Hello
Does unlocking with octopus have signal problems after reading codes via server?

SM-G930P 8.0 Unlock problem

Hello to everyone. I've phone with Oreo G930PVPU7CRG3 firmware.

I can't root my G930P, can't downgrade to COMBINATION_FA60_G930PVPU5AQI1_CL7396706_QB15051611_REV02_user_mid_noship_MU LTI_CERT
I've tried EngBoot for Oreo and Nougat from here:
