x10 Vibrates but never turns on

[#1]

After a failed flash upgrade, I cannot turn my phone on... It just vibrates and then always on blank/black screen...

Hoping for your help

Backup everything as it will erase all data on phone (sms, contacts,apps)

Update/Repair your phone via PCC OR SUS

PCC (PC COMPANION) – Repair your software with this .First do the setup without connecting your mobile to pc.(only connect when you are asked to).

Do it as follow >> PCC > SUPPORT ZONE> SOFTWARE UPDATE> REPAIR SOFTWARE (written with blue)  

PC Companion http://www.sonymobile.com/global-en/tools/pc-companion/

SUS ( Sony Update Service)  ... download and install it on pc and follow the on-screen instructions http://www-support-downloads.sonymobile.com/Software%20Downloads/Update_Service_Setup-2.11.12.5.exe

                  or

Already installed but the PC Companion/SUS shows that my firmware was the latest..I want to still "install anyway but there are no other buttons but the "exit" one.
