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.

10.3.1.A.0.244 firmware update confirmed in India, Sweden, Egypt, Saudi Arabia, Poland till now. Same 10.3.1.A.0.244 firmware update is also confirmed on Xperia ZL C6503.

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 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.

      yes no one has till now has made a mirror for C6602 file, so we posted the links for C6603…You can flash the files for C6603 ( both are same phone except one has LTE ) so when you are done with flashing C6603 file, your phone will say C6603 in about phone which you can also change by editing build.prop after root and your phone will also show LTE network option in mobile networks but it will not work obviously :P

    HELP!
    I tried updating my ZL via PC companion today, and somehow I missed the part where I’m supposed to disconnect the USB cable and reconnect while pressing the Volume Down button.

    The phone just shut down by itself, and the Update process went on as usual it seemed, but after 2 hours, the update was still stuck at “Downloading…” and the phone screen remained totally blank.

    I was worried and wondered if I should unplug and reconnect according to instructions. But in the end, I cancelled update instead. And again, it’s been an hour and it’s still “Cancelling update…”

    • Anurag Kumar August 11, 2013 at 12:37 am - Reply

      Hey, download Sony update Service software and try installing the update via it…it will be ok…

      • Joyce August 11, 2013 at 12:48 am - Reply

        Thanks Anurag Kumar! Your advice was reassuring.

        I finally had the guts to disconnect the phone, and it’s now able to turn on and work perfectly fine.

        I guess I’ll try updating the software again later today. Enough scare for a night. haha..

        p/s: excuse me for double posting earlier.

        • Anurag Kumar August 11, 2013 at 12:50 am - Reply

          it happens no issues :)

          Just switch off your phone > Keep battery 50% + > Open SUS > Run it > when asked to connect > Connect phone pressing volume down button > As soon phone is detected you can leave button > Now SUS updates it.

          • Joyce August 11, 2013 at 12:55 am - Reply

            Just to be sure, what should I see on my phone after I connect the phone pressing volume down button and SUS detects it? Will there be any display / LED notification, or absolute blank?

            • Anurag Kumar August 11, 2013 at 10:47 am - Reply

              Green blink of light once…SUS will say phone connected and downloading progress will be shown…

    I have the 6603 model bought directly from Sony here in the UK. I received the original 4.2.2 Android update a couple of weeks ago and it caused one extremely irritating problem. When the Xperia connects using Bluetooth to my BMW, it did not transfer the contents (phone numbers and associated names) onto the screen of the car. So to make a call, it became necessary to pull out the phone and use the dialer on the phone (illegal while driving here in the UK). Today, when I connected the Xperia to the Sony Companion on my PC, my operating system was upgraded again (full upgrade 750 MB – not a patch. I still have Android 4.2.2 but now it’s build number 10.31.A.0.244 and guess what… the phone works perfectly in the car, transferring my whole Contacts list onto the in car handsfree system by Bluetooth. I guess the Sony helplines had been inundated with calls about the various bugs as it’s unusual for large Corporations to react so quickly. They usually spend a month denying that anybody (other than you) has had any problem like this. Well done Sony!!
