I want to upgrade from cm11 to Lollipop 5.0 (the version offered by Sony). I'm using flashtool. Would flashtool be enough for this job or would I need to wipe my phone first and do a fresh install of Lollipop on it?

Hi all, as the title I lost my Xperia Z1 stock recovery!
I had 4.4 with 14.3.A.0.757 firmware rooted and dualrecovery, and I updated to 5.0.1 Lollipop with PcCompanion. Then my Z1 became pretty slow so I wanted to flash this ROM http://forum.xda-developers.com/xperia-z1/development/5-0-rockz1lv1-1-deodex-advanced-mods-t3090064 on my phone, but I recognized I had not any recovery installed! So i flashed the 14.5.A.0.242 Lollipop firmware thinking I'll get back a recovery, but still don't!
How can I fix this?
Thanks

From taking what you have wrote, when you were on 4.4 kitkat you rooted your phone and put dual recovery on, your mistake was to upgrade to lollipop using the PC companion instead of finding a pre-rooted lolliop on these forums, hence the reason you lost recovery, the only way to get it back would be to go back to kit kat and then root your phone put dual recovery on flash the firmware you want from recovery.
Hi, I'm still on a pre-rooted 5.0.2 stock rom based on this:
http://forum.xda-developers.com/z3-compact/development/z3c-usa-variant-lollipop-pre-rooted-nut-t3071069
My question is: How would I go about updating to 5.1.1 without losing root? Would I have to flash the 5.1.1 firmware via Flashtool again? If so, does anyone have a stock pre-rooted US firmware? I also have a locked bootloader, and I'd prefer to keep it that way for the better camera. Thanks!
I have an Xperia Z and recently I unlocked the bootloader.
However now I cannot install (upgrade) to the Lollipop Android 5.0 (10.6.A.0.454) from Android 4 (10.5.1.A.0.292).
Please advise on a step by step process since I am not experienced.

'Ello! I wanted to ask, is there a way to root the Xperia Z1 C6903 Lollipop 5.1.1 without having to downgrade it to KitKat? Or is there a way for me to downgrade and then upgrade back to 5.1.1 without loosing the root?
Thanks for the replies in advance.
Tip
Hi. There's a specific root tool for easy rooting called rootkitXperia, you can check here:
http://forum.xda-developers.com/crossdevice-dev/sony/root-how-to-root-5-0-lollipop-t3212108
But it supports only 14.5.A.0.270 and 14.3.B.0.310 (*Japanese model) firmwares. Flash one of these firmwares, root with this tool, install XZDualRecovery. then download .368 firmware pre-rooted version. Then flash pre-rooted firmware zip using twrp/cwm, it's your choise. You can choose wipe memory or not to wipe. Up to you.
Hope it helps

This won't work as the OP stated that his phone is on 5.1.1

You can downgrade to KK 4.4.4, root it, install custom recovery, and use a pre-rooted 5.1.1 firmware to go back to 5.1.1. Or downgrade to LP 5.0.2, root it, install custom recovery, and use a pre-rooted 5.1.1 firmware to go back to 5.1.1
Here's the skinny...I'm on bootloader version 30.b4 I have tried out CM12.1 after installing CM11 and rebooting. CM12.1 is working great except for a few inconsistencies. I want to upgrade as far as I can and have a working device. I have not flashed any boot.img files or modem files or done any alterations to the partition tables except what the official CM12.1 (following their method of installing CM11, rebooting, then flashing 12.1.
Here are my thoughts.
Flash the stock 4.4.2 sbf and OTA as far as I can and be where I end up.
Flash the official .sbf for LP5.1.1 and update bootloader, then try to get CM 12.1 installed again and hope it works better.
Go back to stock rooted 4.4.2 with xPosed and love it,
?..... What should I do and why?
I don't want to end up stuck somewhere that sucks and I need your input.
Thanks.
