But then I wrote a io prox card to the exact one I was trying and it worked perfectly, I have tried lf t5 detect and wiping it multiple times, any suggestions?
Can you screenshot the startup of the PM3 client to show the client and firmware versions match?
At this point beyond testing a different T5577 just to make sure it isn’t a weird issue with the target card, I’d suggest just retrying the clone several times to see if you can get it to stick, sometimes they’re picky
I’d definitely recommend trying different positions of the tag on/under/around the PM3 too, it can make a big difference
Thanks for the tip on trying around the card, I have tried cloning it multiple times as I know it sometimes takes a few tries, but hopefully I can figure something out.
