Nexus 5 update to Marshmallow using ADB/Fastboot

I tried to update my Nexus 5 to Marshmallow using ADB/Fastboot and Googles images. I have followed a number of different (yet the same) approaches to flash the unit and NOTHING works. I tried to go back to 5.1.1 and can not restore the unit. It has not bricked (yet) and not sure what to try next. I have read options that call for reformatting parts of the operating systems but fearful this will brick the unit. I have flashed the bootloader, phone, recovery, userdata, sys, etc., and nothing works. I know others have had trouble with Nexus 5 based on what I have read however to date not be able to restore the device. Has anyone found a solution?

Re: Nexus 5 update to Marshmallow using ADB/Fastboot

1. Get the Wugnet Nexus Root Toolkit at WugFresh
2. Select "Soft-Bricked/Bootloop" and then Flash Stock + Unroot
3. Start your Marshmallow update over again using the Wugnet Nexus Root Toolkit this time
