unfortunately I can not because I can not get into fastboot mode

But you can access to recovery right??
Than install doom kernel v1a from recovery there is a zip file in the original thread.

I had the same problem when trying to install a custom ROM (forget which one) the phone was stuck in a boot loop and I couldn't switch it off to get it into fastboot or recovery no matter what I did, then I managed to get it to switch off by holding the power off and volume up buttons together, the phone will vibrate once then about a second or so later it'll vibrate 3 times and force a shut down, I think it's like a hard reset feature, then you should be able to get back into fastboot mode from there like normal, hope that has answered your question and I'm not just talking crap.

Phone stuck in boot loop.

My phone is stuck in some kind of a boot loop... i can get it into download mode but cant get it into cwm. I have tried flashing lots of stuff via odin but it doesn't make any difference. Is there any way I can fix this?
weird O.O do you mean bootanimation is looping cause you can actually get into CWM before the bootanimation
nope clockwork mod has disappeared D:
After installing new ROM did u again wiped cache or data?? If so reinstalling would be better,,
I reinstalled using odin

By flashing via Odin with a stock rom, you'll loose CWM. You have to flash CWM again to get it back. But as you described it, you can't even get into Recovery mode (blue Samsung recovery screen with HOME+Power button combo)?
^^
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If u can't get to recovery mod then flash a new firmware from sammobile via Odin

I had this problem also.
I reloaded a new stock rom from sam and loaded it with odin, after the install I turned the phone on with the power button + the home button and did a factory reset and wipe catch.
And that worked.
u need to hold the power button + home button till you get in the menu.
I came from cm7.1 and went to stock rom 2.3.5.
Hope get it. Otherwise post your steps from which rom you came.

when the phone is showing samsung, you can release the power button, but keep hold the home button until recovery menu showed

I think this recovery.img was not walid... I did that with my phone too, and nothing appear in screen. U have to flash another kernel (i suggest, the doomlords kernel). After that turn on the phone, and press the volume up, when doomlord logo appears.
hope it helps.
How are you getting on is your phone back on?

If you tried the methods above with no joy it obviously isn't installed. With the cwm you are trying is there a .bat file in the download on your computer. If so while your phone is plugged into PC run the bat file and follow onscreen instructions. Then try launching cwm again.If you havnt managed it yet leave a message and I'll find it.

I am posting here as I am facing the same problem.
I have been following this guide to flash my phone with CM10 from ICS stock rom.
h#ttp#://androidlegend.com/xperia-s-update-to-android-4-1-jelly-bean-with-cyanogenmod-10/
I have successfully followed everything done previously, including Unlocking the bootloader, getting root access, installing busybox, using RecoverX to install CWM.
I copied the FXP150-cm-10.1-20121209-UNOFFICIAL-mint.zip to sdcard, is it this that is required to flash to ROM or the boot.img that is inside the zip?
And I am stuck on that part where I have to reboot into recovery mode. I have tried
a) Connecting my phone and opening fastboot mode and then try to keep the vol up pressed to open recovery mode.
b) Without connecting, powering my phone on and pressing volume up. But there is no blue LED
c) Without connecting, powering my phone on and continuously tapping on sony logo. After that Xperia logo.
But I can not enter the recovery mode.
A little guidance please?
Flashing CM needed a seperate kernel. Keep following the instructions to use fastboot to flash the boot.img
Power the phone off. Hold vol + then plug the USB cable in. There should be a blue light.
Poorly written tutorial IMO. Should be flashing kernel first then the rom to save some panic.
I asked the Sony-Support, they say that there is no recovery-mode.(for Xperia U, but they are the "same")

Guys, dont ask Sony cause stock ROM doesnt have recovery.
If you want to flash CM you must fastboot the boot.img inside the zip file, before that put the ROM into your phone memory, power on the phone and keep pressing vol up, enter into CM recovery and flash rom from phone memory. Wipe before and after.
Agree, stock ROM doesn't have Recovery Mode. When you turn your phone with VOL_UP, nothing happens :cyclops:

try flashing it again, maybe your first flash had an error.
Met the same problem and here what I did:
-Take off the battery in 10 minutes and put it back
-Plug the charger into the phone and do the logging in CWM steps (press and hold the volumme up, press the power button).
Finally it worked, hope this can help

