Root Xperia Z2/Z3 Lollipop 5.1.1 Build 23.4.A.1.200

Last month Android Lollipop 5.1.1 was rolled out for all SONY Xperia Z2 and Z3 devices. Now it is available in all regions. I had published a post to root these two devices with Lollipop 5.0.2, but after updating to 5.1.1, it is not easy as before to root.

But, if you want to upgrade to latest version and root it, then this post is for you. To Root Xperia Z3/Z2 Lollipop 5.1.1 Build 23.4.A.1.200 is easy for an expert, but may be difficult for a beginner. I’ll try to describe it simple, for that all users can do it.

There are two sections; one is for previously rooted users of Z2 on 5.0.2 and another is for Z3 users. Obviously, it is too easy for already rooted users. I have a Xperia Z2 phone, so the below tutorial is base on Z2. Z3 users can try their own. Let’s get started.

Root Xperia Z2 on Lollipop 5.1.1 (Rooted Users)

Root Xperia Z2/Z3 Lollipop 5.1.1
You can check the tutorial to root Xperia Z2/Z3 Lollipop 5.0.2 Build 23.1.A.1.28. Before proceed to root, you need an already rooted flashable .zip file of version 5.1.1 to flash on your phone. Xperia Z2 is available in two models; D6502 and D6503. Check your model number in phone’s Settings >> About phone >> Model number.

Rooting Procedure

3) Now choose Install/Install Zip option from the Recovery menu.
4) Browse the downloaded ZIP file and complete install.
5) From the main menu, choose Wipe and Format Options and tap on Wipe Cache then Wipe Dalvik/ART Cache.
6) Now Reboot the phone. You are done!

Root Xperia Z3 on Lollipop 5.1.1(Rooted Users)

You can follow my previous article to root Z3 on 5.0.2. After that, the Z3 rooting procedure is same as the Z2 on 5.1.1. But you need different flashable ZIP file for that.

Downloads

Download From XDA-Developers according to your model.

I have tested on my Xperia Z2 and it is working fine. Above procedure works on both locked and unlocked bootloader and don’t worry about the data loss. If you have any question regarding this, then feel free to comment below and if you get success, then please mention below.

  1. Hi Sir! i am a beginner in this , i bought a used Z2 phone, and the owner said that he upgraded the OS to 5.1. How do I find out this "build" number? And can I root it safely?Thank you

  2. Hi my Z2 is at android 4.4.4 build no. 23.0.1.A.0.167

    Can I follow your step by step instructions right away?

    Or do I have to update to Lollipop 5.1.1 Build 23.4.A.1.200 first?

  3. Hey Sir :) Do you have a method rooting for Android 5.1.1 Lolipop , build number 23..4.A.1.232 & my model number is D6503 Xperia Z2? Hope ya can help me. :D Thx in advance. :D

    • If you want to root un phone.. Download emma flashntool from sony mobile website then flash it..it will down grade to 23.1.A.1.28 then after that follow what chandan guide to root then update it to 23.4.A.1.200 that so easy dude

  4. Hi !

    For your information, a new update is being deployed (23.4.A.1.232) , I had the update information this morning but did not let the update run.

    Any news about this update ?

      • copy that, no problem for me :) i was just giving you the info (even if I think you don't need anyone to know about updates ^^)

        for now i'll keep my rooted 23.4.A.0.546 which works like a charm (thanks to you) and will just wait for a stable way to have my phone updated / rooted to the last release :)

          • hi again :)

            sorry to come back and ask a confirmation, but I have a D6603 model and your link is for D6633, so I guess this is not the link I need. I found another thread on the same forum for D6603.

            My question is about the languages of these releases, what mean NCB, MEA, CE1, or BAL ? I'm french, and using a french version of 23.4.A.0.546 for the moment. If I understand correctly, US stands for american version and UK for english one, right ? What are the differences between 2 "english" roms ?

  5. Not sure exactly how to revert, hence my original post………………

    Hi chasing some help if you have some time.

    I have a bluetooth
    issue with my Z3 compact. Since lollipop it will not connect to any of
    my bluetooth devices (3 x vehicle). I rely heavily on bluetooth whilst
    driving. It recognised the vehicle and the vehicles recognise it, but
    the pairing process always fails. Took the problem to one of the motor
    vehicle companies and the tech told me that he has had number of people
    with the same issue since recent upgrade and in laymans terms the phone
    was now too advanced for the vehicle bluetooth and the only way to fix
    it was to take your phone backto settings before upgrade.

    So I have a Sony Z3 Compact D5833 with 23.4.A.0.546.

    How
    do I take this phone back to before lollipop??? I think I need to root
    the phone and flash the old software?? Cant seem to get phone into
    recovery.

    I have been unable to find one complete instructions to
    fix. Everytime I start some instructions I get referred away to do a
    certain step which usually seems to conflict with the first set of
    instructions……blah blah blah.

    Any chance you can lay it out for me in a step by step way that fix this issue?? Or perhaps refer me somewhere???

  8. Hi Chandan. I want to confirm if I install the downloadable rooted 5.1.1
    zip file for my Z2 will it reset my whole phone ? Will my apps and data still be there ? Thanks.

  9. I updated ad did all the steps and it seems like everything worked out, but my sim isnt showing up anymore, is there a fix for this?

        • Is formatting the only solution, I read somewhere that it's possible to flash a modem, but I'm not saying that it doesn't work, the steps are really simple and that what I did

          • Ok today I attempted to go into recovery and I get stuck in a powering off loop but never turns off to go into recovery, so the only way for me to turn it off is pressing the hard reset button and it still doesn't go into recovery even if I press the power and up button?

