honestly i would return your proxmark at this point mate, the keys I’ve sent you should do the trick and make it so you can dump them but your proxmark is not playing nice, aliexpress proxmark quality is incredibly shoddy and the recent influx of even lower quality proxmarks makes finding a good one a real challenge.
DT sell one “pm3” hyperlink should take you to the product page, they’re a bit more expensive but they’re order-fabbed by DT for assured quality & flashed with the iceman bootloader for easy updating.
for the love of god do not get a chameleon ultra the chameleon ultra is still in its very very beginning dev stages and is essentially useless at the moment, development for the firmware has basically been abandoned, its fully open source so someone someday might pick it up and decide to make it worthwhile but as it currently stands, buying one would be a waste of money.
the proxmark is what you need, you just need a reliable one.