HELP - Xperia S stuck in boot logo

My Xperia S is just a week old with locked bootloader.
I rooted it and backed it up thru CWM.
I applied a sound mod thru CWM which i did not like so tried to flash back my backup.
Before flashing i wiped everything possible, cache, data, system, dalvik cache, battey stats.
When i tried to flash my backup the recovery says there is ' MD5 Mismatch '
So now my Xperia S is stuck at boot logo, does not go into recovery, does not go into flash mode so i'm not able to flash thru flashtool or seus.
I tried holding Power and Vol Up button , but it only restarts the mobile and again stuck at boot logo.
Pls help i'm losing hopes.
Thanks in advance.
Have you tried turning the phone off, hold vol up and connecting USB and see if you can get it into fastboot mode?

ok dont panic, hold POWER + VOLUME UP and when it vibrates release the buttons. Boot the phone. If its still stuck than hold POWER + VOLUME UP for 20 seconds and repair the phone with seus since its with locked bootloader. If that doesnt work, download firmware around this forum and flash the phone

Anyways, Got my Xperia S back . The service center people just had to charge for a day and flash the back the stock rom . I still dont get it how did they get the device into flash mode.
Another thing i learnt is that from sept 16 all sony ericsson service centers will be shut down and the customers have to go to sony showrooms for repairs or replacements here in india.
Thanks Everyone , topic closed for me.

Bad Recovery
I'm thinking I completely ****ed up my phone, but someone please prove me wrong.
I flashed the ROM but it got stuck on the bootloading screen. So I rebooted into CWM and did a SYSTEM restore.
Problem is, I restored the system to when it did not have CWM flashed yet.
So now, it boots into the custom bootloading image and stays there. When I hold power+volume to reboot into CWM, it loads the original bootloading image (as expected) and gets stuck there because (I'm guessing?) I did not do a full restore.

If you have locked bootloader, repair it via SUS or PC Companion. If you an unlocked bootloader flash the rom (ftf) via flashtool.

Charge your phone. You have to press and hold the volume up and power button simultaneously until the phone vibrates 3 times and turns off completely. Then try to connect the phone in flashmode.

Adb Acess at boot?

Is there any way to access adb during boot? I want to be able to clear the cache on my phone, because i recently restored to the stock software. But there's one problem, when i repaired my screen, i nicked the volume control ribbon cable, and i've lost my volume buttons. So using the home/power/volume up combo won't work for me.
Any suggestions/ideas?
I have a usb jig to get me into download mode, so i have the ability to use odin, is there an odin package that i can flash that will just clear the cache/and do a factory data reset?
Can anyone steer me in the right direction? I just need adb access at boot, or a flashable odin file that will only do a factory wipe
Change csc...if you change csc it will duo factory reset.
Send form Galaxy S2. But I don't have it :-\
I thought you could boot into recovery using fastboot which would have adb access

I thought he could boot the phone since his power button is working.
Anyway, I tried it on my phone. I shut it down and powered it on. As soon as the boot animation started the device was detected by the command
"adb devices"
Then I just used
"adb reboot recovery"
and it immediately rebooted (mid way through boot animation) into recovery.
I hope this clears things up.

Thanks for the reply, i've tried this But for some reason when i do the adb devices command it only says " a list of devices attatched" and no device id.
I'm in a boot loop right now, and my computer does recognize the connection to the phone, maybe the adb drivers aren't installed properly?

I tried that, still stuck in a boot loop Oh well I've ordered another ribbon cable and volume buttons for my phone.
I can't think of anything other than trying to flash stock ROM using Odin or better a pre-rooted ROM which hopefully will boot normally and also give you reboot into recovery in power menu...

I did try to flash back to stock, as well as partitioning the phone with odin, but it still seems to just bootloop. Any time i've flashed back to stock firmware i had go into recovery and do a factory wipe, and the phone booted right up. But when i replaced the screen in my phone, i tore the volume ribbon cable. So no easy way into recovery
If you change csc then flash and modem and pda like jb leaked

Partitioning? Maybe you screwed up something when you did that... besides after flashing stock you don't need to clear cache. It must boot properly because flashing stock ROM will clear your cache anyways...

TUTORIAL STARTS HERE*
1. Enter Download mode by holding both volume rockers and inserting a USB cable while still holding
2. Get to the screen that asks you if continue with Download Mode or not.
3. Remove USB cable and click the 2nd option.
4. Phone will restart and that's how you turn on a phone with no power button.*
Is this how you get into download mode? Anyway that's how you may be able to boot too.
Well and if you can't boot cause of softbrick you simply should flash another rom via Odin. Once there you can access recovery with restart tile in many actual roms I think. Otherwise you can use rom manager to boot into recovery or other apps. There are many possibilities.
