How to Download and Manually Install Android 5.0 Lollipop on Android Devices
1. Download and install the latest Android SDK on your Windows computer. This installs two programs, ADB, and Fastboot, which can be accessed through the command terminal on your PC, as a part of the software development kit.
2. Add the SDK folder to the PATH by following these steps:
4. Tap Build number seven times.
5. Go to Settings > Developer options. Tick USB debugging.
6. Download the correct factory image for your device.
8. Connect your device to your computer over USB.
9. Start the device in fastboot mode.
The easiest way to do this is to hold a key combination while powering up the device. For Nexus 5, hold the volume up, volume down and power buttons while powering on the device. The full list of key combinations for different devices is here.
You can also boot into fastboot mode using the ADB tool: With the device powered on, go to the command terminal and execute the following: adb reboot bootloader
If needed, unlock the device's bootloader through your computer using the command terminal and executing: fastboot oem unlock
1. Open a command terminal and navigate to the unzipped system image directory.
2. Execute flash-all.bat, which was a part of the unzipped image file. This script installs the necessary bootloader, baseband firmware(s), and operating system. For this to work, you need to have added the folder where ADB and Fastboot are installed to the system's path as described in step 2.
3. When this is done, Google recommends that you lock the bootloader for security. You can do that by booting the device in fastboot mode while still connected via USB, and using the command terminal to execute: fastboot oem lock.
That's how you can install Android 5.0 Lollipop on your Nexus device. We still recommend that you just wait a while until the OTA update arrives on your device.
