You have to edit makefile, you will see python2 twice replace they to pythonC:\Users\aaaaa\Downloads\iosuhax-master\iosuhax-master>make
make: python2: Command not found
make: *** [sections/0x5000000.bin] Error 127
I havd an error,but I could make Wupserver.bin and Wupserver.elf.
However, I couldn't run it.
And for the sections error go to punderino's pastebin and there's a link to a file with some sections, try to put 0x5000000 in iosuhax/sections folder
Other option is be sure you have the correct version of Armips (I have x86 windows with 32 bits of Armips)
The last option its try to compile modified @FIX94 IOSUhax if its for get a CFW (thread its in homebrew section)
Bye!
