[Q] Locked bootloader , can i downgrade to root.

i recently bought a bell xperia z1, went on to the sony website to unlock bootloader to find that mine is locked, unlike the international version which has an unlockable bootloader.
ive updated it to see if the updates would unlock the bootloader but alas they did not, now im running :
model c6906
android 4.3
build 14.2.A.0.209
Main question :
Will i be able to downgrade and bypass the bootloader?
ive rooted a S2/Htc HD/ Desire Z in the past im just worrying about bricking my phone that ive had for less then a week.
and all other guides ive seen are for different versions, ive heard of flashing the 6903 stuff but that makes me worry way to much.
so pretty much want to know is it possible to do via downgrade to achieve root or should i just wait till a safer method becomes available.
sony bloatware is annoying

Yes, you can get C6906 Rooted with Locked Bootlader. First you have Read a bit more about it, starting with this thread and also watch the Video Tutorial.
You have to use Flashtool v0.9.15 to downgrade to .534 using Rogers FTF for your model from here.
When you are on 4.2.2 FW .534 Root it with Bin4ry Method, then Install Dualrecovery, SuperSU and Upgrade to your favorite latest Android Pre-Rooted, like KitKat Here or JB 4.3 Here.
Done.
Good Luck!

you sir are the man, followed the video and got root, now to find a rom to use.
edit : went to install a rom + gapps and had to do the whole process over again. right from flashing nuts custom. got stuck in a sony logo boot loop. zz
so attempt #2 with a different rom.
edit 2: was able to update to 4.4 kitkat so now i hope i can update my rom. since i was trying to do a 4.4 rom on the 4.3 firmware ?
edit3: nope stuck on sony logo so went back to nuts again... hrmm well atleast i could upate to 4.4 going to try boot to cwm and see if that works

Before I flashed mine I was reading for weeks, You did in few hours and I think to quickly. If the phone stuck in Boot logo, I think you did something wrong but I don't have the phone with me so I cannot tell.
Now you have to go back to stock, keep pushing Volume UP and Power, 3 vibrations, phone in off, keep pushing volume down and connect to pc in flashmode, flash a Stock FTF for your model from the link I give you. Now you phone should boot. Repeat the process to get Root and be careful.
Remember to Wipe Data, Appslog, Cache, every time you flash a Fresh Installation is recommended.

You should not connect the phone to the PC until the PC prompts you after flashtool has prepared the files for flashing

4.4 will need a 4.4 kernel.

Ok, that is why I saw in Flashtool Disconnect and Connect my device few times but never had a problem. Good to know.

i was able to go back and use flash tool to flash nut's ftf
so im on 4.4 kitkat rooted which is good.
but when i flash any custom rom trough any recovery it boot loops im guessing its because locked bootloader.
so im guessing any rom i want to flash has to have 2 parts. The flashing process in recovery and the flashtool flash firmware for that rom.
unless like you said update my kernal

[Q] Is it safe to update?

Hi.
I'm from Portugal. My operator is MEO. I have an SP model C5303 with android 4.1.2 - 12.0.A.2.254. It´s rooted and it has CWM-based recovery v6.0.3.2 installed.
Received a notification update to oficial 12.1.A.1.205.
Is it safe to update? Is it possible to root the new version?
Thanks

After rooting Never recieve any OTA (Over the Air) update from SONY or Carrier as it will brick your device!
If you want to port to official 4.3 JB .205 Firmware then you should do it via Flashtool. Download your stock .FTF file and flash it via Flashtool.
Warning - While flashing your all data will be lost so it is advised to make a nandroid backup before proceeding!
Did I help! If yes then hit thanks

I will use flashtool
if I install one of these 5303 roms
http://forum.xda-developers.com/showthread.php?t=2311964
I suppose it will be unrooted after updating.
am I correct?
but I can't find the thread about how to root this 12.1.A.1.205

This thread is for firmware 12.1.A.205 root it with one click
And yeah you will loose your root access but if you're on UBL (Unlocked bootloader) it will stay that way only (your bootloader status will stay unlocked but root access would be lost after flashing the stock kerne)
Press thanks if I helped

will it brick? soft or hard?

hi to all xda members, just want to ask something i am just curios.
i have this device with firmware .108 and upgraded to .157
what i did was at .108 i rooted and and flash dual recovery then after i connected to wifi a system uodate is available so i updated the fw, and that time i didnt lose the root so now i am on .157, so what i did is back up the system with .157 fw.
my question is if i reflashed to .108 [downgrade] rooted it and with dual recovery, is it OK if i restore the .157 fw although i am currently on .108?will it brick my device?

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

Xperia Z1 Lollipop root

'Ello! I wanted to ask, is there a way to root the Xperia Z1 C6903 Lollipop 5.1.1 without having to downgrade it to KitKat? Or is there a way for me to downgrade and then upgrade back to 5.1.1 without loosing the root?
Thanks for the replies in advance.

Tip
Hi. There's a specific root tool for easy rooting called rootkitXperia, you can check here:
http://forum.xda-developers.com/crossdevice-dev/sony/root-how-to-root-5-0-lollipop-t3212108
But it supports only 14.5.A.0.270 and 14.3.B.0.310 (*Japanese model) firmwares. Flash one of these firmwares, root with this tool, install XZDualRecovery. then download .368 firmware pre-rooted version. Then flash pre-rooted firmware zip using twrp/cwm, it's your choise. You can choose wipe memory or not to wipe. Up to you.
Hope it helps

You can downgrade to KK 4.4.4, root it, install custom recovery, and use a pre-rooted 5.1.1 firmware to go back to 5.1.1. Or downgrade to LP 5.0.2, root it, install custom recovery, and use a pre-rooted 5.1.1 firmware to go back to 5.1.1
