[GUIDE FOR NOOBS] How to update Xperia S to Android 4.0 ICS: STEP by STEP

I have seen this question posted a dozen times today across several threads, thus, I decided to write a step-by-step, fool proof, noob-oriented simple guide; if somebody asks again please point him/her to this thread to avoid spamming the main discussion / development threads
STEP BY STEP GUIDE:
How to update the Sony Xperia S
to Android 4.0 Ice Cream Sandwich​
NOTICE 1: This guide is for WINDOWS PC USERS, if you have a Mac I can't help you, but the process is very similar
NOTICE 2: It doesn't matter if your phone is rooted or not, bootloader unlocked or not, IT DOESN'T MATTER, this update has nothing to do with SIM unlock, bootloader lock / unlock, root, etc
NOTICE 3: This guide will update your Xperia S from ANY previous version to OFFICIAL SONY ICS ANDROID 4.0.4 and believe me: it is worth the update; HAT TIP TO SONY !!
NOTICE 4: The internal SD card contents will NOT be deleted but everything else inside your phone will be reseted to factory defaults because this is a major update, so do a backup if you want to keep call logs, SMS etc. I only backup my SMS and Whatsapp messages, google backed up everything else because I had the backup option activated in settings
NOTICE 5: Before asking, please read the questions and answers in the thread for many Frequently Asked Questions

STEP 1:
Download the Flashtool
You will find the installers here: http://androxyde.github.com/Flashtool/
Go to the "installation" tab, download Flashtool installer v0.9.10.1 and run it
You will have a new folder on your PC: c:\Flashtool
STEP 2:
Download the ICS firmware update
You will find several download options here: http://forum.xda-developers.com/showthread.php?t=1723610, just pick one and download it, then come back here
SOME NOTICES (I know you are gonna ask):
- I know it is "Generic Switzerland" (CH) but nevermind: it is plain Sony Generic and works fine for any region and has ALL the languages and keyboards
-The firmware is already prepared to be flashed via Flashtool in .FTF format. If the file you downloaded is .RAR then it is compressed ("zipped") and you need to EXTRACT the .FTF with WinRAR (if you don't have WinRAR download it from here: http://www.rarlab.com/download.htm)
STEP 3:
Let's update the phone!
- Copy the firmware FTF file to c:\Flashtool\Firmwares
- Go to c:\Flashtool\Drivers and run "Flashtool-drivers.exe" to install the proper drivers for Xperia S
- After installing the USB drivers reboot your PC
- Go to c:\Flashtool and run "FlashTool" (if you have Windows 64 bits, run "FlashTool64")
- Click the flash button (yes: the thunder icon up left)
- Select "Flahsmode" and click "OK"
- Select the "LT26 6.1.A.0.452" firmware and click "OK", DON'T TOUCH ANYTHING ELSE
- Flashtool will prepare the files for flashing, just be patient
- A Window will pop up asking you to connect the phone in "Flashmode" showing instructions for an old Xperia phone: ignore it, here is how the Xperia S enters "Flashmode":
- Turn off the phone
- Press and hold the VOLUME DOWN key
- Keep it pressed, connect the USB cable to your PC
- Release the Volume Down key when phone's GREEN LED lights up
- Flashtool will start flashing automatically, let it finish to 100%
- Disconnect the USB cable when Flashtool reaches 100% and indicates flashing has finished giving some extra info about activating debugging mode etc (don't care, that's optional)
- Turn on your phone (press and hold the Power button for some seconds)
- The first boot takes some minutes, don't worry let your phone prepare your Ice Cream Sandwich for you
- Have fun !! :highfive:
PS1: PLEASE REMEMBER TO SAY "THANKS" to Bin4ry (for the FTF firmware) and Androxyde (for the Flashtool)
PS2: And the usual disclaimer, of course: Follow the steps and be careful, I am not responsible if you brick your phone, burn your house or blow your PC by following this guide; I am just sharing what I did to update my own phone :angel: and it worked for me

- Phone will have green LED indicating it is in "Flashmode"

- Flashtool takes a couple of minutes, let it finish to 100%
- Disconnect the USB cable

- Thefirst boot takes a while, dn't worry
- Have fun !!
PS: PLEASE REMEMBER TO SAY "THANKS" to Bin4ry (the guy who uploaded the firmware) and Androxyde (the guy who gave us the Flashtool)

1.- Nothing changes. This will only UPDATE the Android system, this will NOT SIM-unlock, unlock or relock bootloader, or root
2.- Yes: I sid ALL languages
3.- I don´t know (I never use it) but I guess yes you could (why not?)

