It is specifically package for people who can't stay away from the 'Reset' button.
Installing it, try, in order:
MrPI (put in /mrpackages)
UYK (put in / visible USB root, then "Update Your Kindle")
Reboot into it (put in / visible USB root, then reboot using a press and hold of the power button)
At least one of the above three ways to get the package to install should work.
report back on what you try and what the result is
