Google has finally released the Android 5.0 Lollipop factory images for Nexus 4, 5, 7, and 10. These factory images were long overdue actually, but as is the case with Nexus devices, they are always forerunners when it comes to receiving the latest OS updates. With OTA updates still nowhere in sight, these factory images should help give interested users a head start and get up to speed with the latest version of Android.
According to the Android Developers website, along with the Nexus 5, Nexus 7 (2013) and Nexus 10 devices, the Nexus 6, 9 and Nexus Player have also received updated factory images. Interestingly the first generation Nexus 7 (Wi-Fi) also gets the cut, along with the Nexus 4.
If you are an experienced Android flasher, and have a Nexus 4, Nexus 5 (GSM / LTE), Nexus 7 2nd-gen (Wi-Fi), Nexus 7 1st-gen (Wi-Fi) or Nexus 10, here’s how you can have Android 5.0 Lollipop up and running on your device.
Note: This procedure will erase all data from your phone or tablet, since factory images essentially restore your device to an out-of-the-box state.
Requirements:
- Download the appropriate Android 5.0 Lollipop factory images for your device. Download for Nexus 4 from here, and Nexus 5, 7 and 10 from here.
- Nexus USB drivers configured and installed (Windows only).
- Nexus device with an unlocked bootloader.
- A computer with ADB installed and set up.
- Enable ‘USB Debugging’ in Settings > Development options, and plug the device to the computer. To enable developer mode on your Nexus device, simply follow our guide on: how to enable developer options on Nexus.
- Completely back up your Nexus device. Follow our: How to completely backup your Android device on PC without root access guide on how to do so.
