[blacksb5]

Hello,

I've recently updated my Xperia S to ICS and it worked fine for sometime; and now i've faced a terrible problem.

once, it crashed and i tried restarting it, after restart, Sony logo appeares and phone restarts again and again, till it's out of charge.

any Ideas or clues?
thanks.

You can update using PC companion or Sony Update Service if you have locked bootloader. If you have unlocked your bootloader you can flash the firmware via flashtool and look for 6.1.A.2.45 firmware at http://forum.xda-developers.com/showthread.php?t=1857924.

the terrible news is when  i want to repair my phone, i choose my phone and then it says i have to plug it out and seef if it's charged 50% ( i charged it fully) and then it says plug in the phone again and press down the volume key and when i do, nothing happens!!!

any ideas?

You need to hold the volume down button and keeping it held in connect the usb cable - Nothing on your phone screen will happen as it's booted into Flash mode

@blacksb5

you can use PCC to upgrade your firmware.  just be sure to remove your SIM card when doing the update so it wont restart.  I just upgraded mine yesterday, and it seems that the reboot issue is not happening YET (I will hold judgement after a week of using the phone. The lastest version build should be 6.1.A.2.45  anything lower than that, will have the same issue..  I actually think the GB version was more stable than the first few upgrades they have released in ICS... but with this latest patches on build 6.1.A.2.45, I assume they have had a lot, tons, millions of fixes made lol

You have PCC.For the update,you will get a notification in the left corner of the app.For your firmware,go to settings-about phone and there you have it.
