I implanted my xM1+ on Dec 5th and not long after formatted it as NDEF because I didn’t have another use-case yet. I have now experienced that my implant won’t read anymore, not even with the Proxmark. My last write with my phone was successful and I could both read it with my OnePlus 3T and my iPhone XS Max. I was trying to read it one day, but couldn’t. I thought it might be alignment with the antennas in my phones, but also other readers that reads the implant easy wouldn’t read it longer. I later received my Proxmark3 Easy and soon began to do some research on reading the chip and try to get some response there. I have tried the 14a, mf and general hf search. But no response at all. I have tried to send raw commands, aka. the remagic.lua within the scripts-folder, without success and no response to the commands. My Proxmark reads my dads xM1+, and I have checked the alignment against mine on the antenna to make sure to have good couplings.
Is there any other tips and tricks to try out? I am starting to think that it is completely dead
Thanks in advance!
