Update Your Sony Xperia Z1 (C6902 & C6903) To Firmware Version 14.1.G.2.257 Manually
Sony Xperia Z1 is a great phone, at least on paper. But in a rush to release the device to the market ahead of the Apple iPhone 5S and iPhone 5C, Sony shipped the Xperia Z1 with less than stellar firmware version. The camera although had a great hardware, took some hit and miss shots sometimes. Also the battery life was not as great as it should have been.
Now Sony has just released a major update to the Xperia Z1 C6903 (LTE) and Xperia Z1 C6902 (Global HSPA+). Although the Android version is retained to v4.2.2 JellyBean but the firmware is said to be build from scratch (just the rumours, can't confirm). There are improvements to the camera, which now takes images with much less noise. There are improvements to display, fonts and battery life as well as some other bug fixes.
If you own an LTE C6903 Xperia Z1 handset, chances are that you are already getting the OTA update. But the owners of Sony Xperia Z1 C6902 (Global HSPA+) still didn't get the OTA update, it could be days before the OTA update starts rolling to your respective countries. Can't wait till then? Here's how to update your Xperia Z1 manually.
Backup your phone contents completely.
Download the Sony Xperia Z1 14.1.G.2.257 Firmware FTF files (C6902 & C6903) from the given links.
Download the Sony Xperia Flash Tool from here.
Paste the Update FTF File that you've downloaded to the folder named as "Firmware“ included in the Xperia FlashTool
Now open the FlashTool and click on "Flash" & choose the downloaded firmware file.
Click OK and turn off the Xperia Z1.
Now the FlashTool shows the pop up window. You can now connect your Xperia Z1 to your PC. Remember to hold the VOLUME DOWN button while connecting phone to PC.
This process takes a few minutes. Make sure that the USB is not disconnected while this operation is going on.
After the flashing process is completed, the FlashTool displays the message to unplug the device and restart.
Voila! Your Sony Xperia Z1 is updated to the latest version (14.1.G.2.257)
