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..

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

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?

CWM for Xperia S/Acro HD

here's a quick and very easy guide on how to install CWM on Xperia 2012 line ups.
just download the CWM install file
SO-03D / Acro S here
Xperia S here (big props to PuriketsuAngel)
unzip folder
connect phone normally via USB to your PC
go to unzipped folder, execute install.bat
that's it, CWM installed.
to go to recovery mode - just restart device (turn off, turn on) and while on the SE logo, simply tap the screen of your phone several times.
up and down volume keys will serve as your directional keys, camera button will serve as "select/ok" key.
and yep, back and home buttons work within the CWM environment.
note: when you choose to restart/reboot system now while on CWM screen, phone will turn off.(it does on mine). just restart normally - like pressing on the power button to turn it on.
Device must be rooted. we got a tut on how to root your device even on locked BL here
N O T E
This is a work around if restoring from previous back up is giving you error.
Back up :
Before doing a NAND back up - please do a manual reset of your device - no additional Apps must be installed. Also clear/delete any left over folders from your SD card.
Restart device then tap screen several times - once in CWM - clear cache/dalvik cache.
Then and only here would you do a back up for your ROM.
Restore :
Before doing a restore - please do a manual reset of your device - turn device off, hold vol-up and power button at the same time until you get 3 vibrates.
Now you can do restore.
if this CWM version is still giving you errors : please provide a detailed account of the error message, a logcat will be appreciated.

Good to hear. But I will wait for someone to confirm this. Kinda scared (I had another device, and modded it a lot, but I'm quite noob to XS yet)

nothing to be scared about. the guide is fairly easy to follow and no special key combination required. the process just installs CWM on your recovery partition.

Ok. I think I will do it. But you will buy me another one if this one bricks (JK... )
EDIT: It was easier than i thought. Thanks, it works
EDIT 2: Home and back buttons work

so, with this now we can install modded roms?

If they use stock kernel, yes.

Good point... let's hope someone find a way to unlock the BL or start making cool roms for stock kernel
EDIT:
Som questions regarding this:
- If we reflash the firmware, we lose cwm?
if not, I know we lose root, but with cwm can we root again?
PS: somehow now I have a backup I feel safer xD

Strange Problem With ARC LT15i.

I was installing Custom Rom to Stocked LT15i with (Bootloader Status Allowed = YES) phone And i faced a strange problem that I never faced before. Below is detail of my problem
1. I Installed Stock 4.0.4 Stock ICS Firmware Via Flashtool before it was on same 4.0.4 but its was updated via PCC.
2. I Try to unlock its bootloader from official site i got the key and try to unlock but Fastboot command said its already unlocked bootloader. So I head to next step.
3. I rooted it with Prerooted kernel image. name ARC Autoroot v1 its worked fine.
4. I installed ClockWorkMod Recovery 5.0.2.7-nAa-r2 via batch command provided but a user in this section. worked fine.
5. Now Problem is Any Custom rom i want to install from CWM its give me (satus 7) eroor. I preceded steps 1 to 5 again n again but same error.
6. I tried all the solution for Error status 7 provided by user but no luck. like build.prop and removing some script.
one thing i noticed its IMEI start with 01 m not sure it is the cause. Let me know what is the easiest way to install custom rom to it. Its belong to my friend.
(I am able to flash any kernel )
I search all the night but didn't find solution so i ask.

Not sure what you've been searching for - status 7 error xperia arc

You need to flash compatible kernel for the custom ROM you are trying to flash.For example, when you download CM10 ROM, kernel boot.img is included in that rom zip. First we install compatilbe kernel(boot.img in case of CM10) and install rom zip from CWM.
Download and install CM 10 just to make sure you are doing it right.But first flash kernel first.

I have done but when i flash the kernel i m unable to boot in recovery but stuck on sony logo. or kernel logo. Then again i flash stock rom to run it again. This is the first time I m facing such problem I have tried many phone and succeeded but don't know what is problem i have changed SD Card thought its make problem but no. Tried LT18i Rom same issue, MIUI+ Kernel, Cynogen + Kernel, Pac + recommend Kernel, Other + Kernel. I can't say its Internal Memory Problem coz i can flash stock smoothly.
And when i flash Cynogenmod Kernel its CWM not let me use SD Card say can't found SD card.
Anyone recommend me the following steps which worked for you
1. Stock (I have only recommend me version)
2. Root Method give me link
3. Recovery or kernel Give me link
4. ROM JellyBean LInk .
Thanks.

Sounds like you're using the wrong command then. The right one is fastboot flash boot nameofkernel.img

[Q] Trying to install Xperia Play Z final version, very confused. (r800a)

Hey guys, as the post title says, I'm trying to install the xperia play z rom, and I'm hitting a lot of road blocks. First one is, I don't even know if my phone's bootloader is unlocked! I'm pretty sure it is, because I thought all r800a's came with an unlocked bootloader, and I also used the flashtool, unlock bootloader tool, and it said it was already unlocked.
So, naturally what I do, is I flash the firmware in the guide (located here - http://www.android-hilfe.de/root-cu...a-play/417392-rom-xperia-play-z-v1-1-0-a.html), and after that I want to root it so I can install a recovery. But when I try to root it, it always fails on part 1. So I tried to install cyanogenmod recovery without it. But after the apk is installed, i'm not able to install the actual recovery because it is not rooted.
My main problem with the guide is that it says to just boot into clockworkmod recovery, but I don't know how to. I turn on the phone and press the up button, but without installing the CWM/X-parts recovery, there's no way I can expect it to come up.
Any help please? I'm totally lost here. I know how to get roms that are based on gingerbread, but for some reason, Ics/Jellybean roms don't work at all, and I don't know if it is whether because my phones bootloader isn't unlocked (even though it says it is), or it's something else, like me missing a tutorial specifically for ics/jellybean roms.
Thanks in advance.

Well you have to flash an ICS kernel first and it will already have a cwm recovery in it. Then you can just boot to recovery and flash the rom

OHHHHHHHHH. Thank you so much. But how am I supposed to flash the boot.img for the modified doomkernel v3, which it says it includes in the guide? Am I supposed to extract it from the rom zip or something? Thanks again.

yes, boot.img is inside the zip. Unpack just that file and flash it with flashtool (in fastboot mode). But you must have unlocked bootloader to be able to flash any custom kernel

Sorry, another question. What happens is that when I try to flash an ics kernel, it goes into an infinite bootloop, but when I flash a gingerbread kernel, it works fine. Is this a sign of a locked bootloader? Cause I thought you wouldn't be able to install any kernels if it was locked.

If you flash ics kernel, you won't be able to boot your old gb rom. Ics kernel only boot into ics rom.
When you flash ics kernel, go to recovery and install ics rom.

Thank you so much. Worked like a charm.
For future readers -
a. The r800a indeed does come with bootloader unlocked
b. It is normal for the phone to bootloop, Just go into recovery like normal and install the rom .zip. (It's usually tapping back while starting the phone, but if that doesn't work, try up volume or down volume)

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?
