      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.

@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 :)

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?
- um009 says:
  
  September 11, 2015 at 6:35 pm
  
  @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.

    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! :)

Hi all, I'm having a problem flashing the pre-rooted firmware in CWM recovery. I shows:

Finding update package...
Opening update package...
Installing update...

Install from sdcard complete...
This takes a few seconds and than stops.

Is CWM and this pre-rooted firmware incompatible or is there something missing in the firmware package?
Please help.

Thank you

Marco

  @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. says:

  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.
