Android Lollipop brings many
visual improvements, such as a new Quick Settings
panel, a card-based notification system, and so on, but most of the significant changes, such as the new 64-bit guts, are actually under the hood. If you are too impatient for waiting the OTA update to hit your trusty Nexus gear, here's what you need to do to sideload the Lollipop firmware:
panel, a card-based notification system, and so on, but most of the significant changes, such as the new 64-bit guts, are actually under the hood. If you are too impatient for waiting the OTA update to hit your trusty Nexus gear, here's what you need to do to sideload the Lollipop firmware:
1. Download the Android SDK,
disguised as Eclipse ADT Bundle from Google. This is the software that
makes communication between your computer and your Android device
possible;
2. Download the respective Android 5.0 Lollipop factory image for your Nexus 5, Nexus 7, or Nexus 10 device;
3.
Run the SDK manager, check Google's USB drivers, and uncheck everything
under Android 5.0 as you won't be needing emulators. The "Android SDK
Tools" and "Android SDK Platform-tools" checks can be left for updating
to the newest editions;
4. Back up the stuff
you need on your Nexus gear, and put your device in Fastboot mode by
turning it off, and then holding volume down+power (or volume up + down +
power on some devices);
5. Unzip your factory
image and put its contents in the "Platform Tools" directory of the SDK
that you installed, so that the "flash all" files end up in the same
folder that contains the file "fastboot."
6.
Connect your phone or tablet to the computer, while it is sitting in the
Fastboot screen, and see if at the bottom, at the LOCK STATE line, it
says "locked" or "unlocked". If it says "locked", we will need to unlock
the bootloader, so that we can install the Lollipop factory firmware.
Choose the "fastboot oem unlock" option, and pick "yes"on the next
screen by navigating with the volume key, and choosing with the power
button. Bear in mind that this will wipe all your data;
7.
If the phone booted in the welcome screen, restart it in Fastboot mode
again, then using the command line, navigate to the respective Android
SDK/platform-tools folder, then type: flash-all.bat for the flashing
tool to start updating your Nexus to the newest Android 5.0 Lollipop.
Now you just need to wait a looong time, then your device will be
brought kicking and screaming to the newest Android version.
