No point covering that as EXACTLY what's used there is patched in "newer fw" :) Won't get you anywhere :)
All the same I'm interested in the technical aspects of it if you don't mind sharing?

+1 for a technical discussion. We love learning new things, even if outdated :)

sectroyer fears that disclosing technical details here we will help samsung technicians to find out what to do to stop us... So that such discussions are possible only privately or in hidden subforums. Big brother is watching us. Believe me. Time when we used to share all texhnical details is gone.

exploit webkit w/ jscript to execute shellcode binary which exploits kernel to gain root... since both bugs are fixed now you need to find/wait for new CVEs

We're talking in a private sub forum.....

And not sharing technical details of an already patched exploit is totally nonsensical. It's patched already, you think Samsung's coders don't know how it works? They patched it!

Edit:
And on second thoughts - wasn't the new firmware that patched the exploit released before this root was released? Suggesting they already knew about it without any public details.

well there are enough sites that explain how to exploit webkit and linux/android kernel. no need for that here.
its a different thing if you have a specific question about a technical aspect. for starters load the rooting binary blob ida and analyze it. if you have some technical question then im sure sectroyer will say a thing or two.
i dont even remeber what CVEs are used but that doesnt matter, as its always the same as i ve already stated above.

Yeah especially if find source code for many "parts" it's just a matter of using google ;) We have LOOOOOONG history (root, oscam, downgrade, etc.) of users asking to "share technical info" which lead to absolutely nothing :)

Of course I will :) I just see no point in writing "essays" about the sploit that somebody will simply comment "interesting" ;) Sorry I am not a writer, if I will be "in a mood" to write some tutorial/description I will definitely post about it here :) To be honest I recently spent 2 hours of my private time to explain somebody one of our rooting techniques :) You want info ask correct questions :ugeek:
