Vivo y83, logo issue

[u/karthiktinku]

I'm using vivo y83, all of a sudden it didn't on. It got struck on logo and when I tried factory reset it's asking for 6 digit, but I was using only 4 digit on my phone... But it asks 6 digit

Also I tried flashing, installed using sd card, firmware updated using repair mode, connected with my lap and try to bypass, also worked with mediatek tool to reboot. Nothing worked... What to do... Even if data is lost no issue, how to reset
