I unlocked earlier some bin2 without any problem maybe the compilation? So what i can do in this case? what it means "downgrade" as i know is not possible to flash firmware bin1 to bin2.

Hello
GCPro support STL550TL U1 direct unlock only.
Any other need root and adb unlock.
Diag Exynos unlock for such phone only read cert TFN do not unlock over codes so it will not read codes.
