MSI H61M-P21 (B3) bootlooping

Hello everyone, and thanks for this forum,

I tried to update BIOS on my H61-M B3 mobo and something went wrong. After updating I had no video signal. I tried reseting CMOS through JBAT01 and removing baterry with no result. It is only bootlooping. When I connect USB drive it is trying to read from it and the pc stays on. 

Thanks for any help
