    @anurag news and updates are coming for xperia z everyday.. but nothing for xperia z1 ? what the heck is this ?

    • Anurag Kumar February 8, 2014 at 7:47 am - Reply

      Mate z1 just got this bug fixing update 1.136 firmware which Xz has got now so you should be happy that you got it before them..

      Now if any more bug fixing update comes for Z1, i’ll be surprised…minor can come.

      Now expecting KitKat soon in a month’s time frame hopefully 😉

      • Oscar February 8, 2014 at 8:18 am - Reply

        Rumours say the Android 4.4 – Kitkat for Xperia Z1 may potentially roll out in next week.. Is That True..?

        • Anurag Kumar February 8, 2014 at 8:42 am - Reply

          Never trust rumors but sure not coming in a week, hope we see Sonys official statement on it soon.

          We think KitKat will be shown on Sony D6503 at MWC event first then Z1 will get it…otherwise no point of making KitKat exclusive…

          If internals are to be trusted kitkat is not coming for next one months its still in testing firmware very buggy not stable.

          • Oscar February 8, 2014 at 9:50 am -

            we expect move2sd and 4k recording in android 4.4 update

          • Anurag Kumar February 8, 2014 at 9:54 am -

            I expect 4K to be there but don’t think so move2SD will be there.

I love the SP very much its a nic phone bt the camera is below average…

    Hey m. Anurag I have Xperia Z running 4.2.2 Jelly Bean. If I would flash 4.3 10.4.1.B.0.101 singapore (my country is lebanon) I will brick my Device? Because another country and I will loose coberage? Freq of lebanon: LTE 1800 Mhz, 3G 900 and 2100 Mhz… And how to flash 4.3?

    • Anurag Kumar February 9, 2014 at 5:05 pm - Reply

      Mate Singapore FTF link is for Xperia ZL, DO NOT flash on XZ it will brick your device.
      You are only allowed to flash XZ any region ftf on any region XZ device.

    Good day Mr. Krumar. I just have a question, im from the philippines, i bought my xperia z in indonesia, c6603. it doesnt update to any firmware. thats why i decided to use flashtool. and luckily it worked, now im running adroid 4.3.. is it possible that my country also changed? becaus im now receiving updates of walkman, and other sony apps. is it possible for me to receive the latest minor firmware update? thanks a lot.

    mr kumar? and one more thing.. is it possible for my phone to changed its base country after flashing.. by the way, i flash 4.3 with the use of ttf from europe.

    • Anurag Kumar February 10, 2014 at 3:49 pm - Reply

      Flashing some other region’s ftf will give you additional settings in menu, apps if lte or hspa network present there.
      Either your flash lte / hspa ftf lte will give some additioanl basesband settings.

      Flashing other regions ftf only give you regional app more if there is any. Your concern should be of lte or hspa ftf.

  13. patrick chan February 10, 2014 at 3:57 pm - Reply

    my lte is just working fine.
    i just want to know if i can receive any firmware update now that i flash another region ftf..

    by the way, thanks for the lightspeed like reply..

    • Anurag Kumar February 10, 2014 at 4:48 pm - Reply

      Yes you will get future minor major updates but depending upon the region’s roll out date. Every region has different update schedule, so you better flash back your region’s ftf whenever available.

    • Anurag Kumar February 21, 2014 at 12:28 am - Reply

      There is No ETA for OTA. One question to ask why everyone asks for OTA, why don’t you people update via PC Companion, what’s the problem.
      To Downgrade, flash the 4.2.2 ftf file, No root needed for flashing, no warranty void, no bootloader unlock needed.
