Please ensure you are not holding down the volume button whilst it is turning on and if you have a case attached that could be interfering with this button please remove it.

When you say you can’t power it off, have you tried holding the volume and power button to force a reboot?

You need to flash a kernal.sin via Fastboot - If you have an FTF file change the name or file extension to .rar then open it up - Find the kernal.sin and extract that file only and copy it to your Fastboot folder on your C: drive then open a command prompt and type fastboot flash boot kernel.sin then hit enter and connect your phone in fastboot mode - So hold power and volume up untill you feel 3 vibrations 1 after the other not one on it's own 3 will come soon after then holding volume up connect your usb cable it should then sart the flashing and fix your phone

If you don't have an FTF file then post back with what version you are running ie@ GB ICS but which variation .452 .453 2.45 2.50 or 2.55 I will then be able to post a link for you to download the kernal.sin

If you've used Flashtool not Fastboot then for Flashtool you need a .FTF file which is the firmware some of use to manually flash our phones the kernal is what boots up our phones - If you need a kernal then post back as above which version of software you have

Takes seconds to complete - Once done your phone should reboot if not then you may have to use Flashtools or the new Sony repair program

the phone is still rooted

How do i enter into recovery mode without being stuck agin and install custom roms ?

Re: Xperia S not able to boot

Recovery mode is a separate file which you need to flash using fastboot the proper file to use is the nozomi file found on my drive here https://docs.google.com/open?id=0B-yM_qnM8ZPRU2VWazlla19tWE0

To use as you just did with the kernal.sin you need to copy it to your fastboot folder and type in

fastboot flash boot recovery-nozomi.img then your phone will boot into recovery then to fix that re-flash the kernal.sin
