Sony Xperia SP, arguably little brother of Sony Xperia Z, is one of the most price friendly phones i have ever used. I called it little brother of Xperia Z because it was released right after Xperia Z was released and shared many properties with its older brother. This phone was launched with Android 4.1.2 Jelly Bean on board. It should be called an “economical performance beast”. Because of an advanced processor, 1 GB of RAM and 4.5 inches HD 720p display, this phone is a little beyond mid-range boundary. However, with catchy low price, Sony has made many new customers.

Gaming on Xperia SP is flawless. The best thing about this phone is low battery drain. I would play 3D games for hours with very low battery drain as compared to other high-end smartphones, thanks to their Full HD and power hungry displays. The only downside to this smartphone is its weight. It feels quite bulky in hand. I don’t know why Sony did it, but it surely is a major con of device. Sony has confirmed Android 4.3 update for the device, however it is not yet spotted in any leaked firmware. But we are sure that this device will even receive Android 4.4 KitKat update because of its amazing hardware.

This guide is for Sony Xperia SP C5302/C5303 12.0.A.2.254 firmware only!

Root means to gain control of Phone’s system files, which are unreachable in a unrooted phone. Well what is its advantage then? With access to system files, you can modify your phone’s UI, apps or appearance in any way you want. You can install Beats Audio drivers, Samsung’s touchwiz or HTC’s Sense. You can also install custom ROMs. Custom ROMs are software developed for a specific smartphone. It is developed by free lancer developers. Custom ROMs are built to obtain certain goals. One of these goals can be to remove bloatware and install Stock Android on your smartphone. Stock Android is free from manufacturer specific apps and as far as i have seen, it much much faster an simple to use. Another very interesting use of root is to use certain root apps. You can download Root apps from play Store. With apps like Titanium Backup you can backup not only just apks of apps but also their data.

    Hello M.Aswad mehtab. No, after rooting or unlocking bootloader, you will not be able to install OTA updates, however you will receive notifications. You can install OTA update by unrooting your device or relocking bootloader in case you have unlocked it.

    can i install custom rom without unlock bootloader?

    • http://techglen.com/ Hayder Ameen

      Most of the custom ROMs require unlocked bootloader. Few can be installed with locked bootloader but they are only stock based ROMs.
