I think I have a bad download of the .5 file from xda. I cannot open it with windows explorer (and not really sure if I'm supposed to be able to) and don't want to flash a bad file. How can I check it to make sure its not corrupt? Is there another location to download it other than the link on xda? I've tried it 4 different times and keep getting same results as far as windows explorer not opening it. The file size is 440.4 mb that I have downloaded so that seems right at least.
