Update Nexus 5 with Pure Android 5.0 Lollipop, Fastboot Flashable Native Lollipop and Illusion ROMs
There is some great news for Nexus 5 owners as third-party custom Android developers have built three variants of Android 5.0 Lollipop ROMs for the device based on Google's recently released AOSP source code.
As all three lollipop ROMs are still in their early testing stages, they may contain some untested bugs or broken features.
Nevertheless, those who wish to try out the various flavours of Lollipop ROMs ahead of Google's official OTA release may go ahead and install the ROMs, using the simple step-by-step guide provided below.
IBTimes UK reminds readers it will not be held liable for any damage to device during or after Android 5.0 Lollipop firmware installation. Users are advised to proceed at their own risk.
Pre-requisites
- The instructions given in this guide are meant for the Nexus 5 only. Verify device model number by navigating to Settings > About Phone.
- Ensure the phone has at at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
- Back up data and settings using a recommended custom recovery tool, like ClockworkMod(CWM) or TWRP, as it creates a complete image of the existing phone setup. In Recovery, choose Backup and Restore and tap Backup.
- Verify correct USB drivers for the phone are installed on the computer (download Google USB drivers).
- Ensure that the device is rooted with TWRP recovery installed and its bootloader is unlocked.
Fastboot Flashable Native Lollipop
This is the first ever Android 5.0 Lollipop ROM available for users, courtesy of XDA recognised developer, OldDroid.
As the ROM is an initial build in its early debugging stage, the developer has not included Gapps and boot animation with the installation package.
The catch here is that you will see that your device may enter a black screen while booting, as there is no boot animation screen included with this firmware.
Downloads Required
Fastboot file: Download
Guide to Install Fastboot Flashable Native Lollipop ROM on Nexus 5

Illusion ROM (Build LRX21M)
The Illusion ROM is the creation of XDA recognised developer herna. It is based on the original AOSP source code for Android 5.0 Lollipop that uses the binaries from early developer preview build for Nexus 5.
There is better news for Nexus 5 users who are planning to install this ROM as it includes the Gapps package within the ROM install files and hence you need not hunt for compatible Gapps package separately.
The ROM comes pre-rooted and hence brings Super-user access out of the box. Consequently, it removes the arduous task of rooting the firmware again.

Steps to Install Android 5.0 Lollipop on Nexus 5 via Illusion ROM
