I have not tried rooting the phone or anything out of the ordinary to cause this. One day it just would no longer go past the LG screen. If it matters, I am on Sprint. I have tried doing the hard reset by holding volume down and power and I do get that menu. I am able to clear cache. I am unable to upgrade from SD card because I do not have update.zip. When trying to format, I can choose to delete all data and then it freezes. Could someone give me some ideas or step by step what to do??? I appreciate any help. Thanks in advance.
