There are two main ways one can get the NANDroid Backups to work on the Samsung Galaxy A7 smartphone: using the ROM Toolbox by J. Rummy and installing a custom recovery such as TWRP Recovery or ClockworkMod Recovery. The NANDroid option is always one of the main perks of installing a custom recovery, but it isn’t necessary if you are installing the all-in-one ROM toolbox application either from the Google Play Store or its official website home presented by the developer, J. Rummy.
Regardless of the way you have conjured up your ability to now take NANDroid backups, you can install the NANDroid Manager application and manage those backups you took. The NANDroid manager application offers a cool feature where you can choose to just restore your applications and nothing else instead of restoring every partition. It’s not just apps either. You can do the same for any of the partitions that were backed up, including the pictures if you would just like to restore your pictures.
The NANDroid manager application is available for the Samsung Galaxy S7 smartphone right after you finish the guide after the drop.

Rooting the Samsung Galaxy A7 SM-A700H running on Android 5.0.2 Lollipop
- Enable the USB Debugging Mode on the Samsung Galaxy A7 smartphone so it can connect with the computer and its programs.

- Wait for at least a couple of seconds and then look at the Odin application for a blue or a yellow ID: COM port lighting up. No port light up means that your drivers are not working. You can install the universal Windows ADB Driver if you need to fix that problem.
- Click the AP button and then browse the desktop for the CF-Auto-Root file.
- Once uploaded, click the Start button from the Odin application and the flashing tool will do the rest.

In conclusion, that’s how to root the Samsung Galaxy A7 SM-A700H device running on the Android 5.0.2 Lollipop update. You can check it worked by installing the root checker application from the Google Play Store. Keep the root checker app on your device for later so you can also check if your device is unrooted if you ever device to flash the stock ROM.
Remember that you should not be accepting over the air updates on your Samsung Galaxy A7 smartphone while it is rooted. Download the official firmware file from the Sam Mobile website and flash it with the same Odin application using the same method as above. Anyone with an unlocked device can flash any firmware. However, people locked to a certain carrier network will need to find the firmware that is given by that same carrier or you will soft-brick the device.
