Aptly named 'Optimus G3 ROM' brings flat UI to the LG G2, 4K recording too

A new custom ROM dubbed "Optimus G3" has arrived for the LG G2, bringing the G3's flat interface, 4K recording and more.
June 23, 2014

The arrival of a next-gen handset isn’t just good news for fans of the brand looking for a new phone. Often times, many of the new handset’s features end up trickling down to its older brother either through official software updates or thanks to the efforts of the Android modding community.

For the LG G2, it seems that the ROM community has in fact came to the rescue, with developer OptimusRS bringing the aptly named “Optimus G3 ROM” to the G2. The ROM was ported from the official Korean LG G3 F400K and is based on the LG D802 20d firmware.

The new ROM essentially brings the cleaner, less colorful UI of the G3 over to last year’s LG flagship. In addition to the new UI, there’s also support for 4K video recording, Magic Focus, and a number of other improvements originally meant for the G3. As to be expected, there are a few minor bugs but overall the experience is very stable and more than capable of being your daily driver.

Installation of the ROM seems pretty straightforward, at least for those comfortable with this sort of thing. Basically you need to have your device rooted, custom recovery installed, an you need to do a full wipe before installing. For those that haven’t already, you’ll also need to flash the KK Baseband.

For those looking for more details, you can get full instructions and grab the ROM over at the XDA forum. Keep in mind things can and do sometimes go wrong when installing custom ROMs, so proceed at your own risk.
