The Nexus 5 was a smartphone developed by Google and manufactured by LG Electronics. It was released in October 2013 and was part of Google’s Nexus line of devices, which showcased the latest version of Android without any manufacturer modifications.

The Nexus 5 featured a 4.95-inch 1080p display, a Ǫualcomm Snapdragon 800 processor, 2GB of RAM, and was available in 16GB or 32GB storage options. It had an 8-megapixel rear camera and a

1.3-megapixel front camera. The Nexus 5 was known for its affordable price, fast performance, and clean Android experience.

One of the standout features of the Nexus 5 was its quick updates directly from Google, which meant it received the latest Android versions promptly. It was one of the last Nexus devices before Google shifted to the Pixel line of smartphones.

Flashing a Nexus 5 smartphone involves installing or updating the device’s firmware or operating system with a newer version. This process can be done for various reasons, such as fixing software issues, updating to a newer version of the operating system, or customising the device with a different ROM (Read-Only Memory).
