Sony’s Xperia P is a great mid-range device. Although this device is pretty much old now, but is still used by so many users across the world. Xperia P sports a 4.0 inches screen with 275 ppi. Under the hood is a 1.0 GHz dual core CPU accompanied by Mali-400 GPU. There’s a RAM of 1 GB, internal storage is ranged at 16 GB. At the back Sony has placed an 8.0 MP shooter while a VGA shooter on the front, no doubt Sony always produces the best cameras for its smartphones. The only thing this device lacks in, is its software. Xperia P ran on Android Gingerbread out of the box and the device could only get Android 4.1 Jelly Bean as its higher update.

While Google is heading towards Android L, this leaves Xperia P users in a little bit of disappointment having their device on the very old Android 4.1 Jelly Bean firmware. But this should eventually come to an end since there’s a number of great developers coming up lots of custom firmwares for so many Android devices. These custom firmwares definitely give the forgotten devices a new life by letting the users taste higher version of Android unofficially. Similar thing for the Xperia P has been done by XDA senior member percy_g2 who brought the users Android 4.4.4 KitKat based on CyanogenMod 11 custom ROM. 

In case you don’t know about CyanogenMod, CyanogenMod is the most popular and widely used aftermarket Android firmware that is available for so many devices. In the following post we are going to install this Android 4.4.4 KitKat CyanogenMod 11 custom ROM on our beloved Sony Xperia P. Let’s go through the early preparations and begin with the ROM installation.

Early Preparations:

1. This is only for Sony Xperia P!

This custom ROM is only for the device mentioned above. Make sure that your model number matches the one listed above. To do so, go to Settings > About Device on your device and see your model number. Flashing this ROM on any other device will result in bricking it so make sure that you meet this requirement first of all.

2. Battery should be charged at least over 60%.

Make sure that your battery is charged enough to complete the flashing process. In case your battery is low and your device goes dead during the flashing process, you may end up soft bricking your device as it won’t complete the flashing process.

3. Unlock Bootloader.

Your device’s bootloader must be unlocked in order to flash this custom ROM. You can unlock it by using our Sony bootloader unlock  guide.

4. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.

• Backup SMS Messages
• Backup Call Logs
• Backup Contacts
• Backup Media – Copy your files manually to your PC or Laptop.
• Titanium Backup – If already rooted, use Titanium Backup to backup all of your apps, system data and other important content.
• Backup Nandroid – If CWM  or TWRP installed previously, otherwise skip this step and perform this at the end of flashing.

5. Disclaimer

The methods involved in flashing custom recoveries, roms and rooting your phone are highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is Sony in our case.
