One guy sold me vcc with 5313211381501836
and I bought other 4 vcc with him same BIN
but all vcc has different year and different months, like one is 2020 and another is 2019 and months are also different for all 4 VCC.

I think he is generating it some way..

Can anybody tell me how he is making all these working VCC?

I will pay you if you teach me..

Thanks!
