if you do a

lf search;
lf t55 detect;
lf t55 info;
lf t55 dump

And share that dump file / textout from the lf search with me.

Can you help me? Thanks

No, the dump should just read out the source T5577 tag’s memory to a file… which it looks like you’ve already done. Now you would just restore that file to a target T5577.

Pretty sure it’s lf t5 restore but check the client… it’s easy to poke around the commands.
