Sony Xperia Z has started receiving official KitKat update. The latest update’s build number is 10.5.A.0.230 and it is based on Android 4.4.2 KitKat. The other devices receiving KitKat currently are Xperia ZL and Tablet Z. It is based on Android 4.4.2 KitKat OS. The latest update brings a lot of user interface and performance tweaks. The status bar is now transparent and the lockscreen has been changed. It looks more like Xperia Z2 and Z1 now. The RAM managememt is quite better with this update.
If you had rooted previous firmware, then you must have lost root access as well. Thanks to Doomlord, root is now availablefor Xperia Z KitKat firmware. To root Xperia Z C6602, C6603 and C6616 KitKat 10.5.A.0.230 firmware, you will have to install Doomlord Advanced Stock Kernel and then flash SuperSU. To do so, follow the tutorial given below.

Requirements For Rooting

  • Xperia Z
  • Android 4.4.2 KitKat 10.5.A.0.230firmware – Get Here
  • Unlocked Bootloader
  • Working fastboot (Windows 7 is preferrable and get USB drivers below)
This rooting method will installclockworkmod recovery as well. The CWM 6 included in this is quite fast and stable recovery. It is CWM 6.0.4.6 version. This recovery also supports internal storage. Therefore you can flash zip files after putting them in the internal storage. It can also make a Nandroid Backup in internal storage.


Requirements

1. ADB and Fastboot Drivers:

ADB is basic tool for any Android related operation and fastboot is one of its applications. ADB installs all the necessary ADB drivers for Android powered devices and activate the developer mode on device. Various tools require ADB and other components to be installed on the PC for proper functioning. Fastboot is used to issue various commands like for flashing a recovery or a kernel. It is also used in commands related to bootloader unlocking. You can use any of the two tools listed below for ADB and Fastboot commands. First one is a full custom guide, and requires heavy installation while Minimal ADB and Fastboot Installer require a mere ~2MB install. However, the first one is more stable and long-lasting. Choose the one suitable for you.

2.Sony Xperia Z USB Drivers:

Sometimes, you might get the error, waiting for device or similar errors while issuing commands or using any tool. This is mainly due to faulty connection. If you have properly connected your phone with your pC, via a healthy cable and phone is being charged but not being recognized, then the problem is USB drivers. When a phone is connected, PC searched for drivers online and also on PC. You can install USB driversbeforehand and when you’ll connect PC with phone, it will install all the USB driversautomatically. Download Flashtool from the following page, install it, navigate to its installation folder and locate the drivers folder. Install drivers specific for Xperia Zl, including fastboot and flashmode drivers. Make sure that PC installs all these drivers when you connect it.

3.Battery must be charged over 50%:

This is one pf the most important precautions and requirements. You must be aware of the fact that most OTA updates can be installed only if battery is charged more than 50%. This is for the safety of device. The device must not turn off during the whole process. Since these are custom methods, phone may enter a bootloop or may plunge into some other problem. Lowbattery can be a critical issue in these cases. Therefore, you must charge your phone above 50%.

4.Check your Phone Model:

Many times I have seen people bricking their devices because of their negligence. Note that there are several model numbers, with prominent changes for almost every device out there. Therefore, you must confirm that the given guide is for your device’s model number. As an additional precaution, you must also check that the guide is for your phone’s Android version. This is not necessary in all cases. You can check model number and Android version by navigating to Settings > About Phone.

5.Do not turn off Computer during Updating Process:

If either your phone or PC goes down in the mid of process, you might end up bricking up your precious device. Therefore, make sure that your PC will not turn off or restart during the process. If you are using Windows, make sure that there are no pending updates to be installed in, for example ten minutes. PC will restartautomatically, disturbing everything. Therefore, make sure that your PC will remain turned on during the whole process.
Also note that devices are not bricked in every case. It is very rare indeed. however, we must always choose the safe path.

6.Backup all your important Data:

Most custom methods will wipe all dat stored on the device. Some methods might not do so but a custom method can makeyour phone end up in a bootloop and then a factory reset will be essential. Therefore, always make a backup of your device before anything custom. Here is a guide for non-rooted phones, which guides your through all steps to back up a non-rooted device.
You must backup all media files stored in internal storage. As a safe precaution, you might remove SD Card while doing it, however it has never caused anyone any kind of issue. All deleted applications can be installed from Play Store My Apps tab.
If your device is rooted then you have better options for making a backup of your device. You can backup each and every settings along with all applications and all system files along with it. It is pretty useful for restoring your phone to previous state without much hustle. Here is the recommended guide for rooted users.

6.Use correct commands for your smartphone:

You must pay close attention to all the commands described here. You must follow them closely in order to avoid anything unplanned and unpleasant, for that matter. Therefore, always confirm before executing a command.

7.Enable USB Debugging:

Developer Options are, as the name indicates, for development purposes. They are available in all Android devices. The most used and talked about option is USB Debugging. It allows your phone to be handled by PC. You can execute direct commands to your phone via PC. Here isthe list of ADB commands, which can be used with USB Debugging enabled. You can also recover data using ADB commands. Here is complete guide.
To enable USB Debugging, navigate to Settings > Developer Options and enable USB Debugging. Note that in Android 4.2.x and higher, developers options are hidden by default. To unlock these, navigate to Settings > About Phone and locate the build number. Tap is 7 times and you will see a pop up message saying “You are now a developer”.
After enabling Developer Options, you will have to connect to PC and then enable the connection. It is specific for KitKat devices.

8.Backup TA Partition:

TA Partiton contains very important DRM Keys. Losing TA partition also means that BE2 will not work in Album app on Xperia Z. Warranty cannot be gained back by re-locking the bootloader, without TA partition. To make a backup of TA partition,bootloader must never be unlocked andyour phone be running Android 4.2.2 Jelly Bean. You can check the folllowing method of making a backup of TA partition.
