Android 5.0 Lollipop is slowly coming to many devices. The problem is that this version of the operating system is far from unanimous, and does not appeal to all users accustomed to KitKat, especially with regard to design. If you have updated your Nexus, either manually or by OTA update, and want to go back to Android KitKat, check out a tutorial for downgrading Nexus 5, Nexus 7 and Nexus 4.
How to downgrade Android 5.0 Lollipop on Nexus
Downgrading your Nexus after an upgrade to Android 5.0 Lollipop is quite simple, especially if you have manually installed the firmware using a factory image. For some manufacturers (see Samsung and its Knox) ??downgrading can be quite complicated, but for Nexus the process is easy!
Start by choosing the factory image you want to install (ie a firmware). We will use Android 4.4.4 KitKat for this tutorial, but nothing prevents you from using an older version. Just choose the version of Android for your Nexus device on the Google Developers page.
As always, it doesn't cost a full backup before the process. If you have root permissions, back up the system and copy it to your PC.
Note: This procedure has some risks. Neither I nor AndroidPIT is responsible for any damage to your device.
1. Copy the firmware to the folder containing ADB and Fastboot and unzip the two files until you get a folder flash-all.bat.
2. On your Nexus, enable USB debugging: enable developer options on Android and check USB Debugging;

8 Choose from the Recovery menu the option to option wipe cache partition with the volume buttons and confirm your choice with the power button;
