Install Official Android 4.3 10.4.B.0.569 Firmware on Xperia Z C6602

Sony recently updated it’s Xperia Z lineup to Android 4.3 as it promised. The new update packed up performance enhancements, bug fixes and atop of these Sony changed the Camera UI of Xperia Z to that of the Xperia Z1 and some other minor changes were seen as well. Earlier, we posted methods and firmware links for Xperia Z C6603 and postponed the update’s post for C6602 on our site as there was no firmware available for the device specifically. I managed to get my hands on the official firmware for Xperia Z C6602, download it and then upload on a faster server in order to make it easier for you guys. So, in the following post I’ve embed the firmware download link and also explained how to install this Android 4.3 Jelly Bean 10.4.B.0.569 firmware on your Sony Xperia Z C6602.

Before you move forward, I highly recommend you to check the OTA update or check it through Sony PC Companion and try updating your device. In case you are unable to update through both these, you may head towards the method I explained below and install the firmware manually on your Xperia C6602.

 

Here are some important instructions and  pre-requisites:

1. This guide is only for Sony Xperia Z C6602. Please check your device model first in Settings > About Device > Model.

3. Your phone’s battery must be charged at least over 60%. This is highly recommended in order to prevent any power issues during the process.
4. Make sure that you backup your media content,contacts, call logs and text messages.  This is important and recommended so that in case you decide to wipe your phone during the flashing process, you can get all of your data back using the backup.
5. 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.
6. To flash this firmware, you do not need to root your device, you do not need to unlock the bootloader. All you need is, your device must be the one mentioned and must be running on Android 4.2.2 Jelly Bean or Android 4.1.2 Jelly Bean.
7. Download the firmware file properly.
8. Use the OEM data cable to connect your phone to your PC. Using any other data cable might cause connection problems.
