If the main page doesn`t say hack is always up to date, that means, i forgot to mention... 
Well, since we have similar nicknames I will try to answer you:nobodyXXL wrote:Hello,
unfortunately there is not much information available in this topic about how this "hack" was actually archieved. For me as a new user reading [1] it looks like all you are doing is install a widget (or extention or whatever Samsung calls it) using a developer mode of the TV (which Samsung apparently supports). Neither does any of the newer topics [2] and [3] provide any useful technical description of what is going on and what assumptions or vulnerabilities are used to archieve the goals set (I'm specifically interested in being able to mount samba or NFS shares). What is confusing me as well is that if all you are doing is indeed only installing a widget, how does (in the technical sense) a firmware upgrade prevent using those widgets? Also, if you are using a widget and then some exploit, I would also like to know what Samsung changed to make it impossible to use.
So I would be very thankful if you could shed some light into this. Feel free to split this post off into a new topic if you think it is inappropriate here.
Thanks
The sourcecode of samygo is available so, to understand how it works, download it and see for yourself.
About the exploit used it's a simple bug because samsung forgot to do some checks in the LUA scripts (the widget runs a small lua script that loads an unsigned/unchecked library which does everything else.
This has already been corrected by samsung in the latest firmwares and won't work on firmwares released in 2012.
