Steps to take Stock -> Flashed firmware - Sony Xperia S, Acro S, Ion

I am kinda new to rooting and flashing so i am in need of some assistance.
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

What do i do now i did a backup before using cwm but if i try to restore it says " Error while flashing boot image!".

Help

not just anybody

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.

CWM for Xperia S/Acro HD

here's a quick and very easy guide on how to install CWM on Xperia 2012 line ups.
just download the CWM install file
SO-03D / Acro S here
Xperia S here (big props to PuriketsuAngel)
unzip folder
connect phone normally via USB to your PC
go to unzipped folder, execute install.bat
that's it, CWM installed.
to go to recovery mode - just restart device (turn off, turn on) and while on the SE logo, simply tap the screen of your phone several times.
up and down volume keys will serve as your directional keys, camera button will serve as "select/ok" key.
and yep, back and home buttons work within the CWM environment.
note: when you choose to restart/reboot system now while on CWM screen, phone will turn off.(it does on mine). just restart normally - like pressing on the power button to turn it on.
Device must be rooted. we got a tut on how to root your device even on locked BL here
N O T E
This is a work around if restoring from previous back up is giving you error.
Back up :
Before doing a NAND back up - please do a manual reset of your device - no additional Apps must be installed. Also clear/delete any left over folders from your SD card.
Restart device then tap screen several times - once in CWM - clear cache/dalvik cache.
Then and only here would you do a back up for your ROM.
Restore :
Before doing a restore - please do a manual reset of your device - turn device off, hold vol-up and power button at the same time until you get 3 vibrates.
Now you can do restore.
if this CWM version is still giving you errors : please provide a detailed account of the error message, a logcat will be appreciated.

Good to hear. But I will wait for someone to confirm this. Kinda scared (I had another device, and modded it a lot, but I'm quite noob to XS yet)
nothing to be scared about. the guide is fairly easy to follow and no special key combination required. the process just installs CWM on your recovery partition.

If they use stock kernel, yes.
Good point... let's hope someone find a way to unlock the BL or start making cool roms for stock kernel
EDIT:
Som questions regarding this:
- If we reflash the firmware, we lose cwm?
if not, I know we lose root, but with cwm can we root again?
PS: somehow now I have a backup I feel safer xD

[SOLVED]Need urgent help! Device stucked on black screen...

Oh man not again... I've lost my previous phone (TG-01) in the same way. My phone was working just fine until I decided to flash the turbo kernel (http://forum.xda-developers.com/showthread.php?t=1817548). By following the directions in the link (http://www.xperiagamer.com/Beginners-Guides/how-to-use-fastboot.html), I've done all of the steps mentioned but then the problems started. When I first opened the device after flashing the kernel, all I saw was just a black screen. Approximately two minutes later the battery indicator and clock showed up on the top right of the screen. With some search in Google, I've found the post below:

So I've tried to follow these steps too but looks like I'm failed. Now I can't flash another kernel because the PC doesn't detect my phone after the "waiting for device" prompt in the fastboot. Before trying something again I thought asking for help in the forums is a good idea. So please, please help me. I'm very upset now and I won't get any better without fixing this problem. Any help is appreciated. Thanks in advance.

Did you flash the recovery on xperia gamer site?If you did this it is only a recovery not a kernal.You should have flashed a kernal with recovery built in like the turbo kernal which as recovery built in.According to xperiargamer gamer link you need to to connect through flashtool to get into the recovery.I would look in flashtool to try to boot into recovery or flash another kernal with recovery built in then flash a new rom.But obviously flashtool needs to recognise your phone :fingers-crossed:
That's the problem. Before I messed with the settings it had no problems with detecting my device. I guess I screwed up something.
Also just noticed I CAN get incoming calls but I can't answer them. So the phone is actually working, then? What should I do now?
What rom are you on?Can you get in fastboot mode with phone?(holding search while connecting to pc.) is the phone partially working?

When I first flashed the kernel I was on stock 2.3.4, but immediately after the flashing I switched to X Dark ICS. Yes, I can use the fastboot mode, but fastboot does not recognize it while SEUS does. Weird...,
I can enter the boot menu with no problems at all.
Xdark ICS is not compatible with turbo kernel.Only certain roms work they are listed on CosmicDan site.Also when you say you can get into boot menu do you mean via the phone?