We should take note of unchecking debugging mode in developments before using flashtool to upgrade if you do not want to meet several issues.

Sorry for this noob question, but
If i have a hong kong version xperia s, after flashing this Switzerland version, will it stay the same as a hong kong phone? Or it will be forever a Switzerland version? If there will be any OTA in the future, which ota update should i be expecting by that time, thank you in advance

1.- it will have switzerland version software of course, and you will be expecting OTAs from this software version, but I wouldn't recommend it
2.- you can always change your software with flashtool
but if you want to use official ways (OTA or PC Companion) then better keep the original software or reflash the original software
With flashtool you can flash this software today and return to your original software tomorrow (should an OTA appears in your region), you can change as many times as you wish

yes you can search for an already-made FTF of your software
or you can make your own with flashtool, search the forum for the how-to

Much appreciated!
And my last final question is, will this wipe out all user data and the apps? I didnt really see anything about these on the first post(If i missed any I apologize)
will the OTA/PC Companion do the same

Some users avoid wiping all user data but face issues afterwards
It ss always recommended to let the update wipe everything
PC Companion and OTA will wipe everything as well because that's the right way to make such a big update
I will add this to the guide tomorrow
PS: I use SMS backup and restore from google play to backup my SMS messages, and I backup my whatsapp messages from inside whatsapp (it has a backup option). Everything else (including settings, calls, apps, etc) is auto-restored by google

This can be helpful for anyone whose ROM isn't working. It is directed to noobs who accidentally ruins their custom ROM so they can start over. Also the reason why I'm doing this is because I searched the forums and I could not find a guide that was simple for noobs to understand, which would always work no matter what you did wrong. I've used this method so many times and it has saved me countless times. I thought the least I could do was to share.
I hope I answered your questions.

Why why why do People use uploaded.to links, and feel the need to rehost files to it. Just link directly to the flashtool and use mediafire for anything else.

I collected links from different guides/threads on youtube and xda and assembled them into this full guide. I did not bother to re-upload the files because I did not find it necessary though I agree, mediafire is really good. I will change flashtool link.

I understand this reply is far too late but for people in the future:
You cannot upgrade to ICS when your bootloader is unlocked. You can easily lock it again using this small FTF file. When the upgrade with PC companion is complete, you can continiue modifying your phone with custom ROMs etc.

It is very hard for me to know what is causing this problem. Some minor modifications to the flashing procedure can potentially fix it. Try doing it like this: Open FlashTool, drag the FTF-file and drop it in the dialog box. Press ok and wait for the instructions to pop up. When they do, connect the USB-cable FIRST to the phone and after that hold back key while plugging it to the computer. If the battery of the phone is too low I think it can cause problems, try to charge your battery (if possible) and try again. Also make sure to flash the appropriate FTF-file, accordning to your model.

rooting Xperia T is realy easy :
there is no problem if you are on 18.1.A.1.14. it's explained in Google...
if you are on 18.1.a.1.21 :
Flash only the kernel 18.1.a.1.14 with Flashtool.
start the phone and connected it to PC (even if the phone is blocked on "updating apps")
Root the phone with RootKitXperia (last version is 20140719)
shutdown the phone
Flash only the kernel 18.1.a.1.21 with Flashtool.
start the phone
run SuperSu and accept upgrade.
in order to well connect the phone to PC you need to allow debbug USB, and to put the scard in MSC mode

[Q] Restore Z1 Compact to stock firmware before sending it for warranty repair.. help

Hello XDA!
I've ran into some hardware related issues with my Z1 compact (the earphone jack is glitchy) and i want to send my phone in for repairs.
The thing is i have a modded cyanogenmod firmware on it as i preferred it over the stock rom. I also have that clockword mod thing.
As you can tell i'm not very accostumed to doing these things and i was wondering if anyone would guide me on how to restore the phone to its original stock setting?
The phone is a swedish device so i would need the scandinavian versions i'm guessing, any ideas out there?
Thanks.

