A new update has been rolling out for the Galaxy J7. This brand new update from Samsung will take the device to Android 5.1.1 Lollipop firmware. The update, along with a new Android version, brings lots of security and bug fixes. Stability improvements can also be seen with this firmware.

The listed firmware comes with the build number J700FXXU1AOK2. Although it is still Android 5.1.1 Lollipop based, it is a critical update for the device. As the update is running slow, so you can either wait for it to hit your device or just flash the listed firmware right away.

Moreover, if for any reason you have installed a custom ROM or have heavily modified the firmware, then you must restore the firmware to stock, in order to receive future updates from Samsung. This guide can also be used to restore your Samsung J7 to stock Android 5.1.1 Lollipop firmware.

To update your phone to the latest firmware, you need an Odin software made available to the Samsung Galaxy users for flashing a range of things including firmware, custom recovery, CF-Auto-Root and more. So if you are new to the installation process, then we have got you covered. Let’s begin with the tutorial.


  • Make sure you have the perfect device and variant. This guide is compatible with only Galaxy J7 SM-J700F variant and for others this won’t work as the firmware J700FXXU1AOK2 is device specific.
