I’m a proud new owner of a NExT, and I’ve had a lot of fun with the HF side of things so far. I am hoping to enroll myself in the access control system at work (and have the security dept’s full blessing), but I find myself needing to change the mode of the LF side of my implant from the factory EM41xx mode to HID Prox mode. Having a specific ID is not as important since I have the opportunity to enroll a fresh tag — no cloning necessary (though I do have an existing badge, so cloning is an option).
I’ve read through threads praising and later advising against the “blue cloner” (and I see that the “trusted” model is no longer available on the DT store). I have also read thru instructions for the Proxmark, but I see that the “easy” model available from DT is not compatible with the ProxLF antenna and have read that positioning is tricky without it. And the RDV4 is… Expensive.
So, my question: What is the community’s current preferred or “best practices” way to write to an X-series LF tag? I’d like to minimize the risk of page tearing as much as is sensible… I would hate to brick the LF side of the tag, since that was most of my motivation to get the tag. Or, am I bring too paranoid, and will I be able to take care of this with the Proxmark 3 if I’m careful and have a steady hand?
