Flashing ROMs: Am I "Doing it Wrong?"
You should be careful when restoring apps from titanium. That software not only backups the apk itself. It backups the data of the app too. That's all it does. If the app you backup is programmed to run different accordingly to Android version and you change it with another rom and then in your new version you restore the app initialized to work with previous version, wel... errors will popup. For the rest, I do exactly the same as you except for the titanium backup. I only backup the Wi-Fi saved networks and their passwords. Not even Whatsapp databases because they're saved into SD card and the factory reset (and the dalvik cache and data format) doesn't erase it, so when I reinstall Whatsapp then the app finds magically those databases. I also backup saved words of Swype and messages (but not the messages app and its data like titanium does! ) But those things are for commodity. The rest I just delete all! New rom means new air. I ever loose little things, but saving contacts and notes in the cloud its far enough.
