Cannot unlock bootloader of Xperia S on Windows 8.1 64-bit and Windows 7 64-bits

[thsecmaniac]

Hi,

I would like to unlock bootloader of my Xperia S. So, I do as Unblock bootloader instruction

I hae different problem on Windows 8.1 64-bit (my home pc) and Windows 7 64-bit (my office pc)

For Windows 8.1 64-bit

I stuck at the 15th step. I don't get the response message. It shows only "waiting device" message even the LED light on my phone is blue (while I keep holding Fastboot button or release the Fastboot button after There is a blue LED Light ) which is only blue in 5 seconds  and the light turn into orange light

For Windows 7 64-bit

I stuck at the 13th step. The computer cannot find the driver of S1Boot Fastboot even I point to the usb_driver folder to let my pc find the driver file.  My pc said there is not a driver installer for the S1Boot Fastboot or I try to do as the second answer of this http://android.stackexchange.com/questions/61279/sony-xperia-zr-fastboot-driver

my office pc still don't recognize S1Boot Fastboot

Please help

Because you are running 64bit you will probably have to run the program in compatibility mode - If that still fails then you will have to use a 32bit based system