          • I got into recovery wipe/formatted in every way possible and even reverted back to 5.0.2 and I'm still having the same problem :(

          • Dear Sir
            Please let me know if you were able to solve this problem of no base band, because i got the same problem and i couldnt solve it.

          • I did some research on the problem so imma attempt to use this solution –> http://forum.xda-developers.com/xperia-sp/general/how-to-fix-network-baseband-missing-imei-t2865378

            but of course this is on the Sony Xperia SP, but I’ll just use the correct files for the Z2 but follow the steps when I get a chance, but I’ll let you know

          • For some reason i've been trying to post this link but its not letting me do so, but I think I have an answer for you but I haven't tested it yet

          • please let me know how were you able to get into recovery mode because mine is stock in power off loop for long time and when it does restart , it restarts normally it doesn't enter into recovery mode

          • Sorry i didnt even see your comment the first time, but honestly I had the exact same problem where mine wouldnt even turn off, so I just hard reset it using the "red button" near the sim card….but honestly half the time I never knew how I got into recovery I just attempted it a bunch of times after a number of reset till it just booted to recovery at start, but I have a feeling the sim card not being present might play a role but I havent tested that theory in detail yet

          • my phone shows base band unknown. i followed up your step as my phone is rooted z2 on 5.0.1 . after i upgraded with rooted 5.1.1 i lost mobile signal and i couldnt enter into recovery mode at all by using NDR utilities. please help

  10. i ve done everything what you say

    guess
    it works
    now
    i am on cm 12.1 unlocked bootloader
    now i want revert back to stock with locked bootloader

  11. Hi Chandan !

    I understood that I have to downgrade my Z2 from 5.1.1 to 5.0.2.

    Do you have the procedure to do this?
    Where I can found the 5.0.2 firmware ? thanks

          • I would like to root my Z2 because I have to use an application whose work only on a rooted phone. This app will get back my files… Indeed I deleted my photos by error.

            So I think that if I flash an other firmware I will lost my photos definitely.

          • Hi Chandan,
            I have same issue of Deseo.
            So far I understood, i have to use pc for flashtool, isn't it?
            any option to downgrade to 5.0.2 without pc? Or may i derectly root my d6503 (200) without downgrade?
            pls help.
            kind regards – timothy

    • hi ! you just have to find a generic 5.0.2 ROM (easy to google it) and flash your phone with flashtool (very easy to use sofware) to install a 5.0.2 ROM over your 5.1.1.

      From then, you'll be back to 5.0.2 (with the advantage to have a generic ROM, which means no branded OS with phone operator apps, etc.).

      Just follow the easy step by step tutorial your find here to root you 5.0.2 device.

      Then follow the above tutorial to install a pre-rooted 5.1.1 OS and then, you're done :)

      very easy process :)

  12. Hi Chandan,

    My Z3 had just upgraded to 5.1.1 (unroot), but i still not very clear with your tutorial. So can I check with you that is it i need to follow your previous tutorial for (5.0.2) until I have installed the "XZRecovery" at (Step 4: Xperia Z2 / Z3 Rooting Process)?

    After that only i can download and install the new SuperSu zip for 5.1.1 from the recovery mode, am i rite?

    Thanks~

  13. I already have installed the 5.1.1 but have backup of 5.0.2 with the root clockworkmod . Can I restore to 5.0.2 , then do the flash procedure ? which the file to the D6643 model ?

  15. hi !

    i have the Z3 and followed your tutorial to root it while under 5.0.2 and it worked smoothly, thanks for that :)

    When you say "You can follow my previous article to root on 5.0.2. After that, the Z3 rooting procedure is same as the Z2 on 5.1.1" do you mean that the Z3 MUST be on 5.0.2 and rooted for this procedure to work ? Mine has been updated even if rooted from 5.0.2 to 5.1.1 and is now unrooted again, which is logical.

    Can I still use your tutorial or do I have to downgrade my phone from 5.1.1 to 5.0.2 and root it first for the procedure to work ?

    Thanks :)

    • Ya, you are right. Currently there is no easy method to root Z2 or Z3. So you must have to downgrade your Z3 from 5.1.1 to 5.0.2 and you know the rest of the procedure.

      • thanks for your answer !

        then I have to ask, since I don't have a clue myself, and I guess that could help a lot of ppl, would you have any advice for downgrading the Z3 from 5.1.1 to 5.0.2 ?

        Reseting to factory settings would be a solution or do we have to flash it to 5.0.2 and how does that work ?

        As I understand all that, my guess is when an update on your phone shows up, do not upgrade it, keep it rooted and wait for a solution to come up, am I right ?

        But I'm now stuck with an "official" 5.1.1 and I'd like to get rid of it and be able to have 5.1.1 rooted device :)

        Thanks by advance, and sorry for my lack of knowledge about how to up/downgrade phones :(

        • You are right, until you get the solution of rooting, don't upgrade your phone. If you have already upgraded, you need a P and flash tool to flash the 5.0.2 stock rom.

          • sorry, another (and last) question :)

            i found a website on which they made a tutorial to flash my phone and install a generic 23.1.A.1.28 (5.0.2) rom.

            Is this what I need ? From this generic rom, will i be able to root it thanks to your tutorial, then use the one above to install a 5.1.1 rom ?

            thanks again :)

          • little update to mention that this method worked smoothly as you advised :) simply found a 5.0.2 ROM, flashed it with flashtool. Then I used your root tutorial for 5.0.2 devices and finally used the one above to get a 5.1.1 perfectly rooted !

            Thanks !
