Surface Pro 3 not booting

[scandisk]

Hi everyone,

three days ago i made some windows updates and on restart my surface pro 3 wont get past the surface logo, no spinning dots, nothing.

It wont even boot from rufus made windows 10 usb sticks or dvd reader.

I tried with a full discharge and with various uefi settings (like disable secure boot, delete keys etc.). I even managed to remove the screen without breaking it to disconnect the battery, but nothing seems to work.

Do you guys have an idea on what to do before i put it in the bin?

Thanks
