I always wipe my chip to a blank t55 when programming it. I got the info from this thread. Lots of good info in it. https://forum.dangerousthings.com/t/xem-cloning-emulation-modes-and-the-perils-of-chinese-cloners/1547
Command
lf t55 write b 0 d 00088040 t
b = block
d = data
BLANK t55 config 00088040
t = debug mode
After you run the command you wont find you chip with lf search as its not set to emulate a chip yet.
