Install Carbon Android 4.3 custom ROM Nightly for Sprint Samsung Galaxy Nexus

Carbon AOSP team has launched the Nighlties builds based on Android 4.3 Jelly Bean for the Sprint Samsung Galaxy Nexus device. You can use this post in order to learn how to successfully flash all files easily in under ten minutes. Note that this guide is for users who want to tinker with their device and test one of the popular custom ROMs.

The Carbon Android 4.3 Nightly ROM compiles features from Android 4.3 AOSP, CyanogenMod 10.2, ParanoidAndroid and AOKP ROMs. More info about this new Carbon build can be found here and here. If you want to complete the installation at your first attempt, then you should take a look at the preparation guide first. Here’s what you need to know:

  • This guide works only with the Sprint Galaxy Nexus. Don’t attempt to update any other Galaxy Nexus variants with the files you find in this post.
  • Your Galaxy Nexus Sprint model has to be rooted, on an unlocked bootloader and running a custom Recovery such as CWM or TWRP.
  • Without these requirements you cannot flash any new custom ROMs.
  • In the ‘how-to’ part of this post you will find the Factory Reset step. This has to be applied so that the new ROM will boot correctly.
  • Factory Reset wipes data from System partition, while the Internal SDcard files will be left unchanged.
  • Backup data from installed applications using one of these two apps for Android: Helium (here) or Titanium Backup (here).
    – note that the Titanium Backup might not work with Carbon ROMs after the first boot, so you should try and use Helium.
  • Backup data such as SMS text messages, APN Internet Settings or Call Logs info with these apps for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access has to be accepted for some of them.
  • Sync Contacts data with your default Gmail profile.
    – if you don’t know how to do this, then this guide here will help you.
  • Create a NANDROID Backup for the ROM that is currently installed on your device. This will come in handy in case the new custom ROM shows errors or it doesn’t boot in normal mode. This step can be found in the tutorial too.
  • Enable USB Debugging from Developer Options.
  • This is a guide for advanced users, do not blame us in case you brick your device or lose data in the process.
  • Make sure that the Sprint Galaxy Nexus battery has enough charge left, at least 50% is needed, before it completely powers off.
  • If you cannot complete the installation, then you should ask for more help in comments.

Now that you’ve read all of the above, continue to the interesting part of this post.
