So basically the gen1a backdoor version of the magic mifare means you can mess things up and basically always be able to get in via the backdoor and rewrite things… the gen2 has no back door so if you accidentally lock a sector there appears to be no recovery for that (just like a real mifare).
You’ll also need to use the proxmark3 to crack any keys on your source tag, if there are any used… you could post a TagInfo full scan to see if there are any sectors being used for anything specific… otherwise just the ID needs to be cloned.
