Question

How and where do I add the tickmark again? Will I have to reset my Nexus 7? If so are all the app I bought then lost?

If youre talking about applications (.apk) downloaded from google chrome and not the play store then you need to go into Settings > Security > Unknown Sources

A: As Flow said, you can recover them from Google Play store later on. If you feel not safe, use AppSaver to back them up.

Resetting your android phone

Before resetting your phone, you have to save your data (pics, music, movies, contacts...).

• If you have a google email account, saving your contacts is not needed, you can just sync it to the cloud.
• Concerning your apps, as Flow said, you can recover them from Google Play store later on.
• Backing up pics, movies and music is necessary. I recommend you to back up your entire data storage, it contains apps private files, office documents, few stuff that you could easily forget to back up otherwise...

When those steps are done, you can safely reset your phone, it will be like a second life for it :-).