Yes, I can enter and browse the boot menu by opening the phone while tapping back and volume up keys. Now trying on a different computer, will post the results.
No use. Damn.
PLEASE HELP ME BEFORE I GO NUTS.
Confused by what you mean boot menu! Do you mean recovery? Also if this is turbo recovery just install a compatible rom via install zip option,there are links to them on CosmicDans site.Download one place on sdcard and flash with turbo recovery :fingers-crossed:
Re: Need urgent help! Device stucked on black screen...
Boot menu?? Recovery?? Cant u just flash a stock firmware via flashtool using flashmode?? If the boot menu you were talking about is recovery u should be able to enter fastboot/flashmode. Regarding the un-recognize problem did u try updating the driver?? Does flashtool even detect your phone??
Sorry for the lot of Q. Just want to get a clear view of your situation.

No need to apologize, you are right, I should have mentioned these.
Flashtool? I don't think it's Flashtool. It's something in the fastboot folder with the command prompt thing. Shift+Right Click if I remember it correctly.
Trying the Flashtool now, I'll keep you updated. Thanks for the reply.

Guess what?.I've flashed version 4.0.2.A.0.42 (UK Generic) with Flashtool. And now my phone is back again! HAHAHAHAHA I'M FRICKING HAPPY!!! THANK YOU GUYS. Ehm... Really, I thank you both. You two have a good day.
By the way, what should I do now? I was thinking about installing some Custom ROMs but I'm too scared to do it after these. Now the phone's running on 2.3.3. Is my rooted/bootloader unlocked status gone?
Congrats. Flashtool is a perfect fail sav. As for root, just use flashtool to root it. BL stays unlock once u've unlocked it. It locks when u decide to lock it. Everythings there man.

Did you actually install a Rom
@OP or did you just flash the turbo kernel? @everyone else If you flash a new kernel would that necessarily delete your ROM or would you still be able to boot to a stock rom?

[Q] Need help installing Jellybean on my Arc S

Dear all,
Firstly, I'm new to this forum - hi. I have done an extensive search and found some guides but even those confuse me so I'd appreciated some constructive comments without any links to guides I may also find difficult.
I'm trying to install Jellybean to my device using a guide (that I currently can't link to because I haven't had 10 posts).
I have downloaded the two zip files it says I need (ROM and Google Apps) and have copied them to my SD card. However I don't know how to get into recovery mode to then load these. I downloaded RecoverX and tried to install it but it says my phone is either not connecting or is missing some drivers. I have busybox installed and my phone is connected with USB debugging enabled.
Can anyone advise me further?
Thank you.
What have you got?? Unlocked or Locked Bootloader ???
You forgot the first step.
Unlocking your bootloader
You have to unlock bootloader to flash custom jelly bean kernel. Then you can load cwm

Restore backup, its only thing u can do right now. If u want to flash custom JB rom, u must unlock bootloader as said before because different versions of Android cant run on the same kernel.
To install custom rom, do this steps:
1) unlock bootloader (if possible, otherwise, u r stuck with ICS roms.)
http://unlockbootloader.sonymobile.com/instructions
2) After that, its simple - flash selected kernel via flashtool and then flash desired ROM!
And piece of advice, u have search on this forum, its quite usefull

Of course you can still use flashtool
You should flash back to stock Rom again and root again
If you want to use jelly bean, you have to unlock your bootloaderfirst

For that you have to flash via CWM the Google Apps or the so-called Gapps. Link: http://goo.im/gapps/gapps-jb-20121011-signed.zip (If you flashed the 4.1.2 official SlimBean). I help you because that's the ROM I use (but the 4.1.2 version, not the 4.2.2 by besttt)

Something weird happened.I clicked on the BLU button on flashtool and it says my device is still unlocked. After unlocking using flash tool I am now able to flash CWM and TWRP. But both recoveries still would not let me install the roms I mentioned earlier. It still thinks that I'm on another device. Currently downloading CM11 from the CM website. Waiting for my download to finish. But I have a feeling it still wouldn't work. btw, thanks for going through step by step with me. I'm still new to xperia devices. Owned an s plus last time and the whole rom flashing process wasn't really hard like this one.lol
EDIT: UPDATE!!! I have finally found the reason for my problem. I flashed an incorrect version of the boot.img.Because I dump all the stuff related to flashing rom and I dont really remember the location in which I downloaded the boot.img. So what I did was I extracted the whole content of the rom that I downloaded proceed to flash the boot.img using flashtool. from there on, everything works perfectly! thanks for your help. Without ur suggestion, I wouldn't have tought of manually getting the boot.img!

