Update Galaxy Nexus I9250 to 4.1 Jelly Bean with EaglesBlood Custom ROM Firmware

Even though there are several custom ROMs available for the Samsung Galaxy Nexus I9250 handsets, we can say that there’s never enough. And that’s not only our opinion as those of xda-developers had just pushed out another Jelly Bean based firmware, the EaglesBlood one. So, today we will be checking in how to update your Galaxy Nexus to EaglesBlood Android 4.1 platform by following an easy to understand step by step guide from where you can learn everything about the mentioned operation. We will see which are the benefits that come with such an update, the pre requisites and finally the basic installation procedure, so let’s get started.

First of all, the present update has been made by third party devs, so it has nothing to do with Samsung. It is just a custom ROM based on the latest version of the Android OS, being designed to offer features and capabilities that cannot be found in the official version of the Android platform. Furthermore, by flashing the EaglesBlood software on your Nexus I9250 you will be able to improve your phone’s performances by customizing the system and of course by adding important features. In a few words, the OS will be optimized so that you can obtain more power and speed from your smartphone, the battery life will be upgraded, the looks changed (the classic Android looks and appearances will be replaced) and the web browsing experience improved.

These are just some of the ROM’s advantages; I let you discover the rest of them by yourselves. The most relevant aspect it saying that the EaglesBlood firmware is being the most stable one available for the Galaxy Nexus, so there shouldn’t be bugs or things that aren’t working in the system. But for being able to enjoy all these, you need to prepare some things. The first to start with is the root access. Unfortunately, you can’t apply this tutorial on a locked smartphone. This means that you need to remove the factory restrictions first. The root procedure is what you need, so go and take care of the same. You can then return here and resume the rest of the guide.

After rooting your Nexus, you must install a custom recovery image, like CWM, into its system. You need to do this because the update can’t be applied unless you flash the ROM file from your handset and this can be done by using the mentioned recovery tool. Also, the recovery can be used for other operations too, like backing up the current ROM (as you will see it’s more than indicated to do this task) or wiping the data out. As soon as you root and install the CWM tool you can start the update process which is explained below.

But, before you do so maybe it will be a good idea to backup the data from your Galaxy Nexus. I have mentioned something about a wipe before, so as you can tell, during the flashing operation, your personal info will be wiped out; so for preventing from losing your data just backup it. It will be a good idea to backup the current ROM too as at this point the warranty will be void and if you somehow damage the new OS you can restore the old one without any problems. The warranty will be lost as soon as you start to root the system. This is happening because you are removing the factory restrictions; don’t worry though as you can restore the warranty as soon as you downgrade to the stock ROM or if you update to an official update released by Samsung and suitable for your Nexus.

Now, the backup can be easily performed. But along with this you must take care of other preparation processes too. I have mentioned all you need to know in the list from below, so check and complete the same. Don’t skip this part as you might regret it afterwards.

  • Learn how to use CWM for backing up the current ROM.
  • Learn how to backup the text messages by downloading backup and restore apps.
  • Learn how to save the call logs by downloading backup and restore tools for Android.
  • Learn how to save contacts by syncing with your Gmail account.
  • Use a computer or SD card for saving any other file.
  • You will have to use a Widows running computer for the update process.
  • On the computer and on your Nexus uninstall the security tools (antivirus, etc.).
  • Then, on your phone enable the USB debugging option.
  • And charge its battery or ensure that it has at least 60% power left.

This operation is considered risky so be careful in what you do and don’t hurry up in completing the steps. The present guide is being suitable only for the Samsung Galaxy Nexus model number I9250, so don’t try to apply it for a similar device as you can brick it. Don’t forget to root and install a custom recovery image on your phone first.
