View Comments

• My bootloader was locked & i had root access. When i flash the commercial & journalist ftf 10.4.B.0.569 i lost root access. I would like to know how can i root it again. I'm using Xperia z c6603

  • Use this guide https://techbeasts.com/2013/12/20/root-xperia-z-android-4-3/

• There are rumors that 4.3 update on Xperia devices eats up RAM upto 1GB. Is it true??

  • @disqus_xSAPn2lrJx:disqus I didn't hear any such things, that maybe possible or maybe not, because the new builds are always better than the previous ones.

• AWESOME ...

• Hi. After i updated my Z to 4.3 (OTA) i noticed that my mobile data won't disabled automatically on low battery mode (i set mine to 20% battery).

• Five Star for Usama, my xperia Z Updated ! Jelly bean 4.3. Great Job Usama & Good luke

  • @disqus_Qe4p0eTrtK:disqus Glad that it worked perfectly for you! Enjoy

    • After the Update, i have this issues with xperia Z : first i can't any more recorde voice msg in facebook messenger (it say unable to record voice), Seconde issu i can't hear anything in VIBER and i can't be heared, the same in WHATSUP can't record voice message. plz post !

      • @disqus_Qe4p0eTrtK:disqus Flash the same firmware again, but wipe your phone this time.

        • I can't understand what did you mean by saying "but wipe your phone this time " plz explain ....ty.

        • @disqus_Qe4p0eTrtK:disqus when you flash this firmware using flashtool, select wipe data on the right side inside the tool and then flash the firmware.

        • One more question: in this topic the android 4.3 file is 700mb, in the other topic the Android 4.3 file is 800mb. And they are uploaded in different source. Which one is the official and which one is the custom rom?

        • @disqus_Qe4p0eTrtK:disqus the one linked in this topic is official Android 4.3. You may go with it.

        • The other one is not official?

        • Dear ! it sounds bizzare to me, because you say this is an Official version. you mean the other is a custom one ? why then the topic there is called ''Install Official Android 4.3 10.4.B.0.569 Firmware.....''. What make me ask all this is the files sizes; the one here is about 700mb the other is about 850mb .....Please be clear on this. Because after i make deep search on the issues i have after i update it say that this kids of issues are caused when using Custum Rom. IF nothing here is not official OTA update Plz tell me that way you will help effectively. Thanks Usama

        • @disqus_Qe4p0eTrtK:disqus other may be for different model number. Please keep that in view. Firmwares are different for different origins and contain region specific apps that are called bloatware, these apps make it heavy. It's just simple as the other may have less bloatware and the one with 850MB has more.

        • While both are official roms. pick one according to your model number.

        • If you're talking about the above two..one is a torrent and one is a mirror.. you may go with any of these. Both work fine with C6603 and it's just a matter of pre installed apps that make it different in size.

        • Well, thanks a lot! Found a fresh RCT official ROM that was dedicated for Russia .... it works better for me and it resolved the microphone issue. The "commercial & journalist " that you have here it's from XPDA dev. Before Sony begging rolling out the updates in December of last year. For those how have issues like I had (read earlier comment) in my case that was Facebook causing it, when I try te record a voice msg it show recording & after I release the msg was not send and nothing happen. After this the camera was unable to record video because the mic was still blocked by FB, and all other app using mic like Google now, viber was unable to function correctly. I restart my phone and still iambic not trying to use voice msg in FB all is working well. Hope this will help.

• Interesting. I would like to try it near of next month. Mine is still 4.1.2

• where do we find voice recorder ? if it's not there then how are we gonna ge the previous recordings ?

• Good day Mr. Usama

  I’ve been making my researches over the internet until I stumbled upon your posts here at techbeasts. I have a sony xperia z phone and I have always wanted to update it to the latest android version but there aint OTA update yet, and kept trying with PC companion but to no avail. I am here in the Philippines and I am contemplating that that could be the reason why my phone isn’t
  getting the latest android version yet. However, I read some blogs of xperia owners here in the country saying they have already updated their units to the 4.3 jelly bean via PC companion, and what’s funny (dismaying for me) is that they said their phones are either xperia sp or other earlier/midrange xperia devices. I am not belittling their xperia phones or whatever but my point is,
  shouldn’t my Z could have at least been on top of the priority for android update, given that it’s the first high-end flagship phone produced by sony.

