Galaxy S5 G900F receives Android 5.0 Lollipop build XXU1BNL2 via official firmware
Update Nexus 4 and Nexus 6 to Android 5.0.1 build LRX22C Lollipop via factory images

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.
