the LG upgrade tool and going to a stock 2.2.2, now that it has been rooted (see here) and then rooting it. My phone started life with 2.2, and doesn't have the constant rebooting problems that some other have had. Also it's rootable with both z4root and gingerbreak 1.2. Basically, I'm thinking of doing this for several reasons: 1) just to try it 2) Thinking of starting from a fresh factory ROM again. I'm sure there are others but right now I can't think of them. I'm wondering, can I just hook up my phone as it is, and do the "upgrade" using the LG tool (I do have it down loaded and set up on my computer, though have never used it). Or, do I have to first go back to a stock 2.2 ROM. It's been several months since I first rooted and set up custom recovery, I don't know if I still have my first nand back up. I'm looking for thoughts and ideas. Thanks in advance.
