Xperia Z1 Compact Sony

Last week Sony released a stock firmware update with build 14.5.A.0.270 based on Android 5.0.2 Lollipop for Xperia Z1 Compact and other Xperia Z1 series. Along with a bunch of fixes, Sony has added the close-all buttons in the activity menu.

The OTA should now be available for all regions. Besides, there are FTF files to manually update the phone using the flash tool.

Installing the stock update removes the root from your phone. If you want to gain root after the update, you will have to go through the entire process all over again. You might be looking out for stock firmware, which is pre-rooted.

Here is good news. XDA forum member Mirhawk, has posted a flashable zip for the stock Android 5.0.2 14.5.A.0.270, which is rooted with SuperSU v2.46 and even has locked dual recovery installed. The firmware used here is an Indian generic.

So, if you just have a custom recovery on your Z1 Compact, installing the pre-rooted stock firmware will not be troublesome for you.

Check out the following installation guide if you want to manually install the pre-rooted official update on your phone.

Note that you need the Z1 Compact D5503 international model. Do not forget to keep a backup of all data of your phone.
