I am rooted, s-off, running Viper 1.6. I am on an the .25 firmware and trying to upgrade to .33 firmware. I do not have access to my computer, so I tried to rename the zip to run it in fastboot. I have done this before with other HTC devices (the M8), and it searched for the zips automagically, however my M9 does not. Any ideas as to why?
