Here is the AOSP Marshmallow ROM for A7000. It is ported from the 6753-zopo speed7.
It needs to be extracted to your TWRP folder and you can restore it. Remember to rename the last entry to your current twrp backup folder.
TWRP>BACKUPS>WCNZTWD6OFCMLFMR>2016-04-26–11-37-22_ZP951_20160330-120131
or what shows up in your backup folder.
TWRP>BACKUPS>AIO-ROW>2016-04-26–11-37-22_ZP951_20160330-120131
The google CR'APPS' have been removed.
