The build number for latest Xperia Z3 Dual is 23.1.1.E.0.1. It is currently the latest available firmware for D6633 based on Android 5.0.2 Lollipop. The D6633 23.1.1.E.0.1 update is available via OTA updates. However, there is generally no ETA for when your region will receive the update. Moreover, those who have rooted their devices or unlocked bootloaders (basically the phone is not stock) will not receive the OTA lollipop update.

Those who have not received the Official Android 5.0.2 23.1.1.E.0.1 firmware update for Xperia Z3 Dual D6633, can use this guide to install 23.1.1.E.0.1 ftf on D6633 manually using flashtool. This is a simple guide which explains the method to install official Sony firmware on Xperia Z3 Dual. Moreover, flashing will wipe root access and take the phone back to stock state. The only thing that will remain unchanged, is the bootloader. If the bootloader is unlocked, then the phone will stay unlocked even after flashing. The 23.1.1.E.0.1 firmware can be flashed on both rooted and non-rooted Xperia Z3 Dual D6633. The steps involved in the flashing are described below. Make sure that you follow all the steps given below to install the latest firmware on your device.

Early Preparations:

1. This is only for Sony Xperia Z3 Dual D6633

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.
