Update Sony Xperia SP with CM11 Android 4.4.2 KitKat Custom ROM

Sony Xperia SP is a mid range Android smartphone that comes with decent performances on an affordable price tag. Due to same reasons, this device is quite appreciated and popular along worldwide Android users. Well, because of that, I have decided to show you how to easily improve the performances of your Xperia SP by installing the Android 4.4.2 KitKat based CM11 custom ROM firmware on your smartphone.

As you might know, an unofficial port of CM11 has been previously released for the Xperia SP; the update was buggy and there were a few problems with the OS, but now we have an improved variant of CM11 for your Xperia SP – you can flash the custom ROM for daily use. The update process can be easily applied, though many users had complained about the flashing operation. So, in order to help you out, we have developed the present step by step guide which can be safely and easily applied on the Sony Xperia SP. But for further info about the same, don’t hesitate and read the guidelines from below.

CM11 represents a free aftermarket distribution of Android 4.4.2 KitKat OS that is now available and compatible with your Sony Xperia SP. This is a custom ROM and not an official update, so CM11 has nothing to do with Sony or with Google. In that matter, it should be clear for you that this update operation isn’t official and by completing the same you will lose your Xperia SP warranty – if you have doubts and if you think that you might end up in bricking your device, maybe the best will be to stop going any further.

Anyway, if you follow the guidelines from this tutorial everything will be fine. Furthermore, the warranty can be anytime restored as soon as you choose to update or downgrade your Android smartphone to stock or official Android OS – you will have to apply the Android firmware manually by using Flashtool.

CM11 is one of the most powerful and popular Android 4.4.2 based custom ROM firmware available on the market. The software comes with stock and extra (that cannot be found on the default KitKat platform) features, apps and capabilities that can be used for powering up the performances of your Sony Xperia SP. Moreover, with this custom ROM flashed, you will be able to customize and optimize your device and you will be able to speed it up and to upgrade its battery life.

But, for being able to install Android 4.4.2 KK CM 11 custom ROM on Xperia SP by using this tutorial, first you have to root your SP. Also, after gaining root access you need to flash a custom recovery image on your phone – use the latest version of CWM or TWRP recovery in that matter. Don’t skip these operations as without the same you can’t complete this step by step guide. Be careful as all these procedures aren’t official – use compatible methods that have been already tested on the Xperia SP as you don’t want to end up in bricking your Android device.

Another thing to do before starting the update process is a backup. By using a custom recovery image for flashing a custom ROM, a wipe is being required. So, all of your data from your Sony Xperia SP will be wiped out. Due to same reasons a backup is highly recommended; you should use backup and restore apps for saving your personal data, info and accounts and your contacts, call logs, text messages or market apps. Also, you should use the custom recovery image for saving your current ROM – make a Nandroid backup.

Good; after taking care of your data ensure that you can use a computer, your phone and its USB cable. CM11 will be downloaded on your PC, so a connection between your computer and your Xperia SP will have to be established – enable the USB debugging option on your phone (go to menu – settings – developer options). Also, on your computer you should first disable the antivirus and security protection – only temporarily as these programs might interfere with the download process. Then, you should charge your handset because it might get bricked, in case it gets turned off in the middle of the update operation – do that especially if the battery power shows less than 50% power left. Moreover, complete this guide only if you own the Sony Xperia Sp and no other Android device as the steps from below are compatible only with the same.
