Yes exactly, I have the same laptop and the same issue. If you find any solution, be sure to let me know, and so will I! :D
I think I might be able to clear up some confusion around a patch existing or not. Cameron Berkenpas did try to add support for the Slim 7i using some logs I provided, but that didn't turn out fixing the csc3551 error. So thats why, I think, in his patch, the Slim 7i model (16IAH7) is listed, but it's not working, at least I am unaware of any success anybody had with it.

I have more or less given up on this for now, because at least with my (nonexistent) knowledge of this stuff, I don't see anything in my power I can do. But if anybody has ideas what to try or where to look, I'll happily try it out.