You just need to find the right firmware for your region / provider.
I would recommend IaguCool's thread on Xperia Firmware Downloader & Checker, if you have flashtool installed you can make your own ftf that is exactly right for your phone. All the instructions are in the thread.
Hopefully you made a copy of your TA partition before you unlocked it and put CM on your phone? it may not matter if you have not, as long as it looks stock.

Hey digesteve,
Thanks, i'll check that tool out. I don't know if i made any backups of my TA partition, but probably no because i don't know about it.
Is there a way to see if i made a backup of the TA partition, could it be stored somewhere on the phone after installing clockwork mod?
Thanks for the help!

If you didn't do it, then it won't be saved anywhere on the phone. You have to physically copy it to the hard drive of your pc for safekeeping.
It doesn't matter, it won't stop you from restoring the stock rom and I don't think not having it voids the warranty. Maybe somebody could correct me on that?

Definitely didn't do it then. Hopefully they won't give me any trouble for rooting it, it's worth a shot anyway.
I've downloaded the firmware but it doesn't come in the same sort of package as cyanogenmod, are there any guides you can recommend on how to apply this firmware to the phone?

and don´t forget to relock the bootloader with flashtool!

You'll need a copy of flashtool and the adb drivers.
Flashtool will turn the downloaded files into a tft file, but all the instructions are in the thread.
If you get lost then XperienceD's AIO thread will guide you in the right direction

I downloaded flashtool from sonys website and it actually listed stock firmwares in a list which i could apply to my phone so i did.
Now the phone boots into what seems to the be stock firmware, however i was going to go into recovery just to check that was restored too and not the clockworkmod i had previously installed but it seems i cannot boot to recovery anymore, what can i do? Where can i find the "stock recovery" that these phones comes with? I want the phone to seem as it was never rooted/changed on the software level

Now the phone boots into what seems to the be stock firmware, however i was going to go into recovery just to check that was restored too and not the clockworkmod i had previously installed but it seems i cannot boot to recovery anymore, what can i do? Where can i find the "stock recovery" that these phones comes with? I want the phone to seem as it was never rooted/changed on the software level

You have flashed the Sony rom, so now it is stock, with no root or recovery. There isn't a stock recovery. Your work is done.

Isn't there a menu you can boot to that gives you the option to wipe cache partition and do some various other stuff? Perhaps this is only for samsung devices, sorry for the confusion and thanks for the help!
Hopefully the service goes as planned!

Is still the way to do it or is there any new ways ?? I have bought a Z1 Compact for my son who is 8 and he wants it back to stock. It has CyanogenMod now.....cant recall what version though since i dont have the phone with me.

From Samsung to Sony and confused about Bootloader unlocking.

Im thinking of buying a Z5P and while i have searched a lot, i just cant seem to find the answer to a question i have maybe someone here can help. On Sonys developer website there is instructions on how to unlock the bootloader and the last line of the instructions are as follows, note the part in blue text.
Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.[/B]
My question is how/where do i buy a Z5P that will definitely be Bootloader unlock allowed yes, surely its not just a case of random devices are unlockable is it? I was going to buy this from carphone its sim free so im expecting to be allowed to unlock the bootloader but dont want to buy it only to find i cant.

If the phone has no SIM lock, it's bootloader should be unlockable. I say "should" since I am not aware of other factors that keep the bootloader locked, but there might as well be.
On another note, unless you are a fairly advanced user and are set on flashing your device with a custom kernel, I would not recommend a bootloader unlock before root or an option to back up of TA becomes available.
It contains your device's DRM which gets irreversibly lost which makes your camera perform worse(BIONZ stops working), among other things.

