Need help with transfer.

So my tablet chose the perfect time to crap out on me, it's been charging while off for a good 17 hours or so and has gone from 21% to 5%. I found a tablet somebody's going to sell me cheap, but I need to create a transfer code. Once I start up my tablet I'll probably have 3-4 minutes at best to get all this done before it probably quits for good.

Anyways, if possible I need the exact run-down of what to do to create the code. Also, I've never transferred before but I have a few stones saved up and I am literally in the middle of a tourney run so I'm not sure what to expect. This account's 695(?) days in and I would hate to lose it.
