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

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

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?
What is the important step must be taken before start flashing ?
Depends what your flashing
make sure u have GB version of flashtools in you want to flash GB or ICS version(v0,8 and above) if u want to flash ICS
make sure you have sufficient battery left
make sure you connect the phone is flash mode
make sure you have patience
you need adb and flashtool drivers installed download them from here....

If you want to root, then you have to downgrade to .58 or older firmware(lower than 58). If you want to unlock bootloader, then firmware doesn't matter, bootloader is not in the ROM.
If you unlock bootloader and you need root and recovery, you can install a custom kernel(most of them already include autoroot and recovery), your ROM gets automatically rooted and you already have recovery aswell.
I Should hold the BACK button before turning on handphone OR hold BACK button after turning on handphone and then connect OR just hold the BACK button without turning on phone?

Read guides.
Installation Steps (Warranty can be restored whenever you wish)
-------------------------
Before starting your rom flashing journey it is always better to have Flashtool (latest -by androxyde) installed in your PC and your stock rom handy ; incase of any mishappenings.
Type *#*#7378423#*#* in your phone and see if your bootloader status is unlockable under service-->Configuration. Procede with below steps, only if your device is unlockable.
It is important that you follow the steps in order
1) First step for installing a custom rom over a mobile with stock rom is to backup the existing state of bootloader .Usually warranty will get void if any modification is done to bootloader. The below tool ensures that it takes the backup of existing state of bootloader when device is under warranty.
Goto
Backup TA for Sony Xperia (This tool helps you to have a )
http://forum.xda-developers.com/showthread.php?t=2292598.
Download the tool.This tool will backup your DRM Securtiy keys . Successful backup can only be taken after the existing stock rom is rooted (Use towelroot application if your device is not already rooted) .Root it first then follow the process given in above link .
Once this is over , u will have a backup of the existing state of bootloader/TA partition (If you later wish to move back to stock rom from custom rom use the same tool to restore the backup you have just created.This means you will get your Warranty back);
2) Goto this website , follow the steps and get your unlock code via e mail.
Use fastboot mode to unlock your bootloader (Make sure that you have already backuped your existing DRM keys-Step 1).Follow it fully to unlock your bootloader
http://unlockbootloader.sonymobile.com/unlock/step1
3)Download any custom rom zips with recovery, for your mobile from xda developers forum and have fun.Extract boot.img using winrar or winzip .
Flash boot.img via fastboot mode
fastboot flash boot boot.img
fastboot reboot
4)As the device reboots, when you see your LED glow press volume up or down. It will take you to CWM Recovery or TWRP recovery based on the rom that you have downloaded.
5)Just install the custom rom(*.zip ) from within the recovery.
What if that i already have the custom recovery?
So, just wipe data, dalvik, and cache, then flash the zip?
That's it?

Absolutely right. But before installing an custom rom in the first place i hope you have already backed up your DRM keys for warranty purpose(as mentioned in the guide) since if you unlock your bootloader without backing up your DRM keys, DRM keys might be lost forever .

Sure. Easiest way to do it is by using an app called, 'Titanium Backup Pro'.But you have to root your stock rom first for this application to run(Use towelroot if you are yet to root).Except for sony proprietary apps like walkman,Album,etc (will run only on stock rom as they use sony developed system libraries/API'S) other apps will get restored/run fine on a custom rom.

its in the OP....on the phones dialpad, type: *#*#7378423#*#*
then look in > service > configuration
it should show the status as "bootloader locked", "bootloader unlocked", "bootloader unlockable" or "not unlockable" (sorry wording may not be exact, but you'll get the idea)

Sorry, did you type that in the phone and check the status? That's where it will tell you if its already unlocked or if its even unlockable at all.
Do not try to install a custom ROM on your phone if it is not unlocked! Your phone will not boot.

Thanks to @ foomanjackel for answering your questions.Regarding your 2nd question, 'Experience is the mother of invention'.Why don't you try and see what happens...just kidding.Couldn't resist it. Practically speaking of you install a custom rom with an custom kernel on a locked bootloader you will hard brick it.It will not boot and chances are that you might not be able to goto flashmode or fastbootmode anymoreto repair it.Reason this happens is that both your recovery and bootloader resides in the same partition in your mobile.If you try to install custom kernel on a locked bootloader in every probability, it not only corrupts your existing stocks kernel but also might corrupt your recovery leaving u helpless.
Theoretically, You should be able to install any custom-stock based rom on a locked bootloader (which runs exactly on ur stock kernel).In other words a custom rom which doesn't come up with a custom kernel but based on your existing stock kernel should be able to run on a locked bootloader.But my advice is you do not risk it.

