Xperia S not able to boot

[santerrific]

Recently Unlocked bootloader officially from sony mobile website

later on rooted it from xda

installed custom recovery mode through FASTBOOT MODE

after installing it led me to recovery mode

i backed up my data

then i selected REBOOT SYSTEM NOW

but its again rebooting to recovery mode

not going beyond that !

how do i get over it ?

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.

device is stuck on recovery mode ! not able to turn it off !

powering off is again rebooting to recovery

[Sam]

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