CPW is the place to go for unlockable fones. I got my Z5P from there.

As mentioned elsewhere, IN GENERAL (rare exceptions) - if it's SIM-unlocked it'll be bootloader-unlockable. If it's SIM-locked, the bootloader is almost guaranteed to be perma-locked.
While SIM locks and bootloader locks are technolgically independent, in the case of Sony devices (This rule of thumb can NOT be applied to any other manufacturer), SIMlocked devices have a permanent bootloader lock, devices sold without a SIM lock can have bootloader unlocked. Note that in the case of phones sold with a SIM lock that are later unlocked with a PIN - the bootloader lock is still disallowed.

Cheese for the replys everyone I got the phone from the carphone and its boot loader unlock allowed yes
I got the regular z5 instead though.

Hey, Dunno if I have an option or not, but my phone says Bootloader Unlock Allowed: No.
I imagine that it's a no, but is there any way to unlock the BL? If not I may consider swapping the Z5P out for something else, dunno if I can live without root

Try flashing another firmware through flashtool that is allowed.

Worth a punt, didn't think about that. The only concern is that Flashtool isn't supported for the Z5p according to Sony's site.

As long as you use flashmode there is no need to be supported, because the program doesn't know which phone it is in that state. I flashed my Z5P once using flashtool about a week ago.

OK, cool, thanks.
Where do I get the firmware from for Flashtool? Can I flash something like AurRom using Flashtool?
Sorry for the idiot questions, but I haven't used Flashtool very much at all. Much more familiar with ODIN, ADB and flashing through recovery...

Install flashtool from "flashtool.net"
It comes bundled with Xperifirm where you can download ftf files for every Xperia device. You access Xperifirm through the Flashtool program.
You cannot flash AurROM through flashtool because it's not a ftf file. Flash a stock rom and try unlocking the Bootloader afterwards.
And don't worry about asking "stupid questions". This thread is made for every kind of questions, as long as it's about the device.

Thanks very much.
One final question, in the UK I have EE WiFi calling currently - if I install non-carrier specific firmware I will most likely lose this. Is there any way I can backup the existing software so I can revert whether the flashtool flash works or not?

