Use the Q&A section, we have it for a reason. But to answer your question, you hold the lower volume button down.

Sorry if I posted in a wrong place but when I press power + volume down key the phone boots normally.
Should USB debugging mode be connected?

i dont know if it should be on...but it would not hurt to try.
also. For flashmode,
turn device off--->insert micro usb into phone while the regular usb is not in computer----> before inserting normal usb, hold the volume down button and then insert

Thank you!
I will try and post it.

[Q] Bricked Sony Xperia S - Help a noob out!

Hi all,
The wi-fi connectivity on my Sony Xperia S died a few days ago and it's been irritating me so I decided to root and upgrade to JB to see if that would sort it. Unlocked the bootloader, no problem. Rooted the phone, no problem. But then CWM couldn't identify my device and wouldn't install Recovery. I decided installed Flashtool and flashed a stock kernel, and now it seems like I have bricked the phone.
When I boot I get the Sony splash, and the Fastboot (blue) LED which then goes out leaving just the Sony splash. Pressing the volume keys does nothing during Fastboot. I can do a hard reset and get the three vibrations, but the boot loop is just the same when I power on again. In this state Flashtool says the following:
1/039/2013 14:39:48 - INFO - Device connected in flash mode
11/040/2013 14:40:32 - INFO - Device disconnected
11/040/2013 14:40:37 - ERROR - Drivers need to be installed for connected device.
11/040/2013 14:40:37 - ERROR - You can find them in the drivers folder of Flashtool.
Naturally trying to install the drivers does nothing.
Anyone got any suggestions? I really don't want to have to fork out for a new phone!
Cheers.

Make sure you have closed PCC & SUS.
Then try to flash again.

As cities516 has said, first make sure that all those Sony services and update programs are completely shut (be sure to check the status bar near the time and date too). When you power on your phone, the blue led blinks for some time and then fades away. This blue led does not indicate that you are in fastboot mode. So here is what you must do:-
1) Press and hold the volume up + power button until you get 3 vibrations.
2) DO NOT START THE PHONE.
3) Prepare flashtool to flash the stock ics ftf file
4) When it prompts you to connect your phone, hold the volume down key and connect the USB cable.
5) A green led should light up and the flashing process should begin.
6) Once the flashing is complete, disconnect the phone and turn it on normally.

That's great stuff, thanks. All working now! Although I do feel like a moron, I hadn't realised that the PCC was open in the system tray!

[HARD BRICK] can't get in CWM or turn off sony xperia S LT26i

Hello guys, I have a Xperia S LT26i in the Italian official version of software 6.1.a.2.55 rooted by E-Root v1.0.14 ( locked bootloader )
i wiped battery stats (after wiping data...cache ...all what we can wipe, mount and unmount every thing from the clockworkmod )
i reboot the mobile from the recovery then it crash in the Sony logo it crashes in the sony logo which stays a long time i forced restart by pressing Power button+volume(+) ( tried one viration and three vibrations )
Then the sony logo appeared and won't go away.. I cant boot anything. doesnt respond to hard reset (3 vibrates)
PC wont recognize my phone.
then the same thing happened until nothing displays on the screen and the notification led litghs red lights red when I connect with pc or AC power
then the mobile doesn't turn on or start on recovery mode again and is not recognized by Windows on Flashtool or on the SEUS
i tried to remove/insert battery, waiting to battery drain, charging the mobile without results
what should I do?

When I hold vol(-), connect the phone to pc led become red most times and once in a way it become green for a short time then comeback to red not the time to do a full repair sony update Service or full flash with flashtool i did a successfull repair with the Sony update Service but stopped in the middle and then continued they said that's the phone is repaired successfully but i still have the problem ( won't turn on won't start recovery )

Can you try with another cable? Maybe the one you used is damaged. The phone normaly doesn't exit flashmode when recovery / repair is started.
If this doesn't help give it a try with newest flashtool, get a ftf file for stock fw .55 or any other version you want (would prefer any ICS version). Prepare everything in flashtool until you're told to connect the phone in flashmode than do so ( hold vol(-) ..., or do a soft reset and hold vol (-) with connected usb cable. If your phone enters flashmode (green led), flashtool should start flashing immediately.

EMERGENCY Brick!

hi,
any help is hugely appreciated.
I wiped my phone in recovery with the option to wipe for new custom rom, this worked fine. when i went to install custom rom it failed and then turned itself off. now the phone just gets stuck at the Sony logo. the only way i can turn it off is via the red button in the sim slot.
I am unable to connect to the computer at all, no fastboot. I'm also unable to boot into recovery to restore.
Please help. Hope i haven't ****ed it up beyond fixing
Thanks

Flash a stock ftf with flashtool (in flashmode). You should definitely get into flashmode and fastboot, otherwise there is a problem with your computer.

Funny, I didn't even know there was a red button Holding Volume Up + Power for a few seconds always worked for me, no matter in which state the phone was.

Hi all,
I've exactely the same problem !!!
My phone stuck to Sony logo, and not reconyze on my 3 PC.... before that, usb connexion work fine on all PC, but now.... nothing
I've just POWER + and VOL+ (its power off the phone), i've no led color light
I've try flashboot, but not detect my phone
i've try to install :
flashtool-0.9.16.1-windows (not detected)

I'm lost... I need your help XDA members ! just U can help me
PS : the red button is in the SIM slot, but i think is same POWER + (VOL+).... its power off the phone

Because you're doing it wrong. Vol+ enters fastboot mode, you have to press Vol- to enter flashmode. Then use Flashtool to restore the firmware.

Xperia M dual C2005 Failed flash (system.sin error)

I flashed my xperia m dual sim c2005 with firmware version 15.5.A.1.5, supposedly stock 4.3JB. Unfortunately the flashing process stopped during system.sin file processing and now the phone no longer boots or enters FlashMode. When I plug the USB cable, the green light appears below and remains even after I unplug the cable. For some reason when I hold Vol_UP and plug the USB cable FlashTool recognizes the phone in Fastboot mode; However, pressing Vol_DOWN to enter FlashMode doesn't appear to yield any outcome, not even a notification sound in windows.
I'm really looking forward to any suggested solutions.
Thank you...

try, press volume up longpress. for me it's working
