So I’m traveling to get my FlexUG4 implanted and decided to do some field learning on cloning hotel key cards. I followed this forum post after running into static nonce errors. I was able to find the last two keys in the default keys and finally able to Gload the bin to a Magic gen 4 card. Testing the clone failed but the reader did respond as if presenting the wrong door card. After doing an “hf mf info” I found the ATQA didnt change, and using “hf mf csetuid” to try and change it didnt work.
Loading and simulating the dump file with “hf mf eload -f” and “hf mf Sim” then holding it up to the reader did unlock the door as if it was the original card. So i know the file and keys are good, it just seems to be something wrong with writing it over to the Magic Gen 4
Is there a way to change the atqa by itself or is there possibly something else Im doing wrong?
This the “hf mf info” of the Hotel card then the cloned card
That worked perfectly for charging the atqa, unfortunately the card still doesn’t work. Second unfortunately, is I have to travel back home, but this was great learning! Thank you for your help and sorry for the late reply