What you want to do is follow sonys instructions on how to check if your phone is able to unlock bootloader here: http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
If you can unlock your bootloader, which you will know after performing the simple steps provided by sony, then you need to install android studio along with required drivers etc, before you can actually unlock the bootloader.
Android studio can be found here: http://developer.android.com/sdk/installing/index.html?pkg=studio
Read everything throughly, it is important to get all the details regarding usage and installation.
After installing Android studio, you should download all the required SDK's found inside android studio->Configure->SDK Manager.
On the left side you will see several options in the navigation menu.
First go to Appearance & Behavior->System settings->Android SDK. Then in the "window" you have, make sure the first tab is selected (SDK Platforms).
Here you need to check all the android versions your phone(s) run.
Then go to the second tab (SDK Tools) and download:
Android SDK Build Tools
Android SDK Tools 24.4.1
Android SDK Platform-Tools 23.1
Google USB Driver
Android NDK
I am not sure if you really need the NDK one, but the rest I think is required. You can do as I did and choose all if you want.
On the last tab (SDK Update Sites) I have checked everything.
When you have done all of this, you should install Flashtool and go to the install directory and open the Driver folder, where you will find a .exe file. Run this and click next untill you can choose a few items from a list, in this list you should check Fastboot drivers, and USB drivers, and any other options that are relevant to your use, then finish the installation. (The entire installation of Flashtool should be done with 100% admin rights on the user).
After this is done, connect your phone to your pc and go to device management on your pc and you will likely find something similar to this:
If you have this yellow exclamation mark triangle thingy, then you will need to manually install your USB drivers.
Download your driver here: http://developer.sonymobile.com/downloads/drivers/
Then right click the yellow exclamation mark triangle thingy device in device management, and select update driver, then select "Browse my computer for driver software".
On the next window, select "Let me pick from a list of device drivers on my computer".
In the list that appears, select "Show All Devices" and click next.
Click the "Have Disk" button, then navigate to the driver you downloaded, and you will get 3 options in the window on you screen, select "Android ADB Interface" and click next.
Confirm by pressing "Yes" Then press "Install".
If completed without problems you should see "Windows has successfully updated your driver software".
*NOTE* On the above steps, you can also navigate to the folder where you installed android studio, which should be something similar to this: C:\Program Files(x86)\Android\android-sdk\extras\google\usb_driver OR it can be found your USER folder.
and here you can install the usb_driver aswell, which should make most phones support USB debugging and ADB on via your pc.*NOTE*
now reconnect your phone and the exclamation mark triangle thingy should be gone, good!
Next thing you can do is navigate to the installation folder of Android studio, and go to the Platform-Tools folder.
Inside the folder, hold down shift, while right clicking any white empty space inside the folder, and click open terminal here.
In the terminal, type: "adb devices" /Without the " marks. then it should say something about daemon not running etc, when its done, do the same command again, and you should se you device listed. Good, at this point you are ready to unlock bootloader!
If you have succeeded in every step so far, then go ahead and unlock bootloader following sonys instructions!
When you are done, you can simply follow the guides provided in the custom Rom thread itself most of the time.
If not, then a simple way to do it is:
Get all the files you need for the rom flash. That means Kernel, rom img, and a custom recovery like TWRP and SuperSU.
It is REALLY important that all files are for your device specifically!
Put the SuperSU.zip and the custom Rom.zip on your sd card and put it in the phone.
To avoid any trouble, do as I did and save all those files in the Platform-Tools folder, because you need to open the terminal as shown earlier in the post, by holding shift and right clicking in the same folder as the files, this is a must.
Open the terminal from the same folder as the rom, kernel and recovery.
type:
Code:
fastboot flash boot NAMEOFYOUR_KERNEL.img (This is usually boot.img)
fastboot flash recovery NAMEOFYOUR_RECOVERY.img (Usually contains TWRP in name)
fastboot reboot
You should now press volume up key when a led lights up while you see the sony logo, a orange light, not the red one, this will bring you into recovery, from here choose install, then navigate to your SuperSU.zip and install it.
Reboot your phone and you are now rooted, if you also have a custom rom, then place it on your sd card like the SuperSU.zip, but make sure the custom rom is a ZIP file!
Boot into recovery and install the custom rom, wipe cache and dalvick cache.
Congratulations on your custom rom!
Hope this helps a bit, sorry for any errors, but this is exactly how I did it, as far as I can remember!
Btw, this can seem like alot of work, especially when and if you encounter any problems while installing. I know I did encounter ALOT of them, but hopefully with my simple guide you can avoid them!
Luckily, this is just something you have to do once if you do it 100% right!

The problem he has is that his stock ROM (or the phone itself) doesn't allow bootloader unlocking, probably because of SIM and carrier lock. Therefore he first needs to find a way to make the phone unlockable.

I am no expert on this, but doesnt the carrier decide if its locked or not?
I've seen people solve it by flashing different and unbranded firmware, but not for this particular phone tho, but I dont think it's officially possible.

At this point he could at least try, he's got nothing to lose. I have never had this problem, because I buy my phones unlocked no carrier involved, so these are only suggestions.

Yeah, what I would try is first just try to do a full restore of your phone via PC Companion, and if that doesnt work then id try downloading an unbranded firmware from XperiFirm (If I am not mistaken, those named CUSTOM or something are unbranded) and then flash that via flashtool and see if that works, if not then your last hope is to get it replaced by warranty, which I'd say is fraud if the device isnt actually malfunctioning.

I don't think PC Companion works at all, because the only thing it does is downloading identical firmware like the one on the phone. So Flashtool only choice.
I replaced mine with one from flashtool that has a lot less bloatware it originally came with.
