A lot of people on the web have reported a loss of performance and autonomy on their Huawei P9 Lite after upgrading to Nougat with EMUI 5.0.
In some cases, the stability of the system has worsened and the demand to downgrade to Marshmallow has grown up day after day.

Fortunately, unlike what is happening with other brands, so-called downgrading of the firmware can be done to come back to the EMUI 4.1 based on Android Marshmallow without any particular difficulties and above all, without invalidating the manufacturer’s warranty.

Prerequisites

  • The downgrade procedure will automatically reset your phone, so you must back up all the data before proceeding
  • You need to get a microSD of at least 8 GB
  • Before you start the procedure, you must have the smartphone battery at least 60%

Procedure

  • First, download Android Nougat Rollback Package for Huawei P9 Lite that you can find above and extract it.
  • Now create a folder dload in the root of your SD card and place the update.app file in that folder.
  • Now turn off your device.

After coming back to EMUI 4.1, you will have to resetup smartphone.
Of course you do not have to upgrade to EMUI 5.0 otherwise you have fired the whole process.

At any time, however, you only need to accept the upgrade to get the latest version.

We remind you that it is always good to do the latest updates because they bring security patches that keep you safe from the latest threats and critical discoveries.

However, having a non-upgraded product does not expose you to any major risk, as long as you always install applications from trusted sources, preferably always from the Play Store.
