Adding My Motorola Milestone 2 Android Phone
===

I have searched your database of questions and find questions related to my problem but not an exact answer so I hope someone can help me. I am very new to all this so appologies if I don't use the right terminology. I am simply looking to root my device, though I hope answers to my question will help other people too. 

Following instructions I researched, I installed the android SDK on my Windows 7 64 Bit machine. I then replaced the USB driver in the extras\google folder with a modified cyanogen driver, which, I was told, would facilitate communication with more devices. In control pannel/system/advanced system settings/environmental varyables/system varyables/path I added the adresses of the platform tools and tools folders within the sdk directory, seperated by semi-colons as instructed. I then enabled debugging in the application settings menue. My computer showed that it was attempting to install drivers. However, when I opened a command prompt and typed add device I was told that Windows didn't recognise this command. This was anticipated in the instructions I read so I restarted my computer first, which didn't work and then tried to make sure the driver was installed through device manager. I browsed for the .inf file and clicked on it. Device manager returned the error that there wasn't an appropriate file in the directory and that I should make sure the driver was compatible with a 64 bit system. 

The upshot of all this is that, as far as I can tell, my device is not added and therefore I can't proceed. I would very much appreciate any help that you could provide, 

Thanks, 

Justin
