I have tried to change the value, but it still does not allow me to see it,
this is the value that changes

As I already said, I know the keys and can write block 3, but I can't write block 1 and 2
and i can't see the whole block 0
sorry, it was an error of appreciation.
the line of code says it was written ...

--data: FF FF FF FF FF FF 78 77 88 CB A0 A1 A2 A3 A4 A5

but when reading block (3) again, it appears that nothing has been written, it is the same as before.
the line of code was not written, but it says (-> isOk: 01 <-)

I use proxmark easy ..
maybe another hardware?
maybe another way?
