Bootloader Update not possible


I am following these instructions to install Ubuntu: At the moment I am already failing at updating the bootloader. I run Realterm on Windows for the steps and I am seeing d/g/r after a booting while pressing ctrl+q. After sending h and the bootloader file I only receive “fail! Invalid pkt” (see screenshot attached). Any ideas what I am doing wrong?

Thanks for your help! Best, rmk
