Cannot link the image directly for download as they have an anti-leech installed but here is the directory link where you can then download the image from...
Big bonus, it has a working mgcamd, probably the only DM900 image out there with working mgcamd too. Cccam2.3.2 also working. Oscam and some others also there but not tested them personally.
