Sony updates Xperia Z and Xperia ZL, improves performance
A month back on June 24, Xperia Z was officially update to Android 4.2.2 Jelly Bean 10.3.A.0.423 firmware and some days back we saw another Jelly Bean 10.3.1.A.0.236 firmware OTA update being rolled on Xperia Z but only on developer handsets, which was a lot curious why such a firmware was rolled and users reporting it were very few.
But now, in INDIA region, we have just spotted another 10.3.1.A.0.244 firmware on our Xperia Z C6602 HSPA+ version via PC Companion as well as via SUS. No such update is seen listed on PTCRB site also. Update also confirmed on Xperia Z C6603 LTE version now.
We can confirm that 10.3.1.A.0.244 firmware update for Xperia Z C6602 is just a patch update of Android 4.2.2 Sony must have patched the perf_event exploit. So Root from previous 10.3.A.0.423 firmware will now be lost sadly.Xperia ZR C5503 / C5502 has also been updated to same Android 4.2.2 10.3.1.A.0.244 firmware update, check below link.

Xperia Z C6602 / C6603 Android 4.2.2 10.3.1.A.0.244 firmware update ftf – Manual Updating
[ UPDATE ]XDA Developer DooMLoRD has just tweeted that all Xperia Z / ZL users who have rooted handset, shouldn’t flash this 10.3.1.A.0.244 firmware ftf file directly. They should use OTA ROOT KEEPER, otherwise root will be lost in this new firmware.How to keep Root in Xperia Z, ZL Android 4.2.2 10.3.1.A.0.244 firmware update ?
If you are updating your Xperia Z, ZL directly via Flashtool, everything in (the /system partition) gets formatted completely, so you loose root :/ So update it over OTA to keep root.
Root Access will be lost, if flashing via FlashTool.Use OTA RootKeeper, if you want to have root access remain to your phone. If you are updating your Xperia Z, ZL by “Update Center” app, then using OTA RootKeeper, you can save your root access.
All those who have not got update yet can download the ftf file and install it manually.
