[coolrevi]

hey. i am a xperia pro user.. i tried to unlock the bootloader.. i installed latest SDK and USB driver package. i copied the given file in required place.. but when i try to update driver it does not get installed.

are you aware that you will void your warranty and even if you relock the bootloader the DRM files will be forever gone?

Open the Dialer and press this

*#*#7378423#*#*

check if you are allowed to unlock the bootloader

[coolrevi]

yes. i've checked it.. it is allowed

[Uliwooly]

this might be a dumb question but did you unzipped the files?
