I’ve had my xEM implanted professionally.
I have one of those Chinese blue HID/EM cloners (insert eyeroll, you know where this is going) which I’ve used to try and clone an existing HID Prox card. The read of my xEM to the handheld cloner went well, so I did a read on my HID card (which also went well), and then a write to my xEM. This didn’t show a “pass” light on the cloner. Which means it didn’t go well. Subsequent reads of the xEM also failed.
So it seems my xEM is bricked from the first try. My skin hasn’t even healed yet and it seems like the xEM might already be less useful.
I ordered a proxmark 3 which is on its way (about 3 weeks away I expect), I had this ordered before I received my xEM, but the temptation of having a cloner close by hasn’t helped.
I can’t seem to find any information here on recovering from a bricked xEM; although it seems to be very a common occurrence on this board.
