Google had recently released the Android Lollipop 5.1 version along with its changelog, and it has already started to become obsolete, let alone the 5.0 or 5.0.2 versions (they are too old to discuss about now). Recently, Google had released the factory image of 5.10 Lollipop for the Nexus 6. The new build LMY47E, which is different from the previous build, LMY47D.
For the newbies, here is a guide on how to install the factory image of 5.1.0 Lollipop in your Nexus 6:
- First of all, Download the factory image for the new build from here.
To flash a device using one of the system images below (or one of your own), you need the fastboot tool. You can get the fastboot tool either:
-
From a compiled version of the the Android Open Source Project.
-
Or, from the platform-tools/ directory in the Android SDK. Be sure that you have the latest version of the Android SDK Platform-tools from the SDK Manager.
Once you have the fastboot tool, add it to your PATH environment variable (the flash-all script below must be able to find it). Also be certain that you’ve set up USB access for your device, as described in the Using Hardware Devices guide.
Caution: Flashing a new system image deletes all user data. Be certain to first backup any personal data such as photos.
To flash a system image:
-
Download the appropriate system image for your device below, then unzip it to a safe directory.
-
Connect your device to your computer over USB.
-
Start the device in fastboot mode with one of the following methods:
-
Using the adb tool: With the device powered on, execute:
-
adb reboot bootloader
-
Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device. For example, to put a Nexus 5 (“hammerhead”) into fastboot mode, press and hold Volume Up + Volume Down + Power as the device begins booting up.
-
-
If necessary, unlock the device’s bootloader by running:
-
fastboot oem unlock
-
The target device will show you a confirmation screen. (This erases all data on the target device.)
-
Open a terminal and navigate to the unzipped system image directory.
-
Execute the flash-all script. This script installs the necessary bootloader, baseband firmware(s), and operating system.
Once the script finishes, your device reboots. You should now lock the bootloader for security:
-
Start the device in fastboot mode again, as described above.
-
Execute:
-
fastboot oem lock
Locking bootloader will wipe the data on some devices. After locking the bootloader, if you want to flash the device again, you must run fastboot oem unlock again, which will wipe the data.
This update for the Nexus 6 is obviously to fix the memory leak issues, which was experienced in the 5.1 Lollipop for LMY47D build. For rest of the devices running on 5.1 (the Nexus 5, Nexus 10 and Android One devices, which recently got the update) Google has secretly fixed the issue without rolling out any major update, so there is nothing to worry about.
Did you update your Nexus 6 to latest build installing the factory images provided by Google? Feel free to share your experience or opinions in the comment section below.
