Preloader handshake fail

[Sym8]

device nokia 5.1 plus (mtk6771) Android 10 Windows 10 Preloader mode doesnt work and i get this error

Preloader Preloader - [LIB]: ←[31mStatus: Handshake failed, retrying...←[0m brom mode wroks but im unable to dump boot and vbmeta images.

I have looked and tried things mentioned in other threads like deleting mtk 5.1824 file bypass tools etc and nothing has worked.

I can unlock and relock the bootloader but im not sure if it works since it says i should use it in preloader mode?