If you get this message "Bootloader unlockable: yes" then your bootloader is still locked.

To use SUS, you must have a locked bootloader. For those who have an unlocked bootloader, just wait until someone uploads an FTF. FTFs can be flashed on unlocked bootloaders using Flashtool by Androxyde.

You can easily relock the bootloader in just two steps.
Flash only the kernel via flashtool and then relock the bootloader also via flashtool.
You can't go wrong if you've used flashtool before.

The process is quite simple but do it at your own risk..
Turn on your computer's internet..
Open flashtool and select flashmode..
Select the firmware, then exclude everything but kernel (Remember only kernel should be selected, exclude everything)..
Uncheck every option in wipe..
Flash the mobile, it should take just 4-5 seconds..
Don't restart yet, disconnect your mobile..
Open BLU option in flashtool..
Connect your mobile, a dialog box will open, just click on relock..
(Remember, don't turn off the internet connection untill the bootloader is locked)
Restart your phone, it'll still be rooted and you'll be able to get all official updates..
Only thing you'll lose is the cwm recovery..
Hi I am a newbie. I had rooted my phone using Towel-root method and am even using xposed framework and am running stock version. After this to Unlock my Bootloader I fallowed procedures as given by sony, but after i entered unlock command in cmd, my xpeira m went into bootloop.
I tried repaing usning pc companion it said that my mobile has been modified and cant repair, and hence using flashtool flashed stock xperia m rom and had to root again.
But the problem is that I still receive OTA updates from Sony for Walkman and album apps. If my booloader is unlocked I shouldn't be recieving those right ? How can I confirm for sure without flashing anything ?
Another question: Now If i flash CWM from here http://forum.xda-developers.com/xpe...ery-philz-touch-6-41-6-xm-dual-t2795778/page2 will that erase my rom ? I mean do I have to flash my stock rom and reroot after flashing CWM for my device to work ?
i think i have an answer

Hi raghu,
see answer to ur first question, i dont think bootloader status will effect ur updates , because at first i tried to install CWM and went into bootloop , before that i unlocked my bootloader using flashtool, so i flashed .ftf file and went back to stock , when i tried to flash CWM i noticed that my bootloader was still unlocked , flashing .ftf didnt change it at all. i dont know whether this happened to me accidentally or it will really doesnt effect ur bootloader status but the answer is bootloader status will not effect ur updats ( as far as i knw).
answer to ur 2nd question is no it wont erase ( i am sure about it :good ur current ROM, if u flash it right. Dont worry i tried that recovery before, its gud and flash carefully, dont end up into bootloop once again ..safe flashing
thnx :good::good:
Your device's bootloader is absolutely locked if you are still receiving the OTA updates (and installing ). And I would suggest you to check the Bootloader status in Flashtool.
No flashing the CWM will not affect your current ROM

hit thanks if this helps.:good::good::good:
hope this helps ,
As far as I am aware only the OTA firmware updates no longer work when you unlock your bootloader, the OTA application updates should work as intended.
For installing the kernel, all you have to do is put your device into fastboot mode, select the kernel with flashtool and then let flashtool work its magic. It won't wipe your ROM as it doesn't touch the /system partition.
You don't even need flashtool to check your bootloader unlock status either. Type in *#*#7378423#*#*, tap Service info, tap Configuration. You will see a section what says rooting status. Underneath rooting status you will find your bootloader status, it will read one of three things;
1) Bootloader unlock allowed: No (meaning you cannot unlock your bootloader, you shouldn't see this as you have unlocked yours by the sounds of the first post)
2) Bootloader unlock allowed: Yes (meaning you can unlock your bootloader, if it says this and you plan on unlocking the bootloader I hope you make backups of your TA partition cause you have no way of locking your bootloader again else. This goes for anybody reading this)
2) Bootloader unlock: Yes (meaning your bootloader is unlocked).
