To start, I am not new to android or ADB, only HTC. I have been messing with Motorola android devices for years. I have downloaded the required RUU downgrade from the XDA thread at least 15x and every time I get finished and attempt to open it to move the files I get an error that says the .zip is invalid so I cannot move forward. Anyone else having this issue? I have downloaded the custom update and moved all files to platform-tools no problem, but it seems no matter what I do I cannot get this dang downgrade right. Thanks!
