You have to unlock fastboot on your phone. Flash a custom kernel and rom. Take your pick

First unlock bootloader, n find the ics rom u want from the play dev forum, u can choose from many different roms based on ics beta or else the ics beta itself

Locked Bootloader

You'll need to unlock your bootloader bro. If your Xperia is a debranded phone (bought directly from Sony) you can unlock it for free.
If you're under a carrier company, you need to check the following:
In your dialer, please put this code: *#*#7378423#*#* and if you made it corretly, it will display the service menu.
Go to Service info-configuration
Go down and see the Rooting status.
If "Bootloader unlock is allowed" says "Yes", congratulations, you can unlock your bootloader for free; otherwise you'll need to pay about $25 to unlock it. In the process your phone will be SIM free, so you can put any carrier SIM if you want.
This is the official site instructions:

¡Good luck!

Once you've got all the bootloader/rooting stuff figured out, I recommend XDarkICS ROM. It has extensive gamepad/touchpad support and is based off of Sony Stock ICS. Almost no bugs. Use DoomLord's ICS beta V3 kernel if you choose this ROM.

I would say that rom is quite buggy going by comments but definitely a must rom for touchpads

Fast Xperia Arc Kernel

Hi All,
I have a rooted ICS Arc (4.1.B.0.431) with a locked bootloader. What is a good, fast kernel for it ? Thanks in advance.

Call me silly, but you the entire benefit of unlocking your bootloader is the ability to flash custom kernels. Therefore...locked bootloader means no custom kernel.
I'm no guru....so please, anyone, correct me if I'm wrong here...

I am unable to update to FW.587 OTA. The update center downloads the update and fails to update upon reboot (get an error here). I suppose my only option due to this is to flash the official .587 kernel. If I need to flash a kernel, why not a 'better' kernel ?

Then U Flash A FTF ,
Because For ME OTA Sucks !

Don't upgrade to .587. Lags too much, I went back to .431.
Kernel-wise, unlock your bootloader then try ArcKnight 3.5.1 or SEGA Kernel V3 Army edition.

[Q] Unlocked Bootloader and Rooting

Hi, I am new to Android and rooting and had a couple questions. I will be getting the Xperia Play R800x soon. If you get the bootloader unlocked from SE, do you still need to root the device? I have been trying to get everything ready for when I get the phone. I have Android SDK and Flashtool installed. If I want to get the NXT Light Edition Rom, do I need a custom kernel as well? Thanks.

If you get your bootloader unlocked and flash a custom kernel/ROM no you dont need to root as nearly all, if not all come with root. Seen as you have flashtool and everything else use a custom kernel. If you want to return to stock then just reflash a ftf file for r800x , make sure you dont flash a ftf for r800i though. I dont have the link handy but there is a thread here with all ftf files. Just search in XdA

Just a heads up.... The NXT light rom is gsm... It won't work on the r800x
Sent from my R800x

Thank you Wedgess and Lordomn. Since the NXT light is for the GSM version, would you recommend the COLA rom, or maybe SlimBean or CM9?

Think CosmicDans MIUI for ICS is for cdma. Id say its probably one of the best performance wise for ICS. You could also check out my PACMan ROM gor JB i uploaded a cdma version which works fine touchpads are also supported, camera/video ect works. Also instead of saying thanks click the thanks button instead

slim bean performs very well also.

Came back to GB 2.3.7

Yesterday I flashed on my Xperia S GB 6.0.A.3.76 FW. after testing a lot of roms like CM9.1/CM10/KA Xperia/Stock ICS and much more ,I understood that the perfomance with GB FW is the best ever... Everything works like charm ,camera is really great ,especially with "[MOD][CAM]GBXperia S|Video 1080p >20mb Bitrate|720p >15mb Bitrate|>100% Image quality".
Gaming perfomance is so smooth... no lags at all ,GTA VC works and it really great. Also Mobile Bravia Engine is a very huge advantage to me!
Waiting now for the official JB release from Sony ,till then I'm staying with GingerBread FW.
:good:

I thought bravia engine is not working to those who already unlocked bootloader even if you relocked it..yup I agree very smooth when you in gb because I try to reflashed it to recover the drm keys but im failed..music download info is not working also bravia engine..try stock based rom, try xtx7 so smooth also for me it is the best stock based rom and I modify it gx home preferences and tab&grid, all this mod and rom was created by niaboc..see attached

My BL is unlocked and I didn't relocked it. BE works well on GB FW ,but not on ICS. Also tried XTX7 ,but the perfomance was to much sluggish ,games worked on a very low FPS.

One question: If I relock bootloader I can use PCC to update my phone without bricking it right?

I have unlocked bootloader on custom ics rom and my MBE is not working, does relocking bootloader and switching back to gingerbread will make MBE to work again ?
My MBE was working perfectly on ICS before unlocking my phone's bootloader.

It should work. I also had Locked BL with ICS .452 FW and MBE worked great... After unlocking BL ,MBE never worked for me on ICS ,even on .452 FW. Now I'm on GB and unlocked BL.

Never actually tried GB on my S, as soon as I bought it I updated to ICS. I'll give GB a shot and see how it is

Ok, so I need to download the zip file then extract the ftf file and put it inside the flashtool firmware folders then flash through flash tool. After that I can also use fast boot to flash Doom Kernel for root. Ok, Got it. Thanks!

I successfully downgraded my xperia s and MBE is also working,my bootloader is also unlocked.
What if I relock my bootloader and flashed ICS 6.1.a.2.45, will MBE work?

or update it OTA?

is there root for 2.3.7? I was thinking of switching back to Gb too before but not sure if it can be rooted thats why im with ICS for now.

tried rooting gingerbread but kept bootlooping, one more try and it looks like it might have to be going back to ICS.

[Q] Ion says Bootloader Unlock Allowed: No, Can I install custom ROMs/kernels anyway?

I've been trying to buy a Sony Xperia Ion (LT28AT) for use on T-Mobile USA where the bootloader is allowed to be unlocked. So far, all the devices I've looked at all say No.
I know I can still root an LT28AT where the bootloader unlock allowed = No, but I can't install custom ROMs and kernels, right?
But from reading threads here it seems some people can still install custom ROMs and kernels where the answer is No. Can anyone please clear this up for me?
Thanks!

With a locked bootloader you can use roms that are stock-based.
With an unlocked bootloader you can use roms that need another kernel, just like miui, cm 10 etc

Does that include CyanogenMod ROMs like CM10, CM11 etc?
Also, with a locked bootloader can anyone tell me if I can install any kernels that will overclock?
THANKS!

CyanogenMod Roms need their own kernel, and to flash this kernel, you need an unlocked bootloader.
You cant flash any custom kernel on a locked bootloader.

You must unlocked bootloader before flash another kernel.

So what ROMs are stock-based that are available on XDA?

U can actually flash cm 10 on u a locked boot loader... A developer @mrgeez is working on making cm10 rom for locked bootloaders... Some roms work on locked boot loader and some don't... But ideally don't buy a cell with locked bootloader.. Causes to many problems..

What's inaccurate about it? This is an exception because they managed to get CM10 working with a stock kernel. You can't get any higher versions though because those require an appropriate kernel that isn't stock anymore. There have been a lot of kernel changes between Android 4.1 and 4.2. So on locked bootloader you can install stockbased ROMs (like eXistenZ) and one particular version of CM10. Impossible to flash a custom kernel.
Unlocking the bootloader also has downsides though. Beyond Android 4.0, the Mobile Bravia Engine stops working on an unlocked bootloader. Without that, the colours are a bit more washed out, and the screen already isn't the most vibrant around (the Xperia S screen anyway, but the Xperia Ion screen isn't that different).

So really a locked bootloader means I can't install any kernels, And I can only install ROMs compatible with my existing stock kernel.
