[Q] bootloop major problem

hello there
i have changed my rom and now i want to go back to my stock. i tried to use pc companion to restore the phone but when i did i got a message saying that i don't have the official rom (or something like that) and that i can not restore my phone to original. so i tryed to change my rom to the stock manually. but i dont know what .ftf file should i use. i made a try with one and now the phone bootloops and i can not even go to cwm to restore it from there.
please please please help me i am so lost.

You have to use flashtool to flash a stock ftf to your phone. There are some here Any one of them would do.
The one i use is here

the thing is that i have arc s and i am in greece. i guess i just need the official ftf file to flash throu flashtool but i just cant find it anywhere. if anyone knows please share a link.

greek official ics ftf is here

thanks man. i am downloading it right now. i just flashed an ftf file "LT18i_4.1.B.0.587_Kernel" and its still bootlooping, i just dont understand why is this hapenning.
+ am i ever gonna be able to use pc companion again anyway? i mean to update my os

i think the problem is you are flashing a kernal instead of a full rom.
also you'll be able to use PC companion and all it's functions when you have a stock rom

[Q] How does one revert one's Xperia S back to stock ICS from Cyanogenmod 10?

I'm asking because I specifically flashed another boot.img for Cyanogenmod 10.
Now, what are the exact steps I need to take to go back to stock ICS?
Do I need to flash a stock boot.img first, with fastboot or something, and then flash a stock ICS zip from ClockWorkMod?
I'm not really experienced with any of this, I've flashed only about 3 times but none of which required me to install a different boot.img (isn't that the kernel file?).
Any help would be amazing!

I always follow 2 steps in CWM
1.Flash advanced stock kernel and reboot.
2.Flash stock zip Rom.

Can this advanced stock kernel be flashed from within CWM as well as the ROM? I used something I believe was called fastboot for it.
And the kernel is indeed the boot.img then?

If you want to go back to stock, dont flash anything..
Now reverting back to stock is much easier as sony has released an official flashtool, just download the tool and latest firmware and flash it using the tool..
Once again dont flash any kernel or any rom if you want to completely go back to
stock.

Yep sure There are 2 versions of advanced stock kernel. One is flashed via fastboot and another one is flashed via CWM.
Then, on CM, Pac, Para which Rom are not based on stock one, boot.img is exactly the kernel

I tried this, but I couldn't get the official flash tool from Sony to work.
I apparently had to have a company when making an account to log in. Very odd.
I assumed this other flashtool made by probably xda developers did the same thing, but that one always gives me an error that I need to install the drivers first. Yet I've used this program before and back then I already went through all the hassle to install the correct drivers.
And now I don't know which drivers to install anymore.

You need to follow the instructions in sony's developer website for installing the flash tool..
Did you install the drivers using the drivers folder in flashtool??
And does your phone get recognized by the flashtool, I mean does it show your android version etc etc..??

Thanks A LOT!
Sony's beta flashtool, Emma, works like a CHARM!
I initially forgot to copy the customisation file from the zip to the installation folder. Thanks for reminding me to check the instructions
The unofficial flashtool couldn't recognise my phone, but Sony's one could.
Thanks so much for answering my questions, I'm starting to learn how it all works! If I could, I'd give you 10 thanks. But I think that's against the rules c:

It won't.
My bootloader is still unlocked, though my root is gone and everything else is back to normal.

My goal is to flash a new firmware on my xperia s and have it rooted.
I am not quite sure which steps i need to take in which order to do that. I would be very greatfull if someone could tell me the steps i have to take.
I will look for the guides here but i need to know what when to do.
I can unlock my bootloader, and i'm running a .55 version.

First of all don't panic!
Grab any .55 firmware and install it with FlashTool, when installation is finished don't turn on the phone, disconnect it and hold Volume UP button so it boots in Fastboot mode, then in FlashTool click FLASH then select fastboot and press Flash Kernel > flash this one (Download) When it's over just turn on your device as normal and you will have .55 with Root & Recovery. Good Luck
BEFORE INSTALLING KERNEL UNRAR THE PACKAGE YOU NEED ONLY .elf File.
Just Select elite.elf when choosing kernel to flash.
Attached KERNEL is by RaymanFX.

Thank your for the quick answer.
Do i first need to unlock my bootloarder?
Which firmwares can i install with that kernel?

Hello @schpongo,
I'd Certainly Help You Out.
First of AlL, What You Need Is
1. Unlocked Bootloader - http://unlockbootloader.sonymobile.com/
2. Rooted Device - http://forum.xda-developers.com/showthread.php?t=2133063
3. Installing CWM Recovery. I prefer RecoverX - http://forum.xda-developers.com/showthread.php?t=1773227
And As My Friend In Above Post Said. Do Not Panic. It Takes Patience. And lots of waiting time.
Till one process is complete do not try to unplug or close anything. Its easy when you do things very calmly.
Ok Now for Available ROMS - http://forum.xda-developers.com/showthread.php?t=1950706
If you require suggestions regarding flashing roms I'd advice you to start with TEAM FXP ROMS - Cyanogen Mod 10

I Solved the Problem partly by using the flash tool to get back the stock os.

You can use the Flash tool to flash the boot.img file in the phone. It's really simple then manually doing it. I am on phone so can not provide you the link. Please use the search button on how to flash boot. Img using flash tool. Looping in boot is because the boot.img was not flashed properly. Use the flash tool to do it. I too had the same problem when I first flashed but soon found out the problem. Reply back if everything works..

CM 10 is a really good Rom with Stable recovery.
You can even download other ROMS of Build NOZOMI - (Code Name For Xperia S) eg Slim Bean build 5 Nozomi JB 4.2.2
And directly flash it from CWM recovery.

Yes, Unfortunately For This Purpose There is A Need for a little knowledge of Titanium Back Up.
It Will Bring All Your Settings Messages And Apps Back Without Any Modifications. Or loosing it.
The Reason : Every Time You Flash A New Rom
You Always ,
1 Whip Cache Partition
2 Cache /data /sysytem
3 Dalvik Cache
This Removes All The Apps.

then follow the steps shown by the flashtool program/exe
during the flashing progress(just wait)
(this method can also be used if ur phone i bricked/soft,hard)

Press thank if i help^^

If you still have problems with Flashtool, use PC Companion instead. The steps are easier for users who are not sure about using Flashtool or Emma.
Also, please post in correct section next time. This is General section. Questions go to Q&A section.

You're using the outdated root method. You need to follow this http://forum.xda-developers.com/gal...l/how-to-root-lp-5-1-1-supersu-2-6-1-t3266010
Basically, you need to reflash stock rom then follow the directions.
