when the HEN exploit was published I had problems with my internet provider so I installed it offline using the experience I got with HAN exploit using it as a bridge to install HEN, you can try install HAN to get install pkg function in xmb menu , then enter the mini web and use han_flash_mount_rewrite.htlm then install the HEN pkg and that would be it, use the easy network configuration in the console for some reason the manual configuration does not let me view the miniweb server. I will leave utility files,
EDIT BY MOD:
Get files from official site. they are there, i just checked.
