Install Android 7.1 Nougat on LG Optimus L90 via CyanogenMod 14.1 Custom ROM


LG Optimus L90 is a pretty old device. LG released this phone back in February, 2014. Optimus L90 carried a 4.7 inch display with 540 x 960 pixels at 234 ppi. It was powered up with Qualcomm Snapdargon 400 CPU alongside the Adreno 305 GPU. A RAM of 1 GB was present inside and the phone had an 8 MP shooter at the back while a VGA shooter on the front. This phone ran on Android 4.4.2 KitKat out of the box and that was the only firmware to which this device sticked. The only software updates that the L90 has been getting are the custom ROMs. LG itself hasn’t given any attention to a greater piece of software for this phone. We were lucky enough to have the Android Lollipop and Marshmallow based on custom ROMs for the L90. Since Android Nougat is also out now, it’s the time to flash that and give this phone another new life.install-android-7-1-nougat-on-lg-optimus-l90-via-cyanogenmod-14-1-custom-rom

So, it’s time to take out your L90 out of the drawer and wipe off the dust from it in case you haven’t used it for a while. The Android Nougat update for the L90 is based on the popular and the mostly widely used custom ROM CyanogenMod 14.1. At the time of writing this post, the features like Phone, Data, SMS, Audio, Video, WiFi and Bluetooth are working fine on this phone. The only feature that’s found to be crashing is the camera, but we hope it to get fixed soon as well. It may carry a few more bugs, but you should be able to tackle them if you have had a slight experience of flashing custom ROMs in the past.

We will just cut it short and get back to the point now. The following post will teach you on how to install Android 7.1 Nougat on LG Optimus L90 via CyanogenMod 14.1 custom ROM. You will need a custom recovery and a few steps to get done with it. Let’s go through the early preparations and flash the ROM now in order to be able to enjoy Android 7.1 Nougat on the LG Optimus L90.
