I am trying to install the new Marshmallow to my Nexus 6. I installed TWRP, the phone is rooted. When I wipe everything I forgot to do a backup and the ROM did not work. So now I don't have an OS on the phone. I was able to install some ROMs, but some of the are shown in my sdcard and the other ones are in the File Manager but the ones in the File Manager does not let me do anything with it. The ones that show in my are giving me the error Error executing updater binary zip. Right now I am just downloading all the android sdk to do some fastboot. Any ideas?
