Prolific custom ROM developers, CyanogenMod have released the new Android v4.4.4 KitKat CM11 M8 firmware to Sony's 2013 flagship phone Xperia Z1 model.
CyanogenMod CM11 M8 Custom ROM is based on the ASOP (Android Open Source Project) v4.4.4 KitKat OS and is said to bring customization options to boost device performance, new visual interface, easy access to key apps and lots of other user-experience enhancing features.
Prerequisites (things to remember before installing Custom ROM in to the device):
- Rooting enables users to install custom ROMs or third party apps of their choice and also perform tweaks in the settings to improve the device's performance. Though users get more control over the smartphone this way, it makes the company warranty void and they will no longer be liable to provide future updates [warranty can be restored by flashing the device with stock-ROM].
- This custom firmware (CM11 M8) should be installed only on the Sony Xperia Z1, if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number].
- Installation of custom ROM requires clearing of whole data in the smartphone, so make sure to back up all the data by installing Clockwork Mod (CWM) Recovery/TWRP in your smartphone.
- Users make sure they have installed USB drivers on the PC, or else your smartphone (Sony Xperia Z1) will not be recognized by the computer.
- Make sure your device has more than 80 percent battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted.
[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. TecHGEEks cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.]
