Sony Xperia ZL : Upgrade to CyanogenMod 10.1 Jellybean Firmware

Sony Xperia ZL is the latest addition to the Android smartphone market by Sony. Powered by a RAM of capacity 2GB and an storage of 16GB, Sony Xperia ZL was awaited for a while by Android experts. It works on Quad-core 1.5 GHz Krait processor. The Sony Xperia ZL comes with Android Jellybean 4.1.2 Stock ROM.

While Sony Xperia ZL has great hardware specifications, you cannot make full use of it with the pre-installed ROM. And as per me, there is no profit in buying a high-end Android device if you don’t tweak with it.

Keeping the same in mind, we are here with CyanogenMod 10.1 Jellybean 4.2.2 Firmware upgrade for Sony Xperia ZL.
