Update Galaxy Nexus GT-i9250 to Android 4.2.1 Jelly Bean (KALO ROM)

After almost every fan of Samsung finished squealing about the company’s new Galaxy Nexus GT-i9250, a problem began to arise. Namely: this smartphone didn’t allow for a Jelly Bean 4.2.1 update.

But a developer quickly thought of a solution to the issue at hand. He created a new custom ROM which could very easily grab this operating system for your handset.

The name of this ROM is KALO. However, be aware that it is not an official tool, but it works wonders and it doesn’t drown your phone in bugs or such.

Requirements

We haven’t forgotten about the usual set of requirements, though. So here they are: turn off all of the antivirus software you have on your smartphone, make a backup, fully charge the device’s battery, root the phone and install on it a custom recovery ROM, activate the USB Debugging and check if its bootloader is unlocked on board the Galaxy Nexus GT-i9250. The warranty of this particular model is going to disappear after the upgrade, but if you get official Samsung software for it, it will eventually come back.Galaxy-Nexus-I9250

And now for the steps which are going to get your Google Nexus GT-i9250 updated to Android 4.2.1 Jelly Bean via the KALO custom ROM.
