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?

no tats just model number for arc s...
follow the method..
unlock
flash custom kernel
flash ROM
u r done!

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

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?

'[ 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?

Update Arc S to latest ICS stock ROM

Hi guys!
I have an Arc S (Lt18i) stuck on Gingerbread and I would like to have the latest stock ICS version, which I think is 4.0.4.
I understand I have to use a program called flashtool.
Will I be able to flash the ROM using flashtool if my phone isn't rooted and the bootloader is locked?
And could someone point me to a link to download the ROM?
Thank you very much.

No you cant flash kernels whrn your bootloader is locked...
You must unlock & root your mobile 1st.
You can only flash firmware(ftf) files with above configuration...

Locked bootloader can flash stock kernel, you cannot flash custom kernel. Locked bootloader does not mean cannot flash kernel.

Ok thank you very much! so I've looked and just to clarify:
I put this file in the "firmwares" folder in c:\flashtool,
press the lightning icon and choose Flashmode,
select Wipe User Data,Wipe Cache and No Final Verification Check
Will I loose all my apps? and if so, can I do it without wiping user data?

Flashing via Flashtool will always wipe data. Unless you have a nandroid backup, it's not possible to keep apps and their data.

Wrong. Flashtool does not require unlock or root to flash stock firmware/kernel or any other part of the FTF file.

[Q] Point me in the right direction?

I recently got the Xperia S {No SD Card Slot, 32gb internal Storage}
I know it may sound silly, but could someone point me in the right direction for Flashing and Rooting this, what what's the best Rom/Kernal/Recovery Menu for this awesome device?
Just want to say, I do have experience on flashing stuff, installing roms ect
Just wondering what tools are needed to Root and Flash this thing
Thanks All!

this is the xS index for tutorials and guides and everything in between
regarding the part about best rom, you're always gonna receive a biased opinion on that coz that pretty much boils down to user preference

Check first: *#*#SERVICE#*#* >>service info>>configuration
if it says Bootloader unlocked allowed=yes then try as explained below ! It will definitely works !
I suggest you to first unlock your bootloader via the easy tool described at here http://forum.xda-developers.com/show....php?t=1560613
then flash the Doomkernel with the flashtool booting at fastboot mode. Before doing that never forget to install the necessary drivers.
The kernel is preloaded with custom recovery CWM and TWRP. While booting when you see doom logo pressing at 'vol +' you'll get CWM and pressing at camera button you'll get TWRP.
And flash the su and busybox package via recovery (CWM or TWRP)
for flashtool http://androxyde.github.io/
for kernel and su & busybox package: http://forum.xda-developers.com/show....php?t=2305591
& then enjoy Rooted jelly bean

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
