Android 4.3 Jelly Bean has been officially announced and released yesterday. Now, some developers have already begun to work on releasing custom ROM based on it. Use this tutorial to learn how to flash the custom Android 4.3 JB OTA-like ROM for your Verizon Samsung Galaxy Nexus.
If you plan on installing this ROM on your device, then you will first need to take a look at the preparation guide below:
- use this post only with the Verizon variant of the Samsung Galaxy Nexus.
- do not attempt to update any other Android device using the files you find here.
- your phone has to be rooted and running a custom Recovery image such as TWRP or CWM.
- this post contains instructions on how you can flash the new ROM using both TWRP and CWM Recovery mode.
- before installing the new ROM, use the Custom Recovery Mode and create a full NANDROID backup of your currently installed ROM. This file will act as a backup file and it can be used in case something goes wrong such the device getting bricked or the new OS doesn’t boot into normal mode.
- in the how-to part of this post you will find a step that asks you to wipe data and factory reset your device, confirm that process.
- factory reset will remove all contents from your device’s /system partition, all installed apps and other similar data will be removed in the process.
- use an app from Google Play Store to backup installed app data.
- if you want to backup SMS, Call Logs info or APN Internet Settings, then you should use the following applications: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access will have to be granted for some of these apps.
- sync your Contacts with your Gmail account. If you don’t know how to do it, then you can choose to follow the instructions listed here.
- enable USB Debugging from the Developer Options menu.
- make sure that the phone’s battery has enough power left before switching off. In case the phone powers off in the middle of the updating process, you will be forced to repeat the entire tutorial once again.
- this guide is mostly destined to be used by advanced users.
- don’t blame us in case you brick your phone or you lose any important data.
- make sure to read the entire post, don’t skip any steps and ask for more help in comments if you cannot complete the installation.
