Hello,
I've just swapped the SD image of my Kobo Glo, using another one coming from another Kobo Glo.
Now I'm facing a problem: the device works but the text color is not uniform, some kind of gray instead of solid black. After some digging, I've discovered that each screen is calibrated (waveform) and tuned by the factory.
Now, I wonder where are the calibration datas stored and if I'll be able to fix my display problem. In other words, is it possible to update eink waveform and if so, how?
BTW: I read about a lot of people asking for the SD image. It's only me with this problem?
