In order to restore purchase on a Google Play Android device, the device MUST be tied to the same account that originally made. This is a restriction by Google to limit piracy. While we can’t change the rules, if you do have a device that is already tied to a different Google account, you may still be able to restore purchases from a different Google account if you do the following:
- Go to Android’s “Settings” area. (Where this is depends on the device, but it can often be done by going to the home screen, then pressing the “Menu” button).
- Choose “Accounts & Sync’.
- You should see something that says “Manage Accounts” where you can add and remove accounts. If it’s not already in the list, add the account that you originally used to make the purchase. Then pick then account that you originally used to make the purchase.
- Now you should be able to restore purchases that were made previously.
Once the restore is completed, you can switch the the device onto another account if you wish.
