When you upgrade to a new Android smartphone like the HTC One, you can have browser bookmarks, Wi-Fi passwords, and other settings quickly transferred over from your old device using your Google Account backup. However, you'll still have to download apps individually from your Google Play list, and not all of your saved progress will be transferred over.
Fortunately, there is a third-party app that will allow you to backup and restore your apps—with all their data.
Download the Helium - App Sync and Backup app (previously known as Carbon) from the Google Play Store and install it.
Note: You may skip this step if your HTC One is rooted.
If you're using Windows and don't have the HTC drivers installed, either download them from the ClockworkMod site or install HTC Sync Manager, which includes the drivers. Once installed, restart your computer.
Download and Install Helium Desktop from the ClockworkMod website and open it.
Open the Helium app on your HTC One. You'll be prompted to download Helium Desktop. Fortunately, we already did this, and if you're rooted, you don't even need it.
If you're not rooted, connect your phone to your computer via USB now.
You can back up everything or select apps individually, and you can select to back up the app with data, or just the data if you don't mind downloading later and want to save space.
Once you make your selection, tap Backup. Select either internal storage, SD card, Dropbox, or set up a backup schedule, and watch it work its magic.
You can also back up to your computer. Tap the menu button on the top right, and select PC Download. It will start a server and give you the IP address to put in your browser's address bar.
Navigate to this address in your browser and you will see a simple interface.
Easy! As you see in the screenshot above you can easily drag a backup into the webpage to...
To backup using the app, simply tap Restore and Sync and select where your backup is located.
Now you'll be able to recover your apps and app data if you upgrade or replace a damaged phone without spending hours trying to figure it out. For a walkthrough of the process explained above, check out the video below.
