Clicking that link renders the "invalid forum specified" error.I truly hope this mahmoud007 fellow's theory proves valid and his method works. I just scolded him for cross-posting a hypothetical solution for the S4 i9505 because the reason he cited for not wanting to test his own creation was that he was still under his Manufacturer's Warranty. After I clarified that the KNOX Warranty bit was unrelated to Samsung's service warranty, and asked why he felt it appropriate to request others risk permanently altering their own devices using a method he created and wasn't confident enough to test out on his own, each and every copy of the cross-post vanished within minutes. With luck, some admin wiped them out so his work couldn't be plagiarized before the applicable bounty could be announced.
Good luck, mahmoud. Here's to hoping XDA's senior developers are working with you at this very moment and that you've made history by cracking KNOX.
