Got my Solo, GoPro 3+ And iPad Mini 2 last Saturday. All firmware was updated and devices all charged and Solo calibrated. I am a total novice at this and did not know there was a preferred start-up sequence. I have just been making sure all the preflight things were done, but in no particular order, except that I turn on GoPro and set it to record last. Solo flys perfectly and I get streaming live video to the iPad Mini evey time. Should I be following one of the recommended sequences. I have learned a lot from this forum.
I personally have tried multiple sequences and all have worked. If you have a sequence that works for you, then use it. I don't think it's understood why one sequence works for some and not others.
Just take it slow while you're learning.
