How to install B151 Emui 5.0 update based on Android 7.0 on Huawei Nova Plus

The Chinese smartphone manufacturer Huawei announced the Nova and the Nova Plus smartphone at IFA 2016 conference in Berline. While the smartphones were announced at IFA, both the Nova smartphones are only available in China as of now. The smartphone looks premium, however, from the inside, we are looking at a mid-ranged device. The smartphones are being offered by the company in two variants, i.e. 3GB and 4GB that cost roughly about $310 to $355 with the current exchange rates.

Both the Huawei Nova and the Nova Plus are running on Android 6.0 Marshmallow out of the box and we don’t have any wording on the Nougat update for the same. Hence, if you own either of the Nova smartphones and you wish to run Nougat on them, then your only option is to flash it manually as the OTA may take a lot of time to roll out to everyone. Huawei is currently testing out the EMUI 5.0 beta for the nova devices for a couple of days now. This version of the software runs on Android 7.0 nougat.

About the smartphone

As mentioned earlier, Huawei announced the new Nova smartphone at IFA 2016 and they sort of fall under the mid-ranger category of smartphones. Now talking about the Nova Plus smartphone, it sports a 5.5″ display on the front with a resolution of FHD. This is an IPS panel with a screen-to-body ratio of 72.6%. Inside is a Qualcomm MSM8953 Snapdragon 625 which is an octa-core processor which runs along the Adreno 506. Also, the smartphone comes with 3GB of RAM and 32GB of internal storage, which can be expanded upto 256GB via microSD card. On the camera side of things, we are looking at a 16MP rear-facing camera with an f/2.0 aperture and on the front, there is an 8MP front-facing selfie shooter. There is also a 3340 mAh battery powering the entire smartphone.

  • Before you start the setup process, make sure to cross check the model number and CUST version of the software which you are about to install.
  • Also, before you begin the setup, make sure you create a backup of the data which is inside your phone. Since this setup requires a clean wipe of the device, you will end up loosing everything if you don’t create a backup.
  • You also need to make sure that your device has about 50-percent of charge before you begin the process. If your phone’s battery drains during the setup, then you may end up with a dead phone as well.
