Can I downgrade Pioneer BDR-XD08UMB-S firmware?

[kimbap]

I recently bought Pioneer BDR-XD08UMB-S.
I realized that it needs old version of firmware in Pioneer product to use LibreDrive after I ordered.
I'm delivered my drive today and I checked the version of firmware. it's 1.02

Is there any way to downgrade it's firmware?
Is the only way to use libredrive making a refund and buy another one?

No, the firmware can't be downgraded.

Return it. No point buying another one as they all will come with the incompatible firmware.
