This thread lacks information. First of all you should give all the possible details of your console, like firmware version, region, old/new... And I don't understand the question, you could try using google translate...
If the question is if pasta will ever support emunand there's no answer, but you can use other things to get emunand, i'd recomend you Rxtools.
For the second part: If you're sysnand 9.2 or lower don't update. If you're on a version past 9.2 you can't get a "CFW", if this is the case the best thing you can do is update to 9.9 and download youtube as soon as possible.
Hope this helps...
