I have had my NExT a little under a month and was going good, played around mostly with the xNT side because I could just use my phone. I did add the xEM to my front door so I know it was working but about a week ago It stopped responding. I bought a proxmark3 easy to diagnose and build a pretty good antenna but I am not getting anything.
I have tried the following-
lf t55xx detect
lf t55xx p1detect
lf t55xx wipe
lf t55xx write b 0 d 00088040
lf t55xx write b 1 d E0150A48 1
lf t55xx write b 2 d 2D782308 1
still no detect
I have confirmed I have no issues with a another t55 card
lf t55xx trace looks the same as if I have nothing on the antenna
hw tune gives
LF antenna: 28.60 V @ 125.00 kHz
LF antenna: 21.59 V @ 134.00 kHz
LF optimal: 28.19 V @ 123.71 kHz
HF antenna: 25.35 V @ 13.56 MHz
and screen cap of lf t55xx trace with my NExT
any suggestions on what else I can try
Thanks