  Anyways, going back to my story, I am in deep desire to really have a taste of the latest android
  version as I have been reading a lot of good reviews from xperia owners on how their units have improved due to updating. My xperia z has a model no. c6603; runs android version 4.1.2 and build no. 10.1.1.A.1.253.

  I am not a tech wizard myself and I am new to techie terms like rooting, flashing etc., but I’m sure I can keep up, given the vast support, guides and explanations tech wiz like yourself, do provide us in the internet.

  Now, like I said earlier, I stumbled across this post and I am so close to following your guides to feed this update on my phone but I’d like to know a few things first:

  1. Is this above the official android 4.3 update for sony xperia z?

  2. Will updating thru this process void my sony warranty?

  3. Will I be able to receive additional updates as well as the android 4.4 kitkat soon, if I follow the above process?

  4. If I did follow these steps and let’s say some mishap happens within the process, will I be able to go back to my original android version? How?

  Pretty much, this are my questions (probably for now), and I do really hope you can help me with it.

  Thanks in advance.

  • @boyadobo:disqus thank you for paying us a visit.
    You may not worry about this anymore.
    The above guide is accurate.
    This firmware is official firmware for Xperia Z.
    You won't loose your warranty.
    You will receive all future updates as well.
    Warranty is only void when you unlock the bootloader of your device, while the above guide doesn't require an unlocked bootloader.
    If something goes wrong, you can easily start the whole process again and install the firmware from scratch.
    If you want to go back to your old firmware if something goes wrong,, you will have to create a Nandroid backup and for that you need a custom recovery, however there is no need to worry about it and you may update your device without any fear.
    I hope that this goes fine for you. If you got any further questions, please feel free to ask.

    • Hey there Mr. Usama.
      I've been busy for sometime until i had this chance and paid a visit here today and finally updated my phone.

      Wow! as far as right now i'd say the update is awesome. At this moment I'm typing I'm restoring my contacts, msgs etc but I cant wait to tell how glad i am for deciding to go for the 4.3. I hope there won't be any issue at all after i did the update, though i know for sure you'd still help me if there would be any ;)

      Regards and big big thanks!

      Ps. the AR effects are not there (not a big deal though)

• hello Mr. Usama

  is it worked on all C6603? on all build numbers and regions? because my xperia is on Indonesia region and the android version is 4.1.2 and build no. 10.1.1.A.1.253

  Thank you :)

  • @timothiusadrianadiwinata:disqus yes it will work on all C6603 and for all regions. You can update your device without any fears.

    • 1 more question Mr. Usama

      yesterday, i have downloaded the .FTF file that you mentioned above via internet download manager..
      but the format of the file that i download was .zip not .FTF
      but if i download it via chrome browser the format was .FTF..
      is it okay if i just change the format from .zip into .FTF? Bcause if i download it from the start, it will take more time..

      • @timothiusadrianadiwinata:disqus It's kinda strange, the format actually is .FTF and Internet download manager shouldn't make a difference. I'm not sure about this, I suggest you downloading it using chrome and then flash the FTF. Sorry for the delay in reply, I've been away for a while.

• @boyadobo:disqus
  thank you for the feedback.
  Stay connected and Enjoy :)

  • Good day Mr. Usama,

    I forgot to tell you I also have a Xperia Tablet Z SO-03e (docomo) model and i have been checking the internet and forums on how i could possibly update it to the latest android version. I was struck with this page http://forum.xda-developers.com/showthread.php?t=2589701 but i'm not yet sure i'd pursue with the steps given particularly its not a bit clear and i find it confusing. Knowing your expertise on these things, i came up to you hoping you could help me out with this too. Thanks in advance.

    • @boyadobo:disqus this will work for you, you need to put a little effort here: http://forum.xda-developers.com/showthread.php?t=2759141
