My notebook keeps recovering BIOS after BIOS update

[Andre1233]

Hello! You are my only hope.

My notebook keeps restarting after BIOS update, and tries to recover BIOS.

But there is always a 'BIOS recovery failed' message.

I tried to download recovery tool.

In the log i see that block 46 signature verification is failed.

Cannot boot up, get stuck in constant reboots.

Please help!
