So then we have to find out whats the difference between our installations. I installed the image like instructed here: https://wiki.merproject.org/wiki/Ada...eps_to_install Installed via CWM Recovery. Then upgraded like instruced in the same wiki to the latest version. Did you install via another method ? Maybe used another cm base ? If not. Then we need to find out if there is different hardware involved. But I hope it is only a software issue and not hardware related because that would mean we need different drivers for different models which makes everything a lot more complicated.
