It’s been 2 months now since Sony has pulled the curtains off from its latest flagship Xperia Z1, While Google already announced the Android 4.4 KitKat, it was expected that Xperia Z1 will at least run on Android 4.3 Jelly Bean, perhaps keeping the 4.3 aside, Sony pushed in 4.2.2 and 4.3 update was to roll out soon. Sony has already announced its plan for Android 4.4 KitKat, while still no 4.3 update was available, and finally Sony has rolled out 4.3 update today, chances are that 4.4 KitKat will be following it very soon.
A while ago I updated by Xperia Z1 to Android 4.3 Jelly Bean and thought why not to share with you guys right here. In the following post, I’ve explained the method to installed the latest firmware based on Android 4.3 Jelly Bean with the build number 14.2.A.0.290 on Sony Xperia Z1 C6903. You just got to follow this guide to the letter, but before we begin let’s have a look on what’s new in this update.
- New Xperia Themes
- Camera App enhanced.
- New Ringtones.
- Black Notification Drawer
- New Baseband with improved WiFi.
- Stability and performance improvements.
Pre-requisites and Pre-cautions:
- This method is only for Sony Xperia Z1 C6903. Do not try this on any other device, check your device’s model in Settings > About Device.
- You need to have installed Sony Flashtool, Flashtool drivers, and Sony Drivers. Follow the full Flashtool Guide here.
- Make sure that you’ve backed up all your important media content, contacts, call logs and text messages. This is highly recommended in case you need to wipe your phone during the installation process or something goes wrong.
- Make sure that you enable USB debugging options before connecting your device. In case you can’t find the developer options in settings, then you’ll have to enable them. To do so, open Settings > About device > tap build number for 7 times and you should have enabled the developer options in settings. Now enable USB debugging mode under dev options.
- If you have already rooted your phone, it is highly recommended that you use the Titanium Backup to backup all your data so that in case you have to wipe your phone, you can still restore each and everything.
- Use only OEM data cable to connect your device to your PC in order to prevent any connection issues.
- You do not need root access for flashing this firmware, neither you need a custom recovery.
