No, the device doesn't have to be rooted to unlock the bootloader. Just get your password from Sony site, and enter fastboot, just like the first time you did it. Remember, you will lose all your data.

Otherwise, as pvy said, flash stock kernel with FlashTool (tick all the boxes apart from "Exclude Kernel" and "Wipe Data"). That way your data will be intact.

but the phone doesn't turn on,, so i can't get the IMEI from my phone to unlock the bootloader!
isn't there any way to get that number?

You can get your IMEI number from the box your arc S came in or just look under that battery. It's a 15 digit number. When you enter it on the Sony unlocking site, just exclude the last digit.

Cheers!

just try what pvy said,.

first you flash the kernel Only.,
then try to un-lock it Or install a full stock firmware.,

Do note that you WILL lose all your data (whatever is on your SD card is safe) but your phone should work again and with the stock ICS. You can then proceed with unlocking your bootloader and rooting it.

at the first time it didn't work
but now it works ))
