For users who haven’t got this update yet, we have written down this guide which will help you to update your beloved Sony Xperia Z C6906 to the latest Android 5.0.2 Lollipop 14.5.A.0.242 firmware. We will do this by flashing an FTF file using Sony Flashtool. Let’s go through some early preps and install the latest version of Android on your device now.

Early Preparations:

1. This is only for Sony Xperia Z1 C6906

This ROM 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.

  • Backup SMS Messages
  • Backup Call Logs
  • Backup Contacts
  • Backup Media – Copy your files manually to your PC or Laptop.
  • Titanium Backup – If already rooted, use Titanium Backup to backup all of your apps, system data and other important content. If you haven’t rooted your device previously, skip this step.
  • Backup Nandroid – If CWM  or TWRP installed previously, otherwise skip this step and perform this at the end of flashing.

4. Enable USB Debugging Mode on your device.

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.

5. Install and setup Sony Flashtool.

You must have installed Sony Flashtool. Find the full guide here.

After installing Sony Flashtool, open the Flashtool folder from the drive where you installed it. Now open Flashtool>Drivers>Flashtool-drivers.exe and install the Flashtool, Fastboot & Xperia Z1 drivers from the list. [Important]

6. Use OEM data cable to establish connection.

Make sure that you use the phone’s original data cable to establish connection between your phone and the PC. Using a different data cable might result in interrupting the firmware installation.
