Hi, I updated the instructions on the wiki to update the commit tag. You shouldn't need to switch branches if the commit tag is correct. It looks like the old commit tag disappeared. I tested with the new commit tag on sina-a33 and it appears to work. (make sure to use correct u-boot config and dtb) If this commit tag disappears, the patch should apply to anything close to 4.12-rc1 in the sunxi-next branch.
Hope that helps.
