It's very detail but some miss
If you put all 4 .zip files into ONE bootable CwMR uSD, step 9 you remove the uSD, insert the new one in, assuming it is blank then jump to step 14, you wont have the format file if you not re-insert the first usd back.
Also, flashing CwM into eMMC very convenience, yes, but it is a pain if you want to go back to stock ROM. I always preferred boot into CwM R via a bootable uSD card.
Your note in step 15, I personally do not believe it is 100% true. In my case, without an external uSD card plugged in, Aldiko Reader won't work. And yes, my system set up is like what you said.
