Unlock with normal method or testpoint (drm data keept)
Get root/cwm
Find your rom and fitting kernel
Flash.
If you just go first to general selection theres a lot fully made threads about unlocking and getting CWM. (on top, the pinned ones)
Then go to dev. selection so find your rom and follow the guide to flash

I'm struggling to find any guides. I only want to flash so I can get a ROM that has auto brightness turned off as on the stock ROM it's really annoying. Do I NEED to unlock my bootloader first?

Please could you break it down for me?
I'm so confused

You guys can't search? It's on stickies :/

So I don't need to downgrade anything??
In those steps where do I flash CWM?

nope not required..this is the best short cut and time saving + safe...try it and let us know..
CWM is in custom kernel..u dont need to flash it seperately...

Just flash a kernel & you can use CWM to flash a rom

Thanks,
Do I just follow the steps in this link

If you have BL unlocked, just flash a Kernel with CWM in it.

No image tutorial. Plain text.
DRM keys are Digital Rights Management keys. You will lose these when you unlock your bootloader. TrackID and some other (not really important) Sony apps won't work.
So, first, go to http://unlockbootloader.sonymobile.com/ and download the tools needed.
There you have all the steps needed to unlock bootloader.
After you've unlocked bootloader head down to the CWM thread and download the flashable file. You have the instructions at the thread.
Flash CWM and the phone will boot in CWM mode now. Remember to put the ROM you want to flash on sdcard, or put kernel.sin file so you can boot back in the system.
Download the Root.zip flashable file for cwm (you'll find it in most of the root threads), and put it in the root of storage.
Then flash the CWM through fastboot, and the phone will boot in CWM recovery.
Navigate to "Install zip from sdcard -> Choose zip from sdcard -> "root.zip" (use the volume buttons to navigate and power to select).
Select Yes and your phone will be rooted.
If you want, you can download a kernel like Advanced ICS which will autoroot your phone when you flash it.
If you don't flash another kernel, then power off the device and boot into fastboot mode, and flash kernel.sin.
Your phone will boot into the system and will be rooted

That's not how you unlock bootloader, that's how you check if your bootloader is unlockable. Head over to Bootloader Unlock thread and unlock your bootloader, then flash a CWM recovery through fastboot, and flash a kernel which will root your device.
There is Jelly Bean for our device, AOKP, CM10, PA etc etc.. Use the search button!

[Q] flashing kernels with flashtool

Flashboot is not a software , you can flash kernel using flashtool.
You need flashboot to flash kernel, If your bootloader is locked you don't have access to fastboot.
So unlock boot loader first
Read this tutorial.
Its easy.

Read this to learn how to use fastboot in flashtool to flash kernels: http://forum.xda-developers.com/sho...img / kernel.elf / kernel.sin using flashtool.
Remember your bootloader needs to be unlocked! And that kernel isn't auto rooted as far as I know, it's just stock kernel with CWM. But there is a file you can flash with that CWM to root, Doom has linked to it I think. There's another way to root as well, bset check a few more threads.

ROOT firmware .569 and install dual recovery (UNLOCKED)

i tried rooting the new firmware and it was a success, i now have root and dual recovery installed on stock 4.3
here's the other link i posted http://forum.xda-developers.com/showthread.php?p=48805157#post48805157
here's how. (my device is locked BL)
LINKS UPDATED!! (recovery)
1.Backed up my TA Partition
2.Flashed the official .569 ftf using flashtool
3.Unlocked my ZL's bootloader
4.Flash this kernel to get recovery (thanks Minthun46) http://forum.xda-developers.com/devdb/project/?id=700#downloads extract the boot.img and flash it using fastboot or flashtool (fastboot mode)
5.Flash Supersu fix zip and dual recovery (thanks NUT) SUPERSU fix.zip http://nut.xperia-files.com/download.php?dlid=U3VwZXJTVV9maXg=
recovery that i used http://nut.xperia-files.com (download the latest flashable zip for ZL)
6.Re flash .569 ftf exclude everything except kernel and fotakernel.
7.Restore TA Backup.
FOR UNLOCKED BL
just follow step 2, 4, 5, and 6
VOILA!!! device is now rooted and has working recovery
PS
Will only work for ZL that can be bootloader unlock.
Hit thanks if it helps you.

Don't put Locked BL in the title, you only managed to root because your phone was unlockable. Putting Locked BL in the title states that your bootloader can also be locked for this method to work, and but unless your ZL can be bootloader unlocked, this method cannot be used for locked BL

It will reset your device if u put a check on wipe apps log on flashtool. I recommend a clean install to avoid problems.
