yes they very much can, although very unlikely it is still totally possible to brick a gen1 with bad writes
my advice? leave it be. for like a week. then when you’re prepared to do your cloning do hf 14a reader -@ and use the pm3’s hf antenna (use the underside of the device) against the implant until you get consistent ID output, then when you know where the coupling is good, do the write command then.
don’t worry if it fails halfway through, coupling needs to be tight
edit to add: @Aoxhwjfoavdlhsvfpzha describes it best but yeah while you’re healing all that blood and tissue fixing going on inside your hand is gonna make it harder to read/write so writing to it will be harder ergo it may not even work on your desired reader until that healing period is over & you’re able to get the most of your implant
