With Android 4.1 Jelly Bean officially arriving to a number of devices, we’ve been writing non-stop about Jelly Bean-based ROMs for a number phones and tablets. We’re taking a short break from that to bring…
Just recently, the OTA update for Android 4.1.2 Jelly Bean build JZO54K for some of the Nexus devices started rolling out to some regions. Apparently, there are still some owners who have reportedly received nothing and have been tapping on their devices' System Update option in hopes of receiving the update. Some have decided to wait in vain and some have decided to manually upgrade their devices.
Android 4.1.2 build JZO54K provides more than a newer version of Jelly Bean. This update allows users to bid bye-bye to expanding and collapsing notifications with two-finger gestures. With this update, one-finger gestures are enough to expand notifications by tapping and dragging notifications downwards and collapse notifications by tapping and dragging notifications upwards.
If you have with you a Google Nexus S (GT-I9020, GT-I9020T, or GT-I9023) and opted to go for updating your phone manually, you are in luck. Today, you can happily go to bed knowing that your Nexus S had been updated to the latest build.
This update will also restore your phone to stock firmware if you want to revert from a custom ROM. For users of the Sprint variant, the Nexus S 4G SPH-D720, you may have to wait a bit more for developers to release your phone's factory image that will allow you to update your phone to Android 4.1.2.
This guide shows you how to flash stock Android 4.1.2 Jelly Bean build JZO54K for the Nexus S manually. Official Google-provided factory images are used.
