[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.

[help] need infos on latest rom and latest root method

hello I am an old Z user , but it got stolen 6month ago...
I just got a new one, I'm not a noob but I'm lost on what is the latest rom to install and the proper way to root it as I'm sure old methods aren't working anymore...
from what I roughly understood, you need to unlock the bootloader now?
if yes I would need help on that!
(I heard about some "framework" stuff to install as well)
thanks for helping !

latest ROM is 4.3 - build number 10.4.1.B.0.101
You only need an unlocked bootloader if you want custom ROMS such as CM, PAC etc with custom kernels. Cant flash custom kernels if on locked bootloader
Unlock bootloader - http://forum.xda-developers.com/xperia-z/development/tutorial-xperia-z-zl-bootloader-t2153261
To root you will need to be on a 4.2 ROM, once rooted you can install a recovery then you can install a rooted 4.3 ROM or custom ROM
Follow this method to root on stock rom - http://forum.xda-developers.com/showthread.php?t=2327472

Correct, you do not need to unlock the bootloader if you are going to install the 4.3 - 10.4.1.B.0.101 ROM.
You can either do this on flashtool by flashing a 4.3 FTF or you can root and install recovery and flash a rom zip file

Rooted with towelroot.What next?

Dear all,
I have rooted my device which is running 4.3 (c5502) (build number: . 101) with towelroot. Now i need to install any custom ROM. I came to know that it requires to install recovery first before flash any ROM. I stuck there..Can you please guide me. I didn't unlock my bootloader yet but I had my TA backup with me.Thanks in advance guys.
whatever u need to know is already there. just search for it. if u expect to be spoonfed then you really shouldn't mess with your phone
The thing is, do we really need to unlock boot loader to flash custom roms, or can it be closed just with root and recovery?
No one tryed it till now I think.
Greetings.

Yes for flashing custom Roms the bootloader must be unlocked and a recovery must be installed however if you want to flash a stock based Rom unlocked boot loader is not needed. Just Root and Recovery needed for flashing the stock based Roms. Correct me if i am wrong.

As @kingvortex mentioned use the mentioned recovery
Note: On a locked bootloader you can only flash stock based custom rom
to flash custom like CM11, PA and so on you need to unlock the bootloader
Unlocking bootloader will void the warranty

Help rooting?

Hello all,
Im totally confused as to how to go about rooting my device c6902. Ive owned a couple of android devices and Ive rooted them all, however....with this device and there seem to be different ways people have rooted from reading the threads and im totally confused, So far I have unlocked the bootloader, and upgraded the device OTA to lollipop .242 (before the bootloader was unlocked), I dont intend installing any custom firmware, just want root so I can use TB and maybe delete a few bloatwares with root explorer and use xposed.
Im confused as to whether:
1. I have to downgrade firmware to kitkat, just to get root, then upgrade back to official firmware?
2. Ive been under the impression that a custom recovery and supersu, is enough to get root. It doesnt work that way on this device?
3. I saw some oneclick root programs that worked on the z1 compact would any work here
Just trying to know more about the phone and understand, so any help is appreciated. Thanks in advance.

Using the guide on the link I just posted, you are not required to unlock the bootloader, unlocking the bootloader without backing up the TA partition can cause problems with your phone.
You need to downgrade to KitKat 4.4.4 with kernel 108, then root it with easyroot install supersu and rootchecker to make sure your phone is rooted, the use NUTs recovery to create a recovery partition, after that search XDA forums for a pre-rooted lollipop flashable zip and install that, and voila you should be on lollipop with root and recovery.
I am not sure about one-click root programs.

Thanks for your help.
I already unlocked the bootloader though. Do I need to downgrade the whole kitkat rom or flash just the kernel? thanks
Figured out. Thanks
