Can please someone confirm this will work?
1. Downgrade to JB 4.2.2 14.1.G.1.534
2. Install locked dualrecovery 2.7.97 BETA
3. Flash KK 4.4.0 14.3.A.0.681
4. Flash with CWM superSU
I am asking because I read somewhere the following method:
1. Flash KK 4.4.0
2. Unlock bootloader
3. Install CWM thru a very complicated procedure that requires fastboot
4. Flash with CWM supeSU
Now, my question is: since I could install dualrecovery for unlocked bootloader, to avoid ulocking bootloader, why not downgrade, flash dualrecovery, upgrade and flash su?
Can please someone confirm this will work?
1. Downgrade to JB 4.2.2 14.1.G.1.534 (and root it)
1.2 (Backup TA Partition !Important, for the future)
2. Install locked dualrecovery 2.7.97 BETA
3. Flash KK 4.4.0 14.3.A.0.681 (via recovery)
4. Flash with CWM superSU

If you're not going to unlock your bootloader then do not do it. you can also backit up when you're running kitkat with root.
But what's the harm? )

ok hold on a sec, I did not read carefulyy...
you are saying I need to downgrade and root, then flash dual recovery, upgrade and flash su
I thought I could avoid rooting after downgrading, cos I cannot download from anywhere any tool to root 14.1.G.1.534

I was hoping it would be less complicated...
I still do not understand why I have to root after downgrading...
After all, all I need is a custom recovery to flash superSU, and according to the guide all I need to install a dual recovery is. 534, no need to root it or to unlock it, according to the guide.
So if I do not want to unlock device and I do not care backing up TA, the following should suffice
1. Downgrade to. 534 with flashtool
2. Install dual recovery for unlocked phones
3. Upgrade to kitkat with flashtool using an official ftf
4. Flash superSU with cwm

Because you need root to install recovery

The post here is what I did straight from Kitkat. No downgrade necessary.
After doomlord kernel install, just install su.zip using recovery

it seems it is an endless loop: either you unlock the bootloader if you do not want to downgrade, or you downgrade first if you do not want to unlock

the easiest way imo is to just unlock the bootloader.
flash the kitkat ftf via flashtool as linked below

Just try it, you seem to be wanting extremely specific instructions and questioning everything you are told. Please try following them them asking for help as you go along, you never know, it might just work for you....
There is no need to unlock the bootloader if you downgrade, root, install recovery and flash a pre rooted rom. Please tell me which step of these instructions say "unlock the boot loader"

I guess u r rite.. so I am gonna unlock: do I loose any sony feature? (audio plus, x reality, ...)
Also, since I do not have a custom recovery, I guess I will have to flash the kernel via fastboot, whi h will give me the ustom recovery, then flash superSU with the recovery
What do I need flashtool for?

I know I know... all I wanted to say is: eithef I stay on KK and unlo k the bootloader to root, or I do not unlock but have to downgrade etc.
Unlocking at this point seems easier, safer and faster, as I will keep my current rom which works fine
I will do a backup with sony toll and restore afterwards
But once you downgrade, root and install recovery you just flash a pre rooted 4.4 rom... The one from NUT is made from a stock ftf file with the relevant root files added to it. I don't see the issue.
As for unlocking, read the information on the sony website about it. You have to unlock using that site anyway. You will lose warranty and drm keys. However, to be able to lock again you need to back up your TA partition otherwise you lose the drm keys forever. Now to do that you must have root, so you are going to have to downgrade and root anyway

The bootloader is not relocked when you flash stock FTF.
You will loose custom recovery and root.
Flash recovery and root again.

Hmm, don't worry about bootloader.
Let's keep it unlocked, which will help you in many cases.
I don't have a pc or any external way to install TWRP via ADB. Is there any way to install it without using kingroot(or rooting at all)?
I want to install Lineage.
Update1:Bootloader is unlocked via dev options
Update2:My mistake on the bootloader being unlocked, thanks for pointing that out)
Update3: I guess I will just need to get a PC for a day or two. But once I have TWRP installed I can load Lineage+GAPs just through TWRP right?
No, you have to make a backup of everything on the phone and unlock bootloader in order to flash anything. You can't do this without PC.
Nope, you need Fastboot to flash TWRP to the Recovery partition unfortunately. Since you need to unlock bootloader first, you cannot use any one-click root app to root on a locked bootloader. After unlocking bootloader you can flash TWRP then. All this needs to be done on a PC with ADB/Fastboot drivers.

Through "Dev Option" means he has OEM Unlocking enabled. Does not mean his Bootloader is unlocked.

You can't unlock BL w/o enabling OEM unlock first, can you?

Not really sure about this. As I remember, I never selected the Option in Developer Options when I first Unlocked my bootloader. This was over a year ago, and I never needed to relock and unlock my BL again. So, you may be right.
