Dell 7520 (15r SE) BIOS checksum error

$

Hi everyone,

After sucessfully upgrading my laptops BIOS from A09 to A11 yesterday it booted normally but today it just beeps (single beep every few seconds -> ROM checksum error...).

Is there a recovery method like the Phoenix Crisis tool or such to recover a broken BIOS or can I flash the BIOS using an SPI-Flash programmer?

Thanks,

Jakob Riepler
