I think this is great idea. I was thinking; "If you can see the mods that said tool is making, and use your toolset/skillset to do the same thing to a stock efi dump, no need to reverse engineer anything." And then I read your idea and HAD to reply .. I love how your mind works.
How do you think KadenTech is being able to turn off and on the use of his device. Such as when you use it must purchase licenses before hand how does he control that? I would think it could be reversed engineered and do you believe he is a engineer. It seems he must know something that no one else is finding because his device is able to almost instantly delete the efi pw. I think it somehow locates the location of where the pw lives and deletes just that section.

what his tool does and what the efidL does is very similar.
the efidL could be faster, but a slower speed is safer. with raspberry pi and spispeed=8000, i can dump/write whole efi in 15 seconds
i used to install clear paint protection film on automobiles with the invisiblepatters setup. you would buy a roll of film, and it was accompanied by a "cut code" which you would enter into the software, and it would allow the software to cut the amount of film you purchased.
it could certainly be reverse engineered, like a key gen for shareware, but KT would still be selling equipment and just not unlock codes.
that whole pay-to-play mentality is certainly entrepreneurial, and while that's not a bad thing... that's not our thing. ROI is all we need.
I just haven't seen anything like what he has and I am curious again how he can make it where it cant be used like he makes you buy licenses I am curious how the tool doesn't work if you don't purchase them. There has to be a way of reverse engineering that and then his tool would work instantly everytime in 10 secs
i'm not sure what the license delivery method is, as i've never used a kadentech unlock tool... but like i said, it's a simple shareware principle:
the tool will operate when it's instructed to do so, and it's only instructed to do so when licenses are present.
it could be reverse engineered, but rather than hack his tool...
Oh I see now they have a EFIDL Tool on here that will remove exact location of pw without reading efi and putting it in clean dump etc.. ??? I didn't see that before I already spent $160 on tools used to read efi for all mac's like air and pro and some other tools came with it but I guess ill buy the EFIDL so that ill be able to do it the easier way if possible and use my other tools on other eeproms
Thanks I have never done this before reading the efi on apple stuff but I did successfully erase eeprom passwords on ibms but the tool just attaches to the chip and then erases it or shows the pw etc. I want to buy this tool if it will auto unlock the macs for me I bought several MBA & MBP and can get good deals on them . Where can I buy this tool
