Root Xperia Z C6602,C6603 10.6.A.0.454 5.0.2 LP Plus CWM/TWRP

Sony Xperia Z has started receiving the Android 5.0.2 Lollipop update with build number 10.6.A.0.454. The update is being rolled out for both C6602 and C6603. One is 3G only model while other is 3G+4G Model. The basic and most probably the only difference between both phones is the bands that these phones support. Those who have not received the OTA Lollipop update yet can update their devices using manual Update Xperia Z To Lollipop Official Firmware Guide. After updating, Android power users will lose root access. Keeping phone in stock state is something power users would never do.

To root Xperia Z Lollipop update, there is not simple method available yet. 10.6.A.0.454 root can be done using the pre-rooted firmware.

This rooting method 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 firmware 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. 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.

Enable USB debugging mode on your device. To do so, tap settings>developer options>USB debugging. If you can’t find developer options in settings, then tap settings > about device and tap “Build Number” for 7 times and you’ll get em’ activated under settings.
