In case of being the owner of a Sony Xperia SP smartphone, you probably know that the company decided to stop updating it to the most recent Android OS versions. Don’t take it personal; this is something that it usually happens with those devices that aren’t exactly new, but I can assure you of the fact that there is someone thinking of you as well.
The unofficial built of Android 6.0 Marshmallow CM 13 has been made available by xda-developers and yes, it is indeed based on the latest AOSP Android 6.0 M pure software. In such conditions, you know that this is literally your only chance to enjoy a change on your Xperia Sp, but I want you to know a few things about this version and procedure from the start.
First of all, let me be clear about the fact that the CM13 Android 6.0 Marshmallow ROM is still under alpha stage of development, so there are big chances to come with a few untested bugs and broken features. Even more, you are going to lose any warranty that might be left on your Sony Xperia Sp as long as you are using an unofficial port of stock Android 6.0 M OS and that’s not all.
In that matter, you also need a custom recovery image of your choice and along with it, you will have to gain root access on your Sony Xperia SP. Without root you cannot install the CM 13 Custom ROM firmware, thus without root there is no way to run Android 6.0 Marshmallow on your phone.
If all these are not a problem, go on with the preparation of your computer / PC or laptop. To be more specific, verify that the correct USB drivers for the phone are installed there and temporally deactivate the antivirus which usually slows down or stops such operations from following their regular course.
Then, save everything that you want to keep using after the CM 13 update procedure ends; I know that the lists is long as I am talking about your precious contacts, texts, images, call logs, videos, audio files, IMEI / NVRAM data, apps, internet settings and so on, but this is for your own good, so take your time and be responsible.
You must also gain developer options on your Sony Xperia Sp. For that, you just have to tap several times on built number under Menu – Settings – About phone in order to check the USB debugging option which can be found on Menu – Settings – Developer options. And if your battery status shows any value less than 50% power left, plug in the charger and have patience as your phone might get bricked if it gets turned off during the flashing process.
How to Install CM13 ROM on your Sony Xperia SP:
- On your computer, take the Android 6.0 M package from here;
