So if I first use helium for backup and then do factory reset, then flash the stock 4.1.1.
I know google account has all my contacts and calendar.
After I have the stock 4.1.1 back I should be able to update to 4.3 and from there restore the backup?
Never used Helium. I have use Titanium Backup before. It's widely used for backing up app data. You can get it in the Play Store. Make sure you don't try to restore system data - it will cause all kinds of trouble. I don't usually restore app data anymore - well, now that I'm on stock I can't, anyway. I always had some kind of issue, whether it be small or big, when I restored data. who knows, maybe I wasn't doing it exactly right.
I'm not sure if restoring apps from 4.1.1 to a 4.3 base would be safe or not. remember, if you try, that means you'll have to root the 4.3 and that will trip your warranty bit count off of zero, so if you're concerned about warranty, you shouldn't root. (if you upgrade to 4.3 stock, you can go to download mode and see that they now have included two flash counts: one to count custom binaries (that can be reset) and the other one called warranty bit, that no one here knows how to reset yet.)
