Why are you using hen 1.6? I don't use rest mode, because I always unplug devices I'm not using... but common sense dictates that if you want stability, you should always use the latest version of whatever you are using.
In the case of Hen, you should be using HEN 2.1.3. And if you want to use the current and latest alternative to Hen, you can try GoldHEN 1.1 as well.
I switched from cached exploit to al-azif who has basically nothing available for 5.05 anymore. Can't even FTP. And the 2.0 and 2.1 HEN exploits don't work, only the 1.8 one does. I'll go ahead and try loading exploits locally instead of loading them through the website.
