by XB on 21st June 2012

in Android, Featured Content, Firmware, Tips & Tricks, Xperia S

Sony Mobile stuck to its word and has today released Android 4.0.4 Ice Cream Sandwich to Xperia S owners. This is the first 2012 Xperia handset to be updated to Android 4.0 and finally fulfils the potential of the handset that first hit the market in March 2012. As with all Xperia updates it can be a painful process waiting for your particular country/carrier version to be available. However, if you don’t mind taking matters into your own hands then you can download the update today.

The FTF file of the Generic Swiss update (SI: 1257-3740] has just been released. The update will upgrade your firmware build to 6.1.A.0.452 as expected and kernel version 3.0.8. We’ve detailed previously how you can use the FTF file and FlashTool to flash this stock firmware safely onto your handset. Get all of the necessary download links and instructions below.

Xperia S Android 4.0.4 download links


For FlashTool, download and install the v0.8.0.0 full version, before you apply the v0.8.6.0 update.

FlashTool Windows Edition – v0.8.0.0
Update: Windows Edition – v0.8.6.0

Generic Swiss ICS Xperia S firmware

Download the Generic Swiss ICS Xperia S firmware from here (335MB) and extract the files using WinRar. This is firmware version 6.1.A.0.452 which will update your Xperia S to Android 4.0.4.

FlashTool Guide

We previously outlined how Sony Xperia arc S owners could update to Android 4.0 ICS. The principles for the Xperia S remain the same – just make sure you download the above files and then follow the same instructions here.


  • The linked tutorial does not require you to root your Sony Xperia S and it does not require you to unlock your bootloader.
  • We recommend that you backup your Sony Xperia S before flashing and do a full wipe when installing the new ICS firmware. This will not delete any media (pictures, music and video) on the phone. See the settings to be used on the FlashTool image below.
  • You need to press and hold the volume down key while plugging the USB cable into your Xperia S.

      Does it break the warranty ?

    • Thank you so much! Downloading now!

    • minur

      thank you:)

    • Will this erase data stored in my phone such as camera photos, videos, etc?

    • Ahmad Ghazzawi

      amazing !! luv this blog and love sony and for sure love XDA

    • DarkElement

      Same questions as above + the following: Can i change the language to Dutch?

    • fried_egg

      will be interesting to see how long orange UK take to update and what they add/remove from standard

    • loms

      no. people from XDA who have flashed it confirmed that their files were not wiped out. Good thing is, you dont need to have your phone rooted or bootloader open. :)

    • Thanks loms.. Cant wait for the download to finish!.. :P

    • Strong_Brother

      I’m gonna try to updae to ICS soon, but before I do i’ll need to hear some positive feedback first.

    • mario

      it’s a stock firmware.. no one will know you’ll flash it yourself :) so no it doesnt break your warranty

    • Aokde Gharra

      in some countries/carriers yes. in some carriers any change in the OS will void your warranty

    • diena @

      My phone will lose all data if I use this guide to upgrade my Xperia S

    • Thanks guys. Now I can updated my phone to ICS. Just press volume down button, you can update your XperiaS. Dont press back button. I was in Indonesia.

    • jimmy

      Guys is that true? i cant find out how to do an folder on homescreen xd on gingerbread it was possible ,what about here? have somebody find it how?

    • abhi

      when i try to open camera, it says camera not available. anyone else facing this issue after the update?

    • Sandi

      right – pull it out and turn it on with an extra long push on power on…

    • sandi

      My pics is still on the phone after the flash…

    • dawid

      its 15 minutes phone didn’t reboot. What’s wrong?

    • Aokde Gharra

      you will lose nothing. you can still use PC Companion and SEUS. one case you might get errors with PCC or SEUS is when you unlock your bottloader, and you’re not unlocking it by flashing a firmware.

