Starting from now, the Sony Xperia Arc users will be able to enjoy the Android 4.1.1 Jelly Bean experience as a new custom ROM firmware has just been leaked. The same can be applied on the Arc, but only by following the present step by step guide. The ROM is dubbed as Paranoid and it is coming with the latest Jelly Bean features and Google apps available for updating and improving your Xperia Arc handset. This how to procedure will be compatible only with the already mentioned device so don’t try to complete it for similar Android based smartphones.
The update was developed and first tested on the Arc by those of xda-developers, so we have them to thanks for this opportunity. As you may know there are no words about a future Jelly Bean OS suitable for this phone therefore if you want to receive and test the latest Android system, then this is the perfect opportunity for you. This means that this is not an official firmware released by Sony and it cannot be OTA installed. You will have to follow and complete a manual procedure which will take you through the installation operation. The guide is easy to follow and the steps easy to understand so you have nothing to worry about. Just read all the next lines for ensuring that your phone is in safe hands.
First of all, and before starting the proper tutorial, you must prepare your Xperia Arc for the update process. You will not be able to flash the Paranoid Jelly Bean 4.1.1 ROM on it unless you previously root the system. We are dealing with a beta software, so the root access must be granted. This implies in unchaining the Android system and in removing the factory restrictions which leads only to one thing: by rooting the Arc you will void the warranty. Be careful in what you do and always follow a step by step guide like the present one, don’t perform things by yourselves. The warranty can be restored but only by downgrading to the stock ROM, or by updating to an official update released by Sony and suitable with your Xperia Arc. After rooting the phone you must install a custom recovery image into the system, so take care of this too. In the end you can return here and resume the rest of the pre requisites.
Also, as you will see during the steps from below, a wipe of the system must be performed if you want to properly install the Paranoid Jelly Bean custom ROM on your Xperia Arc. Unfortunately, this operation will make you lose all of your personal info and data which is stored on your phone’s internal storage memory (the SD card will not be affected). The best way for preventing this is by making a backup operation first. This should be completed even before the root one, so let’s say that it should be the first thing to take care of. The backup task in not hard to handle as there are many ways in which you can save your data: you can use a computer, an SD card and several apps available for free from Google Play. You have some tips and how to guides below along with other pre requisites, so go and check them out.
- Backup the text messages by downloading and installing SMS backup and restore apps for Android.
- Save call logs by downloading suitable backup and restore apps.
- If you want to save the contacts, then learn how to sync with your Google account.
