Android 4.3 Jelly Bean Firmware Leaked for Google Nexus 4, Official OTA Update to be released on July 24th

Android 4.3 Jelly Bean JWR66N firmware leaked for Nexus 4

It seems like the Android 4.3 Jelly Bean AOSP variant has been leaked for the Google Nexus 4 smartphones. It is basically a TWRP Backup file that has been dumped on XDA forums with the build number JWR66N. At the moment, we don’t know if this will be the final variant of the new Android OS, but all things point to that.

This is a TWRP Backup of the Android 4.3 Jelly Bean JWR66N firmware, a file that has been extracted from a phone bought from Craiglist. Also, the device might have belonged to a Google employee. We don’t advise you to install it, but you can still give it a try. Also, installing the update will require you to have a rooted device with the TWRP Recovery installed on it. Use the Custom Recovery Mode and restore the file as you would do with any other ROM backup file, which I’m sure you know how to do that.

Bugs are to be expected, but we cannot confirm if there are any major ones. At the moment, the bootloader and the radio aren’t packed within the file but we should be able to get them in the next few days.

Since this Android 4.3 JWR66N Jelly Bean build has been leaked, we can expect the full release of the OTA Update for Nexus 4 to happen soon. Until then, download the file from here, place it on your Nexus 4 SD card and then boot into TWRP Recovery and use the ‘restore’ option to install. If you don’t know how to grab and flash this TWRP Backup of Android 4.3, then you should return to this post in the hour, as we will post a full working tutorial which will guide you through the process. Check for the link at the end of this post.

Some of the main new features of this OS are as following: Bluetooth Smart (BT 4.0 LTE) is now enabled, the AVRCP 1.3 is ON, new camera software, new gallery, Google Play store v4.2.3 update, Google Keep is now implemented as a system app, better WiFi firmware and tons of other small things that you will notice only after testing the new update.

Next week, July 24, Google will hold an event where it is expected the announcement of the Official Android 4.3 Jelly Bean. The update should be pushed out via OTA for all Nexus 4 phones starting with the next day.
