Did you mount vendor before flash dfe? Do use DFE 13 or the old DFE? Try with both.
I used adb pull to copy a text file while its on the TWRP logo and it worked. It just isn't booting to TWRP for some reasonThe easiest way is to backup your data to PC and do clean install + format data. Now it's a bit mess I guess you mixed things up.
