It looks like your card is in gen1a magic mode, so I’d try the C chinese commands for gen1a, particularly to make sure your key blocks are set to the correct defaults.
Perhaps hf mf cwipe, will do all that, but your UID will get set as well.
I think so, all the c commands like cwipe for gen1a magic tags should completely ignore passwords and access settings.
do hf mf -h for a list of all of them.
as far as I know there is pretty much no way to brick a gen1a card.
the down side is many systems look for them, so it the perfect copy doesn’t worrk, and is then corrupted after you tried, your system probably killed it!
I’m not quite so sure about the gen4. I know you can have gen1a, gen2, direct write, and the alt gen1a which is the 20 23 wakeup, so I’d probably load up the card and then switch it to alt-gen1a right at the end.
I would be very careful turning of the magic options, as you might completely lock yourself out of the tag if you do.
I just don’t recall offhand if the gdmcfg can be locked, Probably there is a way, but I’ve never been game to test that!
As long as you can get to gdmcfg, you can set a gen4 card to gen1a and save it.
Every magic card comes from China and they don’t know what they’re dealing with. I buy chips and I get a mix almost every time. There’s no model numbers or SKU or any kind of code that would tell anyone in China what exactly these products are so they just go by nomenclature and tribal knowledge. Almost every time you’re going to get some mixed bag of magic capable chips. There’s no way around it when the market producing these legally suspect products is so chaotic.
