this thread might seem strange to some people, but at the beginnig i thought "wow, rooting my device is going to be grat, im gonna do lots of stuff", but at the end all i do with my reader is, well, read.
So, in order to improve a little more the battery life and prevent any issues form happening, i want to remove the root from my device (or un root it).
Whats is the way to do it? I thought that doing a factory reset on the reader might do the trick, but it didnt, so, what is the safest way to do it? i dont care about loosing my book, i have everything backed up!
