Hi just wondering if anybody knows how to debrand the 3 UK Xperia Arc S. I have de-branded an Xperia Play before but I cannot find the approriate files for the Arc S. Any help would be appreciated. 
Thanks

First of all, you should ALWAYS post your doubts in the Q&A forum.
To debrand the phones flash with flashtool any generic firmware, here you have 4.0.4 firmware for the ARC S : http://forum.xda-developers.com/showthread.php?t=1583010
Sorry I am new to XDA and thnak you too i appreciate the help
Once installed and debranded.
look for how to root once you got this you can get rid of all the bloatware that is installed.

Yeah I will do but I have read that currently there's now way to root the 4.0.4 update yet for xperia arc s when i had the Play i used one click root.
Yes , you can root 4.0.4.
You have to flash 4.0.4 ftf, after that you have to flash 4.0.3 kernel ( you have to download 4.0.3 ftf and flash just kernel with flashtools).
After you have your arc/arc s with 4.0.4 rom and 4.0.3 kernel , you use the one click method for the 4.0.3.
After you just need to flash 4.0.4 kernel and you have a full 4.0.4 (rom+kernel) rooted

Hey guys! As the title states, Just trying to figure out a step-by-step way to upgrade my Arc to 4.0+ whilst having a LOCKED BOOTLOADER.
I am unable to unlock the bootloader and understand this causes quite a few problems.
I already "bricked" the phone once..had to repair it to get it back to stock again. I don't want to go through that again..
So, it would be greatly appreciated if someone could kindly direct me to, or outline here, a step-by-step guide to installing ICS on my Xperia Arc.
Thanks for all your time and help!
Use flashtool to flash the official ICS release.

Hey thanks for the quick reply. Do I need to have root before upgrading? And also, do I need CWM recovery?
Can I just use flashtool to flash the ftf file?
Thanks again for the help. Much appreciated

Just flash using flashtool, it flashes the kernel too. I think Binary has added a root file too.

There is an update you need to apply to flashtools if you have version .6 you need version .7 look in stickies for flashtools... Info in that thread.

If your phone is Xperia Arc(LT 15i) I recommend you to wait the official update of ICS for arc, at this moment ICS is available for Arc S. I have Xperia Arc but i use a custom ICS rom with custom kernel, and bootloader unlocked.
Thanks everyone for the info.
My Xperia is LT15a, but I recently got it repaired and now it says LT18a instead. =S
Android 2.3.4
Baseband: 8x55A-AAABQOAZM-203028D-64
Kernel: 2.6.32.9-perf - [email protected] #1
Build Number: 4.0.2.A.0.62
Bootloader is Locked
Can I still upgrade?
Thanks again for your time and help!

huh ? i do not understand... is it okay for the repair shop to do that ? . . . there are several h/w differences between last year's model and this year's model to 'require' the new internal s/w to properly talk to the new h/w ( drivers... )
.
please correct me if i am wrong.
Can I inctall ICS on my xperia play with 2.3.2 (rooted locked bootloader)? Some websites say you have to have android 2.3.4 (latest update) in order to do so. Thanks

I wanna say that you would need an ICS kernel , which you would need to unlock your BL for.. and the system on your phone wont matter, since ICS isn't official on our plays your will need to instal a custom Rom which will overwrite everything anyway
Thanks

But if I am installing an official ics Rom (released by Sony Ericsson) would I have to do that too?

Well I did some reading and I think you will need an unlocked BL and at least be on the .42 firmware, 2.3.4 like you originally posted. I know there are a few ICS roms that work in the developer section. But I think for the official beta release your gonna wanna follow what Sony said.
Edit: looks like you have to fastboot a boot.img and userdata.img and system.img

You'll be able to get ICS without an unlocked bootloader once the official update is released, since the official releases can be made into files for flashtool.
Aside from the fact it'll be done through SEUS.

if you want to try the stock ICS then you need to flash a 4.0.4 firmware with the help of a software called flashtool..there are many guides which will help you.

Flash stock firmware like. 50 or. 45 using flashtool in flashmode.This is absolutely safe.Then root & flash cwm.After then flash kernel & baseband of. 55 and flash. 55 rom in cwm.
Press Thanks

Will it not work how they're rooting the new U firmware? Just use flashtool to flash kernel only of the older firmware. Root with binary, then use flashtool to flash kernel only of the latest firmware again?

and what about the warranty? and i heard that flashing down/downgrading is only possible when you have a unlocked bootlader
you can use flashtool even if youre on locked bootloader.
Flashtool is fine for warranty etc as it's only flashing official sony files

1. Get it from Here
2. Yes, sure.
3. ICS17 is the modified stock kernel added more features than stock one
Hold on.......
If you've flashed the ics17 kernel then you've unlocked the bootloader yes?
Then scrap off any ics rom and flash Jellybean

I need official Sony 's rom.
I see. Then flashing the 55 ftf would be best. How come you must have Sony only?
