The reason it is part of the conversation is that it goes to show bad faith on the part of TX. They made a claim that they had cracked the uncrackable and posted a video to prove it, shortly after GBAtemp users pointed out that this was in fact not true and they then removed the video. Going to show that either they aren't sophisticated enough to even know the difference between a patched or unpatched unit, or that they are blatant liars.

I can see you have only been here since october, but if you had been just a few months earlier you would have been around for the post where they claimed to have already cracked patched units and showed a video to prove it works, which was subsequently found to be untrue.
Sorry, I meant to remove this quote as several others had given information on how to easily update without any permanent effect.
Please just stop, I am embarrassed for you.
