I am using Sony Xperia Tipo from past 1 year. I rooted my phone recently and I am trying to unlock the bootloader:
I am trying to unlock the bootloader with this procedure Instructions | Sony Xperia
Everything went fine till 11th step.
Acoording to the 12th step when i tried to connect the device in Fastboot mode my PC showed "Device Not Recognised"(it had shown like this when I tried before also). ok I just ignored it.
In the 13th step it says "On your computer, you will be asked for drivers" but I wasn't asked for any drivers. I mean any sort of Window popup asking for drivers(I don't know what should have happened at this step). But I proceeded to the next step.
According to the 14th step I opened the command window and went into the tools folder within the Android SDK folder.
According to 15th step i entered fastboot.exe -i 0x0fce getvar version but it shows "WAITING FOR DEVICE" in the Command Window. I got stuck here.
As Google has disabled driver singnature enforcement in Windows 8. I even checked whether ADB drivers were installed, it was installed, no problem with that.
So what might be the problem??Please someone reply ASAP