[Q] Unlocking bootloader

Hi everyone, I have an Xperia Acro S and recently I wanted to unlock my bootloader to get acces installing custom ROMs, now I've a question about unlocking the bootloader, I have read/seen many tutorials/videos where explain the official way to unlock the bootloader, in all of them say that I need to provide the IMEI to the Sony web, so I can get an unlock code; the IMEI has 15 digits, but I've seen only first 14 digits it's needed, today I used the entire 15 digits, got an unlocked code, but I don't know if I'm in the right way, or I need to ask for another code using just the first 14 digits.
I hope anyone could help me.
Thanks in advance.

Nah You are doing right, only first 14 digits are shown online since it is not safe to publish own imei on internet. Since You received an unlock code, it is safe to assume that You are going the correct way.

So, you're telling me that It's ok I provided the entire 15 digits to the web, and got an unlock code, so I can continue the procedure and unlock my bootloader? This just scare me, because I don't want to make unusable my device. Thanks for your reply.

Yes, as long as You provide it on the Sony website, it is safe to do the procedure. And don't worry, it won't make Your device un usable.

Do as per the instructions given by darknessmc, just an addition that clean only cache and dalvik immediately after You flash the ROM.
Thank you both, I finally got what I wanted, finally got a ROM on my device, actually was very scary, because the TWRP was in chinesse, I've got a hearthattack when I saw the symbols. :S:S:S
But Google translator and another guides helped me out. :good:
Hi guys, I've a question, if I want to install ahother ROM, do I just follow the steps you gave me before? I mean, that step when I need to enter in fastboot mode and flash the boot.img. Thanks @Mirhawk @darknessmc

Hello, how have you been? Mr. I have another question about all this, flashing with FLASHTOOL is the same as flashing with the recovery? If i want to flash a new ROM and in its instructions says I need to flash it using the flashtool, do I just follow your previous steps or I need to install the flashtool? thanks

Hello, If you flashing a stock rom you use flashtool but if it's a custom rom your phone has to be rooted. Please follow the steps to root and etc.
"If you come from a stock Sony firmware image please flash this kernel before via fastboot:
Quote:
Attention: your bootloader need to be unlocked to flash a custom rom like SlimBean.....a good step by step tutorial you find here:
http://androidlegend.com/how-to-unlo...peria-s-lt26i/
after that you can go ahead with the next steps below
1. Download:
(Kernel or if the rom has a boot.img file that will work)
2. Turn your phone off and hold the volume up button and plug in your USB connection and wait till the LED is getting blue
3. Terminal command to flash:
fastboot flash boot boot.img
4. Reboot your phone and wait till your LED turns violett....in this moment push the volume up button and you have access to your custom recovery
5. Connect your phone with USB and push the downloaded roms and gapps to your phone now with the terminal command:
adb push <filename> /sdcard/
6. Wipe data/cache/dalvic, format system, flash the rom and the gapps and you are finished "
The end. Good luck Please have you custom ready on hand. Download SMS backup app to backup your sms's, root not need for this. Your apps should download on it's own after a few minutes when the phone is on and working.
Happy modding.

No, flashing with flashtool and recovery is different.
Flashtool : You can only flash stock firmware(the .ftf files) or kernel (.img , .elf etc) using flashtool.
Recovery : The recovery is used to flash the ROM and kernel's in zip format, they cannot flash .ftf files. Also they can't flash files if they are not in zip.
If You are going to use a stock based ROM(i.e. JB ROM's) then some Developers need You to flash the Stock firmware(ftf file) first and then flash their ROM. So You flash the stock firmware(ftf) via flashtool and then flash the ROM after installing a recovery.
If You are going to flash a Kitkat ROM, then simply follow the earlier steps.