    • M Usman

      really? you may have bricked your phone. Don’t worry. Reflash it again

    • M Usman

      no. camera works fine

    • M Usman

      drag one icon over another and let it go. then it will give you the option of creating a folder…

    • M Usman

      so are mine. I backed them up anyway but nothing got deleted. of course the settings and installed apps did. but everything on internal storage stayed

    • M Usman

      no its not slow. i downloaded flashtool in 2 minutes. and the ftf file in 5 mins. I guess lots of people downloading at once and a crap internet connection may have caused it to be slow for you

    • M Usman

      there is not physical back button on the Xperia S LOL

    • M Usman

      5 minutes max

    • hexly

      it keeps telling me the debugging mode is not on when it is, can anyone help?

    • hexly

      when trying to flash it says that debugging mode is of when it actually is on, can anyone help?

    • Freakanil

      Hey……. I just tried, but my phone doesnt boot up after flashing is finished. Now what do i do???? Can anyone help me please…….

    • Haroon

      How did you root your xperia s with the above ice cream sandwich? I have looked online but cant find a tutorial on how to do it

    • hexly

      when trying to flash it says that debugging mode is of when it actually is on, can anyone help?

    • what about mac users?

    • Polarized

      Hate to say it but……underwhelmed

    • Is it me or everybody’s lockscreen is ‘no more’..I dont know what happened but i get directly to my home screen when i press the power button..If i dont have a password, that is..But there’s no slide to unlock thingy anymore :(

    • dattofuboi

      damn never been so easy whip in and whip it out

    • CaptainCS

      Follow this youtube guide: for backing up your existing firmware. You can flash back to stock and shouldn’t have any warranty issues. Or can then upgrade to ICS through your existing carrier.

    • herro

      Does anyone know how to take a screenshot? There used to be an option when you held the power button, but it disappeared after the ics update.

    • George

      Mine kept crashing! Go into Settings and clear cache for both Walkman Apps that appear. It worked for me!

    • Rene

      Power Button & Volume Down Button at the same time

    • HELP

      Does updating to ICS root your phone when doing the above procedure? I just want to know because it voids your warranty, and i already updated my xperia.

    • Chhunleng

      Can you tell me the link how to root it.

    • Ash

      Volume down

    • Ash

      nice one…. installed and changed language to english… for UK/IE users: you will be asked during initial setup for language option, so no problem to do that without any german language knowledge.
      you can disble now facebook and twitter scum….

    • JenH

      will this update available through OTA??

    • Ash

      AFAIK yes

    • Ash

      no, no rooting, no bootloader changes

    • JenH

      :) I’ll wait then….. thanks

    • AlmightyBong

      I don’t seem to be seeing Performance Assistant anywhere…

    • mike

      erm.. you can go to settings >> security. the options should be there. It’s probably ticked as none, and for ICS, there’s the new option of face recogniton. The default in the original 2.3.7 of XS is the slide lock option.

    • Praveen Kavoor

      thank you started downloading….

    • avery

      Hi! I just need to know…. if I want to return to my actual update (FW .75) can I do it? Thanks in advance!

    • Cheng

      Have big question I need your guys help for: Im currently on 2.3.7 on my Xperia S. Rooted.

      Now my big problem is, can I upgrade to 4.0 WITHOUT losing data? or any upgrade will lose all my data? the fact is I have a LOT of things (60+ games, 70+ apps) on my phone. I dont wanna actually backup all of them…costs me too much time, and the more I am afraid I might lose stuff due to incompatibility…… what do you guys advise? I dont wanna actually risk my current nice phone status and content for only 4.0 upgrade. If it clears all my stuff again, I rather wait for my next phone to use 4.0….what do you guys advise? thnx in advance.~~

    • What i can tell you, yes you will lose everything !!! Unless photos and music files that are on the 32g memory all the rest will go ! Better backup !

    • Cheng

      most of my games and saves and apps are on internal memory (that 32g), those are safe? I still will lose alot from “phone only” I guess..sigh

    • firmware file corrupted..?? help

      Thanks, so it doesn’t void your warranty. Thank god. But how do i go back to stock. Do i have to bring it to customer service to revert it back to Gingerbread. Please anyone Reply !!!!!!

    • AlmightyBong

      Do you mean Face Unlock? Mine does.

    • AlmightyBong

      Sweet! Warranty intact!
      That said, if this can be done without rooting or unlocking bootloader, what’s the purpose of rooting and unlocking bootloaders in the first place?

