That Kindle has two different builds of u-boot.
Have you tried them both?
(The more complete build is named: BIST on the first level u-boot's menu.)

On earlier Kindles, installing u-boot was done with the erase-all command.
You will have to read the sources that Amazon has released to see if that is still true.
Ah, what your looking for in the sources:
The erase-all command (after forgetting to save the device and personal info sections) did just that, erased all of the mmc and then unlocked the u-boot storage area and copied the then executing u-boot into mmc followed by re-locking that area.

BIG NOTE:
The Paperwhite gen 2 is not the ideal device to be used for a first-time explorer.
(Since you had to ask, you must just be starting out. Starting out on this device is a really big "bad idea".)
