so I have been using SKY3DS+ and was planning to use it as long as I could to avoid going through the trouble of CFW but also liked that I had the option to put cubic ninja on it and install A9LH when ever I wanted to. with the new firmware though it seems like its time to install CFW. the main thing that has kept me from doing it is not the difficulty but the fact that you have to keep your device out of commission for many hours. I've heard between 4-8 hours which to me is an insane amount of time to be worried about it bricking. I am currently on a New 3DS with firmware 10.7 so can you guys give me ideas of how long I should expect it to take
