Simulating not working
tl;dr: reading a simulated dump with the keys from the original tag gives me a "no keys were valid" error. It also doesn't work on the original reader
I am trying to simulate a key on my PM3 easy (mcu transplated to 512 kb and reflashed with JTAG) but this reader is doing some check that blocks this.
I can copy the tag to a OTW keyfob or a direct write card but using a gen2a magic card gives no response from the reader.
When I try to simulate my dump I get no reaction from the reader (no green or red light) and the same goes when I try to simulated the dump with my chameleon revE rebooted.
The steps I followed are as follows:
Discover all the keys (used hard nested because the Prng was hard)

Re: Simulating not working
I'm having the same problem, but I don´t have the necessary amount of knowledge to fix it. I'll continue my search and if find something I'll post it here.
