RUU not working error 171 help Windows 7

Okay so I tried to update my HTC Desire 626s (tmobile) to android 6.0.1 marshmallow but when I went to update using my phone it said that it was meant for a32eul which my device is so I tried to update it using RUU and after I tried that I think I bricked my phone the RUU failed and I can only access boot loader download mode and stock recovery in stock recovery I am able to adb sideload but other than that my phone is not detected by adb on my computer when I do use sideload to try and sideload a zip or new recovery I get E: footer is wrong E: installation error installation aborted in download mode here are the specs
