DROID 4 ADB Driver for Linux

I'm trying to unlock my phone using this tutorial. It stated that: Prerequisites - A computer with DROID 4 adb drivers installed . alternate link - Enable USB Debugging on your device by going to Developers options. - Download RAZR BLADE exploit by djrbliss from here. But there are no Linux driver, or is it not needed for Linux? Why I need this? because I need to remove /system/app/VZWPhoneService.apk and /system/app/VZWPhoneService.odex. then reboot. , because the other way already expired . So I could use this phone using another carrier. The alternate method also requires Windows OS.
