I did everything you said and the video explains very clearly how to do it, I even tried to put the info in a SD card and as the error continued I tried to put it in an USB and did not work either, so yesterday, I took the risk and upgraded it to 4.2.2 version, I lost everything but I just installed the kodi repository add on by following another tutorial on how to do it, and I am just recovering and installing everything I need from there, I also installed others repositories in order to make sure I have all add ons I had before, the most important thing is that the video resolution was fixed.
but now, for some reason, my remote control is not working, I am using my mouse, but I would like the remote control works as it is suposed to.
