  • Thanks for this very details and step by step in rooting Xperia Z model C6602 and C6603. Also wanted to know if this way supports all kind of Xperia phone. I am having this Xperia M4 Aqua and until now. Please let me know it support via pm or response in this comment.

    • @disqus_XfcLzqvPUo:disqus this method is particularly for Xperia Z. I will have a look on the status of M4 Aqua and update you in a day or two. Stay connected 🙂

      • OK thanks i will for your update

        • Sammer Banawa

          Hi im also on jelly bean 4.2.2, rooted and installed cwm, can I flash directly to 5.1.1 without flashing kitkat. 4.4.4? And if so, is it required to wipe system and cache? And is it only compatible in flashing using twrp ? Thanks

          • @sammerbanawa:disqus Flash the Pre-Rooted Lollipop straight away. Your device will be updated 🙂 After flashing wipe cache and dalvik cache. Also perform a factor reset prior to flashing the Lollipop firmware. Good Luck.

          • Sammer Banawa

            Thanks for your help usama

          • Sammer Banawa

            Why is it that after downloading the zip file, my antivirus detected trojan, and other malwares?

  • @EnriqueIglesias1:disqus Simply flash old FTF i.e. .283 FTF on your Xperia Z. The guides are already available on our site. Please use the search option to locate them 🙂

  • Ash Stone

    Hey, So i flashed the .283 on my c6602 and it’s been stuck in a bootloop ever since then. Is there any workaround solution to this?

    • @ass6ash:disqus Flash .283 once again properly and see if your phone boots up or not. If it doesn’t, then flash .222 and recover your phone.

      • Ash Stone

        Thanks for the reply. I tried .222 but it still ended up bootlooping. So I flashed to .454 (Lollipop 5.0.2), rooted using Kingroot, replaced kinguser with SuperSu by using SuperSu-Me app, then I installed TWRP and used your pre-rooted 5.1.1 lollipop ftf. Working all right now! 🙂

  • sadid

    hello… my xperia z is still in jelly bean… can i skip step 1 and just install twrp and cwm and flash your pre-rooted firmware ??? my current jelly bean is rooted …

    • @disqus_O50Gv1eVL3:disqus make sure that you’ve rooted and installed recovery, then you jump to the next step.

  • @disqus_2MaagQcHdQ:disqus tell me your device model number, I will find you another firmware .zip file.

    • Marco V.

      The device model number is C6603. But I managed the problem by flashing the unrooted firmware, unlocking the bootloader and installing TWRP and SuperSU. I decided to unlock the BL as there is no warranty on the device.
      Thank you for your help and also for all your guides.

  • @hitmansnip:disqus You can backup and restore data like contacts, call logs, sms messages and media content without root using different applications in play store, but you cannot restore application data or system data without root access.

  • sarath

    Hello everybody. I have already the dual recovery installed and running on a custom rom (Existenz 3.5.5 which is based on Kit Kat 4.4.4) with locked bootloader and root. Can I install this directly from the recovery without losing root? What do I have to wipe? System, Dalvik,Data?

  • Bijo P George

    Hi, I want to get root access to my phone just to install a recovery app and I need to unroot after I recover the files. My device is C6602 Android version 5.1.1 and Build 10.7.A.0.222.
