Manually Upgrading Nexus 5 to Lollipop (LRX21O)

This is the TL:DR version

I followed this guide

I got my Nexus 5 OTA update for the Telstra version (KTU84Q to LRX21O) from

If you don’t get the KTU84Q to LRX21O version it won’t work.

As windows driver discovery is just rubbish, I manually installed the Nexus 5 windows 7 USB driver (from device manager –> update driver) which was downloaded from

I then had to reinstall the USB driver when the device went into bootloader mode. The device changes its USB hardware ID when it is in bootloader mode. the following fixed it for me.
