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 :/

EDIT : Retrosid is faster than me

no need to root dude if u want to install a custom ROM...just unlock the bootloader..flash a custom kernel and then flash the ROM..thats all..ROM will be pre-rooted..

In my phone settings it says my phone is LT18i does this matter for anything?

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
http://unlockbootloader.sonymobile.com/
To unlock the bootloader?

Which ICS ROM Would you suggest? I just downloaded the Doom Kernel + Modules.
Thanks

I'm trying to flash the doomKernels boot.img in fastboot, I have put the ARC-DooMKernel-ICS-BETA-v04-lower-boot.img file in the platform-tools folder, I'm using the command fastboot flash boot ARC-DooMKernel-ICS-BETA-v04-lower-boot and it's saying it cannot load.
Any help please?
actually it says
'[ requirements ]
stock SE ICS Beta FW* (i havent tested on other ROMs so i cannot guarantee that it will work on them!)'
so I need to install stock firmware first?

You don't need to install superuser.zip. TWRP has a builtin rooting function.
After going to recovery for the first time and when you reboot, it will install su & superuser.

Lool i didn't get that on my mind! But to install root we need to turn the phone up then open SuperSU installer , so flashing superuser.zip maybe fastest and easyier!

The MIUI thread has a complete tutorial of how to unlock bootloader (okay you did that), but after that it explains you how to root and install CWM. What firmware are you on? From what I can see the instructions for how to root .200/.211 are a bit daft though (the author expects you to already have a custom recovery). If you're on .200 or .211, skip the rooting step and just flash one of the custom kernels with fastboot (for how to flash a kernel with fastboot, you can also use Flashtool to do this, see here: http://forum.xda-developers.com/showthread.php?t=1963961). Depending on which recovery you installed/tried to install, there are different ways of accessing it. If you used RecoverX, you need to tap the Sony logo a few times when you're rebooting. If you used a custom kernel or the 6.0.3.0 recovery for JB DooMLorD has posted, you need to press volume up when rebooting.
If we're to help you, we'd like a little more information. So what firmware are you currently using, which recovery were you trying to install?

1.Backed up my TA Partition
2.Flashed the official .569 ftf using flashtool
3.Unlocked my ZL's bootloader

FOR UNLOCKED BL

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

In your SDCard, simply delete the files in the XZDualRecovery or rename the XZDR.prop. If you delete them, they get recreated anyway and fixes that problem you had with 101

Oh, how much I love you right now. Thanks a lot! Will report if I encounter any issue with your files, though I seriously doubt I will.

Locked or unlocked BL isn't important with these files.
Just upload the ZIP to your SDCard and flash it in recovery, then power off your phone without rebooting and flash the stripped FTF with Flashtool and you're done.

Thank you guys!
But for those (like my self) who are not experts on this, could you please, provide a detailed (step by step) guide on how to flash it?
If I already flashed it to kitkat (not rooted), can I do it over this one?

If you already flashed 4.4.2 then you do not have root and therefore cannot flash these. You will need to flash back to an older 4.2.2 so you can root and then install recovery. Once you have recovery the steps are:
1 - upload the zip to your SDCard and flash it via recovery
2 - After flash is successful, turn off your phone without rebooting.
3 - Flash the stripped FTF file via FlashTool and boot your phone.
That's it
