xEM RFID Tag [T5577 Emulator]
Installed two days ago. On the first day I used my white multi id reader/writer to copy a 125KHz access fob to my implant. I attempted to write a HID 125KHz Prox II code to the implant and it failed every time. I was able to make a copy with a blank card provided with the reader/writer and confirmed the write was successful.
When I try to copy the HID number to my implant it just tells me write failed. I have tried to position my hand in every possible way. The reader/writer has a strong antenna and writes to all other media very easily.
I attempted to write the 125KHz card info to the implant to see if the implant was bricked but it accepted to different card writes and worked flawlessly.
All I can infer is that my T5577 chipset is somehow locked from HID 125 KHz writes by the first write. Is this possible? How can I fix this? I don’t have a proxmark but I would be willing to meet someone if they did and this was of interest to the community.
