Update lollipop firmware without downgrade to KK? - Xperia Z3 Q&A, Help & Troubleshooting

Is there a faster way to update the firmware without flashing KK, rooting and then reflashing the prerooted new firmware? Is this possible without loss of data?

Yes, just flash a lollipop FTF using flashtool.
If you want to keep root, just install recovery and flash a pre-rooted lollipop zip.
If you are currently not rooted and want root after update then you need to downgrade, root, install recovery and flash a pre-rooted lollipop zip

thanks!

If you have them, you need to remove the root and custom recovery.

Confusion with official Marshmallow upgrade for rooted stock rom

I flashed TWRP recovery and rooted my Moto g3 XT1550 but im on stock ROM itself. Now I got a OTA notification of Marshmallow update.
So, can I download the OTA & install it without unrooting or flashing stock recovery?

No! There should be no confusion here, the ONLY possible modification that can be done to your phone where you can accept a OTA update is an unlocked bootloader, NOTHING else. No Root, no TWRP, no Xposed... Your software status should show official and if the /system partition has been modified it will fail. PERIOD.
You cannot install an OTA without returning to PURE stock, not just unrooting and flashing stock recovery, you need to have an unmodified /system partition (root and then unroot is still a modified /system partition). Flash the factory image that matches your current software, then take the OTA, and flash TWRP and root again.

Steps for unlock BL and root for 5.1.1

Hi
I want to unlock my bootloader and root my M2. So i should do that in this order?
1. Downgrade to 4.4.4 from 5.1.1
2. Unlock the bootloader
3. Update of bootloader (?)
4. Flash 5.1.1
5. Root 5.1.
Is that right or i should do something more or less?
You don't need to unlock the bootloader just for root. If your gonna downgrade to KK just flash a pre-rooted zip via recovery on rooted KK
But i want 5.1.1 with root so if i downgrade and root i will not be able to update to 5.1.1 (cause when you have root - you can make update and if you flash the newest firmware root will disappear).
I thought that downgrade is necessary for unlocking bootloader thats why i mentioned about downgrade.
I just want to have rooted 5.1.1 because i need to delete lot of garbages from the apps and other personalisations.
So flash a pre-rooted 5.1 zip via recovery on rooted KK(this is what I've done to get rooted 18.6.A.0.182 5.1on LB ). Or update to 18.6.A.0.182 then use the dodgy kingroot app to root then change kinguser to supersu. Unless you want to use cm or omni custom roms it's pointless unlocking the bootloader when root is available on locked bootloader
I think this thread about PhilZ recovery is perfect for me http://forum.xda-developers.com/xperia-m2/development/d2303-philz-touch-recovery-6-t3047492
Thank you for help!
Yes it's a good working recovery. Used to use it myself

Flashing new OTA update on rooted MotoG3

Motorola has released new OTA update of 371.4 MB in India.
I read that since I am a rooted user I must not try to flash this update.
I would like the help from xda to install these updates. Should I install stock firmware 6.0.1 first?
Two ways to do it
1. Flash stock ROM 6.0from factory firmware link. Allow ota to download and phone should upgrade to 6.0.1
2. Flash the 6.0.1 stock ROM which is made available in factory firmware link. -Update: 6.0.1 is already the updated system with the new ota of 371mb.
Option 2 is more convenient.
While upgrading to mm 6.0 via ota, on my rooted phone I had tried flashing the stock recovery and cleaning the root. but it did not help and I landed with a soft bootloop. The ota checks for the original fingerprint of the stock system which is why you need to be on stock firmware for the ota update method.
You need stock recovery and stock firmware.

S5 5.0.1 Update OTA or Odin?

I have a Galaxy S5 and it's on 5.0.1 Stock not rooted or Custom recovery. I want to install Blisspop 6.0.1. How would I go about doing this? Is it ok to install the 6.0.1 OTA and still be able to root and install custom recovery?
Edit: Ended up just OTA. Mod delete thread please??
It's probably easiest to update OTA, since it will preserve your apps, data, & settings. I wrote a step-by-step tutorial on how to update OTA to 6.0.1, install a custom recovery, and root. Here you go...

I believe blisspop is still based on 5 firmware. If you update you'll just have to go back to OK4 firmware to run it.
