Also you must use a usb 2.0 port directly from the computer not a hub. Factory data cable not a 3rd party cable can also make a difference. We know since it is a 912 that you are not unlocked. So you can only flash the same or newer version of what is on your phone when that time comes. Trying to flash anything as far as factory firmware goes from the sd card via stock recovery is a good way to perma brick your device. That is why I suggested making a list of the settings, about phone pages. It gives us the exact build of firmware you have on the phone, as well as baseband version etc.
thank you for the advice
i am using a branded motorola cable, and have been using a USB 2.0 port connected directly to my motherboard but i moved to a port on the back to eliminate one potential failure mode.
would screenshots of the settings info posted here help?
both phones have the same details