    • AlmightyBong

      The Face Unlock is awkward and funny for me… I’m not used to seeing my face on the screen before it unlocks. I can’t stop giggling. Back to slide to unlock… Hehehe!

    • AlmightyBong

      Mine didn’t reboot by itself as well. Just power on as usual, and wait till the phone vibrates or the Sony logo comes up. If nothing comes up, reflash as advised.

    • AlmightyBong

      Hmmm… I didn’t notice at all that it is a specific German version. After flashing my phone with the FTF file, the phone actually detected I’m in the Philippines and gave me a selection of language that I can use during the first time setup. I selected English (Philippines). Then everything else is understandably in English. Don’t see no Germans anywhere on my phone.

    • AlmightyBong

      Sony PH? Philippines?

    • dax0330

      yes it really works great! battery life has improved a lot with ICS! the built-in task killer is quite handy ;)

    • HELP

      Well, I’m not an expert on this, but from my point, i think if you unlocked the boot-loader, you can do what ever you want with the phone without being restricted. I don’t know if this is right but yea :)

    • Cheeky Raffy

      I thought this ICS update is only available through PC companion”?”

    • Cheeky Raffy

      I believe if you do that you’ll loose your warranty.

    • HELP

      Yes, I know if you unlock your boot loader you’ll lose your warranty. What happens if you don’t unlock the bootloader and not root the phone is it still under warranty? What should I say to customer service to flash it back to stock version of andriod?

    • Sanal_Ry

      Hello everyone. I am wonder at LT26i and LT26, what is the different between them? In the picture the model number is LT26i but in the firmware download is LT26. Please leave a comment here. Thx u in advance.

    • Rune Christiansen

      I would just find someone with a PC, or wait for it to be released officially where you live, cheers :)

    • Rune Christiansen

      There’s lots of little good things in it. Few things I’m a little disappointed with is that it’s less smooth than GB, music is not really stable(poweramp) -it can hiccup when browsing at the same time no matter priority you set it to and it often unloads the home screen making it load up slowly when exiting an app.
      If anyone else have a solution for these , please reply.

    • JenH

      just checked the pc companion… saying i’m using the newest version (Taiwan user)

    • naveendas99

      Unbelievably smooth and user friendly

    • Strongful_Brother

      Anybody having problems installing JuiceDefender after ICS update? Goes to install then just reboots the phone instead. Tried different methods as per Latedroid’s website inc. Beta version but still same issue. Battery is awful without it! Btw, it’s a UK version.

    • Alvinator

      I installed the ICS on my Xperia S and I´m thinking seriously to downgrade.

      I´m getting a lot of lags just sliding between home screens (with only 3 widgets), when I´m playing ‘Cut the rope’ the game simply exits without any alert, the wi-fi signal looks weaker, the phone is overheating when using an animated wallpaper and a lot of apps (gmail, facebook, foursquare) are freezing all the time (I need to wait about 20 seconds to get a response from the touch screen or buttons). =(

      Everyone saying it runs smoother than ever and on my phone it doesn’t happen.

    • please resolve the lags…i downgrade to GB ch1

    • Hey i found a Huge Problem in this firmware is that when i connect my xperia s to the computer it shows me that xperia s is connected bt it is not showing me the files like music, photos, etc… bt the ics works reallly great and awesome everything became better except the problem i mentioned above please try 2 fix it … and Thanks 4 this upgrade :)

    • Hahahaha.

    • WindyMiller

      Hi All, My Xperia S is currently rooted, if I update using this method does my root remain rooted?

    • Lythanhlong

      Just root your phone. Back up programs into titanium backup, back up sms with sms backup app and backup contacts on sim card. Then just drag all those files into computer. Flash this new rom then paste it back into phone. Done.

    • hey guys after ICS update my phone is little bit laggy as, gng from one screen to another the screen widgets are appearing slowly,,does any one having the same prblm and is there any solution???

      I updated without backing up and everything was there afterwards, files and apps. I think the backup is one of the steps you go through before the phone updates. I don’t about the rooting though
