Nexus 4 and Nexus 6 are among the lucky few Android devices to receive quick Lollipop updates via Over-The-Air (OTA) as well as through Google's factory images at such a short notice.
Those who faced issues with the OTA update can try downloading and installing the factory image manually, before rooting the device or installing third-party custom ROMs on it.
Key Points to Remember
- Back up all important data and settings of your Nexus device via recovery mode.
- Ensure the bootloader on your Nexus device is unlocked (click to see how to unlock bootloader on Nexus 6).
- Installing Android 5.0.1 LRX22C factory image will wipe out everything, if the bootloader is not unlocked.
- The Android device should have above 80% battery charge. The device could face a power issue during the process due to lack of battery, which can damage the device.
- The Android 5.0.1 factory images are compatible with Nexus 4 and Nexus 6 models only. Installing these on any other device could brick the device. Therefore, check the model number of the Nexus device carefully before flashing factory images.
- These are Android 5.0.1 factory images not stock OTA update released by Google.
- IBTimes UK will not be held liable for any damage to the device. Users are advised to proceed at their own risk.
