It doesn't sound like my issue was quite the same as yours, but I had difficulty upgrading an older version of dd-wrt, and ended up going back to stock DLink firmware. At that point, I was unable to install dd-wrt with the factory-to-ddwrt.bin file, and I tried several.
Turns out that one of the replies I got to my post suggested that certain versions were better suited for the DIR-890L than others (https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=315606).
One of the versions he suggested in that post (r35531) finally worked. I'm now having reduced bandwidth issues, however.
