Compile/Use Wupserver fw.img

# before beginning, don't forget to thank smea for much work on this
# and also the efforts of FIX94 for the automatic configuration

# install armips, python, and bash

# download iosuhax from here: https://github.com/FIX94/iosuhax
# or do:
git clone https://github.com/FIX94/iosuhax.git

# put your console's otp.bin at the same level as the iosuhax folder (not inside)
# you can get it with http://wiiubru.com/appstore/#/app/otp2sd

# go into the folder
cd iosuhax

# compile iosuhax
make

# you now should have a fw.img file, put it on root of sd card
# this fw.img is a custom firmware that only starts the wupserver

# to boot from this custom firmware, use the CFW Booter elf in HBL
# once booted, you can use another program to connect to and interact with it

# in the future, fw.img will contain rednand logic, and this is what you
# would replace on your sd card to boot a dump of your sysnand

# see http://pastebin.com/s7e1sceM if you have other issues compiling

# to start the wupclient GUI:
Download this:
http://wiiubru.com/appstore/wupclientgui.zip

python wupclientgui.py

# to start the wupclient command line (advanced users):
cd wupserver
# edit wupclient.py to use your Wii U's IP
python -i wupclient.py
