1) Not possible because my original H2O is now open (Bye waterproof!
) and by the moment my second hand H2O has only KSM09up2, KOreader, Vlasofsoft Launcher and Plato. No patches and no mods.
2) Coolreader and his launcher (last version on his web, I don't know if there's a new one driver shared) run smoothly but I will try and edit this message later.
Edit: All go well now with the h2o driver.
Edit 2: You are right. Only work correctly with (2,90). With the other three combinations with correct orientation the select don't work well. The screen respond but not the correct character
