MCU update bricked my device?

[Billkaza]

Today morning i tried to update MCU with kld5 v2.97. Previously i had kld6 v2.91.
Afte that unit never booted again. All i get is a quick flash of malaysk boot logo for one second and then black screen with devices button lighting from blue to pink all the time.
I tried to flash firmware again with rkbatch tool and after finishing with success the same problem again.
Is there any way to flash old MCU again? Is there any tool to flash MCU from pc?
