When you open the folder, you'll notice that each subfolder has the prefix Yo in its name. Change the name of each folder. You can rename the WhatsApp folder, then install the official WhatsApp app and log into your account. When you are asked if you want to restore the backup, click Restore. All of your chat and media files will be restored to their previous state.
Note that the entire process should be done in network state. So you need to check if the network is enabled or the program won't work.
