[Q] Downgrading on locked bootloader

Hi guys!
I have searched the forum and I DO have got a lot of answers. But still I want to get some things clear before I go on.
I just got myself an Xperia Z. It was already updated to 4.3 .569. The phone has a locked bootloader and I found out that it CAN´T be unlocked. So there I´m stuck.
I was first thinking about following this guide: http://forum.xda-developers.com/showthread.php?t=2590088
But then I got some more questions.
If I downgrade according to that guide... since I get a custom recovery, can I flash any custom ROM that is made for locked bootloader? Do I even have to use the 4.3 .569 used in the thread above or can I just downgrade and root then choose the ROM to my liking?
Thanx for all your help!

Downgrading
Dear friend:
1-the easy way::laugh:
2-Flash 4.2.2 with flash tool
3-Root on locked boot loader
4- Install Dual Recovery follow
5- Install 4.3/4.2 Pre-rooted or any other rom of your choice.

Once you've downgraded, rooted and have a custom recovery, you can use any rom you like, as long as it's a stock based rom for locked bootloaders.
You cannot flash anything based on CM/PAC/AOSP/AOKP etc as they require a custom kernel and therefore an unlocked bootloader.

Rooting

I have latest official firmware JB 4.3(12.1.A.0.266).
Now i want to root it.
Is there any way.
Thanks

Yes there is. However you need to unlock your bootloader for this.

However for unlocking bootloader you need to create a backup of the TA partition and this requires root.
So there is an loop in this issue.......
What some users do:
- Downgrade back to 4.1.2 (see my tutorial about Flashing with Flashtool)
- Root it
- Backup TA
- Unlock bootloader/Install CWM
- Install custom 4.3 rom with root

Those who do not want to unlock bootloader are waiting for @DooMLoRD to release an exploit for official firmware JB 4.3(12.1.A.0.266).
I am one of them.

Yes

Don't think you'll get an answer as this question has been asked countless times.
As of last month, you don't need to unlock the bootloader to get root on 4.3
But you need to downgrade to 4.1.2 (257) and root using doomlord's exploit. Then install recovery. After that choose a rom of your choice (based on the latest .266 or .201).
For noob's infor:
a. the downgrade is necessary as you need root and doomlord's exploit for rooting works only up to version .257.
b. rooting is simply needed so that you can install recovery (CWM is good)
c. after which all will be wiped out by the new rom which will be flashed with its recovery and root :good:
And before you ask where these files are: search in the various forum, notably "android development" and "General" sections

You'll need flashtool to flash .254 (full firmware). Note that flashtool will only work if all the drivers are installed in your computer (there is an installer inside flashtool directory, after installation - double click on that to install the drivers)
Hunt around for the .254 ftf and .257 (kernel only) if you can't locate it in the link I gave you.
[The .254 in the link is "kernel" only - you want the full firmware (http://forum.xda-developers.com/showthread.php?t=2311964)
The link to cwm: http://forum.xda-developers.com/showthread.php?t=2649923 but I prefer this one (simpler): http://forum.xda-developers.com/showthread.php?t=2444605

CM 11 BL- Help

Hello guys, im new to all this stuff and i dont really know what i have to do first in order to get CM 11 installed on my Bootloader locked phone.
Its so confusing, i dont know if i have to root my device first, or install a recovery or unlock my bootloader first so im able to root it etc.
Can anyone help me what to do first? im on the 4.3 Update
abload.de/img/screenshot_2014-05-02weo0t.png
the reason why i want to have CM 11 is because ive read that this rom is way faster than the 4.3 stock, also it has better ram management (?) and doenst lag as much as the stock one.
Also why i want to have the BL version is because i dont really want to void my warranty.
I hope you guys can help me out with a nice step by step guide for someone who thinks all those different steps are getting confusing oh and im sorry for my english ^^ im from germany

Sounds legit, in order to root my phone, i have to downgrade to the very first firmware and then use the doomlord method right?
after that i have to install the recovery, after that, do i have to flash a pre rooted 4.3 stock firmware or can i go straight from the very first rooted stock FW to the 4.4.2 rom?

you will need to downgrade,root it,flash recovery,flash pre-rooted 4.3 rom,then 4.4 Rom...
make a backup of 4.3 rom using recovery in case you want to revert.

Yes, downgrade, root, install cwm, install CM10.2 for LB, reboot recovery again and install cm 11 for lb

You are mostly right
You need a to be rooted, I suggest you use the 23.0.A.2.93 firmware to do this (4.4.4 - kitkat)
Have a custom recovery (click links to go to the posts)
Then flash a pre-rooted lollipop firmware
Sadly in lollipop they fixed the SuperSU Survival mode so the only way to get root is to flash a pre-rooted firmware

You will loose root if you update through OTA or through computer
You will keep root if you flash a pre-rooted firmware after gaining root on KK
