You also need to give this parameter to UBI: 
vid_hdr_offs=2048

I.e., modprobe ubi mtd=1 vid_hdr_offs=2048

Or if UBI is compiled-in, boot with the following kernel argument:

ubi.vid_hdr_offs=2048

With this option UBI will not use sub-pages at all. I think it makes
sense for  you to try how it works this way.
