How do i recover my data on a Galaxy Tab after a factory reset? I forgot my password to unlock my Samsung Galaxy Tab, so I did a factory reset to get into it. Now I would like to recover as much of my previous data that I can. Is this possible? If so, how do I go about recovering it?
You still got your SDcard contents
You still got synced data on Google cloud associated with your Google account and other cloud services.
Everything else is wiped out and cannot be restored


All you can do is log in with same Google account on your device and it will restore some data from cloud like Google Contacts, Calendar and, maybe, settings for some apps. Purchased apps are still available from Google Play and you don't need to buy them again. Install Dropbox, Google Drive and other apps which store their data outside your device.

In future, try to keep copy of everything important on other device such as your computer or in cloud. Nowadays you can get lots of free storage on many services like Dropbox, Google Drive, Box, Skydrive etc. You can avoid wiping your device in future but you cannot avoid losing it or breaking it, so backups is very important.
