[Q] Upgrading from Kitkat to 5.1 OTA update - Sony Xperia Z Ultra

I downgraded from 5.0.2. to KitKat because of the memory leak, I have rooted and backed up the TA partition. I haven't installed any recoveries, but my question is, if Sony do ever release the 5.1 update through OTA would it be ok to upgrade?
Not GPE Z Ultra
Thank you

[Q] can i lock my bootloader once i flash android 5.0 rom

Hi,
I have flashed android L rom in my nexus 5 since i didnt get an OTA update. Just want to how to lock my bootloader again and how can i get the OTA updates in the future.

From 4.4.2 to lollipop?

Hello guys,
My Xperia z2 is currently running in 4.4.2 firmware.
I have got update notification ? for 4.4.4
But I am waiting for 5.0 , is it possible to directly update from 4.4.2 to lollipop through ota (without flashing ftf . )

Ok so since lollipop hasn't been released yet, I don't think anyone will me able to answer your question certain.
I would assume no. Ota updates I thought are updated system files and not a full rom. There may be a prerequisite to have some (or all) 4.4.4 system partition to be used as a base for 5.0.
I think you will have to do at least two updates. (first 4.4.4 -> phone updates and reboots -> new update notification for 5.0)

[Q] How do I install official lollipop on my Sony Xperia Z with unlocked bootloader?

So, I asked a friend to install cyanogenmod lollipop on my device couple of months ago. Now that the official Xperia update is out and because I don't like cyanogenmod, I want to install the official lollipop release on my device. Currently I have official sony android version 4.4.4 flashed on my rom. My phone's bootloader is unlocked so, I can't update it through the official OTA release. (Also, I do not have a backup of my DRM keys)
So either help me re-lock my bootloader, or tell me how to flash the official Sony Xperia Z lollipop on my phone!
Device: Sony Xperia Z (C6602)
Current Android Version: 4.4.4
Bootloader: Unlocked

I'm in the same boat. Indian Moto E 4.4.4 rooted with TWRP 2.7.1.0. I haven't removed system apps or installed xposed.
I've been unable to upgrade yet, because I haven't found any instructions that I can be sure apply to my case. From what I gather, I think we're supposed to flash stock rom. I don't know if we have to relock the bootloader though (or flash the stock bootloader?). Still confused
Dont worry guys, no need of upgrading hassels, just flash this zip in TWRP http://forum.xda-developers.com/moto-e/development/rom-stock-motorola-lollipop-rom-t3167111

If I install it and I don't like it then can I not just reinstall the lollipop image?

I have an official lollipop upgrade rom downloaded and installed on my huafung-bungding-giggling mobile and it works great
I have now found an official marshmallow upgrade but it says
"there’s no official rollback available right now, so you’ll have to stay on Marshmallow for a while."
If I install it and I don't like it then can I not just reinstall the lollipop image?
Please be clear with your words,
Now what ROM you are using and also let me know with andriod ver.???
Originally running Android 4.4
Recently found Android 5.1 rom official upgrade
installed and working peachy
Now I have found the official Android 6.0 rom online update for my phone
My question is if I install the marshmallow rom and I don't like it. If I have the lollipop rom what is to stop me installing it back?
I'd there something that I'm not getting, that would prevent me rolling back?
Actually I'll just go for it
