I installed 2.1 when it came out using the instructions, but my Hero remains unstable. Freezes on every 3rd/4th reboot. So I decided I needed to re-install, but first I need to do a "real" hard reset. I remember reading on one thread - not sure where - to call Sprint Advanced Technical Services and they will walk you through a hard reset that uses some unlock number that only they posses. So I called. The first lady told me to type in ##365408# and then I followed her through a series of menus that got me nowhere. She transferred me to another CS rep who then transferred me to a 3rd rep who said just hit the Home-Back Arrow-Start keys, which I told him I did originally and wanted a "real" hard reset, not just clear all my storage. He then told me to go to Settings/Security where I would find a menu item for a hard reset, but there was no menu item. He was baffled-didn't know why it didn't show up. I got nowhere so I ended the call to use this forum. ***Can anybody tell me what a real hard reset so I can reload 2.1? Do I have to call Sprint Advanced Tech Support? What methods are really available and which work. Thanks.
